Sending an int value to an Arduino to operate a Digital Potentiometer

Hello,

I have a digital potentiometer that I have got working with some arduino code, and I am now attempting to pass an int value to the arduino code through labview in order to control the resistance with a lab view dial.  I am having trouble figuring out a way to do this, as VISA and LINX don't have a way (unless I missed something) to pass an integer.  Could I potentially do this by converting a String (which I am able to send to the arduino through labview) into an integer?

Thanks,

J
