Hi, I'm new to Visual Cobol (I have Version 2.1 Upgrade with Visual Studio 2012 running in Windows 8).
In Net Express I used an OO program to call registered COM objects.
Using VC (Form Designer) I have made references to these objects: They are described as Interop.ObjectName, Type ActiveX.
But, I haven't found any explanation or instructions on how to code these objects and call their entry points.
I'd appreciate some help on the subject.

In a Visual COBOL native program you can use the same OO client classes to call COM as you did in Net Express.
From a managed code program, after you add a reference to these COM servers you would just create a new instance of the server and call its methods like any other OO class.
Intellisense should show you the available methods and the expected parameters.
What ActiveX/COM servers are these?
An example of a managed COBOL application calling the Excel COM Server can be found here:

Thank's Chris,
the COM servers are Customer made. 1 (SAP interface) in VB, the other (Elreco number plate recognition system) in C.
Your answer pushed me in the right direction after I had stumbled into an unnecessary Wrapper to call my old dll.
