This seems fine to me. Anyone have a comment or can I add it?

Until this issue is clarified I suggest a fallback to BitBlt:

success = AlphaBlend(hDC,
                              x, y, (rectFrom.right - rectFrom.left), h,
                              sourceDC,
                              rectFrom.left, rectFrom.top,
                              (rectFrom.right - rectFrom.left), h,  
blendFunc);
if(success)
         break;
