while(rs.next())
combobox.addItem(rs.getString("Emp_name"));

but the combobox appears consisting elements as Item1,Item2,Item3...and so on
how I can add employees names in combobox

I've been learning about the std::copy function in the <algorithm> header and I'm stuck on this exercise that I gave my self.

Let's see the code snippet first:

#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>
using namespace std;

ostream& operator<<(ostream& os, const int p_val)
{
    os.put( p_val*2);
    return os;
}

int main(/*const int argc,const char* const argv[]*/)
{
    std::vector<int> myVector = {34,54,43,2,7,87};

    std::copy(myVector.begin(), myVector.end(), ostream_iterator<int>(std::cout, " "));

    cin.get();
    return 0;
}

Basically what I'm trying to achieve is: I have a vector full of integers. I want to print the mutiply of 2 of these integers to std::cout using std::copy(). I learnt that I would have to overload operator<<(). But as you can see from my failed attempt above, I'm at a complete lost as to what I need to do insife operator<<().

Any help's much appreciated.

Cheers,
Ben

Q: malloc(0); /* What does it do? */

It's a great question because it covers a subtlety in the standard and a condition that not many people will consider. Unfortunately, I wasn't 100% confident that I remembered what the standard said about it. With full understanding that I brought the question on myself by arrogantly describing myself as an expert in C, I gave my answer as follows: "A valid pointer will be returned, but that pointer cannot be dereferenced."

My answer was wrong. The interviewer said that the result was undefined behavior, which seemed slightly off to me at the time though I didn't challenge him on a nuance I wasn't assured of. As it turns out, my answer was partially correct, though in being partially correct it was still wrong. However, the interviewer wasn't correct either. The standard states the condition of a zero size request as follows:

"If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object."

Note that implementation-defined is very different from undefined. Undefined means that the very act of calling malloc(0) invokes undefined behavior and as a result makes the entire program henceforth undefined as well. Implementation-defined means that malloc(0) is legal and doesn't affect the legality of the rest of the program, but you must take all possible results into account when making the call if you want your code to be portable. As such, the following is portable and legal, but completely useless because the pointer cannot be dereferenced:

p = malloc(0);

if (!p)
{
    /* Don't dereference p */
}
else
{
    /* Still don't dereference p */
}

If malloc(0) were undefined, the above code would be horribly broken...and still completely useless. ;) The reason my partially correct answer was wholely wrong is I neglected to account for one of two possible outcomes. And while the interviewer was technically incorrect in saying that malloc(0) is undefined, he was practically correct because thinking of a useless situation as being undefined keeps you from creating that situation. In practice, he'd potentially write better code by avoiding sending in a zero size than by accounting for the implementation-defined behavior of sending in a zero size.

Robust code is the goal. I'm not sure there's a lesson to be learned from this interview, but it is what it is. Discuss. :)

When i compile my code in Qt5, i get an weird symbol of triangle with an "?" at place of an french À. I try to chaqnge encoding to Latin1: no changes. UTF-8 it's same and i can't edit it. I tried many encoding but no changes. Weirdly months ago all worked and after i come back to the project it's dosen't work anymore and i changed nothing. Maybe an glitch/bug of Qt? Theres goes an picture of what i mean

int[7] colCountArray={0,0,0,0,0,0,0} //array saved in Board obj.

int* Board::accessColCount()
{
    return &colCountArray;

However, my compiler dosnt like this. How can I fix this problem?

Private Sub FormLoad()
Data1.Recordset.MoveFirst
R = 1: grdData.Col = 0
Do Until Data1.Recordset.EOF = True
grdData.Row = R
grdData.Text = Data1.Recordset.Fields("Name")
R = R + 1
Data1.Recordset.MoveNext
Loop
End Sub

I was wondering why my application doesn't list the changes while the application is running. For e.g I create a new job and then my application should show the new job in the list that is provided. I used ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE this but doesn't seem to work.

