Problem Creating Window

[Ady]

Hi,

When I create a window as follows

aWnd->hWnd = CreateWindowEx( WS_EX_CLIENTEDG E, strClassName, strWindowName,
dwStyle, 10, 10,
40,40,
hWndParent, NULL, aWnd->hInstance, NULL);

The window handle hWnd is null but when I call GetLastError the error code
is 0???????

Cany Someone Help?

Does the window get a WM_CREATE message? If so, how is it handled?

Hmm. If it returns 0, the window should be created while -1 cancels the
creation. If zero is what you are returning you may want to use the SPY tool
to see if some other message is doing you in.
