次のコード例に示しますを使用して、 HelpProvider 4 つのアドレス フィールドを含むフォームに状況依存のヘルプを表示するクラス。The following code example demonstrates using the HelpProvider class to display context-sensitive Help on a form containing four address fields. この例では、SetHelpStringヘルプのツールヒント テキストを設定します。The example uses the SetHelpString method to set the Help ToolTip text. 状況依存のヘルプ] ボタンを使用してヘルプ カーソルをアドレス フィールドをクリックすると、指定したテキスト、ヘルプのツールヒントが表示されます。When you use the context-sensitive Help button and click the Help cursor on an address field, the Help ToolTip appears with the specified text. に、ヘルプ ファイルが表示されるアドレス フィールドにフォーカスを持つ、F1 キーを押すと、HelpNamespaceプロパティに設定されています。When you press the F1 key with the focus in an address field, the mspaint.chm Help file is displayed because the HelpNamespace property has been set to mspaint.chm. SetShowHelpが利用可能なヘルプ コンテンツを識別するには、各アドレス コントロールのメソッドが呼び出されます。The SetShowHelp method is called for each address control to identify that it has Help content available.

各インスタンスHelpProvider関連付けられているコントロールへの参照のコレクションを保持します。Each instance of HelpProvider maintains a collection of references to controls associated with it. ヘルプ ファイルを関連付ける、 HelpProvider、設定、HelpNamespaceプロパティ。To associate a Help file with the HelpProvider, set the HelpNamespace property. 呼び出すことによって提供されるヘルプの種類を指定する、SetHelpNavigatorメソッドを提供して、HelpNavigator指定したコントロールの値。You specify the type of Help provided by calling the SetHelpNavigator method and providing a HelpNavigator value for the specified control. 呼び出すことによって、ヘルプのキーワードまたはトピックを指定する、SetHelpKeywordメソッド。You provide the keyword or topic for the Help by calling the SetHelpKeyword method. 特定のトピックにヘルプを開くには、キーワードを形式で渡す必要があるtopicName.htm します。To open Help to a specific topic, the keyword should be passed in the form topicName.htm.

特定のヘルプ文字列をコントロールに関連付けるを使用して、SetHelpStringメソッド。To associate a specific Help string with a control, use the SetHelpString method. このメソッドを使用するコントロールと関連付ける文字列は、コントロールにフォーカスがあるユーザーが F1 キーを押したときに、ポップアップ ウィンドウに表示されます。The string that you associate with a control using this method is displayed in a pop-up window when the user presses the F1 key while the control has focus.

場合、HelpNamespaceプロパティが設定されていない、使用する必要があります、SetHelpStringヘルプ テキストを提供するメソッド。If the HelpNamespace property has not been set, you must use the SetHelpString method to provide the Help text. 両方を設定している場合HelpNamespaceおよびヘルプ文字列、ヘルプに基づいて、HelpNamespaceが優先されます。If you have set both HelpNamespace and the Help string, Help based on the HelpNamespace will take precedence.
