    I haven't tested the code, but could you replace the code with this, to see if it logs the length of ListJob.

    var ListJob = AppProcess["FindAllChildren"](ArrProps,ArrVals,1000);

// Replace the above with this

var ListJob = AppProcess["FindAllChildren"](ArrProps, ArrVals, 1000)["toArray"]();
Log["Message"]("Total number of ListJob: " + ListJob["length"]);

    Hi rraghvani,

    Thank you so much for your response, converting it toArray worked!! 

    Thanks,

      I haven't touched C++ for many years, so I am a bit rusty with C++ coding!

      Without ["toArray"]() it will return a memory reference of the object. So you need ["toArray"]() to convert to an array of objects. You can access object properties such as length of the array via ["length"]

      JavaScript is less complicated and easier to understand. C++ is very old now.
