Re: Bitmap in CStatic is not redrawn

Well, I'm embarrassed to report that I discovered the problem: passing a NULL HBITMAP to the static control before DlgResize_Init() was called. My guess is that the initial size of the control was 0 x 0, as it had no picture contained, and that was the size saved by CDialogResize, and subsequently used after it finished laying out the dialog.

If it is found, I use GDI+ to scale the image down nicely, saving the resulting Gdiplus::Bitmap* to a member variable (read: keeping it in scope). Then, I call GetHBITMAP(), and pass that to CStatic::SetBitmap(). The image shows up on the main dialog, and life is good...until it needs to be redrawn. Then, it just disappears completely. I tried adding the redraw flag to my CDialogResize map, but it didn't seem to fix it.
