i have tied to a rectangle in caption bar of window but this doesn't work .am i doing any mistake.plz correct me . Code: void CMainWnd::OnNcPaint( ) { CDC dc = (CDC)GetWindowDC(); RECT rectMine = {30,3,100,20}; FillRect(dc, &rectMine, (HBRUSH)GetStockObject(DKGRAY_BRUSH)); SetBkMode(dc, TRANSPARENT); SetTextColor(dc, RGB(255, 0,0)); DrawText(dc, "My Dialog", strlen("My Dialog"), &rectMine, 0); ReleaseDC(dc); }
Your mixing the CDC class with HDC handles and that won't work by forcing casts. Try replacing your first line with: Code: HDC dc = GetWindowDC()->m_hDC; and your last line with this: Code: ::ReleaseDC(m_hWnd,dc);
