Location: Italy                Hi All,

have a problem.
I wrote this code to create a file in a directory of my choice.
Works well on xp but will not work on Windows Vista (32bit) and Windows 7 
(32bit). Shows the error message:

An exception of IOException was not handled. The application must shut down.
Exception Error Number: 5  

  Dim f As FolderItem = SpecialFolder.windows.Child ("SmpS.txt")
  Dim t As TextOutputStream
  
 f= SpecialFolder.windows.Child ("SmpS.txt")
 
  t=TextOutputStream.Create(f)
 
  t.WriteLine Str(app.LongVersion) 
  t.WriteLine "try1"
  t.WriteLine "Try2"
 
  t.Close

How can I fix this, where am I wrong?
Thanks for the reply.

will let you create or modify files in the system folders. You will be better 
off to 
create a folder in the users AppData folder and use it to store the files for 
your application.

f = SpecialFolder.Preferences.Child("FolderName").Child("SmpS.txt")

or

f = SpecialFolder.ApplicationData.Child("FolderName").Child("SmpS.txt")
