I am working with CBitmaps (24 bpp).
If the loaded bitmap is not 24 bpp, so my app will crach.
I've searched how to convert 1 bpp, 4 bpp, 8 bpp & 16 bpp to 24 bpp, but unfortunatly no chance.

Help me please

How do you load the bitmaps? Anyway, have a look at CImage[^] class.

HANDLE WINAPI LoadImage(
  __in_opt  HINSTANCE hinst,
  __in      LPCTSTR lpszName,
  __in      UINT uType,
  __in      int cxDesired,
  __in      int cyDesired,
  __in      UINT fuLoad
);

Have you tried the CImage class? It should be easier.

I don't see any transformation functions in CImage class members. see: http://msdn.microsoft.com/en-US/library/5eb252d0.aspx

Solution 2

Are you sure LoadImage() is crashing? Have you checked the return type? Make sure that it's not returning NULL, if its not, then something else may be the problem.

No, LoadImage() is not crashing. My program is crashing when the loaded image is not 24 bpp. So I have to convert it to 24 bpp bitmap.

Well what's the error then when the application crashes? Look at the call stack and figure out which call is causing it.
