himit — Fri, 18 Dec 2009 07:38:12 GMT

I am trying to transform 1 XML document to another using XSLT. I want to call the value from my source XML to the element in my result XML as the value of an attribute.

Source code-

Empire Burlesque

I don’t even know whether it is possible or not using XSLT. Please advise.

Interrupts and Exceptions

NicAx64 — Fri, 18 Dec 2009 07:05:49 GMT

Hi , these days I'm reading the brans kernel development
tutorial. and doing it's particles. So last I find to had to read
Intel 80386 programmers manual by intel.
In section 2.6 Interrupts and Exceptions I asking a theoretical question
here.
They said Exceptions are synchronous and Interrupts are asynchronous.

what that means precisely ?

Is that mean's that interrupt even can be happen middle of a instruction , but exceptions can't happen like that ? Please correct
me if I'm wrong.

Testing Equality on a BST

evilsweeps — Fri, 18 Dec 2009 07:02:26 GMT

Hi,
this is my first post on here so forgive me if my question or code is unclear.
I'm coding a binary search tree and I'm stuck on the overloaded ==operator.

//BSTCLASS.CPP

template 

void BstClass::rFindNode(node* trav,ItemType& item,node* rtTrav,

                                                                   ItemType& rtItem, bool& equal)const

{

        



        rFindNode(trav->left, trav->left->data, rtTrav->left, rtTrav->left->data, equal);



        if(item.key == rtItem.key)//Get an error here".key has no   struct/union 

                equal = true;

        else 

                equal = false;

        rFindNode(trav->right, trav->right->data, rtTrav->right, rtTrav->right->data, equal);

        





template 

bool BstClass::operator==(const BstClass& rtOp)const

{



        bool equal;



        rFindNode(root, root->data,rtOp.root, rtOp.root->data, equal);



        return equal;



}

I know the rFindNode function doesn't need all those parameters
i was just trying different things to see if i could get it to work.

my ItemType definition is in the client code per template standards

//TestClient.CPP

#include 



typedef int KeyType;



struct ItemType

{

        KeyType key;

        char data;

};





#include "bstTreeClass.h"



using namespace std;



void Display(ItemType& j);





void main() ......

My problem is that i'm getting an error when trying to assess my .key fields, I'm unclear on how i can access them so i can test them for equality

The mysterious !@#$%^ underscore

iru — Fri, 18 Dec 2009 06:38:58 GMT

Gentlefolk,

Totally new to the world of C C++, compilers and linkers.

I am attempting to compile and build some demonstration application code which access BlueTooth devices.

Have all the .C, .H files, also a .lib.

Using the LCC c ide-compiler-linker, etc on Windows-32

Compile one module - no errors.
Link the module and get a raft of undefined errors, an example:

"undefined reference to '_fred' "

'Fred' is defined in the .c file as "void Fred(void);".

I have done some research and for historical reasons some C type compilers prepend underscores to "external" symbols.

An inspection of the provided .lib file shows a number of "_Fred" symbols, unfortunately I do not have a definition of the .lib file structure to work out if things are OK. The .lib file is accessed during the link process. "Fred" and "_Fred" do not appear in a .map file.

My problem is I cannot find out how to get the linker to resolve this undefined, or perhaps stop the compiler generating such a symbol.

Any thoughts, ideas or directions appreciated.

ssh without password

johndoe444 — Fri, 18 Dec 2009 06:25:57 GMT

Hi,

The situation I am in is as follows:

There are some computers in a network. They are sharing the same file server ie the same home directory. I am not sure how it works but logging from any machine using the same user name takes me to the same home directory. Now I am trying to ssh from one machine to another because I want to run a client server application where clients and server are running on different computers. For this reason I wrote some script, to run the clients in different computers using command like this

ssh machine1 ./client.o machine0
ssh machine2 ./client.o machine0
ssh machine3 ./client.o machine0

But it asks password as a result of calling the ssh. I am not sure how to prevent machines from asking passwords. The problem is the ssh keys are stored in the same .ssh under the same home directory. Please suggest some way out of this trap.

Thanks.

Center Text inside Static Control

gretty — Fri, 18 Dec 2009 06:01:21 GMT

Hello

I have a static window control & I want to make the text inside that static window centre aligned.

Is is possible to do that with a static window?

Or should I use another function?

static window:

stBox = CreateWindowEx(

              0,

              "Static",

              s.c_str(),

              WS_BORDER | WS_CHILD | WS_VISIBLE, // maybe I can put TF_RIGHTALIGN ??

              x,y,

              w+totalW+5,h+10,

              hwnd, NULL,

              gInstance,NULL);

Another question, I have a dialog using OPENFILENAME that closes when I select a file. Is there a way to make the dialog close when I select a folder instead of a file?

void doFileOpen(HWND hwnd,UINT msg)

{

    OPENFILENAME ofn;

    char szFileName[MAX_PATH] = "";

    char folderPath[MAX_PATH] = "";



    ZeroMemory(&ofn, sizeof(ofn));



    ofn.lStructSize = sizeof(OPENFILENAME);

    ofn.hwndOwner = hwnd;

    ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";

    ofn.lpstrFile = szFileName;

    ofn.nMaxFile = MAX_PATH;

    ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;

    ofn.lpstrDefExt = "txt";



    

    if(GetOpenFileName(&ofn))

    {   

        //CommDlg_OpenSave_GetFolderPath(hwnd,sizeof(folderPath),(WPARAM)folderPath);  // This doesn't work

        SendMessage(hwnd,CDM_GETFOLDERPATH,sizeof(folderPath),(LPARAM)folderPath);

        SetDlgItemText(hwnd,msg,folderPath);

    }

    

}

While Loop Program

JuvenileMango — Fri, 18 Dec 2009 04:45:41 GMT

How can I write a definition for a function that is passed a list of numbers and returns the sum of the numbers in that list using a while loop?

I'm trying this, but it's not working

def sumList():

sum = 0
while num != str:
for i in num:
sum += i
print(sum)

Is there a way to not even use for?

C++ Function call help please

daeuse — Fri, 18 Dec 2009 03:54:50 GMT

So I'm working on my final project, and I decided to create a BMI calculator.

As part of the requirements, I need to call a function into play. Below is what I have so far, but I am getting errors. I don't expect the solution, but could someone assist me by pointing me in the right direction.