Thanks

After two days of struggling I have come for some help. I have a listview of contact names that I want to search with text added into a textbox. It can either filter these as the text is entered or by a button search ... I haven't got anywhere with either so far.

  private void btnSearch_Click_1(object sender, EventArgs e)
        {

            for (int i = 0; i < lvContacts.Items.Count; i++)

                if (lvContacts.Items[i].ToString().Contains(txtSearch.Text.ToLower()))
                {
                    //lvContacts.Items[i].Selected; // THIS DOESNT WORK ... as I'm sure you know
                    lvContacts.Items[i].BackColor = Color.CornflowerBlue;
                }    

        }

        private void txtSearch_TextChanged(object sender, EventArgs e)
        {
            lvContacts.SelectedItems.Clear();

            for (int i = 0; i < lvContacts.Items.Count; i++)

There is only one line to build for the test from a given dataset, but the content function has several lines.

I have a MDI application that when run for the first time it asks for the activation code by showing the main Windows Form (MDI parent) and another activation acquire code Windows Form showed above the main Windows Form using the ShowDialog() method. The main Windows Form including a tool strip button when I exit the activation Windows Form by clicking the X upper right corner button, that tool strip is disabled and I cannot use it to exit the application and when I click the X upper right corner button of the main Windows Form to exit the application it gives me an error Windows report message informing that "vshost-clr2.exe has stopped working" when I looked for the main Windows form FormClosed event I found that line of code

System.Environment.Exit(0)

What is the problem the causing such error "vshost-clr2.exe has stopped working" when clicking the X upper right corner of the main Windows Form (the MDI parent)

1. Java game
2. Use the jMonkey SDK
3. "use an existing game engine and map to modify and create your own level"
4. "The level you create must be unique, realistic and playable by multiple players"

My problem: I have spent 2 days looking for source code for java games and have not found any that fit the criteria, or are on sites that require a monthly subscription. I found some games, but they are JAR files and I don't know a way to change the files from that format. I HAVE looked at the jMonkey help files and didn't find anything.

A website, thread or instructions on how to modify a JAR file would be appreciated.

Thank you

I'm stuck somewhere. I have a table for Inventory (which contains the available amount of each food component)
What I want to do: If I select a certain food (say salad) I want to be able to deduct the components (amount) of 'salad' from the inventory table.

Consider this:
Salad is made up of 20mil of water, 50 of oil and 100gm of onion (just an example)
When I give someone a Salad, I want to be able to deduct 20mil of water, 50 of oil and 100gm of onion from the inventory table. (So that I know how much of each item in my inventory is left)

The code is to allow these recipes of Salad to be changed/deleted/some others added into it. (Flexibility). I've found this difficult since in order to allow this flexibility, I can't just write that deduction in code as something that won't change forever.(More recipes can be added in the future)

Does anyone has an idea on how to do this?

I use MySQL with VB.NET

SQLAllocHandle()
SQLSetEnvAttr()
SQLFreeHandle()

Can any onw help me understand them in detail I searched and understood them slightly. However, I'm reading a project without a documentation in which they are used and I'm confused too.... much.

Thanks in advance

1) Define a class name DVD_DB. Include the following members.
DATA MEMBERS:
Name of DVD – private character array, size 10
Price – private double variable
Quantity – private int variable
A private static int variable to keep track of how many DVD have been created so far.
MEMBER FUNCTIONS:
To assign initial values
To set price and quantity
To get price and quantity
To Print DVD
To display how many DVD has been created so far.

In main function use a DVD array and demonstrate a DVD shop. i.e. User can choose a DVD & buy it, when a DVD is sold the Quantity goes down.

Please how can I read xml files and extract image store in it and save it as .jpeg in a specified folder. Also how to export all the other fields to .csv or .txt file.

Thank you.

As in my case doing so can have unintended consequences on other applications or other areas of the server, so it bares some risk.
Hence could please advice if there is an alternative to the above query without having to add an endorsed folder in my tomcat directory.

