Use Teststand step comment field in CVI 8.1

Question

Hi,
In the past we used Teststand 2.0. 
We used the comment field of a step to pass variable to CVI.
We used the following code to do this
tsErrChk (TS_SeqContextGetProperty (testData->seqContextCVI, &errorInfo,TS_SeqContextStep, CAVT_OBJHANDLE,&objhStep));
tsErrChk (TS_StepAsPropertyObject (objhStep, &errorInfo, &objhPropertyObject));
tsErrChk (TS_PropertyGetProperty (objhPropertyObject, &errorInfo,TS_PropertyComment, CAVT_CSTRING, &CommentStr));
Now, we use Teststand 4.2. In Teststand 4.2 the argumentlist of a function has changed. So this code does not work.
How can i read the comment field from a teststep in Teststand 4.2 into CVI 8.1 ?
How can i get the name from the used seq file in CVI 8.1 >
Thanks in advance

Hi
I have added the seqContextCVI object to the argumentlist of my function
void __declspec(dllexport) Meet(double *measurement, char reportText[1024], short *errorOccurred, long *errorCode, char errorMsg[1024], CAObjHandle seqContextCVI)
    int error = 0,State=0;
    ErrMsg errMsg = {'\0'};
    ERRORINFO errorInfo;
    static CAObjHandle objhPropertyObject, objhStep;
    static char *CommentStr1,*CommentStr2;
    //First try
    tsErrChk(TS_PropertyGetComment (seqContextCVI, NULL, &CommentStr));
    sscanf (CommentStr1, "State=%i",&State);
    //Second try
    tsErrChk (TS_SeqContextGetProperty (seqContextCVI, &errorInfo,TS_SeqContextStep, CAVT_OBJHANDLE,&objhStep));
    tsErrChk (TS_StepAsPropertyObject (objhStep, &errorInfo, &objhPropertyObject));
    tsErrChk (TS_PropertyGetProperty (objhPropertyObject, &errorInfo,TS_PropertyComment, CAVT_CSTRING, &CommentStr2));
    sscanf (CommentStr2, "State=%i",&State);
    *measurement = testMeasurement;
Error: 
    if (error < 0)
        // *errorOccurred = TRUE;
        // OPTIONALLY SET THE ERROR CODE AND STRING
        // *errorCode = error;
        // strcpy(errorMsg, errMsg);
I treid to read the comment field in 2 different ways
The first way is not working. The second way works fine.
Why is the first way not working
Thanks in advance
