CRect rect;
GetClientRect(&rect);
CDC memDC;
CDC *pDC;
pDC = GetDC();
CBitmap bitmap;
CBitmap *pOldbitmap;
BITMAP hbitmap;
bitmap.LoadBitmap(IDB_BITMAP1);
memDC.CreateCompatibleDC(pDC);
pOldbitmap = memDC.SelectObject(&bitmap);
bitmap.GetBitmap(&hbitmap);
CSize size(hbitmap.bmWidth,hbitmap.bmHeight);
pDC->StretchBlt(0,0,rect.Width(),rect.Height(),&memDC,0,0,size.cx,size.cy,SRCCOPY);
memDC.SelectObject(pOldbitmap);
ReleaseDC(pDC);

HDC hdc;
HDC hdcmemory;
HBITMAP hbitmap,holdmap;
BITMAP bitmap;
RECT client;
PAINTSTRUCT ps;
GetClientRect(hWnd,&client);
hbitmap=LoadBitmap(hInst,(LPCTSTR)IDB_BITMAP1);//IDB_BITMAP1是位图资源名
hdcmemory=CreateCompatibleDC(NULL);
holdmap=(HBITMAP)::SelectObject(hdcmemory,hbitmap);
GetObject(hbitmap,sizeof(BITMAP),&bitmap);
hdc = BeginPaint(hWnd, &ps);
BitBlt(hdc,(client.right-client.left)/2,(client.bottom-client.top)/2,bitmap.bmWidth,bitmap.bmHeight,hdcmemory,0,0,SRCCOPY);
SelectObject(hdcmemory,holdmap);
DeleteDC(hdcmemory);
EndPaint(hWnd, &ps);

CBitmap* oldBitmap;
CBitmap newBitmap;

newBitmap.LoadBitmap("你的bitmap");

BITMAP bmpInfo;
newBitmap.GetBitmap(&bmpInfo);

CDC* dcMemory=new CDC;
CClientDC* dcm=new CClientDC(this);
dcMemory->CreateCompatibleDC(NULL);

oldBitmap= dcMemory->SelectObject(&newBitmap);

CRect rect;
GetClientRect(&rect);

int nX = rect.left + (rect.Width() - bmpInfo.bmWidth) / 2;
int nY = rect.top + (rect.Height() - bmpInfo.bmHeight) / 2;

dcm->StretchBlt(0, 0, rect.Width(), rect.Height(), dcMemory, 0,0,mWidth,bmpInfo.bmHeight, SRCCOPY);
dcm->SelectObject(oldBitmap);


ReleaseDC(dcm);
