Hi cesar,

I use this code for capture screen to jpg file:

    HDC dc = GetDC(0);
    Graphics::TCanvas *ScreenCanvas = new Graphics::TCanvas;
    ScreenCanvas->Handle = dc;
    Image1->Picture->Bitmap->Width = Screen->Width;
    Image1->Picture->Bitmap->Height= Screen->Height;
    TRect rect = Rect(0,0,Screen->Width, Screen->Height);
    Image1->Picture->Bitmap->Canvas->CopyRect(rect, ScreenCanvas, rect);
    delete ScreenCanvas;
    ReleaseDC(NULL,dc);

  AnsiString datehour = FormatDateTime("yyyymmdd-hhnnss",Now());

    TJPEGImage *jp = new TJPEGImage();
    try {
        jp->Assign(Image1->Picture->Bitmap);
        jp->CompressionQuality=StrToInt(50);
        jp->SaveToFile(datehour+".jpg");
    }
  __finally
  {
    delete jp;
  }
