I’m Trying to to rename file image after export with datatable in VB.NET

I use library control LabelControl for .NET from BaiqiSoft

I have also asked Baiqisoft support and then he replied “this is the design behavior of our product.” so the results of the export filename from the library are sequential .is there a solution I can rename after export image and also without mistakes I rename the filename based on expression datatable ?

Please Guide me

for more detailed documentation refer below link.

Imports System.IO
Imports BaiqiSoft.LabelControl
Public Class Form1
    Private m_DataTable As DataTable
    Private Sub CreateDataTable()
        If m_DataTable IsNot Nothing Then Return
        m_DataTable = New DataTable
        'Columns
        m_DataTable.Columns.Add("ProductName", GetType(String))
        m_DataTable.Columns.Add("Barcode", GetType(String))
        m_DataTable.Columns.Add("Price", GetType(Single))
        m_DataTable.Columns.Add("LabelNumber", GetType(Integer))
        m_DataTable.Columns.Add("QTY", GetType(Integer))
        m_DataTable.Columns.Add("Filename", GetType(String), "ProductName +','+ Barcode")
        'Rows
        m_DataTable.Rows.Add("Mishi Kobe Niku", "845723054943", 96.0, 2, 1)
        m_DataTable.Rows.Add("Carnarvon Tigers", "246321456231", 61.5, 1, 1)
        m_DataTable.Rows.Add("Ipoh Coffee", "589412354786", 46.0, 3, 1)
        m_DataTable.Rows.Add("Aniseed Syrup", "457125463254", 10.0, 1, 1)
        m_DataTable.Rows.Add("Teatime Chocolate Biscuits", "232145674321", 9.2, 5, 1)
    End Sub
Private Sub Btnexport_Click(sender As Object, e As EventArgs) Handles Btnexport.Click
        Dim theLabel As New LabelPrinting()
        theLabel.LicenseKey = ""
        theLabel.OpenLabel(Application.StartupPath & "test.blf")
        Dim selectedRows As DataTable = m_DataTable.Clone
        selectedRows.Columns("Filename").Expression = Nothing : selectedRows.Columns("Filename").ReadOnly = False
        For Each row2 As DataGridViewRow In DataGridView1.Rows
            Dim isselect As Boolean = Convert.ToBoolean(row2.Cells("checkboxcolumn").Value)
            If isselect Then
                Dim newRow As DataRow = selectedRows.NewRow()
                newRow("ProductName") = m_DataTable.Rows(row2.Index)("ProductName")
                newRow("Barcode") = m_DataTable.Rows(row2.Index)("Barcode")
                newRow("Price") = m_DataTable.Rows(row2.Index)("Price")
                newRow("LabelNumber") = m_DataTable.Rows(row2.Index)("LabelNumber")
                newRow("QTY") = m_DataTable.Rows(row2.Index)("QTY")
                newRow("Filename") = m_DataTable.Rows(row2.Index)("ProductName") + "," + m_DataTable.Rows(row2.Index)("Barcode") + ".png"
                selectedRows.Rows.Add(newRow)
                theLabel.Label.QuantityColumn = "QTY"
            End If
        Next row2
        theLabel.DataSource = selectedRows
        theLabel.ExportOptions.FileName = "test"
        theLabel.ExportOptions.Path = Application.StartupPath
        theLabel.ExportOptions.Quantity = QuantityOptions.AllRecords
        theLabel.ExportOptions.Format = ImageFormats.Png
        theLabel.ExportOptions.Resolution = 300
        theLabel.ExportImage()
    End Sub
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        CreateDataTable()
        DataGridView1.DataSource = m_DataTable
        Dim CheckedBoxColumn As New DataGridViewCheckBoxColumn
        CheckedBoxColumn.Width = 40
        CheckedBoxColumn.Name = "checkboxcolumn"
        CheckedBoxColumn.HeaderText = "Check"
        DataGridView1.Columns.Insert(0, CheckedBoxColumn)
    End Sub
End Class

Result from Code :

test1.png

test2.png

test3.png

test4.png

test5.png

It should be like this (Desired result):

Mishi Kobe Niku,845723054943.png
 
Carnarvon Tigers,246321456231.png
 
Ipoh Coffee,589412354786.png
 
Aniseed Syrup,457125463254.png
 
Teatime Chocolate Biscuits,232145674321.png

Is it possible that I can rename like this

test1.png >>>> Mishi Kobe Niku,845723054943.png

test2.png >>>> Carnarvon Tigers,246321456231.png

test3.png >>>> Ipoh Coffee,589412354786.png

test4.png >>>> Aniseed Syrup,457125463254.png

test5.png >>>> Teatime Chocolate Biscuits,232145674321.png