Being primarily a community of developers and programmers, DaniWeb was historically missing one rather obvious feature: an Application Programming Interface. That glaring gap was plugged recently when Dani announced the arrival of an official DaniWeb API that enables members to put their coding skills to good use and build the DaniWeb app that they have always wanted, access DaniWeb the way they want and manipulate DaniWeb data in new and creative ways. Creativity that quickly became apparent when, within days of the API being made public, a DaniWeb moderator known as diafol (which means Devil in Welsh, and this guy is certainly a coding devil that's for sure) showcased a number of applications including a badge builder for example.

The API is very robust and capable of duplicating most read capabilities of the website itself. Additionally, there is some limited write functionality. API requests return either JSON or JSONP (for Javascript compatibility), and there is also support for OAuth 2.0 (both serverside and clientside implementations).

So what is all that stuff about 'Pwning DaniWeb' and being the 'God of Code' about then? Well, in order to help get the creative coding juices flowing, DaniWeb has launched a competition to find the best use of that newly launched API. As well as the kudos of exposing those programming skills to your peers in the DaniWeb community, the winners will also share in a $500 prize fund. The winner gets a $300 Amazon gift certificate, with a second place prize of a $125 Amazon gift certificate and third place gets a $75 Amazon gift certificate.

"There's a lot that you can do with our API. Essentially it allows your application (web, desktop, mobile, etc) to tap into DaniWeb's back end" says DaniWeb Founder and CEO, Dani Horowitz "Your own application can use DaniWeb's login mechanism, you can write a native mobile app for DaniWeb, you can create your own completely unique front-end for the site, there really are limitless possibilities". Limitless indeed. The only boundary to what can be done is your own creative flair. So whether you fancy developing an Android or iOS mobile app for DaniWeb, turning the award winning DaniWeb IT news editorial into a standalone digital newspaper, or something altogether more surprising, now is the opportunity to put your programming skills to the test.

Entry is open to all members of DaniWeb, old and new, with entries accepted until the end of August 31st, 2013 and voting taking place in September. Code submissions should be posted within the relevant code snippet library for their language whereas downloadable apps, websites, etc. should be posted within the Show Off Your Projects forum in the Business Exchange section. All submissions must be tagged with both 'daniweb-api' and 'daniweb-api-contest-submission' in order to be eligible.

More information, including usage examples, about the API is available here, and full documentation can be found here. There's also a busy thread about the competition itself in case you have any technical questions.

Remember though, the competition is only open to DaniWeb members, but as registration is free that really shouldn't be a problem for anyone who wants to get involved. So, will you pwn DaniWeb and be crowned the God of Code?

Basically, what I am trying to do is, to read a simple test.txt file's content, which are just two words actually: "Hello World" and desplay thier hexadecimal content in a shell, CMD or command line.(Whatever it is called), if the text thing is confusing you here, just think of it, as if I am trying to open a simple .wav file and read it's data and display it on CMD, like you would using

#include <iostream>
#include <fstream>

using namespace std;

int main(){

  fstream myFile;

  myFile.open("test.txt");

  //reading goes here, the problem is displaying the hex data on the editor (CMD    )

  return 0;
}

I am new to this, and downloaded codeblocks, so I can only work with the CMD as of now. I can open files with the fstream class, and write in it, but sadly I can not read it's hexa content.

Is there anyway to do this by simple means in C++?

char[10] arr="torino", *ptr;ptr = arr;cout<<&&ptr;`
and the result gives me the entire string....

The problem is with this input instance:
Input :
13
12 7 3 18 4 2 16 5 6 17 1 8 9
Output :
12 7 3 18 4 2 16 5 6 17 1 8 12
12 18 4 16 17 8 12
18 16 17 12
18 17
18
Correct Output :
12 7 3 18 4 2 16 5 6 17 1 8 9
12 18 4 16 17 8 9
18 16 17 9
18 17
18

The problem is it is turning the last element of level 0 to first element.
This is occuring at line 49. I dont know why it is changing p[0][n-1] to p[1][0].
Can any one explain the fault.
I have tested it with other inputs, its giving right answer.

you can ignore the login function as  that is just  an idea I am currently working on for the login verification

Autodesk Inventor is a 3D parametric CAD program and plugins can be made using COM. I have no experience with COM and some of my naive COM type questions go ignored in the Inventor forums...

