How to use GetValStringByOffset?

[Rafi2003]

HI,

I'm tyring to use the function GetValStringByOffset from CVI....

It seems like the function I need but, were is the lookup string?

What I'm trying to do is to get an element of array from TestSTand.

Example.   the 3rd element of FileGlobal.myAarray  (Array of 10 strings)

Can you show me how to do it?

Thanks

Hi Rafi,

Here is some code to get your element of the string array.

#include "stdtst.h"
#include "tsutil.h"

void __declspec(dllexport) GetStringFromArray(CAObjHandle propertyObject, char returnString[1024], short *errorOccurred, long *errorCode, char errorMsg[1024])
{
    int error = 0;
    ErrMsg errMsg = {"Error with GtValStringByOffset"};
    ERRORINFO errorInfo;
    //char *lastUserName = NULL;
 char *str=NULL;
 
    // INSERT YOUR SPECIFIC TEST CODE HERE

    // The following code shows how to access a property or variable via the TestStand ActiveX API
    tsErrChk (TS_PropertyGetValStringByOffset (propertyObject, &errorInfo, 3, 0,
                                 &str));

 
 strcpy(returnString, str);

Error: 
    // FREE RESOURCES
    // if (lastUserName != NULL)
//    CA_FreeMemory(str);

    // If an error occurred, set the error flag to cause a run-time error in TestStand.
    if (error < 0)
        {
         *errorOccurred = TRUE;
   
        // OPTIONALLY SET THE ERROR CODE AND STRING
        *errorCode = error;
        strcpy(errorMsg, errMsg);
        }
}
