    Public Function OutPutCSV(ByVal FileName As String, ByVal DataTable As DataSet, Optional ByVal TableIndex As Integer = 0) As Boolean
        Dim fw As StreamWriter
        Dim myRow As DataRow
        Dim myCol As DataColumn
        Try
            fw = New StreamWriter(FileName, True)
            For Each myCol In DataTable.Tables(TableIndex).Columns
                If myCol Is DataTable.Tables(TableIndex).Columns(DataTable.Tables(TableIndex).Columns.Count - 1) Then
                    fw.WriteLine(myCol.Caption)
                Else
                    fw.Write(myCol.Caption)
                    fw.Write(",")
                End If
            Next myCol
            For Each myRow In DataTable.Tables(TableIndex).Rows
                For Each myCol In DataTable.Tables(TableIndex).Columns
                    If myCol Is DataTable.Tables(TableIndex).Columns(DataTable.Tables(TableIndex).Columns.Count - 1) Then
                        fw.WriteLine(myRow(myCol))
                    Else
                        fw.Write(myRow(myCol))
                        fw.Write(",")
                    End If
                Next myCol
            Next myRow
            Return True
        Catch e As Exception
            MessageBox.Show(e.Message, "", MessageBoxButtons.OK, MessageBoxIcon.Error)
