Mapping COM and TIBCO ActiveEnterprise Data Types


Parameters of TIBCO ActiveEnterprise methods and COM methods must be of equivalent types. Likewise, if a single parameter of a COM method is associated with a Publication or Subscription Service, the COM type of this parameter must correspond to a TIBCO ActiveEnterprise type.

The table below shows the mapping between COM (or VB types) and TIBCO ActiveEnterprise types:
