Systems AnalystTry:
f4 = f3.OpenTextFile(server.MapPath("visitor.txt"), 1)
Unless you've set up some unique permissions, by default the web project runs under the ASPNET user which by default does not have write access. You are attempting to open a file in write mode...changing to 1 opens it in read mode only. Alternatively, give ASPNET user write permissions on that directory.
What trust level are you running your app in? My first instinct is that Server.MapPath isn't allowed because of your trust level. Even in medium trust you should be able to do FileIO in your own vdir. You can replace your server.MapPath call with something like:
Path.Combine( Request.PhysicalApplicationPath, "visitor.txt" )
Let me know if that solves the problem, if it's still broken, I'll help you investigate further.
