· One min read

In MFC to fill the client area with a bitmap use the following code.

BOOL CMySDIView::OnEraseBkgnd(CDC\* pDC)
{
    CDC mymem;
    //Create a dc to represent display surface
    mymem.CreateCompatibleDC(pDC);

    CBitmap bmp;
    bmp.LoadBitmap(IDB\_MYBITMAP);
    mymem.SelectObject(&bmp);

    //BitBlt Copyes bitbamp from source (mymem) to destination (pDC)
    pDC->BitBlt(0,0,740, 520, &mymem,0,0, SRCCOPY);

    return TRUE; // CView::OnEraseBkgnd(pDC);
}
