IFeatureSupport.GetVersionPresent メソッド
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim instance As IFeatureSupport Dim feature As Object Dim returnValue As Version returnValue = instance.GetVersionPresent(feature)
戻り値
指定した機能のバージョン番号を表す Version。その機能がインストールされていない場合は null 参照 (Visual Basic では Nothing)。


IFeatureSupport の OSFeature 実装を使用し、LayeredWindows 機能の有無を問い合わせる例を次に示します。機能が存在するかどうかを確認するには、バージョンが null 参照 (Visual Basic では Nothing) かどうかを調べます。結果はテキスト ボックスに表示されます。このコードは、textBox1 が作成され、フォーム上に配置されていることを前提にしています。