Look at this:

  hRes = pSketches->Add (_variant_t((IDispatch *)pWorkPlane),
                         VARIANT_FALSE,
                         pSketch);
  wprintf (L"Sketch name: %s\n",pSketch->Name.GetBSTR()) ;

  pSketch->Name = L"Tube-Base" ;

  BSTR bstrSketchName ;
  pSketch->get_Name (&bstrSketchName) ;
  wprintf (L"The sketch is now called %s\n",bstrSketchName) ;

The above code shows how to get and change the name of a "Sketch" in different ways.

Basically there is pSketch->Name which is read and write, while pSketch->get_Name(&Name) is a read operation.

My question is: after using pSketch->Name do I have to do any .Release of smart pointers or anything?

Autodesk seems to have created double ways of accessing the same thing. With pointers you can use the

ptr = pObject->Get3D() ;

or

HRESULT hRes = pObject->get_3D(&ptr) ;

They reccommend the later because it does not throw exceptions. And the former I think uses smart pointers which I'm too stupid to understand.

Has anybody come across this way of doing things in COM?

I'm having some issues with getting next data from the database, it seemed to be working before, but now it doesn't change the textfields to the next data just appends the data into TextArea1 and TextArea2, the other data TextField1 etc.. Doesn't even change, so I do not know why this is happening. Been trying to figure out I can get the next data from the database for about 3 hours would really love some help.Anyone like to shine some light into this?

Thanks

i need my output to be of the form:
word,count of word in topics.txt,probability, list of files,number of files in list,

so far my program works fine till probability, but how do i get a list of the files belonging to a word?
ex: 'grain' must contain the list(5,6,....)

would counting the line number for each word and storing the line number work?

how do i go about it?

how do i rectify it?

[System.SerializableAttribute()]

//Properties section with decoration: [SoapElementAttribute(IsNullable=true)]

}

in my consumer class I obviously create an instance for this object, set all values via set properties but strangely after serialization, Property Income element is not present in the xml object graph. tried using various hacks to get this fixed an working but I'm running out of ideas because I believe theoretically and to my experience this should be working especially with SOAP serializer which serializes all public members unless cleared marked to be ignored.

tried using MustSerializeMember pattern but no luck. Has anyone ever came across such a situation or know of what could be causing this ?

I simply want to add JRadioButton and user can select any 1 row JRadioButto,

Thank you all in advance for any suggestion and guidance

Now, first of all, let me say that I don't really care about the accuracy of the carbon footprint calculation, because I am not going to build an application that somebody will actually use (there are plenty of online calculators for that), this is just an exercise aimed at helping me to understand interfaces a bit more and the usage of ArrayLists<T> which I have never used.

I had a look at how the footprint is calculated and these are the formulas I was thinking to use:
For a car:
carbon footprint = ((averageYearlyMiles * AverageMPG) * 9kg/gallon) because allegedly one gallon of gas emits 9kg of co2. (source: http://www.motherearthnews.com/nature-and-environment/carbon-footprint-calculator.aspx#axzz2WOzrsqNS)

For a house:
carbon footprint = monthly electricity kWh * 12 source http://www.howany.com/how-to-calculate-carbon-footprint/

For a bike
carbon footprint = miles * 34 (takes 34 calories to bike a mile apparently) source: http://twtitw.firebus.com/node/100

Obviously if you have any suggestion as to how to calculate that, let me know.
The questions I have are:
1) is it worth doing some pseudocode? I mean in this program I will only create some objects and then calculate the carbon footprint.
2)what sort of relevant attribute and behaviours do you think each of the classes should have? I was thinking that there won't be many. For example:
Car:
-relevant behaviours? Can't think of any
attributes:
-miles in a year
-MPG
-kg of co2 (constant amounting to 9)

Bike:
-relevant behaviours? Can't think of any
attributes:
-miles in a year
-calories per mile (constant amounting to 34)

house
-relevant behaviours? Can't think of any
attributes:
-monthly Kwh
-months (constant amounting to 12)

Is there anything else I need?
thanks

Cannot for the life of me figure out what is wrong with application, when I run on laptop cannot get error to replicate however on tablet which application is designed to run on cannot figure it out.

