Title: CreateWindowEx problem
|
Thanks,
this was found to be (as you suggested) a failure in the
WM_CREATE handler. There was a problem with a bitmap that was causing the
create to return (-1) instead of 0.
-Jean
Then another engineer made some changes to it,
and the new version exhibits a strange problem. When the list view is
created using ::CreateWindowEx, the function call returns a NULL hWnd.
However, a GetLastError call returns an error of 0 (no error)! The
NULL hWnd causes an assertion at application startup.
Two things come to my mind:
1. Make sure the window class you're passing to
CreateWindowEx( ) is properly registered.
2. Make sure you're not blowing anything in the
WM_CREATE message handler.
Good
luck,
Ehsan
