vb6 read and evaluate fields from a .csv file?

$

Hi all,

I have a .csv file and I need to evaluate certain fields inside of it. I thought the easiest way would be to convert it to an array and evaluate the elements inside the array (This has been done successfully)...

The array has 8 columns and 100 rows. I want to evaluate the 2nd and 4th column in each row. If the value in the 2nd or 4th column is 1, display a msgbox (or something to indicate a 1 has been detected). This is all done with a button click in a form.



Code:

Private Sub Event_Click()
Dim file_name As String
Dim fnum As Integer
Dim whole_file As String
Dim lines As Variant
Dim one_line As Variant
Dim num_rows As Long
Dim num_cols As Long
Dim the_array() As String
Dim R As Long
Dim C As Long

    file_name = App.Path
    If Right$(file_name, 1) <> "\" Then file_name = file_name & "\"
    file_name = file_name & "file.csv"

    ' Load the file.
    fnum = FreeFile
    Open file_name For Input As fnum
    whole_file = Input$(LOF(fnum), #fnum)
    Close fnum

    ' Break the file into lines.
    lines = Split(whole_file, vbCrLf)

    ' Dimension the array.
    num_rows = UBound(lines)
    one_line = Split(lines(0), ",")
    num_cols = UBound(one_line)
    ReDim the_array(num_rows, num_cols)

    ' Copy the data into the array.
    For R = 0 To num_rows
        If Len(lines(R)) > 0 Then
            one_line = Split(lines(R), ",")
            For C = 0 To num_cols
                the_array(R, C) = one_line(C)
            Next C
        End If
    Next R

End Sub
