代碼如下：
pDC->BitBlt( ax*10, ay*10,bitmap.bmWidth,bitmap.bmHeight, &dcMemory,0,0,SRCCOPY);
Sleep(500);
pDC->BitBlt( ax*15, ay*10,bitmap.bmWidth,bitmap.bmHeight, &dcMemory,0,0,SRCCOPY);
dcMemory.SelectObject(hOldBitmap);
dcMemory.DeleteDC();
cbmp.DeleteObject();
就是想問一下怎么消除已經出現的第一張圖
uj5u.com熱心網友回復：
pDC->BitBlt( ax*10, ay*10,bitmap.bmWidth,bitmap.bmHeight, &dcMemory,0,0,SRCCOPY);倒了吧 ？應該
pDC->BitBlt(0,0,bitmap.bmWidth,bitmap.bmHeight, &dcMemory, ax*10, ay*10,SRCCOPY);
