How do I handle multiple bitmaps in memory?

[Iceman]

I'm trying to take multiple small bitmaps, BitBlt them into a memory dc then using a mask, draw them transparently to the screen. With one bitmap from a file it works fine, but when I combine them to an in memory DC and do the transparent blt, the colors get screwed up.

try to use TransparentBlt(), it uses chroma key to apply the transparency, and much easier

BOOL TransparentBlt(
  HDC hdcDest,        // handle to destination DC
  int nXOriginDest,   // x-coord of destination upper-left corner
  int nYOriginDest,   // y-coord of destination upper-left corner
  int nWidthDest,     // width of destination rectangle
  int hHeightDest,    // height of destination rectangle
  HDC hdcSrc,         // handle to source DC
  int nXOriginSrc,    // x-coord of source upper-left corner
  int nYOriginSrc,    // y-coord of source upper-left corner
  int nWidthSrc,      // width of source rectangle
  int nHeightSrc,     // height of source rectangle
  UINT crTransparent  // color to make transparent
);
