UI オートメーション要素の移動
Note
このドキュメントは、System.Windows.Automation 名前空間で定義されているマネージド UI オートメーション クラスを使用する .NET Framework 開発者を対象としています。 UI オートメーションの最新情報については、Windows Automation API の「UI オートメーション」を参照してください。
この例では、指定した画面位置に UI オートメーション要素を移動する方法を示しています。
例
次の例では、WindowPattern および TransformPattern コントロール パターンを使用して、プログラムで Win32 ターゲット アプリケーションを個別の画面位置に移動し、BoundingRectanglePropertyAutomationPropertyChangedEvent を追跡します。
