InstallEventArgs.SavedState プロパティ
インストールの現在の状態を表す IDictionary を取得します。
Public ReadOnly Property SavedState As IDictionary
[C#]
public IDictionary SavedState {get;}
[C++]
public: __property IDictionary* get_SavedState();
[JScript]
public function get SavedState() : IDictionary;
プロパティ値
インストールの現在の状態を表す IDictionary 。
使用例
[Visual Basic, C#, C++] InstallEventArgs クラスの InstallEventArgs コンストラクタおよび SavedState プロパティの例を次に示します。
[Visual Basic, C#, C++] BeforeCommit
および AfterCommit
という 2 つの新しいイベントがあります。これらのイベントのハンドラは、それぞれ OnBeforeCommit
および OnAfterCommit
という名前のプロテクト メソッドから呼び出されます。これらのイベントは、 Commit メソッドが呼び出されたときに発生します。
