Place a bitmap image on the clipboard (uses OLE)

(1) If you don't have OLE in your project already then add this
#include <afxole.h>

and do the following during initialization
OleInitialize(NULL);

(2) The following places a bitmap copy of a view on the clipboard. It can be easily modified to work with any CWnd that draws to a CDC.

void CMyView::OnEditCopy() 
{ 
	
	COLORREF BACKGROUND_COLOR = RGB(255,255,255);
	tagSTGMEDIUM * data;
	CBitmap * junk;
	COleDataSource* pData = new COleDataSource;
	data = new tagSTGMEDIUM;
	junk = new CBitmap();
	CClientDC cdc(this);
	CDC dc;
	dc.CreateCompatibleDC(&cdc);
	CRect client;
	//replace this with something that calculates 
	//the proper rectangle size
	GetClientRect(client);
	junk->CreateCompatibleBitmap(&cdc,client.Width(),client.Height());
	dc.SelectObject(junk);
	CBrush fill(BACKGROUND_COLOR);
	dc.FillRect(client,&fill);
	//replace this with something that draws to a CDC
	OnDraw(&dc);
	data->tymed = TYMED_GDI;
	data->hBitmap = HBITMAP(*junk);
	pData->CacheData( CF_BITMAP, data );
	pData->SetClipboard();
	delete data;
	delete junk;
	
}

  • Bug fix for Access violation

When this functions is called second time you can see a "first chance exception -Access violation" warning in the debug window, This also causes crash in the release version. Here is the fix for the problem.

    COLORREF BACKGROUND_COLOR = RGB(255,255,255);
    tagSTGMEDIUM * data;
    FORMATETC fe = {
    CF_BITMAP,NULL,DVASPECT_CONTENT,-1,TYMED_GDI
    };
    CBitmap * junk;
    COleDataSource* pData = new COleDataSource;
    data = new tagSTGMEDIUM;
    junk = new CBitmap();
    CClientDC cdc(this);
    CDC dc;
    dc.CreateCompatibleDC(&cdc);
    CRect client;
    //replace this with something that calculates
    //the proper rectangle size
    GetClientRect(client);
    junk->DeleteObject();
    junk->CreateCompatibleBitmap(&cdc,client.Width(),client.Height());
    CBitmap* pOld = dc.SelectObject(junk);
    CBrush fill(BACKGROUND_COLOR);
    dc.FillRect(client,&fill);

    //replace this with something that draws to a CDC
    OnDraw(&dc);
    dc.SelectObject(pOld);

    fe.cfFormat = CF_BITMAP;
    fe.ptd = NULL;
    fe.dwAspect = DVASPECT_CONTENT;
    fe.lindex = -1;
    fe.tymed = TYMED_GDI;
    data->tymed = TYMED_GDI;
    data->hBitmap = (HBITMAP)junk->m_hObject;// HBITMAP(*junk);
    data->pUnkForRelease = NULL;
    pData->CacheData( CF_BITMAP, data, &fe);
    pData->SetClipboard();
    delete data;
    delete junk;

    you MUST remove "delete junk;" from above codes
    or the owner of clipboard can NOT get bitmap from it