The problem is that I am not calling the function into play correctly (for starters). How do I do that?

Thank you.

how to do this in c?

johndoe444 — Fri, 18 Dec 2009 03:46:18 GMT

Hi,

In java, we can run a program remotely by doing something like this:

Runtime.exec("ssh machinename programname")

I was wondering whether I can do the same in C using some standard library function call. Also is this possible to get a handle to the remote program's input/output to see its console output or provide input (as done in java)?

Thanks.

help pls.

JAVA ATM Home problem

tabel69 — Fri, 18 Dec 2009 01:11:31 GMT

Hi out there.

I have a project that I just cant seem to get to work. I just don't get programming! I have been working on this for three days, and all I am doing is going in circles. I can't seem to get the array to initialize.

The assignment: Use the Account classes created earlier to simulate an ATM machine. Create ten account in an array with id 0,1,...9, and initial balance $100.00. The system prompts the user to enter an id. if the id is enter incorrectly, ask the user to enter a corect id. Once an id is accepted, the main menus is displace. You can enter choice 1 for viewing balance, 2 for withdraw money, 3 for deposit and 4 to exit.

my code:
import java.util.*;

public class ATM {
public class Account {
private int id;
private double balance;
private double annualInterestRate;
private final Date dateCreated = new Date();

public Account() {
}

public Date getDateCreated() {
return dateCreated;
}

public void setId(int id) {
this.id = id;
}

public int getId() {
return id;
}

public void setBalance(double balance) {
this.balance = balance;
}

public double getBalance() {
return balance;
}

public void setAnnualInterestRate(double annualInterestRate) {
this.annualInterestRate = annualInterestRate;
}

public double getAnnualInterestRate() {
return annualInterestRate;
}

public void deposit(double amount) {
balance += amount;
}

public void withdraw(double amount) {
deposit(- amount);
}

public double getMonthlyInterestRate() {
return getAnnualInterestRate()/12;
}

}

public static void main(String[] args)
{

int currentAccountId;
int currentChoice;
double moneyVariable;
boolean customerLoopFlag;
boolean validcurrentAccountID;
boolean validcurrentChoice;

Scanner input = new Scanner(System.in);

//initialize the array of accounts
Account[] customerAccount = new Account[10];
for (int i = 0; i < 10; i++)
{
customerAccount[i] = new Account();
customerAccount[i].setId(i);
customerAccount[i].setBalance((double)100);
}
//Get user data about account
do
{
System.out.println( "Enter an account number between 0 and 9: ");
currentAccountId = input.nextInt();
validcurrentAccountID = true;
if ( (currentAccountId < 0) || (currentAccountId > 9))
{
validcurrentAccountID = false;
System.out.println( "Please enter a valid account number between 0 and 9: ");
}
}while (!validcurrentAccountID);
//print customer menu
System.out.println("");
System.out.println("Main menu:");
System.out.println("1: Check Balance");
System.out.println("2: Withdraw");
System.out.println("3: Deposit");
System.out.println("4: Exit");

System.out.print("Enter a choice: ");
currentChoice = input.nextInt();
validcurrentChoice = true;
if ( (currentChoice < 0) || (currentChoice >= 4));//check to make sure it is in the range
{
validcurrentChoice = false;
System.out.println( "Please enter a valid choice between 1 and 4: ");
}
}while (!validcurrentChoice);

switch (currentChoice)
{
case 1:
System.out.println("Current Balance is: " + getID.getBalance());
break;
case 2:
System.out.print("Enter ammount to withdraw: ");
moneyVariable = input.nextDouble();
customerAccount[customerAccount].withdraw(moneyVariable);
break;
case 3:
System.out.print("Enter ammount to deposit: ");
moneyVariable = input.nextDouble();
customerAccount[customerAccount].deposit(moneyVariable);
break;
case 4:
customerLoopFlag = false;
break;

}

            Statement s = conn.createStatement();

            

            // the 1st case: create a table

            String tableName = "myTable" + String.valueOf((int)(Math.random() * 1000.0));

            String createTable = "CREATE TABLE " + tableName + 

                                 " (id Integer, name Text(32))";

            s.execute(createTable);

                     String.valueOf(Math.random()) + "')";

              s.execute(addRow);

            }

            

            // this should be third case:Fetch table

MP3 Library Program help!

MrJNV — Thu, 17 Dec 2009 23:53:56 GMT

Hi. I have this assignment and have absolutely hit a wall here. I will give the assignment details, then say what the issue is:

Consider a collection of songs in an MP3 library where each song is characterized by artistName, songTitle, album, playTime (in seconds), musicCategory, and albumProducer – hence, you will need to use a struct data type. The musicCategory is represented by an enumeration type called SongCategory. The MP-3 library can hold a maximum of 200 songs at a time. The collection of songs is stored in a text file, which you will need to create with songs of your choice. You are free to select any format by which the songs are stored in the text file.

Write a program that reads the songs data from the text file, and stores it in an array of the struct data type, each of which represents a song in the library
- PrintAllRecords: Outputs to a text file all the contents of the MP3 library
- AddRecord: Adds a new record at the end of the MP3 library.
- DeleteRecord: Removes a specific record from the MP3 library, and then shifts the array accordingly.
- UpdateRecord: For a given song record, it updates one or more fields.
- SortRecords: Sorts all the records in the MP3 library according to the name of the song artist.

Now, I cannot for the life of me get the enum to work. It doesn't display correctly, either showing a LARGE number, or repeating the wrong value for each category.
Any help to ANY of the assignment is welcomed. Thanks ahead of time. :)

Here's my code so far:

I am needing to make a program add and multiple from two different entries and display the total on a different line. I am needing the syntax on how to add and multiply. A web reference page would be good as well. All I have is two classes at this time, main and subclass. As you can see from my question I am new. Your assistance is appreciated.

Object instantiation as part of a parameter

CBLACK10 — Thu, 17 Dec 2009 22:27:54 GMT

I'm fairly inexperienced so please bear with me.

I am using FlourineFX, my goal is to retrieve data from an amf server.

