There is no way :(

Can suggest you manually convert it to icon and use SetIcon with hIcon parameter:

 

 CImageList il;
 il.Create(bmp.bmWidth, bmp.bmHeight, ILC_COLOR24 | ILC_MASK, 0, 1);
 il.Add(CBitmap::FromHandle(m_hBitmap), crTransparent);

 ASSERT(il.GetImageCount() == 1);

 il.ExtractIcon(0);

Is there a way to specify the transparency color of a bitmap for an icon specified for a CXTButton?

I've noticed that the color is determined by the color at pixel point 0,0 - maybe this is wrong but...
