VC++ MFC Example: Clipboard on CF_DIB, CF_METAFILEPICT, OpenClipboard, GetClipboardData, CloseClipboard

Introduction

If you want to display a bitmap from the clipboard which is in the CF_DIB format in one of my applications. Also, all the other clipboard articles here had code to write CF_DIB to the clipboard, but not read it. So the following codes will be very useful.

// pDC is the DC to draw to
// metafile is a CRect to display the DIB/Metafile in
    CRect    metafile(0, 0, 100, 100);    // example location
    if (IsClipboardFormatAvailable(CF_METAFILEPICT))
    {
        // play a metafile from the clipboard if available
        GLOBALHANDLE    hGMem ;
        LPMETAFILEPICT    lpMFP ;
        OpenClipboard() ;
        hGMem = GetClipboardData(CF_METAFILEPICT) ;
        lpMFP = (LPMETAFILEPICT)GlobalLock(hGMem) ;
        pDC->SaveDC() ;
        pDC->SetMapMode(lpMFP->mm) ;
        pDC->SetViewportExt(metafile.Width(), metafile.Height()) ;
        pDC->SetViewportOrg(metafile.left, metafile.top) ;
        pDC->PlayMetaFile(lpMFP->hMF) ;
        VERIFY(pDC->RestoreDC(-1)) ;
        GlobalUnlock(hGMem) ;
        CloseClipboard() ;
    }
    if (IsClipboardFormatAvailable(CF_DIB))
    {
        // a DIB is in the clipboard, draw it out
        GLOBALHANDLE    hGMem ;
        LPBITMAPINFO    lpBI ;
        void*            pDIBBits;
    
        OpenClipboard() ;
        hGMem = GetClipboardData(CF_DIB) ;
        lpBI = (LPBITMAPINFO)GlobalLock(hGMem) ;
        // point to DIB bits after BITMAPINFO object
        pDIBBits = (void*)(lpBI + 1); 
        ::StretchDIBits(pDC->m_hDC,
            metafile.left, metafile.top, 
            metafile.Width(), metafile.Height(),
            0, 0, lpBI->bmiHeader.biWidth, 
            lpBI->bmiHeader.biHeight,
            pDIBBits, lpBI, DIB_RGB_COLORS, SRCCOPY);
        GlobalUnlock(hGMem) ;
        CloseClipboard() ;
    }