I've got a windows form with a button. The code for a button creates an instance of an object:

private void btnGo_Click(object sender, EventArgs e)

{

ArrayList args = new ArrayList { val1, val2, val3, val4 };

AmfConnect VidData = new AmfConnect(args);

}





//The AmfConnect class is as follows:

public class AmfConnect

{

public  AmfConnect(ArrayList  args)

{



        ServerConnect(args);

                                          

}

private void ServerConnect(ArrayList  args)



         //get args from string array

        string server = args[0].ToString();

        string command = args[1].ToString();

        string file = args[2].ToString();



        // Create NetConnection client

        NetConnection connection;

        connection = new NetConnection();

        connection.ObjectEncoding = ObjectEncoding.AMF3;



        connection.Connect(server);

                                                                                                         

        connection.Call(command, new AmfResult(),new object[] { file, 103207, true, null, 1.859671316E9 });]

                        

}

My issue is with connection.Call. While stepping through the code, I realized that "new AmfResult()", which is where the resultant is determined, was not being processed/instantiated until after VidData was instantiated and any other code in the _Click function has been processed, keeping me from getting the resultant I need. I'm at a loss, any help would be appreciated.

Tic tac toe

zaxxon216 — Thu, 17 Dec 2009 22:00:11 GMT

I am working on the tic tac toe problem and i need help with the AI part i got it to work for 1v1 but it needs to be 1vAI

I was thinking that easiest was to to program something like "when player clicks this squaure, AI will click anything"

Should I create another temp button then everytime
tempbutton is used make tempbutton2 also move?

Belowe is the code for the clickhandler part

Thanks

private void ClickHandler(object sender, System.EventArgs e)



{



Button tempButton = (Button)sender;



if( this._isGameOver )



{



MessageBox.Show("please start new game!","Game End",MessageBoxButtons.OK);



return; 



}



if( tempButton.Text != "" ) 



{



return;



}



if( _isX ) 



tempButton.Text = "X";



else



tempButton.Text = "O";



_isX = !_isX; 



this._isGameOver = result.CheckWinner(_buttonArray );



}



}

.net 2008, application updates.

jlego — Thu, 17 Dec 2009 21:54:32 GMT

In the project properties, under public, there is a button that says 'updates' and look as to let you specify a path to an update file where the current application can compare its version information with the file in the remote update location determining if it needs to be updated.

i did something similiar to this in vb6 using an ftp server - which the .net version says that is capable of.

not getting anywhere with it though. i get errors sating public.updateurt, the stirng must be a fully qualified url or unc path.

i could program my own auto updating feature, however i would like to take advantage of the one already there.

does anyone know where there are any tutorials on the application updates or similiar, i searched google but everyhing i found was self built.

thanks

Nested Loops

tinkeydo — Thu, 17 Dec 2009 21:39:40 GMT

The first part inside the "If" statement works perfectly. The only part I am having trouble with is the "else" statement. I was trying to get it to generate an "x" amount of passwords and get those passwords to be at a length defined by the user. The problem is that it will only spew out one password. The rest have the "Password(x): " but nothing beside it. I have been through the code I don't know how many times. Would someone be able to help me? I'd greatly appreciate it. Thank you

#include 

#include 



using namespace std;



int main () {

    

    int amount, length;

    cin >> amount;

    cout << "How long would you like the passwords to be?" << endl;

    cin >> length;

    cout << endl;

    cout << endl;

    srand( time(NULL) );

    if (amount == 1) {

              cout << "Your generated password is: ";

two-pass simulation

simonsayz27 — Thu, 17 Dec 2009 21:12:20 GMT

This is starting to drive me nuts. I'm writing a program that simulates a two-pass algorithm which translates assembly language code in C++. I started with the first pass which reads the labels and address for each line. My whole program is in a mess and need a lot of help. Its supposed to read in a block of assembly code and output a symbol table in this form:

Address------- Machine code ------- Operands------- Instructions
000500 ------- 33FC --------------------- 4F------- MOVE #79, $002000

The code to translate from is:

--------- ORG $500
--------- MOVE #79, $00002000
--------- TRAP #1 ;READLN (Y), INPUT INTO DO
LOOP1 -- MOVE DO, $00020004 ;STORE DO IN LOCATION Y
--------- MOVE $00002000, DO ;FETCH VARIABLE I FOR THE AD
---------ADD $00002004, DO ;ADD Y+1
---------MOVE DO, $00002002 ; STORE THE SUM IN X
LOOP2 -- ADDI #18, $00002002 ;ADD 18 TO X
---------TRAP #2 ; PRINT X
----------- TRAP #0 ; STOP
----------- END

Here is where I am so far. I can't find any tutorials online for the SMC 68000 so if you know of any or can help me out in any way I would REALLY appreciate it.

Sales problem c++

kellnerq — Thu, 17 Dec 2009 21:06:47 GMT

Hi together i need your help... again for my lab work.
The question is the following:

Use a single-subscripted array to solve the following problem. A company pays its
salespeople on a commission basis. The salespeople receive £200 per week plus 9 percent of
their gross sales for that week. For example, a salesperson who grosses £5000 in sales in a week receives £200 plus 9 percent of £5000, or a total of £650.
Write a program (using an
array of counters) that determines how many of the salespeople earned salaries in each of the
following ranges (assume that each salesperson’s salary is truncated to an integer amount):
a) £200–£299
b) £300–£399
c) £400–£499
d) £500–£599
e) £600–£699
f) £700–£799
g) £800–£899
h) £900–£999
i) £1000 and over

Sample Screen Output

NullPointerException

benregn — Thu, 17 Dec 2009 20:56:08 GMT

Hi, I'm getting this NullPointerException in one of my classes (state). This design is done by a state machine design pattern. From debugging it I can see that insertMoney under coffeemachine>State>insertMoney is null but I can't figure out why it's null.

The line with the error is almost on the bottom and marked with ERROR.
Error message:

Exception in thread "Thread-3" java.lang.NullPointerException

        at hotdrinksmachine.MessageDelay.run(InsertMoney.java:102)

        at java.lang.Thread.run(Thread.java:619)

This is my first semester in Java so please help! :)

I attached my project from NetBeans and also just the .java files.

VB.net 2008 and XML problems

TheMightySpud — Thu, 17 Dec 2009 20:40:17 GMT

Hi all,

I hope someone can help me with this because it's driving me insane.

