Microsoft COM+ Objects

building multi-tiered, distributed applications. The following examples

provide the steps required to create and use a simple COM+ object in a

FactoryTalk Transaction Manager configuration using Microsoft Visual

Basic. Some sections are optional, but they are included to demonstrate the

ability to reuse and distribute COM+ objects.
