Hi,
I'm trying to write a dialog procedure, with a command button that closes the dialog. However, the dialog also has a Close window button on it, and clicking this doesn't close it at the moment.
When I positioned a breakpoint at my "switch (LOWORD(wParam)" statement and clicked the window button, wParam = 0x020003e8. Does the low word of this value equate to any constant listed in winuser.h?
