Changing data in a Tab Delimited text files

I have a tab delimited text file that contains 26 fields and anywhere from 1 upwards rows.

The rows can contain information in all 26 fields or only the first field.

The sixth field is currently empty (Class). If the first column contains TRNS or SPL I need to put information into the sixth field and copy this to a new tab delimited text file (or update the original).

I have been able to read the test file into a recordset, however this recordset will not allow me to update field (5). I have also writen script to write from the first recordset toa new tab delimited file. Can some one tell me how when writing to the new file, I will be able to add information to field 5 of the recordset if the above requirements are met.

Regards

Here you go,

Private Sub Form_Load()

Const FILENAME As String = "c:\temp.csv" ' the file to read
Const NEWFILENAME As String = "c:\temp1.csv" ' the newfile to create

Dim FNUM As Integer
Dim FNUM1 As Integer
Dim TEMP As String
Dim FIELDS() As String
Dim I As Long
Dim NEWLINE As String

FNUM = FreeFile
FNUM1 = FreeFile
Open FILENAME For Input As #1
Open NEWFILENAME For Output As #2

While Not EOF(1)
Line Input #1, TEMP
FIELDS = Split(TEMP, vbTab)
If FIELDS(0) = "TRNS" Or FIELDS(0) = "SPL" Then ' check for criteria
FIELDS(5) = "TheNewValue" ' set the new value
End If
NEWLINE = ""
' construct the new line
For I = 0 To UBound(FIELDS)
NEWLINE = NEWLINE & FIELDS(I)
If UBound(FIELDS) <> I Then NEWLINE = NEWLINE & vbTab
Next
Print #2, NEWLINE
Wend
Close #1
Close #2
End Sub
