[C#]
public int OnPopup (
    object Hook

HRESULT OnPopup(
  IDispatch* Hook
);
[C++]

Hook is a parameter of type IDispatch

Product Availability

Description

hook is a reference to an IApplication object.

Remarks

The OnPopup method occurs just before the menu containing the MultiItem is displayed. OnPopup provides a hook to the application object that instantiated the MultiItem and is also used to set the number of items in the MultiItem.

When implementing IMultiItem to create a custom multiItem, use the OnPopup method to get a hook to the application. Also, write code to determine how many items will make up this multiItem and return that number using IMultiItem_OnPopup.