I've spent almost two solid days trying to figure this out without much success.

What I need to do is load in an XML file (which I have working fine) but then I need to cycle through each element and extract each of the childnode values into it's own textbox so the user can then edit the values and save the edited XML file.

The XML file looks like this (it has been edited down a little)





        35

        6

        yes

        no

        yes

        



                

                        BG

                        image

                        1

                        Background.png

                        720

                        576

                



                

                        Big text

                        label

                        200

                        355

                        200

                        #highlightedbutton

                        center

                        dingbats

                        40ffffff

                WindowOpen

                            WindowClose

                



        common.videowindow.small.xml

Each of the 'control' elements can potentially have a different number of childnodes. which is my first problem.

Also, there can be varying numbers of 'control' elements

I sort of have an idea in my head of how to achieve what I want, but don't have the first clue on how to do it.

Bascially what I want to do is determine the number of 'control' elements (which I have done) and then create a new 'tab' for each one.

Within each individual tab I want to create a text box and a label for each 'control' childnode title (label) and value (textbox), the user will be able to then edit these values and then click a button to save the XML file.

Here's where I am with the vb.
At the moment, it loads the XML and determines how many 'control' elements there are.

Public Class Form1



    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load



        Me.cmbFolders.DataSource = (From folder In New IO.DirectoryInfo("C:\ProgramData\Team MediaPortal\MediaPortal\skin\").GetDirectories Select (folder.Name)).ToArray



    End Sub



    Private Sub cmbFolders_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbFolders.SelectedIndexChanged



        Dim str_SkinName As String

        Dim str_SourceFolder As String

        Dim str_CurrentSkin As String

        Dim str_FileName As String



        Dim intControlCounter As Integer



        Dim xmlDoc As New XmlDocument



        Dim teststring As String



        teststring = ""



        str_FileName = "BasicHome.xml"

        str_SourceFolder = "C:\ProgramData\Team MediaPortal\MediaPortal\skin\"

        str_SkinName = cmbFolders.SelectedValue



        str_CurrentSkin = str_SourceFolder & str_SkinName & "\" & str_FileName



        txtFilePath.Text = str_CurrentSkin



        xmlDoc.Load(str_CurrentSkin)

        intControlCounter = xmlDoc.SelectNodes("window/controls/control").Count



        txtControlNo.Text = intControlCounter



        'MsgBox(xmlDoc.OuterXml)



    End Sub



End Class

Stopping a shape after 5 seconds of moving

Lida_pink — Thu, 17 Dec 2009 20:35:24 GMT

How can I stop shape after 5 seconds of moving?

I know how to move it and how to stop it but don't know how to make it stop IN 5 SECONDS.
This is the rest of the code that I have done but the 5 seconds part is still left. BTW, I tried to use loop but it didn't work out.
Thanks everyone in advance. :)

Private Sub Command1_Click()
Timer1.Enabled = True
End Sub

Private Sub Form_Load()
Command1.Caption = "Move"
End Sub

Private Sub Timer1_Timer()
Shape1.Left = Shape1.Left + 50
End Sub

WINAPI question : Running an exe

CodyOebel — Thu, 17 Dec 2009 20:33:39 GMT

Ok so heres what I am trying to do to help you understand my question. I am making my WINAPI load hidden so it's not in the taskbar and is only running as a process using ShowWindow(hwnd, SW_HIDE) on case WM_CREATE:

Now what I am trying to do is make my api run a file on my c:\ .
For example I got a program that I use that is a mouse macro recorder. It records mouse clicks and movements etc.. and it saves the recorded file as c:\ace.scp . So if I clicked on c:\ace.scp the recording runs the recorded clicks and so forth, and if I run c:\ace.scp through command line console it runs etc.. but what I am trying to do is make my api run it. So in my api as with my console experience what I did was placed system("c:\ace.scp"); right under my WM_CREATE case, and it runs the ace.scp, but it keeps a console window open. I dont want the console window open at all. Is there a way to run the ace.scp, or any executable without using system("DPATH"); ??? Like an windows API version that doesnt execute the program through an obvious console?

I'm really hoping to get a simple function that can do this and not a huge block of code, but either way whatever works.

Need help with pygame to exe

sinisterduke — Thu, 17 Dec 2009 20:26:00 GMT

So i made a small game using pygame, and I want to be able to give it out to some friends who don't have python, so I want to make it into an EXE. i've been trying for several hours using several different methods, but nothings seems to be working. I would REALLY appreciate any help.

So after all this time I think py2exe appears to be the best tool to use. I have it installed, I just can't get it to work correctly on my game. After looking for many different setup.py file thingys, this is the one i've been using most recently:

if __name__ == '__main__':

        if len(sys.argv):

                sys.argv.append('py2exe')

            BuildExe().run()

            raw_input("Press any key to continue") #Pause to let user see that things ends

When I try this however, I get the error:
NotImplementedError: font module not available
(ImportError: MemoryLoadLibrary failed loading pygame\font.pyd)

In my actual code, I'm loading font using:
font = pygame.font.SysFont("freesansbold", 48)

as I heard this is the better way to do it.

I've tried many different setup.py files, but each gives me a different error, whether it be missing DLL's, or font, or something else. If I could get any help with this, i would appreciate it.

Checking the MySQL Database

Dmennite — Thu, 17 Dec 2009 20:24:17 GMT

Hello all,

Not sure if this is the proper forum for this but first:

I am using Visual Studio 2008 and MySQL Server Version 5.1.42 and Client Version 5.1.11 programming language C#

issue:
save button from windows form for record editing using databindings and textboxes...

is there a way to check if the value in the textboxes match the field in the database so it does not overwrite the field if it has not been changed.

I had thought about creating a stored procedure that throws the fields into strings which then could be checked if each equals corresponding textbox.text...
if so do nothing otherwise update that field...

