Hello, a have a question about borland c++/c 3.1.
I running win3.1 under dos5.0. I own borland c/c++ 3.1.

WHen I compile and execute the following code the windows just vanishes
away before I can cause an event to happen to exit WaitMessage function
call. Also, the text part of the button on the window is blank.

Basically, the program is terminating before anythings happends and all the the defined window get is a captions and a outline of  aa button.

Why ?, I copied this program out of a book. does anyone know why it won't run.
actual code followins.

*All code is small*

  {

  10, 10, 100, 100, NULL, NULL, hInstance, NULL ) ;
  ShowWindow( hWnd, nCmdShow ) ;
  WaitMessage();
  return 0;
