Parameters

Remarks

This method invokes the ISelectionService interface.

Base class implementation adds command handlers only if a handler is not already registered. This enables derived classes to override the handling of each command. Therefore, derived classes should add commands before they call the base class.

Examples

This example adds a custom command to the shortcut menu. When a user builds a solution in the generated designer and right-clicks the diagram, one additional command, Sample Command, appears in the shortcut menu.

In the Commands.vsct file, the following line appears after the include statements.

#define cmdidMyMenuSample  0x0008

In the Commands.vsct file, the following line appears after GENERATED_BUTTONS.

guidCmdSet:cmdidMyMenuSampe, guidCommonModelingMenu:grpidExplorerMenuGroup, 0x8020, OI_NOID, BUTTON, DIS_DEF, "&Sample Command";

Within the VsctComponents folder, the following .cs file is available.The namespace and some of the methods have the name of the project, MenuSample, in them.
