Hi Andrian,

This code copies entire screen to clipboard:

/***********/
// copy desktop window's content to a CBitmap
CWnd* pWnd = GetDesktopWindow();
CRect rect;
pWnd->GetWindowRect( rect );
CDC* pDC = pWnd->GetDC();
CDC memDC;
memDC.CreateCompatibleDC( pDC );
CBitmap bmp;
bmp.CreateCompatibleBitmap( pDC, rect.Width(), rect.Height() );
CBitmap* pOldBmp = memDC.SelectObject( &bmp );
memDC.BitBlt( 0, 0, rect.Width(), rect.Height(), pDC, 0, 0, SRCCOPY );
memDC.SelectObject( pOldBmp );
memDC.DeleteDC();
// copy bitmap to clipboard
OpenClipboard();
EmptyClipboard();
SetClipboardData( CF_BITMAP, (HBITMAP)bmp);//Detach() );
CloseClipboard();
/***********/

BTW, olgat, this site describes printing for 16bit DOS app's ...

hope that helps,

ZOPPO

I'm not sure ... given code works on my system (WinNT4) ... perhaps try it without the clipboard stuff, just bitblt the memory dc's content to a window...
