次のコード例では、Mspaint.exe ヘルプファイルを操作するために使用できる3つのボタンを含むフォームを表示します。The following code example displays a form that contains three buttons that can be used to interact with the Mspaint.chm Help file. [ヘルプインデックスの表示] ボタンをクリックすると、ヘルプファイルの [インデックス] タブが表示されます。The Show Help Index button displays the Index tab for the Help file. ヘルプの [表示] ボタンをクリックすると、ヘルプファイルの内容が [ヘルプナビゲーター] の一覧で選択した値に基づいて表示されます。The Show Help button displays content in the Help file based on the value that is selected in the Help Navigator list. [キーワードの表示] ボタンをクリックすると、キーワードテキストボックスで指定された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。The Show Keyword button displays content in the Help file based on the keyword that is specified in the Keyword text box.

たとえば、楕円のヘルプページをインデックス値で表示するには、[ HelpNavigator.KeywordIndex ヘルプナビゲーター ] ドロップダウンリストで値を選択し、[パラメーター] ボックスに「楕円」と入力して、[ヘルプの表示] ボタンをクリックします。For example, to show the Ovals Help page by the index value, select the HelpNavigator.KeywordIndex value in the Help Navigator drop-down list, type ovals in the Parameter text box, and then click the Show Help button. キーワードを使用して "ブラシで塗りつぶす" ヘルプトピックを表示するには、[キーワード] ボックスに「 mspaint.exe::/paint_brush.htm 」と入力し、[キーワードの表示] ボタンをクリックします。To show the "To paint with a brush" Help topic by the keyword, type mspaint.chm::/paint_brush.htm in the Keyword text box, and then click the Show Keyword button.

この例ではShowHelp 、メソッドを使用して、さまざまなヘルプタブとヘルプShowHelpIndexトピックを表示し、メソッドを使用してヘルプインデックスを表示します。The example uses the ShowHelp method to display the different Help tabs and Help topics, and the ShowHelpIndex method to display the Help index.

Helpクラスの新しいインスタンスを作成することはできません。You cannot create a new instance of the Help class. アプリケーションのヘルプを提供するには、静的ShowHelpメソッドShowHelpIndexとメソッドを呼び出します。To provide Help for an application, call the static ShowHelp and ShowHelpIndex methods.

を使用Helpすると、コンパイルされたヘルプファイル (.chm) または html ファイルを html ヘルプ形式で表示できます。You can use Help to show compiled Help files (.chm) or HTML files in the HTML Help format. コンパイルされたヘルプファイルは、目次、インデックス、検索機能、およびページ内のキーワードリンクを提供します。Compiled Help files provide a table of contents, an index, search capability, and keyword links in pages. ショートカットは、コンパイルされたヘルプファイルでのみ機能します。Shortcuts work only in compiled Help files.

Html ヘルプ1.x ファイルは、HTML ヘルプワークショップを使用して生成できます。You can generate HTML Help 1.x files by using HTML Help Workshop. HTML ヘルプの詳細については、 MICROSOFT htmlヘルプの「Html ヘルプワークショップ」および他の html ヘルプトピックを参照してください。For more information about HTML Help, see "HTML Help Workshop" and other HTML Help topics at Microsoft HTML Help.
