How to get execution object for SetRunModeEx?

[Snood1]

I would like to know how to get an execution object for use with the function TS_StepSetRunModeEx.  I am using TestStand 3.1, calling CVI 7.1 code.

Pass in the SequenceContext and then you can get the execution from that.  Or just pass in SequenceContext.Execution.  You may have to change it to a variant.

I am using TS_SeqContextGetExecution to get the execution object, but I get the error 0x80004005 (Unspecified Error) when I do.  In TestStand I declared an object reference named "MainSequenceContext."  In CVI I get the variable "Locals.MainSequenceContext" using TS_PropertyGetValIDispatch.  The variable is of type CAObjHandle and is named: oMainSequence.  I can use oMainSequence for functions like TS_SequenceGetNumSteps and it works fine.

Hey Snood,

After you get the Obj Handle for the Execution are you converting it to a Variant before passing it to the set step mode call?  Try:

CA_VariantSetObjHandle

Then you can pass it into the TS_StepSetRunModeEx

Please understand that I can't get the execution object handle at all because I get the aformentioned error generated by TS_SeqContextGetExecution.

Here is some code that should do the trick:

void __declspec(dllexport) setStepExec(CAObjHandle step, CAObjHandle context)
{
VARIANT execVariant;
LPDISPATCH execDispatch;
int error = 0;
CAObjHandle execObj;
TS_SeqContext
ERRORINFO errorInfo;
TS_SeqContextGetExecution (context, &errorInfo, &execObj);
CA_GetDispatchFromObjHandle (execObj, &execDispatch);
execVariant = CA_VariantDispatch (execDispatch);
TS_StepSetRunModeEx (step, &errorInfo, "Skip", execVariant);

Error:
if (error < 0)
{

}
}

There are probably memory leaks however but that is the gist of it.

This code will probably work, but I should still get the same error when I call TS_SeqContextGetExecution.  For some reason it must not like the object handle I got from TS_PropertyGetValIDispatch.  Yet it likes it okay for a function like TS_SequenceGetNumSteps.

The thing that would be most helpful would be assistance in figuring out why I get an error when calling TS_SeqContextGetExecution.

I would like to try another angle:

Here is the function prototype for TS_SeqContextGetExecution.

RESULT CVIFUNC TS_SeqContextGetExecution (CAObjHandle objectHandle, ERRORINFO *errorInfo, TSObj_Execution *val);

Can you tell me how to get the objectHandle property?

Hey Snood1,

The ObjectHandle would be the sequence context passed from TestStand into CVI.  Basically it contains all the information about the state of the current execution.  You should have an example that shows how to get the sequence context into your dll: <TestStand>\Examples\AccessingPropertiesAndVariables\PassingSequenceContextToDLL  It was written in CVI so it demonstrates what you are looking for. 

I hope this helps.  Let me know if there's anything else.
