      ScreenDC: HDC;
      ScreenHandle: HWnd;
      ScreenBitmap: TBitmap;
      Jpg:TJpegImage;
      filename:string;
      time:string;
    begin
      ScreenHandle := GetDeskTopWindow;
      ScreenDC := GetDC(ScreenHandle);
      time:=DateTimeToStr(Now);
      time:=StringReplace(time, ':', '-', [rfReplaceAll, rfIgnoreCase]);
      time:=StringReplace(time, '/', '-', [rfReplaceAll, rfIgnoreCase]);
     

      GetWindowText(GetForegroundWindow, Wnd2, SizeOf(Wnd2));






      filename:=extractfilepath(paramstr(0))+'\'+wnd2+' - '+time+'.jpg';
      try
        ScreenBitmap := TBitMap.Create;
        try
          ScreenBitmap.Width := Screen.Width;
          ScreenBitmap.Height := Screen.Height;
          BitBlt(ScreenBitmap.Canvas.Handle, 0, 0,
              Screen.Width, Screen.Height, ScreenDC, 0, 0, SRCCOPY);
             // Clipboard.Assign(ScreenBitmap)
             try
               jpg:=TJpegImage.Create;
               jpg.PixelFormat := jf24bit;
               Jpg.CompressionQuality:=70;
               Jpg.ProgressiveEncoding:=True;
               // Jpg.Grayscale:=
               Jpg.Assign(ScreenBitmap);
               Jpg.SaveToFile(FileName);
             finally

             end;
        finally
          ScreenBitmap.Free
        end
      finally
        ReleaseDC(ScreenHandle, ScreenDC)
      end
    end {ScreenShot};
