ContainerControl コンストラクタ

ContainerControl クラスの新しいインスタンスを初期化します。

Public Sub New()
[C#]
public ContainerControl();
[C++]
public: ContainerControl();
[JScript]
public function ContainerControl();

使用例

[Visual Basic, C#, C++] ScrollableControl クラスから継承し、 IContainerControl インターフェイスを実装する例を次に示します。実装は、 ActiveControl プロパティおよび ActivateControl メソッドに追加されます。
