Question on ENTER key

Hi there,
         I've got a problem whenever I run my visual c++ program, the main window popped up but whenever I pressed the ENTER key, it'll destroy itself. Is there any way to capture the ENTER key and stop the window from destroying itself when the ENTER key is pressed? For ur info. I'm using MSVC 5.0 and my program is dialog-based and I'm working on a win98 platform.

Any help offered will be very much appreciated!

Capture your OnOK button message. And don't call the base class's OnOK function. This is the one which is making your app to close down
e.g. for dialog box

CMyDialog::OnOK ()
{
   CDialog::OnOK ();
}

The above code will make the app to close. Instead you wanna to have

CMyDialog::OnOK ()
{
}

If i don't call the OnOK(); function... if there's a mouse click on the "Done" button... the window will not destroy itself... is there another other ways?

You won't see OnOK () function call. You will have to override this call. And this will be the simplest solution to your problem.

I think I've overwritten it because the window won't destroy itself after I pressed the ENTER key but however.. when I clicked on the "Done" button... the program still cannot terminate... Is there any ways to terminate it when "Done" button is clicked?

Alrite! Finally...

Call
 ::PostQuitMessage (int code) API function at the end of your Done () function. And code can be any integer you like. It simply represent the exit code.

I hope this will solve your problem.
