questions about writing files

[Larry Chen]

Hi,

I want to do the following:

declare a file stream and a writer in subroutine A
and perform the actual write operation in subroutine B.

How should I do it ?

( I believe this should be simple, but I am novice to vb.net )

TIA

Larry

or

Private Sub A()
Private m_Writer As StreamWriter
m_Writer = New StreamWriter(...)
B()
End Sub

Private Sub B(m as StreamWriter)
m_Writer.WriteLine(...)
End Sub

Private Sub A()
Private m_Writer As StreamWriter
m_Writer = New StreamWriter(...)
B()
End Sub

Private Sub B(m as StreamWriter)
m_Writer.WriteLine(...)
End Sub
