That post didnt help but thanks!

 Private networkAvailableEventHandler As NetworkAvailableEventHandler = AddressOf NetworkConnectionChanged

 Private Sub NetworkConnectionChanged(sender As Object, e As NetworkAvailableEventArgs)
        If Not disposed Then
            OnPropertyChanged("IsNetworkAvailable")
        End If
 End Sub

 Dim disposed As Boolean = False
    Public Overloads Sub Dispose() Implements IDisposable.Dispose
        Dispose(True)
        MyBase.Dispose()
        GC.SuppressFinalize(Me)
    End Sub

    Protected Overridable Overloads Sub Dispose(disposing As Boolean)
        If disposed = False Then
            If disposing Then
                RemoveHandler My.Computer.Network.NetworkAvailabilityChanged, networkAvailableEventHandler
                networkAvailableEventHandler = Nothing
                disposed = True
            End If
        End If
    End Sub

    Protected Overrides Sub Finalize()
        Dispose(False)
    End Sub

I have something close to above, my problem is, even after disposing the whole object the EventHandler invoke the NetworkConnectionChanged method even after removing the address.

any clues?

Hey guys,
I am trying to use TextInputPanel for passwordbox but since its part of WPF it does not allow us to use TextInputPanel. I followed the following link

http://interactiveasp.net/blogs/natesstuff/archive/2008/10/01/ink-in-wpf-using-textinputpanel-for-text-input.aspx

this works fine with the textbox but not with passwordbox, I modified the class to accept password boxes but when I focus on the passwordbox the TextPanelInput icon does not appear, can anyone help?

that is great if you could explain the logic in words? I know for loop is simple for loop that is just iterating through the list until the end, then if prev is not equal d then check if prev? what is that if doing? Thanks

this is third time I am trying to post,

can you explain

if prev != d:
    if prev:
        print prev, count
    prev = d
    count = 0
count += 1

how that is working?

I guess this would explain better, following is my output that is printing each element in the list and printing the count of the element its working fine if you see 2.0 just had one occurance and so it was printed with 1 and rest of that had more occurances they were printed with their count. What I want is to keep the count same but instead of printing duplicates just print one unique

2.0 1     2.2 3     2.2 3     2.2 3    2.3 4    2.3 4    2.3 4    2.3 4    2.4 3    2.4 3    2.4 3    2.5 8    2.5 8    2.5 8    2.5 8    2.5 8    2.5 8    2.5 8    2.5 8    2.6 5    2.6 5    2.6 5    2.6 5    2.6 5

desired output 

2.0 1     2.2 3     2.3 4    2.4 3   2.5 8    2.6 5

I am reading from a file and creating two lists, then sorting them after sorting I am trying to compare each elements number of occurances in a list but printing them with that number for example if a list is something like {1,2,3,3,3,5,5,5,6} then I want to print a report like 1 count =1 2 count =1 3 count = 3 5 count = 5 6 count =6.

this is what I have so far just one small thing I need to get it done.

def main():
    data = open("Iris.csv",'rU')
    petalWidths = []
    sepalWidths = []
    for line in data:
        line =  line.split(',')
        sepalWidths.append(line[1])
        petalWidths.append(line[3])
    sepalWidths.sort()
    checkForWidthCount(sepalWidths)
    petalWidths.sort()
    print sepalWidths

##        print petalWidths

def checkForWidthCount(mylist):


    for x in range(0,len(mylist)-1):
            count = 0
            for y in range (0,len(mylist)-1):

                    if mylist[x] == mylist[y]:
                            count+=1
                    else:
                            y+=count

            #x+=count                                
    print mylist[x],count

main()

Hey guys,

Hey guys,
Recently a friend of mine asked me to help her with her magazine website. I gave this website a look and figured out that it might be that tabs are not directing to the right URL or there are some files missing from the server. I have never worked on PHP before and therefore I have no clue whatsoever, where to start from? I need help

website is http://www.pakistanzindabad.pk
please help me

Any help would be appreciated thanks

Hi Guys does anyone here ever used apache Ivy. I need help here, I am a newbie in Ivy and trying to set up local repository and apache website is not useful at all.

