Place a enhanced metafile on the clipboard (uses OLE)

Posted by Randy More on August 6th, 1998
(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 metafile copy of a view on the clipboard. It can be easily modified to work with any CWnd that draws to a CDC. 

void CMyView::OnEditCopyWmf() 
{ 
	tagSTGMEDIUM * data;
	CClientDC dcRef( this );
	data = new tagSTGMEDIUM;
	CMetaFileDC * dcMeta;
	dcMeta = new CMetaFileDC();
	COleDataSource* pData = new COleDataSource;
	CRect lmbr;
	GetClientRect(lmbr);
	//replace "ImageName" with a description of this image
	dcMeta->CreateEnhanced(&dcRef, NULL, NULL,"ImageName\0Copy\0\0" );
	dcMeta->SetMapMode(MM_TEXT);
	//actually draw to the device context
	OnDraw(dcMeta);
	//done drawing
	data->tymed = TYMED_ENHMF;
	data->hEnhMetaFile = dcMeta->CloseEnhanced();
	pData->CacheData( CF_ENHMETAFILE, data );
	pData->SetClipboard();
	delete dcMeta;
	delete data;
}

    Assume that these are the controls in a single dialog box.

    What i want is,on just pressing a button in toolbar,the data has to be sent to the clipboard ..Note that the nothing is selected or focussed.

    The data in the clipboard should be in the below format
    Name Vidya
    Age 23
    Sex Female
    occupation S/W Engineer


    How is it?

  • reading attributes like text height etc

    Thank you for your code, which is very useful. When I first tried it I had crash problems, because in my standard screen drawing routine I was reading attributes in order to draw text. The following modification seems to have sorted it.


    	dcMeta->SetAttribDC(dcRef.m_hAttribDC);

    	OnDraw(dcMeta);

    	//done drawing

    	dcMeta->ReleaseAttribDC(); // not sure if needed


    I hope this comment may be helpful.

  • Images do not render as expected when pasted to MS Word or MS PowerPoint

    Posted by Legacy on 12/09/2001 12:00am

         Thank you for the code sample.  I used it in a very simple test application.  Within that application, I draw a box and then write "Hello, World."  However, when I cut that image and paste it into an MS Powerpoint or an MS Word document, the results are not as drawn.  In both cases, the box is visible, but test is not.  Within MS Powerpoint, I can ungroup the image and recover the tst.  The rectangle is drawn as a series of lines and I used MM_TEXT mode to draw the image.


         Some questions:

         1.  Is there an agreed map mdoe that is used to cut and past objects?

         2.  Is it better to use TextOut or DrawText functions?

         3.  What can I do to correctly cut and paste images?


    The nest few lines contain the code I added:

    	dcMeta->SetMapMode(MM_TEXT);

    	//actually draw to the device context

    	dcMeta->MoveTo(0, 0);

    	dcMeta->LineTo(0, 20000);

    	dcMeta->LineTo(20000, 20000);

    	dcMeta->LineTo(20000, 0);

    	dcMeta->LineTo(0, 0);

    	dcMeta->TextOut(10000, 10000, "Hello, World.");

    	//done drawing

  • duplicating Alt+PrtScrn

    Thanks,

      Patrick
