Screen Capture to the Clipboard

How do you capture the bitmap of a window? This little download shows how, and places the bitmap on the clipboard.


One of the common questions that I find on the microsoft.public forums is "How do I get a bitmap of a window on the screen?" Well, here's a little subroutine I used extensively in writing Win32 Programming, because I realized that for the number of illustrations I wanted for the book, there was no hope of doing screen captures and then hand-editing just the control I wanted to show. So all my Explorers have a little button somewhere that performs a screen capture of the example window and drops it into the clipboard. I could then paste it into the document, or paste it into an editor and save it as a TIFF or JPEG as well.


void toClipboard(CWnd * wnd, BOOL FullWnd);


#include "stdafx.h"
#include "toclip.h" 
*                                 toClipboard
* Inputs:
*       CWnd * wnd: Window whose contents are to be sent 
*                   to the clipboard
*       BOOL FullWnd: TRUE for entire window, 
*                     FALSE for client area
* Result: void
* Effect: 
*       Copies the contents of the client area or the window
*       to the clipboard in CF_BITMAP format.

void toClipboard(CWnd * wnd, BOOL FullWnd)
     CDC dc;
        { /* full window */
         HDC hdc = ::GetWindowDC(wnd->m_hWnd);
        } /* full window */
        { /* client area only */
         HDC hdc = ::GetDC(wnd->m_hWnd);
        } /* client area only */

     CDC memDC;

     CBitmap bm;
     CRect r;

     CString s;
     CSize sz(r.Width(), r.Height());
     CBitmap * oldbm = memDC.SelectObject(&bm);
     memDC.BitBlt(0, 0,,, &dc, 0, 0, SRCCOPY);

     ::SetClipboardData(CF_BITMAP, bm.m_hObject);

     bm.Detach();  // make sure bitmap not deleted with CBitmap object