Seems that p.getEmployees() is returning a List. You will have to iterate that list and than use the getName() method for each 'Employee' object in the list

Thanks man I got it :D

[code=java]for(Object object : result){
				Project p = (Project) object;
				System.out.print(p.getName()+" worked on by ");
				Iterator itr = p.getEmployees().iterator();
				if(!(itr.hasNext())){
					System.out.print("no employees.");
				}
				while(itr.hasNext()){
					Employee emp = (Employee) itr.next();
					System.out.print(emp.getName()); 
					if (itr.hasNext()){
						System.out.print(", ");
					}
				}
				System.out.println(); 
			}

[code=java]import java.util.*;
import java.util.Scanner;
import java.io.*;

public class ListList{

	public static void main(String [] args){

		LinkedList ll = new LinkedList();	
		Scanner in = new Scanner(System.in);
		int n = 0;
		while (!(n<0)){
			System.out.println("Enter a number: ");
			n = in.nextInt();

			ll.add(n);
		}
		System.out.println(ll);

	}
}

Try this and tell me if that is what you are trying to do.

List result = q.list();
		if (result.isEmpty()){
			System.out.println("No Projects");
		}
		else{
			for(Object object : result){
				Project p = (Project) object;
				System.out.println(p.getName()+" worked on by "+p.getEmployees().getName());
			}
		}

error :

System.out.println(p.getName()+" worked on by "+p.getEmployees().getName());

Can anyone help what is my stupid mistake here? And how can I deal with it?

/**

    public void displayCompaniesWithoutDepartments() {
        System.out.println("---- All Companies Without Departments ----");
		Session session = sessions.getCurrentSession();

Stupid me I was using wrong Query but it took me long to figure it out.

Hi everybody,

I'm trying to write a function that takes in 2 values, a min and a max, that prompts the user to enter a value within that range, and uses 0 as a sentinel to quit the loop.

My issue is, I also want the loop to continue prompting the user when the user enters nothing (i.e. hits enter) until a value between the range is entered. How do I go about doing this with the code I have already written? Thanks!

def getValidNum(min, max):
    QUESTION = "Enter a value, 0 to quit: "

    num = input(QUESTION)

    while num != 0:
        if num in range(min, max + 1):
            return num    
        else:
            print("Sorry %d - %d or 0 only") % min, max
            print("Try again.")
            num = input(QUESTION)

try using a Boolean variable and put it in condition of while when you want to break the loop say it false and when you think it should keep running say it true.
something like

flag = True
while num != 0 and flag

then you can also use flag to control your loop

I am having trouble figuring out how to read input from the keyboard and inserting that into a LinkedList. Any help or suggestions would be greatly appreciated.

import java.util.*;
import java.util.Scanner;
import java.io.*;

public class listlist{

        public static void main(String [] args){
                 
             LinkedList ll = new LinkedList();
             Scanner in = new Scanner(System.in);
             System.out.println("Enter a number: ");
             int n = in.nextInt();

             ll.add(n);

        }
}

I think your program is working fine it is adding number to the linked list if you want to add more than one number try using some sort of loop.
if you are trying to do something else let me know.

hi I am working on HQL queries and writing an application in Java it is just in development phase so I am using a dummy database.
But I am having troubles with displaying result using HQL queries.

/**
     * Displays a report listing all companies that have no departments.
     */
    public void displayCompaniesWithoutDepartments() {
        System.out.println("---- All Companies Without Departments ----");
        Session session = sessions.getCurrentSession();
        session.beginTransaction();
        Query q = session.createQuery("select comp.id , comp.name from Department as dept left outer join dept.Company as comp");
        List result = q.list();
        for (Object object : result){
            Company company = (Company) object;
            System.out.println(company.getName());

        }
        session.getTransaction().commit();
        // Finish this
    }

I know some part of my function is incorrect but at first the query is not running it self I have search on google It seems to be in the right order but I dont understand what is the problem.

I get this error

Error: could not resolve property: company_id of: Department

when department has many to one relation ship with Company.

int a = 4, b = 3;
String code = "a*b+a+2*b";
int result = unknown_function(code);
System.out.println(result);//expecting 22

Any ideas how to do that please?

if you can post ur full code it will help better.

