Using UIMSG_Trace

Recommended Posts

Dear Members,

 

Is anyone utilised the Default Teststand UI Messages?

 

Whenever a step is executing I m getting the UIMSG_Trace(4) Event from Teststand to LabVIEW User Interface. I m trying to use the same to know the current step executing and the status of it and I could get the current step executing but i m not getting the status of the step executed.

 

Below are the Procedure I m following to run the sequence.

1. Run Test UUTs (Running Sequential Model Directly)

2. Enter Serial Number

3. Load Client file based on serial number entered.

Below are the LabVIEW code i m using to get he Step info through UIMSG_Trace Event.

Here I need to take only the name of current subsequence executing and its status.

I M getting the name of subsequence here, but the status is showing running ,like below formate

Testcase1-->Running

Testcase1-->Running

Testcase2--> Running

Testcase2-->Running

 

Please help me to find the solution for above requirement

Hi Vipinraj,

I don't think you can get what you need from the trace event, at least I have never got it to work. This is how I get the step result, this is using C# .NET rather than LabVIEW but the call parameters and property names are very similar:

SequenceContext context = e.uiMsg.Thread.GetSequenceContext(0, out frameId);
PropertyObject resultList = context.Locals.GetPropertyObject("ResultList", 0);
int numElements = resultList.GetNumElements();
if (numElements != 0)
{
  PropertyObject lastResult = resultList.GetPropertyObjectByOffset(numElements - 1, 0);
  string status = lastResult.GetValString("Status", 0); // "Done", "Passed", etc. depending on step type
}

Note: the result for the currently-executing step has not yet been posted into ResultList, so I think you get the result for the step preceding the one being traced. There may well be a better way to do this but it is hard to find out especially as the documentation is not good, repeated trial and error is my usual MO! If you have found how to do it differently please post here as it will be useful to me :-)
