请教，我想在视图区中显示一个位图，为什么这样什么都不现实呢？（源码在里面）

[wgch007]

void CThunder1View::OnDraw(CDC* pDC)
{
CThunder1Doc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here

CBitmap bmp;
if (bmp.LoadBitmap(IDI_ICON1))
{

// Get the size of the bitmap
BITMAP bmpInfo;
bmp.GetBitmap(&bmpInfo);

// Create an in-memory DC compatible with the
// display DC we're using to paint
CDC dcMemory;
dcMemory.CreateCompatibleDC(pDC);

// Select the bitmap into the in-memory DC
CBitmap* pOldBitmap = dcMemory.SelectObject(&bmp);

// Find a centerpoint for the bitmap in the client area
CRect rect;
GetClientRect(&rect);
int nX = rect.left + (rect.Width() - bmpInfo.bmWidth) / 2;
int nY = rect.top + (rect.Height() - bmpInfo.bmHeight) / 2;

// Copy the bits from the in-memory DC into the on-
// screen DC to actually do the painting. Use the centerpoint
// we computed for the target offset.
pDC->BitBlt(nX, nY, bmpInfo.bmWidth, bmpInfo.bmHeight, &dcMemory,
0, 0, SRCPAINT );

dcMemory.SelectObject(pOldBitmap);
}
else
TRACE0("ERROR: Where's IDB_BITMAP1?\n");


}

放在OnEraseBkgnd或OnPaint里试一下,还有看一看图是不是真的已经载入了

[wgch007]

如何判断位图是否真的载入了？

下面的语句一定可以用，我已经用了的
CDrawScrollBmpView::CDrawScrollBmpView()
{
// TODO: add construction code here
HBITMAP hBmp=(HBITMAP)::LoadImage(AfxGetInstanceHandle(),"C:\\My Documents\\image2.bmp",
IMAGE_BITMAP,0,0,
LR_CREATEDIBSECTION|LR_LOADFROMFILE);
m_picture.Attach(hBmp);
}

void CDrawScrollBmpView::OnDraw(CDC* pDC)
{
CDrawScrollBmpDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here

CDC dc;
dc.CreateCompatibleDC(pDC);
dc.SelectObject (&m_picture);
BITMAP bmp;
m_picture.GetBitmap (&bmp);
pDC->BitBlt(300,0,bmp.bmWidth ,bmp.bmHeight,&dc,0,0,SRCCOPY);

}
