Gewusst wie: Reagieren auf ClickOnce-Veröffentlichungsereignisse

Aktualisiert: November 2007

ClickOnce enables you to publish Windows applications to a Web server or network file share for simplified installation. For more information, see ClickOnce-Bereitstellung.

The Visual Studio core automation model (contained in EnvDTE80) has an event-handling object named PublishEvents. You can use it to detect when a ClickOnce deployment begins (OnPublishBegin) and ends (OnPublishDone). Based on these events, you can perform an action. The following procedure demonstrates how to handle those events.

Hinweis:
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. These procedures were developed with the General Development Settings active. To change your settings, choose Import and ExportSettings on the Tools menu. For more information, see Visual Studio-Einstellungen.

To respond to ClickOnce events

1. In a new or existing add-in, add the following code to the Connect class.

2. Build and activate the add-in as outlined in Gewusst wie: Steuern von Add-Ins mit dem Add-In-Manager.

3. Begin a ClickOnce deployment operation as outlined in ClickOnce-Bereitstellung.

   You see a message box display when the deployment begins and ends.
