MagSetWindowFilterList function not remove specified window of screenshot

[flashcoder]

@Zacherl,

thank you very much, your suggestion about MagSetWindowFilterList worked fine.
I will try translate the part of save content of hwndmag to a image format.

I tried the suggestion of @Fukiszo but not worked see:

Delphi-Quellcode:

Canvas := TCanvas.Create;
  MyBitmap := TBitmap.Create;
  DC := GetWindowDC(hwndMag);

  GetWindowRect(hwndMag, r);

  try
    Canvas.Handle := DC;

      MyBitmap.Width := r.Width;
      MyBitmap.Height := r.Height;

      MyBitmap.Canvas.CopyRect(Rect(0, 0, MyBitmap.Width, MyBitmap.Height), Canvas,
                               Rect(0, 0, r.Width, r.Height));

      MyBitmap.SaveToFile('c:\screen.bmp');

  finally
    ReleaseDC(0, DC);
    MyBitmap.Free;
    Canvas.Free
  end;

But if someone know a way in Delphi and that works, i will accept.
