[RESOLVED] Accessing text files

In this program i am making, i want to get information from a text file. but i need to get it from 2 different subs. one sub loops and gets the information every loop and other gets it when a user clicks a button. when they get it at the same time, i get an error saying that it is already being used by another process.

Probably you forget to close the stream after finishing reading the file.
Show us your code.

Why do you need to allow the user to get the information manually when one sub is constantly looping and getting the information?

Im not using a stream to access the file. Im just using IO.File.ReadAllText. I need to get the information 2 times because the loop writes the information using graphics.drawstring and the other sub changes the text in the file.

Can you post the relevant code instead of having us trying to guess what the problem is?

Code:

---

If Not IO.File.Exists("C:\Text.txt") Then
                        IO.File.WriteAllText("C:\Text.txt", 10)
                    Else
                        IO.File.WriteAllText("C:\Text.txt", IO.File.ReadAllText("C:\Text.txt") - 1)
                    End If

---

Code:

---

Do
Me.CreateGraphics.DrawString(IO.File.ReadAllText("C:\Text.txt") , New Font("Microsoft Sans Serif", 8.25), Brushes.Yellow, 150, 15)
Loop

---

I'm pretty sure the error is on this line:

Code:

---

IO.File.WriteAllText("C:\Text.txt", IO.File.ReadAllText("C:\Text.txt") - 1)

---

When you call File.WriteAllText, it creates streamwriter internally to write to that file so the file is being locked. You then immediately do a File.ReadAllText on the same file that is being open for write.
What you need to do is read the file first, then wrtie to it.
Try this:

Code:

---

If Not IO.File.Exists("C:\Text.txt") Then
      IO.File.WriteAllText("C:\Text.txt", 10)
Else
    Dim currentValue As Integer = Integer.Parse(IO.File.ReadAllText("C:\Text.txt")
    IO.File.WriteAllText("C:\Text.txt", (currentValue -1).ToString())
End If

---

End If

thanks, it works!