Please if you could put your code here it will be really helpful for me to understand along with the errors messages thanks

I am considering your suggestion but I am going step by step first I am trying to learn how to handle arrays and how to handle the entries of array then I will surely go for Object Orientation.

i tried something similar in python it worked for me now its not working for me here is what i triend in python

def main():
    p=["12. My name is Furqan by Awesome Publisher"]
    name=p[0]
    i=0
    temp=""
    while (name[i]!="."):
        temp=temp+name[i]
        i+=1
    print temp
main()

it worked for me but is not working in java may be its different way to do it in java

public static int Rank(String line)
	{
        String [] ArrayEntry=new String[200];
		ArrayEntry[0]=line;
		int lineCounter=0;
		String tempRank="";

		while(!ArrayEntry[lineCounter].equals("."))
		{
			tempRank+=ArrayEntry[lineCounter];
			lineCounter++;
		}
		int rank = Integer.valueOf(tempRank).intValue();
		return rank;
	}

I am totally confused now its saying no error but not working

ok I admit its wrong because according to my problem it wont work for name and sports
it will become complicated but do comment on this method

public int Rank(array[counter])
	{
		String ArrayEntry=line[counter];
		int lineCounter=0;
		String tempRank="";

		while(!ArrayEntry[lineCounter].equals("."))
		{
			tempRank+=ArrayEntry[lineCounter];
			lineCounter++;
		}
		int rank = Integer.valueOf(tempRank).intValue();
		return rank;
	}

I tried this as a method to retrieve rank from the line but it is giving me bunch of errors
help me out i know it wont work without array but tell me if my syntax and logic is correct

First of all loop through the existing array like you are already doing and try to "extract" the 3 values from each element. Write separate methods for that.After you are successful you can create 3 arrays and put these inside with each loop:

String [] name = new String[i]; //remember the "i" ?
....
for(int counter=0;counter<i;counter++) {
 System.out.println(LineArray[counter]);
 
  name[i] = getName(LineArray[counter]);
 ...
}

The getName(LineArray[counter]); will take as argument the element of the array and return the name. You will have other methods for the "sport" and the "rank".

The best way is to create an object "Athlete" with attributes name, rank, sport and have a method that takes as argument the element of the array and return that object. Then you will put that in an array of "Athlete" objects. If you are not familiar with that leave for now

It certainly looks difficult to me but I can give it a try and if I had any problem I will post here ... by the ways thanks for helping so far I really appreciate what I am learning through you...

now can you help me determining how to split this array and save the ranking and name and sports in separate arrays.

well about the counter and for loop I was just checking if everything is going in the array or not I will remove it when my actual goal is achieved.

[code=java]package Test;
import java.io.*;
public class MainTest{

	public static void main(String[] args){

		String [] LineArray=new String[201];
		BufferedReader read = null;
		try
		{
			read = new BufferedReader(new FileReader("filename"));
			String lineRead=read.readLine();
            //lineRead=lineRead.split(".");
			int i=0;

			while (!(lineRead.equals(null)) && (i<LineArray.length))//lineRead !=null did not work
			{
				//System.out.println(lineRead);
				LineArray[i]=lineRead;
				i++;
				lineRead=read.readLine();
			}for(int counter=0;counter<LineArray.length;counter++)
				System.out.println(LineArray[counter]);
		}catch (IOException e)
		{
			System.out.println(e.getMessage());
		}finally
		{
			try
			{
				if (!(read.equals (null))) read.close();
			}catch (IOException e)
			{
				System.out.println(e.getMessage());
			}
		}
	}
}

here I fixed it now, now I have to break each entry in three parts ranking name and sports

Thank you very much sir I really appreciate your help but I was trying to play with it i know i made some mistake but I did not wanted to copy your code so I tried to write a similar one I am so confused I have a exam coming and professor said he will ask us to write a code to manipulate arrays selection sort and I dont know anything neither he taught anything I know what I did was stupid but I am learning and again really appreciate your help...

well I took your Idea and just doing an extra thing that it reads the line and add it to array now I cleaned up my code here it is

I have tried couple of things now I am dealing two types of error one is out of bounds and other one is its giving me only nulls.

