C# と VB.NET の質問掲示板

開発環境：VS2008 .NETFramework3.5 言語：VB.NET

たとえばButton1を押した後にInternetExplorerを強制終了（タスクマネージャで言うプロセスの終了）をさせたいのですが
                    p = System.Diagnostics.Process.GetProcessById("IEXPLORE")
                    p.Kill()
とやっても終了しないどころか後のコードも実行されなくなってしまいます。
どのようにしたら強制終了出来るのでしょうか？ご指導よろしくお願いします。
