Determines whether a specific property sheet exists.
HRESULT FindPropertySheet(
  long cookie,  // Managed object's cookie
  LPCOMPONENT lpComponent,
                // Pointer to the component that owns the cookie
  LPDATAOBJECT lpDataObject
                // Pointer to the data object for the cookie
);
 Items in the scope pane are owned by the console so there is no need to interact with the IComponentData interface. The snap-in must implement IComponent::CompareObjects or IComponentData::CompareObjects to compare the data object for this cookie with all other cookies for existing property sheets.
