    hi Shankar_r,

     

    thank you for your reply,

    i was lost and don't know how to start writing the code but your code help me to kick start writing, i will keep your code for future reference, thanks a lot.

     

    This is what i manage to come up with :

     

    var ABC = 123;

    if(isNaN(ABC))
{
  Log.Message(ABC + " is not a number");
}
else
{ 
  Log.Message(ABC + " is a number");
}

     

    this code work well without any problem for me, i am not sure if this is the correct code for test complete because NaN is what i get from jscript, hopefully it won't cause any bug in future, haha ..

A simple solution is,

 

function isNumaric(){
      
      try{
            if(aqConvert.StrToInt(str)){
                  Log.Checkpoint("Coverted Sring to Int <" + str + ">");
            }
      }catch(ex){
            Log.Error("Unable covert Sring to Int <" + str + ">");
      }
}
