Hi oktayoki,

Can you give us more details about what is happening?

What version of TestStand are you using?

Does this occur when you are editing or running?

Are you using any other software in conjunction with TestStand such as LabVIEW?

Can you provide screen shots?

Hi JDragon,

we are using Teststand V14 and this is accure while running. we are using some DLL which writed on .NET to communicate with variable powersupply and DMM

Screen shot of the error is below

Hi Oktayoki,

Thanks for the info. This doesn't seem to be a TestStand issue.

Have you tried running the code independently?

Is it 3rd party code or did you develop it in LabVIEW/CVI/Measurement Studio?

Does it occur at some point in the code or immediately after it's run?

I highly recommend adding debugging to your code (outside of TestStand) to catch errors or narrow down where this is happening.

Code is working without communicaiton.

we developed the DLL at .NET (activex) and else is at Teststand. nothing else

it occures some point in the code randomely.

our code is fine if we dont use standart RS232 communcation. But we couldnt find anything yet

Hi oktayoki,

Just to clarify; does the dll work independently of TestStand? Even with RS232 communication, does the dll work in a text-based environment or in the development environment?