I see alot of redundant coding to accomplish this this way... was wondering if someone had an idea that would require less coding within my program...

for example:

private void btnSavDealer_Click(object sender, EventArgs e)

        {

            //Are you sure box

            DialogResult dlgResult = MessageBox.Show("Are you sure you wish to save changes to this Dealer?", "Continue?", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

            if (dlgResult == DialogResult.No)

            {

                // No, Do nothing and set focus back to dealer name

                txtDealName.Focus();

                txtDealName.SelectAll();

                return;

            }

            else if (dlgResult == DialogResult.Yes)

            {



                //Create Database connection

                MySqlConnection conn = new MySqlConnection("server=localhost;user id=root;Password=******;persist security info=True;database=central1;");



                //get Dealer Name from Database

                try

                {

                    conn.Open();

                    MySqlCommand myCommand = new MySqlCommand(spname, conn);

                    myCommand.CommandType = CommandType.StoredProcedure;

                    myCommand.Parameters.AddWithValue("@dealerID", lblDealNum2.Text);

                    myCommand.Parameters["@dealerID"].Direction = ParameterDirection.Input;

                    myCommand.Parameters.Add(new MySqlParameter("@dealername", MySqlDbType.VarChar));

                    myCommand.Parameters["@dealername"].Direction = ParameterDirection.Output;

                    myCommand.ExecuteNonQuery();

                    dn = (string)myCommand.Parameters["@dealername"].Value;

                    conn.Close();

                }

                catch (MySqlException MyException)

                {

                    MessageBox.Show("Stored procedure error: MySQL code: " + MyException.Number

                                      + "  " + MyException.Message);

                    conn.Close();

                }



                // MessageBox.Show(dn); //Test to make sure retrieving correct name



                //Dealer Name

                if (txtDealName.Text == "")

                {

                    MessageBox.Show("You must enter a name for this Dealer.");

                    txtDealName.Focus();

                    txtDealName.SelectAll();

                    return;

                }

                else if (txtDealName.Text == dn)

                {

                    //Do nothing

                }

                else

                {

                    //MessageBox.Show(txtDealName.Text); //More testing

                    string query = "UPDATE dealer SET DealName = '" + txtDealName.Text + "' WHERE DealNum = '" + lblDealNum2.Text + "'";

                    MySqlCommand cmd = new MySql.Data.MySqlClient.MySqlCommand(query);



                    try

                    {

                        conn.Open();

                        cmd.Connection = conn;

                        cmd.ExecuteNonQuery();

                        conn.Close();

                    }



                    catch (MySqlException)

                    {

                        System.Diagnostics.Debugger.Break();

                    }

                }

                this.Close();

            }

        }

This one works but uses a single query stored procedure that returns only dealer name...

Class to Compute Average

lkegley — Thu, 17 Dec 2009 19:50:40 GMT

Hi All,

Thank you for reading this and helping me! I am finishing off my program with a method that can compute Average Scores from a list of data. It's giving me an error that says "invalid use of member (did you forget the â&â ?)". Below is the code that I'm working on, the
error is the line with the Sum =. Please Help me figure out a way to sum up all the scores successfully!

int Team::AverageHome()

{

int Average = 0;

int Sum = 0;

int Number = 0;

int i;



        for( i = 0; i < NumGames; i++)

        {

                Sum = Sum + Games[i].GetHomeScore;

        }



        Average = Sum / i;



        return Average;

}

Need Help With Templates and Vectors

prokek — Thu, 17 Dec 2009 19:44:33 GMT

Hi, I'm trying to write a console program that will sort and find the median of numbers that are given in a text file. The text file can have ints or doubles.

The problem I'm having is outputting the median and the insertionSort functions. I think that they are failing because I did something wrong with either the vector or templates or both as it is my first time writing code using both of those.

Any insight is greatly appreciated.

#include 

#include 

#include 

using namespace std;



template

        {

                in_file >> a_value;

                values.push_back(a_value);

        }

}

int main() 

{

        vector values;

        char filename[16];

        cout << "Enter a file name: ";

        cin >> filename;

        cout << endl;



        ifstream fin(filename);

        if (!fin) 

        {

                cerr << "Could not open the file" << endl;

        vector::iterator p;

        for (p = values.begin(); p != values.end(); p++) 

        {

                cout << *p << ",";

        }

        cout << endl;





        cout << "Sorted values are: " << insertionSort << endl;

        cout << "Median = " << median << endl;



} //end main









template 

void insertionSort(vector& values)

{

        

        int i, j, n = values.size(); //i is the pseudo-Code Index and j is the scanIndex

        T temp;

        // Select List[Index] as element to be inserted into sorted sublist.

        // so it is in the correct position

        for (i = 1; i < n; i++)

                }

                // the location is found; insert temp

on a form in access, I open up a rst and want to send a report to all in a database table list.

It all works and opens outlook and will send it but, it shows the security thing>>>

then, access moves on the the 2nd report and then , it shows the security thing>>>

after I click "allow", it goes ahead and puts the 2nd email in "outbox".

then, access moves on the the 3rd report and then

etc.. I really don't want the user to have to wait and click this 37 times to complete the task..

KochCurve Coding! NEED HELP!

gods_angel — Thu, 17 Dec 2009 19:05:40 GMT

ok so here are the instructions for this project:

Write a KochCurve program that uses DrawingTool and provides a drawKochCurve method for drawing Koch curves. Each drawKochCurve method can take the number of levels and an initial size as its parameters. Sample usage of the method to draw a 6 level Koch curve of length 300 would be:

KochCurve curve = new KochCurve();
curve.drawKochCurve(6, 300);

The procedure for creating a Koch curve is usually recursive. At each level, we observe that a Koch curve is made up of four smaller Koch curves. This process can be described in the following pseudocode:
if level < 1 then
Move forward length pixels
else
Draw a k-1 level Koch curve with segments 1/3 the current length
Turn left 60 degrees
Draw a k-1 level Koch curve with segments 1/3 the current length
Turn right 120 degrees
Draw a k-1 level Koch curve with segments 1/3 the current length
Turn left 60 degrees
Draw a k-1 level Koch curve with segments 1/3 the current length

Discriminating between Windows versions programatically

donaldw — Thu, 17 Dec 2009 18:33:47 GMT

I've pretty much got it down how to determine operating system version, service pack level, 95/NT based, etc. for Windows XP and earlier versions by using GetVersionEx(...) and that's pretty handy for getting system information that software users probably don't know and don't know how to figure out (sadly).

A new wrench in the works is driver signing enforcement on 64 bit versions of windows (e.g. Windows Vista Home Premium 64-bit), which requires drivers to be digitally signed (read: 30 pieces of silver to MS and their cronies) which, by the way, Kaspersky and other AV folks say doesn't do squat for preventing malicious code from executing.

