为何在win2000下没有问题，而在win98下运行一会儿就出错。这是？？？？？？？？？
//从一张位图，句柄为m_hBitmap上剪切一块位图,并粘贴到相应的位置
void CXXXView::StretchAndStick(POINT BmpPoint)
{
CDC* pDC=GetDC();
HDC hdcSrc=::CreateCompatibleDC(pDC->GetSafeHdc());
HDC hdcDest=::CreateCompatibleDC(pDC->GetSafeHdc());
HBITMAP hbmpOld=(HBITMAP)SelectObject(hdcSrc, m_hBitmap);
HBITMAP hDestBmp = CreateCompatibleBitmap(pDC->GetSafeHdc(), 20, 20);
HBITMAP hOldDestBmp = (HBITMAP)SelectObject(hdcDest, hDestBmp);
//运行一会儿，就出现AfxMessageBox,出现必需的资源无法得到，这要如何
if (!StretchBlt(hdcDest, 0, 0, QiziWidth, QiziHeight, hdcSrc,
BmpPoint.x, BmpPoint.y, QiziWidth, QiziHeight, SRCCOPY))
AfxMessageBox("截取位图出错!");
BitBlt(pDC->GetSafeHdc(), BmpPoint.x, BmpPoint.y, QiziWidth, QiziHeight, hdcDest, 0, 0, SRCCOPY);
SelectObject(hdcSrc, hbmpOld);
SelectObject(hdcDest, hOldDestBmp);
DeleteDC(hdcSrc);
DeleteDC(hdcDest);
DeleteObject(hDestBmp);
ReleaseDC(pDC);
}

m_hBitmap和hDestBmp变量是怎么定义和赋值的

[eastrock]

HBITMAP m_hBitmap=LoadBitmap(AfxGetApp()->m_hInstance ,MAKEINTRESOURCE(IDB_BITMAP1));
是这样定义的和赋值的
