The Guide Store calls the ItemsChanged callback method when two or more Channel objects in the Channels collection obtained from IGuideStore::get_Channels have been changed, added, or removed.
Syntax
HRESULT ItemsChanged();
Parameters
This method takes no parameters.
Return Values
Return values are implemented by the application. If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Remarks
This method is called when a call to IGuideStore::CommitTrans caused more than one change in the collection. In this case, an event is not triggered for each change.
The dispatch identifier (dispid) of this method is didItemsChanged.
