It looks big, but remove the comments and you have a mere 12 lines of code. cleanup by reselecting the old bitmap object into the DC TmpList.DrawIndirect (&dcMem, 0, CPoint ( 0, 0),ĬSize (rect.Width (), rect.Height ()), CPoint ( 0, 0)) This call apparently "draws" the bitmap from the list, // onto the new destination bitmap Select the new destination bitmap into the DC we created aboveĬBitmap* pBmpOld = dcMem.SelectObject (destBitmap) Using the bitmap passed in, Create a bitmap // compatible with the window DC // We also know that the bitmap needs to be a certain size.ĭestBitmap->CreateCompatibleBitmap (this->GetWindowDC(), This rect simply stored the size of the image we need Heres where it gets fun // Create a Compatible Device Context using // the valid DC of your calling windowĬDC dcMem dcMem.CreateCompatibleDC (GetWindowDC()) Now we need to get som information about the image Then swap the requested image to the first spot in the list First we want to create a temporary image list we can manipulate Void CMyWindowClass::GetImageFromList(CImageList *lstImages, It then draws the requested image into the destination bitmap.
