Dim csv As New Chilkat.Csv

' Prior to loading the CSV file, indicate that the 1st row
' should be treated as column names:
csv.HasColumnNames = True

' Load the CSV records from the file:
Dim success As Boolean
success = csv.LoadFile("sample.csv")
If (success <> True) Then
    Debug.WriteLine(csv.LastErrorText)
    Exit Sub
End If


' Display the column names:
Dim i As Integer
Dim colName As String
Dim idx As Integer
For i = 0 To csv.NumColumns - 1
    colName = csv.GetColumnName(i)
    Debug.WriteLine(i & ": " & colName)

    ' The following line demonstrates to to get the column
    ' index given a column name:
    idx = csv.GetIndex(colName)
    Debug.WriteLine(colName & " is at column index " & idx)
