HOWTO: Problem with DLGWINDOWEXTRA Definition in Winuser.h File
The information in this article applies to:
- Microsoft Windows CE Operating System versions 2.11, 2.12, 3.0
The include file, Winuser.h, for Windows CE defines DLGWINDOWEXTRA to be 32. When you create a custom dialog box window class, by using the value that is provided for DLGWINDOWEXTRA, a variety of problems occur, presumably because the number of extra window bytes provided (32) isn't sufficient.
Instead, Microsoft recommends that you use the GetClassInfo function, which actually returns a value of 36 for the dialog box window class.
