Comments

The host implements OnSelectChange.

The ActiveX designer calls OnSelectChange, passing a pointer to its implementation of the ISelectionContainer interface. As the user browses and edits the objects, the host calls the methods supported by ISelectionContainer to manage the selection.

Through the CountObjects, GetObjects, and SelectObjects methods, the selection container enables enumeration and selection of one or more objects.

Example

The following example calls OnSelectChange to pass a pointer to pISC, a selection container interface. The host can call CountObjects, GetObjects, and SelectObjects through this pointer.

hr =  m_state.pServiceProvider->QueryService(SID_STrackSelection, 
                         IID_ITrackSelection,
                         (void **) &pITS);
hr = pITS->OnSelectChange(pISC);
pITS->Release();
