Like many on here, I am new to programming and mainly focus on web development. I have written a program cobbled together from help on here that works perfectly. I take a CSV file and inject it into an SQL database. I am getting a "MalformedLineException" line exception on the last line of the CSV file and believe it is because the header line is not being skipped.
Would love some help on working out how to skip the first line from my code below:
Private Sub subProcessFile(ByVal strFileName As String)
'This is the file location for the CSV File
Using TextFileReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(strFileName)
'removing the delimiter
TextFileReader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited
TextFileReader.SetDelimiters(",")
ProgressBar1.Value = 0
Application.DoEvents()
'variables
Dim TextFileTable As DataTable = Nothing
Dim Column As DataColumn
Dim Row As DataRow
Dim UpperBound As Int32
Dim ColumnCount As Int32
Dim CurrentRow As String()
'Loop To read in data from CSV
While Not TextFileReader.EndOfData
Try
CurrentRow = TextFileReader.ReadFields()
If Not CurrentRow Is Nothing Then
''# Check if DataTable has been created
If TextFileTable Is Nothing Then
TextFileTable = New DataTable("TextFileTable")
''# Get number of columns
UpperBound = CurrentRow.GetUpperBound(0)
''# Create new DataTable
For ColumnCount = 0 To UpperBound
Column = New DataColumn()
Column.DataType = System.Type.GetType("System.String")
Column.ColumnName = "Column" & ColumnCount
Column.Caption = "Column" & ColumnCount
Column.ReadOnly = True
Column.Unique = False
TextFileTable.Columns.Add(Column)
ProgressBar1.Value = 25
Application.DoEvents()
Next
clsDeletePipeLineData.main()
End If
Row = TextFileTable.NewRow
'Dim Rownum As Double = Row
'If Rownum >= 1715 Then
' MsgBox(Row)
'End If
For ColumnCount = 0 To UpperBound
Row("Column" & ColumnCount) = CurrentRow(ColumnCount).ToString
Next
TextFileTable.Rows.Add(Row)
clsInsertPipeLineData.main(CurrentRow(0).ToString, CurrentRow(1).ToString, CurrentRow(2).ToString, CurrentRow(3).ToString, CurrentRow(4).ToString, CurrentRow(5).ToString, CurrentRow(6).ToString, CurrentRow(7).ToString, CurrentRow(9).ToString)
ProgressBar1.Value = 50
Application.DoEvents()
End If
Catch ex As _
Microsoft.VisualBasic.FileIO.MalformedLineException
MsgBox("Line " & ex.Message &
"is not valid and will be skipped.")
End Try
End While
ProgressBar1.Value = 100
Application.DoEvents()
clsMailConfirmation.main()
TextFileReader.Dispose()
MessageBox.Show("The process has been completed successfully")
End Using

"MalformedLineException" says that Line cannot be parsed using the current Delimiters, to fix it, adjust Delimiters so the line can be parsed correctly, or insert exception-handling code in order to handle the line. Someone encountered similar question, maybe its reply can help you.
