Hello Maz -
I am curious to know if you have seen the previous discussion thread about passing variables with VB(
"How do I access TestStand Local and Runtime variables from a VB program"). While the discussion focuses on accessing from TestStand local variables, the process is the same when sending data back. Instead of using the methods along the lines of "Get..." like the other post shows, you would switch to using the "Set..." variations. The examples pointed out in one of the responses are also an excellent starting point.
If this wasn't your question, let me know a few more details about your situation.
-Regards
