Hi
I use the following line to create a text file.If I run the application again it says that it is being
used by another process. How do I ensure that this doesn't happen

     oWriter = New System.IO.StreamWriter(SYS_FOLDER & "\Customer_Invoice_Email_Queue.txt")

make sure you will close the stremwriter oWriter.Close()




Dim file As System.IO.StreamWriter
file = My.Computer.FileSystem.OpenTextFileWriter("c:\test.txt", True)
file.WriteLine("Here is the first string.")
file.Close()

on top, use USING statement:

Using file As System.IO.StreamWriter
file = My.Computer.FileSystem.OpenTextFileWriter("c:\test.txt", True)
file.WriteLine("Here is the first string.")

There are couple of ways to handle it:

1) Use `using` block as suggested by other users
2) Wrap code inside Try..Catch..Finally block, and in finally block `Close` the file.
3) You should wrap it into Try..Catch..Finally block it is possible that the file you are trying to modify is open in another application. So you can not do anything except waiting to release the file by another application.

First two point will help you to handle the case if your application is opening a file and not releasing/closing it. The last point will help if the file is in use by another application.

Hope it helps!
