Beispiele

Im folgenden Codebeispiel wird die Verwendung HelpProvider der-Klasse zum Anzeigen der kontextbezogenen Hilfe in einem Formular veranschaulicht, das vier Adressfelder enthält.The following code example demonstrates using the HelpProvider class to display context-sensitive Help on a form containing four address fields. Im Beispiel wird die SetHelpString -Methode verwendet, um den QuickInfo-Text festzulegen.The example uses the SetHelpString method to set the Help ToolTip text. Wenn Sie die kontextabhängige Hilfe Schaltfläche verwenden und auf den Hilfe Cursor in einem Adressfeld klicken, wird die QuickInfo mit dem angegebenen Text angezeigt.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. Wenn Sie die F1-Taste mit dem Fokus in einem Adressfeld drücken, wird die Hilfedatei "mspaint. chm" HelpNamespace angezeigt, da die-Eigenschaft auf "mspaint. chm" festgelegt wurde.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. Die SetShowHelp -Methode wird für jedes Address-Steuerelement aufgerufen, um zu ermitteln, dass Hilfe Inhalte verfügbar sind.The SetShowHelp method is called for each address control to identify that it has Help content available.

Hinweise

Jede Instanz von HelpProvider verwaltet eine Auflistung von Verweisen auf Steuerelemente, die ihr zugeordnet sind.Each instance of HelpProvider maintains a collection of references to controls associated with it. Um dem HelpProvidereine Hilfedatei zuzuordnen, legen Sie die HelpNamespace -Eigenschaft fest.To associate a Help file with the HelpProvider, set the HelpNamespace property. Sie geben den Typ der Hilfe an, die durch SetHelpNavigator Aufrufen der-Methode HelpNavigator und Bereitstellen eines Werts für das angegebene Steuerelement bereitgestellt wird.You specify the type of Help provided by calling the SetHelpNavigator method and providing a HelpNavigator value for the specified control. Sie geben das Schlüsselwort oder Thema für die Hilfe an, SetHelpKeyword indem Sie die-Methode aufrufen.You provide the keyword or topic for the Help by calling the SetHelpKeyword method. Um die Hilfe zu einem bestimmten Thema zu öffnen, sollte das-Schlüsselwort in der Form topicName. htm weitergegeben werden.To open Help to a specific topic, the keyword should be passed in the form topicName.htm.

Verwenden Sie die SetHelpString -Methode, um einem-Steuerelement eine bestimmte Hilfe Zeichenfolge zuzuordnen.To associate a specific Help string with a control, use the SetHelpString method. Die Zeichenfolge, die Sie mithilfe dieser Methode einem Steuerelement zuordnen, wird in einem Popup Fenster angezeigt, wenn der Benutzer die F1-Taste drückt, während das Steuerelement den Fokus besitzt.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.

Wenn die HelpNamespace -Eigenschaft nicht festgelegt wurde, müssen Sie die SetHelpString -Methode verwenden, um den Hilfetext bereitzustellen.If the HelpNamespace property has not been set, you must use the SetHelpString method to provide the Help text. Wenn Sie sowohl HelpNamespace als auch die Hilfe Zeichenfolge festgelegt haben, HelpNamespace hat die Hilfe, die auf basiert, Vorrang.If you have set both HelpNamespace and the Help string, Help based on the HelpNamespace will take precedence.

HelpProviderRuft Methoden für die Help -Klasse auf, um Hilfefunktionen bereitzustellen.HelpProvider calls methods on the Help class to provide Help functionality.
