プロセス名の書式指定は文字列にします。親コンポーネント型があれば、この型と組み合わせます。
Overrides Public Function ToString() As String
[C#]
public override string ToString();
[C++]
public: String* ToString();
[JScript]
public override function ToString() : String;
戻り値
ベース コンポーネントの ToString の戻り値と組み合わせた ProcessName 。
使用例
[Visual Basic, C#, C++] メモ帳のインスタンスを起動する例を次に示します。この例では、インスタンスの起動後、関連付けられているプロセスのさまざまなプロパティが取得および表示されます。その後、プロセスの終了を検知し、プロセスの終了コードを表示します。
