    curiousity about owned window

    I am wondering if it is improper to create an owned window using WS_POPUP. When I used this window style, the window would not show itself, however, when I changed it to WS_OVERLAPPED it worked just fine. Is WS_POPUP the incorrect style to use for an owned window, or should I be looking in my code for some other underlying problem?

    Thanks in advance

    Did you even try calling ShowWindow() on your WS_POPUP window?

    By 'owned' I assume you mean has the WS_CHILD style.

    WS_POPUP and WS_CHILD are mutually exclusive.

    If the overlapped window appeared, you would assume that the window has the WS_VISIBLE style or ShowWindow() was called.

    Sorry for the slow reply, I don't have internet access every day.

    Thanks, msdn was very helpful. I believe either I have some other flaw in my code or there is a bug in the compiler because all I do is swap out WS_POPUP and it works fine.

    I do not mean child when I write "owned." I am making a dialog box. I would also like to use this technique in other portions of my program to provide additional information to the user, so I thought I'd ask you all if I did something improper. I think I tried ShowWindow(), but when I get back to coding, I'll look.

    Does CreateWindow() return a valid HWND or NULL?

    If NULL what does GetLastError() return?

    Please post some code, the call to create the dlg and the dlg's WM_INITDIALOG handler.
