Security.Permissions issue

Question

Thank you in advance. I'm writing some simple EDI processing software for my sales department and I ran into an issue with Permissions. I'm a converted java programmer so this .NET security stuff is greek to me. My application runs fine when its on a local machine, obivously cause its fully trusted, but as soon as I move it to a network share I get the an error involving FileIO. I disabled the caspol on our dev server but I still get the error. My current FileIO objects are try{ StreamReader sr = new StreamReader(infile) StreamReader sw = new StreamReader(outfile) (some code) } Can anyone help me understand how this PermissionSet thing works well enough so I can get it to read/write files while its on a local share? Thanks again J. Holt
