Using Automation Interface to Edit ST Program

Editing the content of a mimic, trend or logic program can be done through the use of the ViewX automation interface. This interface allows an application to connect to ViewX rather than the database server.

The program below, written in Visual Basic, uses the standard automation interface to both connect to the server, create a logic program, then connect to ViewX and configure the code for that program.
