    problem closing a window

    I have a program with two windows. I open the second window by pressing a button. And close it using the DestroyWindow( ), I also tried PostQuitMessage(WM_QUIT ). Both of these functions result in the program crashing. When I click on the X in the top right of the window or press alt+F4 the window closes perfectly and returns to the first window.

    Q. What signal is alt+F4 sending to the window.



    p.s I am using VC++
    When i find myself in times of trouble. mother mary comes to me, speaking words of wisdom, let it be C

    A. WM_SYSCOMMAND.

    For future reference you should direct your windows questions to the windows board.
