windows form application

thanks very much ***** thanks very much ***** thanks very much ***** thanks very much ***** i think your code is for c# i need for cpp windows form application but i have got an some clue from your code which solve my problem and my code is as follow String^ s1 ; array ^s2; StreamReader^ reader = gcnew StreamReader(openFileDialog1->FileName); while(!reader->EndOfStream) {s1 = reader->ReadLine(); s2 = s1->Split(nullptr); for(int i=0;iLength;i++) textBox1->AppendText(s2[i]+" "); }

I am still not sure what you need but I hope the following is close enough. This will process the third column of each record. It is a Console program but the code can be used in a form application also. You can use the console program to test the code if that is convenient.

#include "stdafx.h"

using namespace System;
using namespace System::IO;
using namespace System::Collections::Generic;

int main(array ^args)
{

int i;
String^ s;
array^ sa;
StreamReader^ sr;
try { sr = gcnew StreamReader(L"Data.txt"); }
catch (Exception^ ex)
{

Console::WriteLine(L"Open error: {0}", ex);
return 0;

}
while (!sr->EndOfStream)
{

s = sr->ReadLine();
sa = s->Split(nullptr);
if (sa->Length >= 3)
{

if (Int32::TryParse(sa[2], i))

Console::WriteLine(i);

else

Console::WriteLine("Error from: {0}", sa[2]);

}

}
return 0;

}

I am sorry for that sam

my data is as per following

xyz data
3 2 4 3 2
Sr. No.  name    x1   x2    x3 ....
1           abc      13   42    53....
2           xaz       42  32    43....
and so on
now from this data i have to read column viz. 13, 42 etc
also i have to read specific no like 3 and 4 from second line
i use visual studio 2005 cpp windows form application

I have an answer for you but please be more specific about the format of the data. Is the integer the first number on the line? Is there nothing else, such as spaces, before the number? Is there always a space or an end-of-line after the integer?

It is very frustrating for me when I answer a question and then the person says my answer is wrong and then the person I am trying to help tells me something they should have told me originally. If I post sample code that does what I understand you need, then please don't tell me it is wrong if there is something you did not tell me about what you need.
