To lock a file you can use something like this. Keep in mind this is not tested. Also remember to import System.IO

Private Sub LockFile(ByVal file As String)

    Dim FileSt As FileStream = New FileStream("test.dat", FileMode.Create, FileAccess.Write, FileShare.Write)
    Try
        FileSt.Lock(0, FileSt.Length)
        Debug.WriteLine("Locked")
    Catch Ex As Exception
        Debug.WriteLine(Ex.Message)
    End Try

End Sub

Private Sub UnlockFile(ByVal file As String)

    Dim FileSt As FileStream = New FileStream("test.dat", FileMode.Create, FileAccess.Write, FileShare.Write)
    Try
        FileSt.Unlock(0, FileSt.Length)
        Debug.WriteLine("Unlocked")
    Catch Ex As Exception
        Debug.WriteLine(Ex.Message)
    End Try

End Sub
