The following example demonstrates using the Windows API function FindWindow() to retrieve the handle of a console mode application. Note that the WndClass of a console window is different under Windows 95 and Window NT, and the title of the Window may contain a full path name under Windows NT.

Example:
procedure TForm .Button Click(Sender: TObject);
var
  info : TOSVersionInfo;
  ClassName : string;
  Title : string;
begin
 {See if we're running on Win95 or NT.}
  info.dwOSVersionInfoSize := sizeof(info);
  GetVersionEx(info);
  if (info.dwPlatformId = VER_PLATFORM_WIN32_NT) then begin
    ClassName := 'ConsoleWindowClass';
    Title := 'Command Prompt';
  end else begin
    ClassName := 'tty';
    Title := 'MS-DOS Prompt';
  end;
  ShowMessage(IntToStr(FindWindow(PChar(ClassName), PChar(Title))));
end;
