converting this code tot non-mfc
-
i tried to convert the code showed in this article (http://www.codeproject.com/bitmap/screencapture.asp) to non-mfc Standard Win32 code, with a bit of WTL. I came up with this: void CMainDlg::CopyWndToClipboard(HWND pWnd ) { CBitmap bitmap; CClientDC dc(pWnd); HDC memDC; RECT rect; memDC = ::CreateCompatibleDC(dc.m_hDC); ::GetWindowRect(pWnd,&rect); bitmap.CreateCompatibleBitmap(dc.m_hDC, rect.right-rect.left,rect.top-rect.bottom ); CBitmap* pOldBitmap= (CBitmap*)(HBITMAP)::SelectObject(memDC,&bitmap); ::BitBlt(memDC,0, 0, rect.right-rect.left,rect.top-rect.bottom, dc.m_hDC, 0, 0, SRCCOPY); ::OpenClipboard(::GetParent(pWnd)) ; EmptyClipboard() ; SetClipboardData (CF_BITMAP, (HBITMAP)bitmap ) ; CloseClipboard () ; SelectObject(memDC,pOldBitmap); bitmap.Detach(); } Which doesn't seem to work. All is does is throw some rubbish on the clipboard. Does somebody know a function to replace my code or does somebody know what i'm doing wrong? Thanks :-)
