How to find the object type of particular database table or a web part or page type or form ?

for instance I saw in one of the examples of integration bus it was mentioned to use new ObjectIntegrationSubscription(ConnectorName, TaskProcessTypeEnum.AsyncSnapshot, TaskTypeEnum.All, null,@bizformitem.bizform.%@, null); to subscribe. How can we know @bizformitem.bizform.%@is the type to b used, because it did not work when i used predefinedObjectType.bizform !