Driver signature enforcement may be disabled by the user at boot time using the F8 key and selecting the appropriate option, but that is inconvenient and impractical for the user. There is also a work around which can be used after the fact for this particular driver (which involves installing the signed drivers and the unsigned drivers, which are the same drivers only modified to include my PID and VID).

In any case, it would be easiest if we were able to determine the version of the operating system and resolve it down to the OS major and minor version, service pack, on which OS it is based as well as 32- vs 64-bit. Which leads to my question: How do I do that?

I think I'll need to use the GetProductInfo(...) function (?) but I'm not sure if that will do the trick or not and, further, I'm not sure how to use it and can't find any really good examples. Does anyone know if this will work and, if so, can you explain/show me how to do it? Is there another, easier, way to determine this information programatically? I'm using VC++ 6.0.

Text files and Array

su-moose — Thu, 17 Dec 2009 17:29:25 GMT

Hello.. This is my first time posting here, and I'm hoping I can find some help

I have missed about a week and some of my programming class, and I am very behind. I haven't been able to figure these out on my own.

I need to write a practice program that prompts the user to enter an Element Name, the Symbol and the Atomic Mass, in a procedure. It also needs to offer the list sorted by Element Name, and Atomic Mass.

Basically, I need to create/ overwrite a file, a readln to enter the Element Name/Atomic Mass/Symbol, and have the option to display by Element Name, and by Atomic Mass.

I know that I need to use a basic array, and I know how to create a text file and overwrite it, but after my absence, this is overwhelming.

Thank you in advanced

Custom Installation Questions

JuvenileMango — Thu, 17 Dec 2009 17:04:03 GMT

Hi, I'm completely new to Java, and I'm already lost with the installation. :p

I'm on the custom install page and I see

Source Code: Source code for classes that comprise the public API of Java.
Public JRE: The standalone JRE. Any application can use this JRE. It registers Java Plug-in and Java Web Start with the browsers and system.

There is also Demo and Samples, and Development Tools, which don't have an option for not installing.

I don't know if I should install those two features.

Reading CSV into Dataset (BES Log files)

jonturlington — Thu, 17 Dec 2009 17:01:23 GMT

It gives an incorrect row count and the column count only shows 1.

So when I try to handle the true number of columns in the CSV file it reports an OutOfIndexRange error.

Any and all help would be greatly appreciated.

py2exe and tkSnack

yvos91 — Thu, 17 Dec 2009 16:51:58 GMT

Hello everybody,

I made a wonderfull software, using Windows / python26 / tkinter / tkSnack.
As long as I'm on my computer, it works fine.
I try to distribute it, using py2exe. And I've not found the way to include tkSnack in the distribution.
I tried also with pyInstaller, with the same result.

I guess there is something to write in the setup file, like packages="tkSnack".

Does someone have an idea ?

nb : sorry for my poor english

2d linked lists(??)

RichardCrickets — Thu, 17 Dec 2009 16:45:28 GMT

Hello,

I am trying to create a collection that will store boolean relationships between a list of numbers. Normally I would create a 2d array but these numbers will always be dynamically changing. Sometimes there will be more numbers and sometimes less. What collection type can I use to store an unspecified amount of data that behaves like a 2d array??

String Program Problem!

nedsnurb — Thu, 17 Dec 2009 16:43:11 GMT

hi,
the following program has got to take a user inputted string and allows the user to see the postion of each character in the array i.e.
T H I S I S A T E S T
0 1 2 3 4 5 6 7 8 9 10 11 12

then it ask the user to search for any of the characters and it gives them their first and last position i.e for T 1st =0 last = 12

then it has to reverse the string. At first I had this working in one class, but I now need to split it into seperate cpp and header files.

but now i'm getting errors that i'm have problems fixing, probably something simiple that i just can't see.

Here are the 3 seperate files:

Help with my code

letlet_pogs — Thu, 17 Dec 2009 16:08:18 GMT

Hello good day guys. I just want to ask for help in my java python. I am just new in this language.
MY first java language is java. However, for me to make it easier to code in python, i need to code it in java first and then convert after. But i am confused working with arrays in python, help me guys. Thank you.

import java.util.*;



public class sample {

        static Scanner scan = new Scanner(System.in);

        

        public static void main (String args[]){

                sample();

        

        }

        public static void sample(){

                

                System.out.println("Enter numbers : ");

                String input[] = new String[5];

                for ( int i = 0 ; i < input.length; i++){

                        

                        input[i] = scan.nextLine();

                        

                }

                for ( int i = 0 ; i < input.length; i++){        

                        System.out.println(input[i]);

Random in Class

Skeen — Thu, 17 Dec 2009 16:03:07 GMT

Okay, I'm making a game, and I need to use random inside a class, however I can't figure out how to seed the randomness into the class, so atm I'm getting the same random each time. I've tried stuff like srand(time) in main, however, that doesn't apply to the class, so how am I going to seed it in the class, call srand inside the constructor?

lenb vb6 vs .net

jlego — Thu, 17 Dec 2009 15:49:55 GMT

in vb6 the most efficient/fast way to test if a variable/object was empty was to use

-
VA Circuit
-
VARDOS,BENSON
01/01/1901
123-45-1234
MALE
WHITE

UNKNOWN
000
000

123 APPLE ST ,RICHMOND VA 23232

112233
Offender#: 001 CASE#:112233

Here is the linq query:

 ListBox1.Items.Clear()

        Dim feedXML As XDocument = XDocument.Load("c:\mydata.xml")

        Dim sb = New StringBuilder()

        For Each s In (From nbdresponse In feedXML.Descendants("record") _

        Where (nbdresponse.Element("jurisdiction").Value() = Me.DataGridView3.CurrentCell.Value) _

        Select nbdresponse.Elements("offender").Value())

            sb.Append(s)

        Next



        Dim foo = sb.ToString

        ListBox1.Items.Add(foo)

and it is returning:

VARDOS,BENSON01/01/1901123-45-1234MALEWHITEUNKNOWN ..... ETC.

where as I need it to be
VARDOS, BENSON
01/01/1901
123-45-1234
MAIL
WHITE
UNKOWN
ETC.

i am also not apposed to putting this into a gridview as multi rows. But I am lost. Any advice? Any research directions i can take?

jComponents jumping around on the Gui

P00dle — Thu, 17 Dec 2009 14:57:12 GMT

I've made a gui that has a couple of panes on a frame.

