Как использовать консоль в не-консольном приложении?

Code:

{

 For implementing console input/output for non-console applications you

should use the AllocConsole and FreeConsole functions.

The AllocConsole function allocates a new console for the calling process.

The FreeConsole function detaches the calling process from its console.

Example below demonstrates using these functions:

 }

procedure TForm1.Button1Click(Sender: TObject);

var

  s: string;

begin

  AllocConsole;

  try

    // Change color attributes

   SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),

                                         FOREGROUND_BLUE OR FOREGROUND_GREEN or

                                         BACKGROUND_RED );

    Write('Type here your words and press ENTER: ');

    Readln(s);

    ShowMessage(Format('You typed: "%s"', [s]));

  finally

    FreeConsole;

  end;

end;