I have a windows form which is opened as an mdi child, it contains lots of combo boxes, check boxes, radio buttons etc... Loads fine however when the cancel button is clicked (simple Me.Close) it throws up the following JIT error:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

who has other examples of about "into"?

i want to learn!!!!!!

i am sorry to disturb to you, and also sorry to ask such a simple question!!!!!!

Has anyone used tnFox Gui Toolkit? I've just looked at FLTK which seems to be perfect if you want to creat a small file size and easy to use. I'm exploring other options like this too.

Is tnFox small in filesize. wxWidgets generates a rather big file. Has anyone used it?

Any user reviews on this would be highly appreciated. If you can suggest another type of Gui Toolkit which creates a small file, is Cross platform and has a RAD tool for building the gui and similar licensing terms (LGPL) it's something I will look into.

Thanks.

A<string, double> s1;
A<string, bool> s2;

So I wrote the A class with the necessary functions and I used a

template<class T, class E>

for it. It has a function that returns a value of E, in my case, it returns a double which I'm trying to compare to another double. I'm supposed to overload the < operator for that, but I have no idea how to do that.

4.5 < s1.at("a");

s1.at("a"); returns 1.5, so it's false. I need it to return true.
I thought since they are both double values, I can just

bool operator< (double& rhs) {
    return rhs < *this;
}

But it's not working. I also thought it should be friend with two parameters, but it just doesn't make sense since the rhs is a double returned by a function, not a type of A.
So I guess it really is two different types and that's why my first idea is not working.

Now I want to update some values. but for that i want to show the values of column_1 to column_6 in textboxes
textbox1.text
textbox2.text
textbox3.text
textbox4.text
textbox5.text
textbox6.text
against a specific ID.

i can search specific ID entered in a textbox but the result is in datagridveiw which i dont want. i want them to fill the textboxes for updation. I hope i made clear the whole scene.

When i use this code snippet(this is just a rough code snippet) i get errors like "can not find symbol GridBagContraints" and "can not find symbol TitledBorder","can not find symbol EtchedBorder". How to fix it?

I have this program but isnt runnig well. Please please help

Now, my question is that, I am untimately, learning C++ to be able to manipulate a .wav files, just to write a script from scratch and be able to read file, and illustrate in a graphical interface like a spectrogram.

But, since I am a newbie, I decided to start learning about reading binary files first, and actually used a code from this website http://www.cplusplus.com/reference/istream/istream/read/ to read a simple [code]test.txt[/code] file, which I wrote my name in, and runned the code

// read a file into memory
#include <iostream>     // std::cout
#include <fstream>      // std::ifstream

int main () {

  std::ifstream is ("test.txt", std::ifstream::binary);
  if (is) {
    // get length of file:
    is.seekg (0, is.end);
    int length = is.tellg();
    is.seekg (0, is.beg);

    char * buffer = new char [length];

    std::cout << "Reading " << length << " characters... ";
    // read data as a block:
    is.read (buffer,length);

    if (is)
      std::cout << "all characters read successfully.";
    else
      std::cout << "error: only " << is.gcount() << " could be read";
    is.close();

    // ...buffer contains the entire file...

    delete[] buffer;
  }
  return 0;
}

and It gave me, a message saying [code]Reading 32 characters... all characters read successfully.
[/code] even though, I only had like 29 characters in there. Anyway, that is not the problem.

The problem, is that, I placed a .wav file at the place where it said test.txt and even placed the .wav file in the same directory, and when I ran the code, it does not give me error or success, it shell just says, "Process returned 0 (0x0) execution time 0.008s"

What am I doing wrong? I just want to read the contents of what is in that wav file only? Be it in a frequency/amplitude/sound wave whatever the term is. Why is it not show

Q2: Write a C++ program that will read 4 integer numbers within the range of 30 to 1000, then compute and print the count of numbers that are even and dividable by 7 or 3.

