Remarks

When using the IClassSchemaEdit2 object to alter an object class' class schema, you should first acquire an exclusive schema lock using the ISchemaLock interface to be sure that another application or user does not have the class open while you are trying to modify its schema.

You can QI for the IClassSchemaEdit2 interface from the IObjectClass interface.
