How to solve this . The process cannot access the file

Question

The process cannot access the file \'F:\\copy back up\\system\\HRM 2-5-2013\\HRM\\HRM\\lanbased.txt\' because it is being used by another process. This is my code in sub main

Answer 1

Looks like you need to close your streamReader before opening the new form:

objReader.Close()

That will free the file.

Answer 2

first you open your file for reading here :

Dim objReader As New System.IO.StreamReader(NAME1)    //1st open

Second you call the form1 : Application.Run(New Form1())

in that Form you have : Dim objWriter As New System.IO.StreamWriter(FILE_NAME) //2nd open

But wait you didn't close your file so you can't open it 2nd time for writing.

So you need to close the file before calling create form 1 like objReader.close()

        conn.Open()
        objReader.close()    <----- this one
        Application.Run(New Form1())
