Hi Gregory,

I assume you what to write/read when your Uut or an execution is running.
If I am right i would fire a PostUIMessage from the execution to C# Ui.
On reveiving this message in your UI will be able to get a handle to SequenceContext
now your world is open.

Thank's for your response,

    In fact I have a checkBox in C# UI, and I want write state of checkbox in parameter(variable) in Testand.
    I will test your solution and give you a feedback.

I have found some code on the forum, I muss use propertyObject for read or write a parameter.

this code is :

Private void Example (Step stepObj)

{

PropertyObject propertyObj;

String errorString;



propertyObj = stepObj.AsPropertyObject();

errorString = propertyObj.GetValString("Result.Error.Msg",0);

}

What is stepObj? where can I find them?

thank's.

If I understand you correctly, you want to pass the state of a checkbox to a parameter in a Sequence.

What you dont specific is whether this is during the execution of the Sequence or not.

I think your best bet would be to write the state of your Checkbox to the StationGlobals. Then let your Sequence pickup the value from the StationGlobals.

Hi Ray,

I agree your suggestion.

Hi  Costello,

for more information on C# and TS take a look at the example <ProgramFolder>\National Instruments\TestStand 4.0\Examples\Demo\DotNet

Hello Ray, you have understand my problem. I have try to write in StationGlobal, but It don't functions, I have Testand 4.1.
I have try some exemple for write in StationGlobal, but any function.
Have you an exemple?


Hi Juergen, I have see the computer exemple, but that is not a GUI exemple, that is a dll.
