Dear khan,

from the VB.NET help:
Imports System
Imports System.IO

Class Test
Public Shared Sub Main()
' Create an instance of StreamWriter to write text to a file.
Dim sw As StreamWriter = New StreamWriter("TestFile.txt")
' Add some text to the file.
sw.Write("This is the ")
sw.WriteLine("header for the file.")
sw.WriteLine("-------------------")
' Arbitrary objects can also be written to the file.
sw.Write("The date is: ")
sw.WriteLine(DateTime.Now)
sw.Close()
End Sub
End Class

Best Regards,

HKSHK

Take out the new. File.Open returns a FileStream object - you don't
have to create it:

Dim fs As FileStream = File.Open (DestinationLoc, _
FileMode.OpenOrCreate, FileAccess.ReadWrite)

Hmm, looking further - you could simplify this code:

Dim s As New StreamWriter ("c:\Stream.txt")
s.WriteLine ("This....")
s.WriteLine ("This con...")
s.Close ()

Of course, you might want to do some error trapping in there in real
life :)
