GetPersistReference3 Method (IModelDocExtension)

Gets the persistent reference ID for the specified object in this model document.

.NET Syntax

Visual Basic (Declaration) 
Function GetPersistReference3( _
   ByVal DispObj As System.Object _
) As System.Object
Visual Basic (Usage) 
Dim instance As IModelDocExtension
Dim DispObj As System.Object
Dim value As System.Object
value = instance.GetPersistReference3(DispObj)
System.object GetPersistReference3( 
   System.object DispObj
System.Object^ GetPersistReference3( 
&   System.Object^ DispObj



Return Value

Array containing the persistent reference ID assigned to that object



Persistent reference ID values obtained using the now obsolete IModelDocExtension::GetPersistReference and its related obsolete methods, IModelDocExtension::GetPersistReferenceCount and IModelDocExtension::GetObjectByPersistReference2, are not compatible with persistent reference IDs obtained using this method and its related methods, IModelDocExtension::GetPersistReferenceCount3 and IModelDocExtension::GetObjectByPersistReference3 or IModelDocExtension::IGetObjectByPersistReference3.

A persistent reference ID is related to a model. It is portable and can be saved within the model or in other places. Some persistent reference IDs are general to all models and can be instantiated from all models. Your application must handle persistent reference IDs and their relationships among models.

The internal representations of the return value array may change, possibly from rebuild to rebuild, or more likely, from one release of SOLIDWORKS to the next, but their usage in finding the correct entity will be consistent across rebuilds and SOLIDWORKS releases.

To compare the referenced entities, you could use the Visual Basic Is operator to find out if the entities are the same.

See Persistent Reference IDs for more information.
