The attached file is a copy of a file that I need to read into a datagridview.

What I need to do is skip the first 17 lines and then check if the UBOUND is > 2 and begin reading the file
and when the UBOUND < 2 to stop.

Thank you in advance.

   Public Sub ReadFile(ByVal fileName As String)

        Using reader As New TextFieldParser(fileName)

            reader.TextFieldType = FieldType.Delimited

            ' Set the delimiters for comma separated text
            reader.Delimiters = New String() {vbTab}

            Dim currentRow As String()
            Dim i As Integer

            'Loop through all of the fields in the file.
            'If any lines are corrupt, report an error and continue parsing.
            While Not reader.EndOfData
                Try
                    i = i + 1
                    currentRow = reader.ReadFields()
                    If (i > 17) And UBound(currentRow) > 2 Then
                        MsgBox(currentRow(0))
                    End If
                    ' Include code here to handle the row.
                Catch ex As MalformedLineException
                    MsgBox("Line " & ex.Message & " is invalid.  Skipping")

                End Try
            End While
        End Using

    End Sub

if this process is continuing in the same file you ahve to drive logic for this...