Q3: Write a C++ program to find the value of Y?
Ask the user to enter an integer x from keyboard. Assume Y initially = 5

Y+=( x/100 + x/98 + x/96 + ……………. + x) + x!
Where x! Is the factorial of x.

I know it has something to do with my keyBytes variable, but how to I change it so the block size is aligned?

Here is the SimpleSymmetricExample class:

            SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");

        Cipher cipher = Cipher.getInstance("AES/ECB/NoPadding", "BC");

        System.out.println("input text: " + new String(input));

        //encryption pass

        byte[] cipherText = new byte[input.length];

        cipher.init(Cipher.ENCRYPT_MODE, key);
        int ctLength = cipher.update(input,0,input.length, cipherText, 0);

        ctLength += cipher.doFinal(cipherText, ctLength);

        System.out.println("cipher text: " + new String(cipherText) + "bytes: " + ctLength);

        //Decryption pass
        byte[] plainText = new byte[ctLength];
        cipher.init(Cipher.DECRYPT_MODE, key);

        int ptLength = cipher.update(cipherText, 0, ctLength, plainText, 0);

        ptLength += cipher.doFinal(plainText, ptLength);

        System.out.println("plain text" + new String(plainText));

    }
}

When i run it, the output is that the Glider wil move diagonally from bottom left to upper right. As it reaches the end of the field, i am required to make that it will appear again from bottom right moving to upper left. (Moves in a way that form an 'X')

Need help on how to make it appear again at the bottom left after it reaches the end of the field.

(Sorry for the crappy explanation..)

Here is the problem:

I have a switch that will turn the background service on and off. If the switch is on, i have the boolean toggleBtn set to true, and I have it set to false if the button is off. That boolean is created is the MainActivity class, but I need to access it in my service class.

like I said the problem is the switch

everything else works and/or I have not finished it yet

I'm developing a software for a furniture company for keeping furniture cost to date.I'm Saving cost with the quantity and unit price for each material and keep them up to date by updating the material's unit price.For example:
A chair need 3 Gallons of Thinner at $5,but today the price went up and it now cost $6.50.So when I update the unit price of the Thinner now the cost comes up $4.50 more.I have a Products table and a ProductMaterialCost table.What I want to do is update the Materials cost calculation and then update de Products table so the totalcost is now $4.50 more.How do I do this?Can I update the sum directly from database?

Im want to create a program for myself which will search my directories for ebooks and let me select the one i want to read. So for instance my first form has a button for C# Books, I want that then to produce a list of books found on my computer and let me pick one to read.

I know a way i can do this using oledb and msaccess and having a link field in the table. However the purpose is I do not wish to do this everytime I attain a new book.

no code snippets as of yet as i've just started the program

If anyone knows a way or can point me in the right direction, would appreciate it very much.
Cheers Guys.

So, I would like to know about the project I can start working with in GitHub to learn and develop my Java Web Development skill in Spring, JSP, Servlets and Hibernate. Please give the links of the projects and also step by step guide.

Thanks in advance.

I have the script that write log.txt in my windows 7 Desktop.

How can I change path in python to write log.txt in homedir directory? Is there any way to do it?

I tried with those 2 methods But its not work and its still write on windows Desktop?

LOG_FILENAME = 'log.txt'
#Method1
homedir = os.environ['ALLUSERSPROFILE']
LOG_FILENAME = homedir
LOG_FILENAME = 'log.txt'

#Method 2
homedir = os.path.expanduser('~')
LOG_FILENAME = homedir
LOG_FILENAME = 'log.txt'

Not sure what this error means or how to fix it but it seems that it's very common?

Any clues as to what it means. Thanks
The error is below.

I realize that it's all over the place. To be honest I'm quite stuck as to how to make the program "learn" as more people play it. Any help would be appreciated. I know that this is a lot to read and I apologize. Thanks in advance to any that help.
