SelectObject(hdcBackGround,hbmOldBackGround); DeleteDC(hdcBackGround); SelectObject(hdcBackmap,hbmOldBackmap); DeleteDC(hdcBackmap); SelectObject(hdcWihtemap,hbmOldWihtemap); DeleteDC(hdcWihtemap); SelectObject(hdcBrick,hbmBrick); DeleteDC(hdcBrick); 类似这些不是都有返回值的嘛，你定义一个变量，把这些返回值看看，也许有帮助，还有 GetLasterror
