Activex and .net Labview Teststand

[Lunik]

Hello

I had a problem when i use a .net assembly in teststand

• I created a VI and in this vi i use "this.context" activex for receive the teststand context
  • When i use the VI in teststand everitging work
• Now I built a assembly .net from the VI
• The assembly doesn't work
• Teststand message error "Object of type 'System.__ComObject' cannot be converted to type 'NationalInstruments.LabVIEW.Refnums.LVBaseRefnum"

I think activeX doesnt work in .net assembly

How i suppose to fix this issue ?

Thanks you

Hello Lunik,

If i understood correctly, you created a LabVIEW VI in which you use ActiveX.

When trying to call a .NET assembly in this VI, it doesn't work anymore.

My first question would be: do you know that you can call .NET assemblies directly in TestStand?

If yes, what is the result?

Have a nice day!

Regards,

Armando

Hi folks,

I have exaclty the same issue.

I have a LV library which needs "SequenceContext" object as input parameter

I need to call the library from C#. So I'm creating a LV DLL for .NET.

Application build generate a .NET function with LVBaseRefnum as parameter.

How can I convert SequenceContext object into LVBaseRefnum?

Thanks for your help
