Parallel calls to ActiveX using Invoke Node

[_Y_]

Dear colleagues,

Please help/advice on such a problem.

• The program has a VI template (template.vit) having an ActiveX.
• Two calls to this template create different instances of the ActiveX with different reference numbers.
• Two asynchronous processed invokes the same function of the ActiveX supplying two different refs to Invoke Nodes. Execution of the function takes significant time.

Apparently functions of two instances are not executed asynchronously. The second waits until accomplishment of the first.

Please advice how the problem can be approached/solved. We need independency of the calls.

PS: Most of the tests were done with LabVIEW 8.6.1

Thank you
