我正在使用该项目作为创建Web应用程序的基础，以使条形码号码加上我的服务器设置为低安全级别，并且我无法更改它，我想到使用asp.net沙箱无法结束，

如果需要，我可以发布更改的代码并完成！

谢谢您的关注

I''m using the project as a basis to create a web application to make the bar code number in plus my server is set to the low security level and I can not change it, I thought about using asp.net sandbox could not over,

If needed I can post the code with the changes and did!

Thank you for your attention

我正在使用的其余代码！

the rest of the code I''m using!

Private Sub carregaimagembarras()
        Dim Bitmapcaminhoimagem As String = imagebarcode.ImageUrl  ' carrega a imgem na variavel
        Dim originalImage As New System.Drawing.Bitmap(Server.MapPath(Bitmapcaminhoimagem)) ' converte a imagem em System.Drawing.Bitmap
        If Not Me.imagebarcode.ImageUrl Is Nothing Then
            Dim barcodes As New System.Collections.ArrayList
            Dim dtStart As DateTime = DateTime.Now
            Dim iScans As Integer = 100
            BarcodeScanner.FullScanPage(barcodes, originalImage, iScans, BarcodeScanner.BarcodeType.All)
            ' Show the results in a message box

            ShowResults(dtStart, iScans, barcodes)

        End If
    End Sub
    Private Sub ShowResults(ByVal dtStart As DateTime, ByVal iScans As Integer, ByRef barcodes As System.Collections.ArrayList)
        Dim message As String = ""
        If barcodes.Count > 0 Then
            Dim bc As Object
            For Each bc In barcodes
                Message += bc & vbNewLine
            Next
        Else
            Message += "Failed to find a barcode."
        End If
        txtcodigobarras.Text = Message
        End Sub

早上好！我不是要实现解决方案，就是要转换条形码图像的数量，接受类似项目的建议，因为我们的同事的帮助是最初的项目开发人员桌面，由于安全问题，我无法调整网络.
我想帮助另一个项目条形码vb asp.net网站的链接.

谢谢，也谢谢您的关注.

Good morning! I''m not managing to implement solution is to transform bar code image in number, accepted suggestions for similar projects as the help of our colleague was the initial project developer desktop and I can not adptar the web due to security issues.
I would like to help with the link from another project barcode vb asp.net web.

Thank you and I thank you for your attention.
