So you are correct that you need to just add a few VIs that will allow you to do both sending the data to a file and out over the internet. Here is a tutorial for
developing wireless PDA applications. The IP address should be a setting on the Pocket PC, but exactly where I am not sure since it depends on the PDA you are using. I would check the documentation for that PDA and that should have information about setting the IP address. Repost if you have any other questions!