BufferedReader reader = null;
try {
    reader = new BufferedReader(new FileReader("fileName"));
    String line = reader.readLine();
    while (line!=null) {
        System.out.println("The Line is: "+line);

        // do calculations with line

         line = reader.readLine();
    }
} catch (Exception e) {

} finally {
  if (reader!=null) reader.close();
}

If you are unfamiliar with using arrays, I would suggest to concentrate on that first, before going to write the code for reading from the file. Once you have understood the arrays very well, you may proceed.

I got this error when I tried the code
MainTest.java:31: unreported exception java.io.IOException; must be caught or declared to be thrown
read.close();

ok I will try.. thanks

I have never used arrays in Java, although I used them in Python but whatever u wrote up there i understand some of it because I have reading lots of blogs and online articles about java arrays.
and about the line problem my file is formatted in this way
1. JOHN CARTER in Sprint Race.

I am trying to figure out how to read a multi line txt file with a data like ranking, athlete name and Athletic sports name with two different year records like 2007 and 2008

like
1. JOHN CARTER in Sprint Race
19. JOHN CARTER in Sprint Race

I am trying to strip three things a part ranking in 2d array, 2d name array with first name and last name separated and event name.

lets say first 50 athletes ranking for 2007 and 2008 goes like this
1.
2.
3.
4.
.
.
.
.
50.
1.
2.
3.
4.
.
.
.
.
.50
I am totally lost I read couple of articles dealing with reading from from txt file articles and creating arrays but could not do extract anything fruitful.

here you go for odd and even values u can modify this code for largest and smallest.

[code=python]
Even=[]
Odd=[]
def IsEven(a):
    even=False
    while not even:
        calculate=a%2
        if calculate==0:
            even=True
        return even
    
def find_Even():
    for val in range (1,50):
        found_Even=IsEven(val)
        if found_Even==True:
            Even.append(val)
        else:
            Odd.append(val)

def output():
    print "\t\t\t  THE EVEN NUMBERS ARE\n"
    count=0
    while count<len(Even):
        print "%3i"%Even[count],"\t",
        count+=1
  
    print"\n"
    print "\t\t\t  THE ODD NUMBERS ARE\n"
    i=0
    while i<len(Odd):
        print "%3i"%Odd[i],"\t",
        i+=1
find_Even()
output()

oh well Thanks I got it actually I was calling wrong get method to read last point I needed to call
data.getlnDouble();
thanks

so any suggestions do I have to get all values as string and then change them as float or double???

[code=python]
import string
S = raw_input("Enter Sentence: ")
countSpace=string.count(S," ")
countTotal= len(S)
totalCharacter=countTotal-countSpace
print totalCharacter

you can also try this

i think this works fine and i tried it removing str before (m) and it worked to so i can say its good do you have any question?

your while loop is keep on going I give a value or not it keep on going but I am not sure what kind of help you are seeking can you explain ?

thanks man I am going to try that just tell me if I am on right track

back again
now I am creating the LineEquation class please help me out

[code=java]
public class LineEquation
{
    private double slope;
    private double x;
    private double y;
    private double x1;
    private double y1;
    
    public LineEquation(double slope,double x,double y,double x1,double y1){
            
        this.slope=slope;
        this.x=x;
        this.y=y;
        this.x1=x1;
        this.y1;
    
    }









} //End of class

here is my LineSegment class

public class LineSeg{

  // these are the attributes of a LineSeg object
    private Point end1;
    private Point end2;
    private double length;
    private double slope;
  

    // the constructor
    public LineSeg(double x1, double y1, double x2, double y2) {

        end1 = new Point(x1,y1);
        end2 = new Point(x2,y2);
        this.length = length;
        length=Math.sqrt((Math.pow(x2-x1,2))+(Math.pow(y2-y1,2)));
        
    }
    public double Slope(double x1, double y1, double x2, double y2){
        
        slope= (double)(y2-y1)/(x2-x1);
        
        return slope;
    
    }
    public double getLength(){
        
        return length;
    }
    
    //public double EquationLine(double slope,double x1,double y1,double x,double y){
    //}
    
}

you can also do like this:

a=0
b=0
c=0
d=0

if not(a==0 and b==0 and c==0 and d==0):
    print "go home"
else:
    print "come here"
