Hi,
I can set the HBITMAP of a static control perfectly. But when I try to get
the HBITMAP, I always get 0.
// this works, I can see it
HBITMAP copyxp = SendMessageA((HWND)pW, STM_SETIMAGE, (WPARAM)0,
(LPARAM)(*pBmp));
// this will return 0. I call it right after the STM_SETIMAGE.
HBITMAP hGetImg = SendMessageA((HWND)pW, STM_GETIMAGE, (WPARAM)0,
(LPARAM)0);
..
if(copyxp) DeleteObject(copyxp);
