Prozess beenden von Task-Manager mit VB 6 Code

Gibt es zwei Möglichkeiten:
1. Senden von WM_CLOSE an die Ziel-Anwendung, wenn es hat ein Fenster (versteckt/sichtbar). Task-Manager "Task Beenden" wird diese Methode verwendet. Die meisten Anwendungen handle, WM_CLOSE, und kündigen würde.
2. Verwenden TerminateProcess APi zu töten, gewaltsam - Task-Manager "Prozess Beenden" wird diese Methode verwendet. Diese API gewaltsam tötet den Prozess.

Ein Beispiel finden Sie hier:
