Use the ActiveX/COM Adapter to create ActiveX/COM objects, call methods, and access properties of those objects. When you create an object, you can assign the object reference to a variable or property for later use in other ActiveX/COM Adapter steps. When you call methods and access properties, you can specify an expression for each input and output parameter. Use the ActiveX/COM Adapter Configuration dialog box to configure the ActiveX/COM Adapter.

When you specify a module for a step, the TestStand Sequence Editor displays the ActiveX/COM Module tab, and the TestStand User Interfaces launch the Edit ActiveX/COM Call dialog box.