Initially only one frame is visible, but as you fill in options and press buttons, the others become visible.

The problem I have is that the first pane should be in the top left corner when the app starts up. It's not doing that though, when it starts up it's at the top right, and only shifts to the top left when the other pane become visible. Is there any way for me to fix this?

Thanks in advance!

I need your view on this project

evstevemd — Thu, 17 Dec 2009 14:41:28 GMT

Hi guys,
I have always wanted to write MP3 encoder in Python. I heard of Py-lame but I have never had hands on it and it is, to me a myth.

Ok after trying thinking in ctypes, I thought the best way would be using lame.exe and subprocess. But as I'm thinking of it, I hate black screen. I want to use my own GUI using wxPython. So, is it possible to use subprocess without having black screen? Also getting encoding progress and nicely display it on progress bar?

What do you suggest buddies? Thanks alot ;)

Help with Python

pith — Thu, 17 Dec 2009 14:07:24 GMT

Hello, I need help with editing this program:

#!/usr/bin/env python

"""

Monte Carlo simulation for the Monty Hall Problem:

http://en.wikipedia.org/wiki/Monty_Hall_problem.

"""

import sys

from random import randrange, shuffle, choice



DOORS = ['car', 'goat', 'goat']



def pick_door():

    """Return a number representing the player's first choice."""

    return randrange(3)



def reveal_door(pick):

    """Return the index of the door opened by the host.

    This cannot be a door hiding a car or the player's chosen door.

    """

    all_doors = set([0, 1, 2])

    unavailable_doors = set([DOORS.index('car'), pick])

    available_doors = list(all_doors - unavailable_doors)

    return choice(available_doors)



def staying_wins(pick):

    """Return True if the player won by staying

    with their first choice, False otherwise.

    """

    return won(pick)



def switching_wins(pick, open_door):

    """Return True if the player won by switching,

    False otherwise.

    """

    other_doors = set([pick, open_door])

    switched_pick = (set([0, 1, 2]) - other_doors).pop()

    return won(switched_pick)



def won(pick):

    """Return True if the player's final pick hides a car,

    False otherwise.

    """

    return (DOORS[pick] == 'car')



def main(iterations=1000000):

    """Run the main simulation as many

    times as specified by the function argument.

    """

    shuffle(DOORS)



    switching = 0

    staying = 0



    for dummy in xrange(iterations):

        picked = pick_door()

        revealed = reveal_door(picked)

        if staying_wins(picked):

            staying += 1

        if switching_wins(picked, revealed):

            switching += 1



    staying_rate = (float(staying) / iterations) * 100

    switching_rate = (float(switching) / iterations) * 100



    print "Staying: %f%%" % staying_rate

    print "Switching: %f%%" % switching_rate



if __name__ == "__main__":

    if len(sys.argv) == 2:

        main(int(sys.argv[1]))

    else:

        main()

You can probably tell what this program does so I shall not elaborate. However, how can I edit the program so that it works for (for example) 4 goats and 1 car? Of course

DOORS = ['car', 'goat', 'goat']

needs to be changed but I'm not sure what else. Also, what does

return randrange(3)

do?

Thanks :)

Image Problem with Tkinter

Ash_Pokemaster — Thu, 17 Dec 2009 14:04:46 GMT

Hello pals.

We're having a project to make a Backup and Restore program in Python. As we think that making a GUI is of course very important, we started using Tkinter after initially trying wxPython which was kind of difficult given the time we had.

Either way, we made a Class where the main window is. Inside this Class, there is another Class defined, which contains the code of the another Window, where one can chose the options of the backup proccess. So, here's the thing. While we have made two text entries and two buttons, when trying to load an image, or any label for all it matters, it just won't appear, and we get the following error in Python Shell.

Exception in Tkinter callback

Traceback (most recent call last):

  File "C:\Python25\lib\lib-tk\Tkinter.py", line 1414, in __call__

    return self.func(*args)

  File "C:\Users\Ash_Pokemaster\Desktop\project_e31\kuygku.py", line 110, in backup_window

    back = Backup(buwind)

  File "C:\Users\Ash_Pokemaster\Desktop\project_e31\kuygku.py", line 94, in __init__

    self.labelcho = Button(framebu, image= photocho)

  File "C:\Python25\lib\lib-tk\Tkinter.py", line 2012, in __init__

    Widget.__init__(self, master, 'button', cnf, kw)

  File "C:\Python25\lib\lib-tk\Tkinter.py", line 1942, in __init__

    (widgetName, self._w) + extra + self._options(cnf))

TclError: image "pyimage8" doesn't exist

Here is the code along with the images.
http://rapidshare.com/files/32165819...t_e31.zip.html

We would appeciate it if you could try create an image inside the Backup Class, and figure out what the problem is.

So far, this is what we type between the two text entry eidgets, and of course doesn't work:

                photocho = PhotoImage(file=choose.gif")

                self.labelcho = Button(framebu, image= photocho)

                self.labelcho.image = photocho

                self.labelcho.pack()

                self.labelcho.grid(row=2, column=0)

Image "choose.gif" is not inside the zip, but I guess any image would work...

