What are you trying to do here?

The CBitmap::LoadBitmap function is used to load an image into the bitmap, not set an image into a picture control...

it's not as easy as i thought

CStatic *picture = (CStatic*) GetDlgItem(IDC_STATIC_PICTURE);
picture->SetBitmap(hBitmap);

RGBQUAD *pColors = pbmi->bmiColors;
