To open a form see Show() and ShowDialog() methods of class Form.

Yah sir,
i trying with tat...
I created one new form from new item and named it image.
In main form,
I did the following,
#include "image.h"
Then, i double clicked the button, and included the following event,

image ^ f2 = gcnew image;
f2->Show();

But i,m getting the following error,

How to clear this?

[sudhavelvizhi]

To this now i included,

#include "windows.h"
Now the error has reduced to 2.
The errors are,
c:\project\project\Form1.h(129) : error C2039: 'GetEnvironmentVariableW' : is not a member of 'System::Environment'
1> c:\windows\microsoft.net\framework\v2.0.50727\mscorlib.dll : see declaration of 'System::Environment'
1>c:\project\project\Form1.h(129) : error C2660: 'GetEnvironmentVariableW' : function does not take 1 arguments

[sudhavelvizhi]

Again from code guru i got that i hav to include
#pragma once
#using <mscorlib.dll>
#undef GetEnvironmentVariable
#include <windows.h>
//#include <atlstr.h>
#include "image.h"

Again the error exixts.... Y? How to clear this?

[sudhavelvizhi]

Just i placed <windows.h> above, i got resolved of it.
Y it is so?

Hi sunny
Sorry, i could not open this page,

VC++ Example: Listbox In-place Editing, CListBox, Text Input,

Can u me some other suggestions

[sudhavelvizhi]

Now i one more doubt..
Is it possible to edit a text file in listbox and save the file again?

[cilu]

Edit in list box? No. Why would you open a file in a list box. I don't see how that would work. Display it in a text box.
