Question:
How can I get the handle of the Window containing a DOS box or
other console mode application?
Answer:
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 TForm1.Button1Click(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;
