Hi, Very useful tips! Thank you very much! Both ways works really good but I decided to use tfabris way of finding the comport. There is a problem to it. I cant use the full expression if Im not Admin. I get problems when I add FIND "COM" . The program i make will be out of my hands in future. I cant garantee that is will run on a computer with admin rights. Is there a work around or something I can do to make it work as a non Admin?? Thanks!
