TextField Parser - writing to files..

[ltfcphil]

Sorryif I'm a bit of a noob here, but can any one advise me on if/how it's possible to write to files using the MY object text field parser, or suggest another method of amending records in files using delimiters.
Below is how I read from the file:

Dim x As Integer
Dim AClass As String
Dim currentRow As String()
Dim rowlen As Integer

Using Myreader As New _
Microsoft.Visua lBasic.FileIO.T extFieldParser( "SBData_Class.d at")
Myreader.TextFi eldType = FileIO.FieldTyp e.Delimited
Myreader.SetDel imiters(",")

While Not Myreader.EndOfD ata
'pull out records and write to textbox
Try
currentRow = Myreader.ReadFi elds
rowlen = currentRow.Leng th

For x = 0 To rowlen - 1
AClass = currentRow(x)
textBox1.Items. Add(AClass)
Next


Catch ex As Microsoft.Visua lBasic.FileIO.M alformedLineExc eption
MsgBox("Line " & ex.Message & _
"is not valid and will be skipped.")
End Try
End While
End Using

Many thanks,
Phil