Thanks for your time.

warning: taking address of temporary

Japus — Thu, 17 Dec 2009 13:33:47 GMT

Hello

I'm trying to copy a variable from a vector into an array (with a few steps in between)
As you can see from the code, I take a random piece of equipment from the vector of equipments and insert it into the inventory (which is an array).
The line marked with the <---- gives a warning in the compiler.
warning: taking address of temporary

// Static list of monsters & equipment

vector monsters;

vector equipments;

vector potions;

vector bags;



template 

void load_from_file(vector & v, const char * filename) {

        ifstream in(filename);

        if (!in.is_open())

                throw runtime_error(string("File does not exist: ") + filename);



        string line;

        while (getline(in, line)){

                if (line[0] == 'P'){

                        potions.push_back(CPotion(line));

                }

                else if (line[0] == 'Z'){

                        bags.push_back(CBag(line));

                }

                else{

                        v.push_back(T(line));

                }

        }

}



template 

T random_from(const vector & v) {

        return v[d(1, v.size()) - 1];

}



void Battle(CPlayer player, int count){



// code omitted



        if (count > 1 and player.Alive()){

        // generate an amount of gold

                int amt = rand()%100;

                player.Receive(amt);

                cout << "You get " << amt << " gold from the " << monster.GetName() << endl;

        // less money is compensated with a weapon

        //if (amt < 20){

                CEquipment* equipment = &(random_from(equipments)); //<-----

                cout << "You search the room and find: " << *equipment << "."<< endl;

                cout << "What do you do? (e)quip, (c)ontinue, add to (i)nventory " << endl;

                cin >> move;

                switch (move){

                        case 'e': 

                        player.WieldItem(*equipment);

                        break;

                        case 'i':

                        player.AddToInventory(equipment);

                        player.DispInv();

                        break;

                        default:

                        break;

                }



        //}

        }

        else {cout << "You survived the dungeon!" << endl << "Your final stats: " << player << endl;}



// code omitted



}

When I print out the inventory after one addition, its correct but after the second addition it says that both elements are the same and equal to the last added item.

How can I resolve this issue? I know the inventory works as it should, the display function is also correct.
I thinks its something with the fact that the equipment from the vector is given through a few functions. But I don't see the solution.

Thanks,

Jasper

Controls position when is shown in mdiParent Form . How to Resolve this Issue?

nauman_gcu — Thu, 17 Dec 2009 12:55:57 GMT

I have Windows Form which is implemented as per singleton pattern and having TableLayoutPanel as container on it for other controls to be placed on it and it is generating an anonymous problem regarding controls movement in which they changes their position when set as mdiChildForm of a mdiParent Form. In this scenario if a windows Form is not being implemented by singleton pattern then it is working fine and if not then the Controls like lable and others are changing their location when the form appear on screen inside mdiparent second time by the user. The further detail regarding this problem is described below.

There are two Forms named as UI-1 and UI-2 and one Is the MDIParent Form named as MainForm.

Form UI-1 has the singleton pattern implementation and can only be initialized by GetInstance() method as you can see from code given below.

The code In the UI-1 Form:

     public partial class UI1 : Form

    {

        private static UI1 frm;

     

        public static UI1 GetInstance()

        {

            if (frm == null)

            {

                frm = new UI1();

            }

            return frm;

        }



        private UI1()

        {

            InitializeComponent();

        }



        public void ShowLabelCoordinates()

        {

            MessageBox.Show("Location: " + this.label1.Location.ToString() + " Position: "+ 

              this.label1.PointToScreen(this.label1.Location).ToString());

        }

    }





Form UI-2 is with its usual constructor and can be initialized directly from it as you can see from code given below.



public partial class UI2 : Form

    {

        public UI2()

        {

            InitializeComponent();

        }

    }



The code in the main Form which is actually a mdi Parent Form.



UI1 frm = UI1.GetInstance();

            frm.MdiParent = this;

            frm.Show();

            frm.Focus();

            frm.ShowLabelCoordinates();



UI2 frm = new UI2();

            frm.MdiParent = this;

            frm.Show();

            frm.Focus();

Any immediate assistance will be highly appreciated.

Sharepoint Session Variables

brimble2010 — Thu, 17 Dec 2009 11:55:37 GMT

Hi all,

I am currently developing a webpart that works as a submit for many web parts at once.

When the Submit button is pressed, it sets a session variable and then when the page is realoded, each form on the screen responds to this and calls their own Submit functions.

For somereason when trying to turn these variables off again (in RenderWebPart) I get a SP error that says that there is a problem with the webpart (No other information given).

The reason that the variable is turned off in RenderWebPart is so that all webparts can call their submit function in OnPreRender and then the variable is turned off when I know all have completed their submits.

Here is the code for the RenderWebPart function, I was wondering if anyone could help point me in the right direction for solving this issue.

Protected Overrides Sub RenderWebPart(ByVal output As HtmlTextWriter)



        EnsureChildControls()



        Me.Page.Session.Item("GlobalClear") = "Off"

        Me.Page.Session.Item("GlobalClose") = "Off"

        Me.Page.Session.Item("GlobalVerify") = "Off"

        Me.Page.Session.Item("GlobalSubmit") = "Off"



        MyBase.RenderWebPart(output)



        If mstrNextPage <> "" Then

            Me.Page.Response.Redirect(mstrNextPage)

        End If



    End Sub

Thanks

leap year

seam — Thu, 17 Dec 2009 11:48:49 GMT

Project 1
Leap year calculation (Leap year is a year that has 366 days, a year that has 365
days is not a leap year)
Write a program that will accept a positive integer ( the year to be tested) from a user. If
the user inputs a 0 or negative number, the program quits without doing anything.
Otherwise, it will print a message saying whether or not the year is a leap year based on
the following rules.
The rules to calculate if it is a leap year are:
(a) A year divisible by 4 is a leap year (2004, 2008...), unless
(b) it is also divisible by 100 (2100, 2200...) in which case it is not a leap year.
(c) There is an exception. A year divisible by 400 is a leap year (2000, 2400...).
Here are examples of how the program works.
Input a number for the year (>= 1): -1
Sorry, your year must be greater than 1.
Input a number for the year (>= 1): 2001
The year 2001 is (a leap year) or ( not a leap year)
Input a number for the year (>= 1): 2004
The year 2004 is (leap year) or ( not a leap year)
Input a number for the year (>= 1): 2100
The year 2100 is not a leap year

[pyqt]QTabbar beginner question..help plz..

python.noob — Thu, 17 Dec 2009 11:29:16 GMT

Hello all,
One simple question.. We can set Tab bar for the tab widget in pyqt...
I want to place a push button on tab1.. In what way i can do that??? Should i have to add this in the first tab in tab bar or in the tab widget directly.. If i'm not clear, in QTabWidget we will add the components in this sequence
CreateWidget-->Add it to the tab(addTab)--->Add it to the QTabWidget..

In the same manner how should i use QTabbar..
CreateWidget--->Add to TabBar--->Add it to the Tab(in Tab Widget)
or
CreateTabBar---->SetTabBar and CreateWidget---->Add to the TabWidget ...
Explain me in detail...
