[RESOLVED] Problem with writing a string to a file several times

Hi I'm having issues regarding writing several strings to a txt file.

The sub starts like this

Code:

---

Dim ss As New FileStream("Settings.conf", FileMode.OpenOrCreate, FileAccess.ReadWrite)
        Dim s As New StreamWriter(ss)

---

Writing and close

Code:

---

            s.BaseStream.Seek(0, SeekOrigin.Begin)
            s.WriteLine(info.StoreName)
            s.WriteLine(info.aName)
            s.WriteLine(info.aID)
            s.Close()

---

But when i click the button several times, it says that the file is being used by another process. My guess is that s wasn't closed?

Edit: Also, how do I enable a button after clicking another button?
