为何只显示一半????

[woshianiu]

我在ONEREASEBGBND函数中加载了一个位图,但总是只显示一半,这是为什么? CBitmap bitmap;
CDC dcMemory;
bitmap.LoadBitmap(IDR_BITMAP1);
dcMemory.CreateCompatibleDC(pDC);
dcMemory.SelectObject(&bitmap);
pDC->BitBlt(0,0,300,300,&dcMemory,0,0,SRCCOPY);
pDC->SetBkColor(pDC->GetBkColor());
return TRUE;

用GetBitmap函数取得位图的宽与高：
BITMAP bmpInfo; //Bitmap infomation
CDC dcMemory;
bitmap.LoadBitmap(IDR_BITMAP1);
bitmap.GetBitmap(&bmpInfo); //use GetBitmap() fill bmpInfo struct
dcMemory.CreateCompatibleDC(pDC);
dcMemory.SelectObject(&bitmap);
pDC->SetBkColor(pDC->GetBkColor());
pDC->BitBlt(0, 0, bmpInfo.bmWidth, bmpInfo.bmHeight, &dcMemory, 0, 0, SRCCOPY); //use bmpInfo
return TRUE;
