passing a string from c# to RunState.Root.Locals.UUT.SerialNumber at NI

[NewSCRUser]

HI all,

How can I pass a variable content as a string in c# to the sequence variable named as RunState.Root.Locals.UUT.SerialNumber.

The main gold is to pass the string value from textbox in c# GUI to the sequence parameters.

Tnx

Please check this example :

TestStand 2012\Examples\AccessingPropertiesUsingAPI\UsingDotNet\AccessingPropertiesDotNet

It shows how to set a TestStand Variables from a C# enviornment.

Hope this helps.

Hi all,

I'm using C:\Users\Public\Documents\National Instruments\TestStand 2013\UserInterfaces\Full-Featured

and I'm trying to get the sequenceContex object :    SequenceContext s= axExecutionViewMgr.SequenceContext;

I always get exception "You must pause the execution."

How should I do that??

The main gold is to set RunState.Root.Locals.UUT.SerialNumber at run-time by using c# application(full-featured example).

Use an User Interface Message (short UIMsg) to query the DUT serial number in the Pre-UUT callback.

Hi Norbert,

I don't need to query the serialNumber ,I need to set the serialNumber at runTime.

On Full featured GUI project I don't know how to access to serialNumber runstate variable.

I'll appriciate your time.

Hi Juergen,

When I start the execution of the sequence I would like to send the serialNumber string from my application(In this case Full Featured GUI example c#) to the RunState.Root.Locals.UUT.SerialNumber variable on NI.

Tnx

Hi

there a serveral ways to do this task. But you should do it in that way Norbert_B has descriped by using UserInterface Messages.
In general, TestStand is not only one process. Your UI is another process. You have to share information over processes.

The recommed way for doing this here is fireing UI messages. From TestStand execution you send a message to your UI. Once you have received this message in your UI, you can get a handle to the current sequnceContext were you are able to set your UUT number.

I am pretty sure that Norbert can explain this more in detail. 🙂 because i am out of time now.
