While the Visual Studio automation model makes it easy to place add-in commands on top-level menus, such as on the Tools menu, you can also add commands to shortcut menus and submenus.

To do this, though, you must use the Microsoft Visual Studio Command Bar object model to explicitly define the target shortcut menu and submenu. You must then call the Visual StudioAddControl method.

Shortcut menus are similar to other menus in Visual Studio.To access them, you point to a down arrow in a dropdown menu, or you right-click an item in the integrated development environment (IDE).

To add a command to a shortcut menu (or any menu or toolbar), you must first know its command name. You could find it by searching through the Keyboard node in the Options dialog box on the Tools menu. An available add-in sample searches for a particular menu item, and it then returns its command name and other related information. This add-in sample is named "Command Browse Add-in" and it is located on the Visual Studio A site. (To access the add-in, unpack the project, build it, run the accompanying AddinReg.reg file, and then click the Command Browser command on the Tools menu.)

The following procedure demonstrates how to add an add-in command to the Task List's shortcut menu.

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.

On the File menu, point to New, and then click Project.
In the New Project dialog box, expand Other Project Types, click Extensibility, and then click Visual Studio Add-in in the Templates pane.

Name the add-in ContextCmd and click OK to start the Visual Studio Add-in Wizard.
Select the option to create a user interface (UI) for the add-in by checking the Would you like to create a command bar UI for your add-in? box.

This adds some UI code to the OnConnection method. It also adds the Exec method, which handles the event when someone clicks the add-in command, and the QueryStatus method, which provides information on the status of the add-in.

Replace the code with the following:

End Class

Add the code that you want to run when the command is clicked in the Exec procedure.
Build the add-in and then run it.
Display the Task List by clicking Task List on the View menu.
On the Tools menu, click Add-In Manager.
Activate the ContextCmd add-in by checking the box next to it in the Add-In Manager.
Right-click the Task List.

The ContextCmd add-in command appears on the shortcut menu.
