 メンバ名説明
AssociateIndexヘルプ ファイルが開き、指定されたトピックの最初の文字のインデックス エントリが表示されます。 
Findヘルプ ファイルの検索ページが表示されます。 
Indexヘルプ ファイルのインデックスが表示されます。 
KeywordIndexヘルプ ファイルが開き、指定されたインデックス エントリを持つトピックが存在する場合、そのトピックが表示されます。そのトピックが存在しない場合、指定されたキーワードに最も近いインデックス エントリが表示されます。 
TableOfContentsヘルプ ファイルの目次が表示されます。 
Topic指定されたトピックがヘルプ ファイルに存在する場合、そのトピックが表示されます。 
TopicIdヘルプ ファイルが開き、トピックの数値識別子で指定されたトピックが表示されます。 
解説解説

この列挙体は、ヘルプ ファイルの特定の要素へのアクセスを実現するために、Help クラスおよび HelpProvider クラスで使用されます。たとえば、F1 ヘルプを提供する HelpProvider コンポーネントで使用した場合、TopicID 値やTopic 値を指定することで、特定のコンテキストのトピックに関するヘルプを開くことができます。

使用例使用例

mspaint.chm ヘルプ ファイルと対話するための 3 つのボタンが配置されたフォームを表示するコード例を次に示します。[Show Help Index] ボタンをクリックすると、このヘルプ ファイルの [Index] タブが表示されます。[Show Help] ボタンをクリックすると、[Help Navigator] リスト内で選択されている値に基づいて、ヘルプ ファイルの内容が表示されます。[Show Keyword] ボタンをクリックすると、[Keyword] ボックスで指定されているキーワードに基づいて、ヘルプ ファイルの内容が表示されます。

たとえば、インデックス値を使って Ovals ヘルプ ページを表示するには、[Help Navigator] ドロップダウン リストで HelpNavigator.KeywordIndex 値を選択し、[Parameter] ボックスに「ovals」と入力した後、[Show Help] ボタンをクリックします。"ブラシで描くには" ヘルプ トピックをキーワードを指定して表示するには、[Keyword] ボックスに「mspaint.chm::/paint_brush.htm」と入力し、[Show Keyword] ボタンをクリックします。

ShowHelp メソッドを使用してさまざまなヘルプ タブとヘルプ トピックを表示し、ShowHelpIndex メソッドを使用してヘルプの索引を表示する例を次に示します。
