Thread Safety

Any public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Any instance members are not guaranteed to be thread safe.

Remarks

MenuCommand represents information about a Windows menu or toolbar command. The IMenuCommandService interface allows you to add MenuCommand objects to the Visual Studio .NET menu.

This class provides the following members:

• An event-handler property to which you can attach an event handler for the command.
• A CommandID property that uniquely identifies the command.
• An Invoke method that executes the command.
• An OnCommandChanged method that can be overridden to handle the event that occurs when a new command is selected.
• Boolean flag states that indicate whether the command is Checked, Enabled, Supported, or Visible.
• An OleStatus property that indicates the OLE command status code for the command.
• An override for ToString.

Example

[Visual Basic, C#, C++] This example creates a MenuCommand object, configures its properties, and adds it to a IMenuCommandService object.

[Visual Basic] 
' This example illustrates how to add a command of type StandardCommand to a
'   service of type IMenuCommandService.  It defines a class that is a designer
'   to a component, called CDesigner.  Then it creates a MenuCommand object using
'   one of the commands in the StandardCommands class.  Finally, it sets several
'   of the properties in the MenuCommand object and adds the MenuCommand object
'   to the MenuCommandService object.
