IExtendContextMenu::Command method (mmc.h)
The IExtendContextMenu::Command method is called if one of the items you added to the context menu with IExtendContextMenu::AddMenuItems is subsequently selected. MMC calls Command with the command ID you specified and another pointer to the same IDataObject interface.
Syntax
HRESULT Command(
[in] long lCommandID,
[in] LPDATAOBJECT piDataObject
);
Parameters
[in] lCommandID
A value that specifies the command identifier of the menu item.
[in] piDataObject
A pointer to the IDataObject interface on the object whose context menu was displayed.
Return value
This method can return one of these values.
Remarks
MMC reserves negative-valued command IDs for predefined menu command IDs that it sends to a snap-in's IExtendContextMenu::Command method. The –1 command ID is the MMCC_STANDARD_VIEW_SELECT enumerator value defined in mmc.h. This is sent to IExtendContextMenu::Command when the user clicks a standard view command on the View menu (Large, Small, List, or Detail). This notifies the snap-in that the user is switching away from a custom view (OCX, HTML). After getting an MMCC_STANDARD_VIEW_SELECT command, the snap-in should request a standard view the next time its IComponent::GetResultViewType method is called and not request a custom view until one of its custom view menu items is selected. If the snap-in only uses standard views or only uses custom views, it can ignore the MMCC_STANDARD_VIEW_SELECT command.
MMC sends the snap-in the MMCC_STANDARD_VIEW_SELECT command when the user clicks the Back button on the toolbar. MMC uses this command to instruct the snap-in to display the result pane's previous view.
