Unfortnately I was not able to convince her that black-backgrounded icons really *are* cool, and so this is my task now to find a solution how to change the icon's transparent area to a color of choice (preferrably white) *before* converting them to a bitmap.

Hi Frank,

No offense, but I think it is best if you address the question to ALL rather than directly to me (or one person only). The others might get lazy to help you!

Anyway, I'm not really fond with GDI+, I haven't play with it til today. So, I don't know much about it. So if it is okay for you to use GDI, then here is the step:

- Get the HICON (hLarge & hSmall) from your iconbuddy class.
- Use GetIconInfo() API to get the HBITMAP from each HICON. There are two HBITMAP on return, hBitmapColor and hBitmapMask.
- Copy the hBitmapColor to temporary DC (BitBlt using SRCCOPY)
- XOR the hBitmapMask to temporary DC (BitBlt using SRCPAINT / SRCINVERT)

After that you can read this article:
