Help how to get the list of printer in the client computer

[C Coudou]

Hi mates, I have a program in asp.net which will print a report viewer to the default printer. When the user clicked the print button. It will automatically print to default printer. I'm using the System.Drawing.Printing.PrinterSettings for getting the default printer. Here's the snippet code:

Protected Sub btnPrint_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPrint.Click
Try
Dim rptViewer As ReportViewer

        rptViewer = New ReportViewer
        With rptViewer.LocalReport
            .DataSources.Clear()
            .ReportPath = Server.MapPath("rptCert.rdlc") '(IM USING RDLC INSTEAD OF CR)
            .DataSources.Add(dataSource)
            .Refresh()
        End With

        myRPT= New CustPrint
        With myRPT
            .Export(rptViewer.LocalReport)
            .m\_currentPageIndex = 0
            .Print()
        End With
    Catch ex As Exception
        log.Debug(ex.ToString)
    End Try

End Sub
----CLASS-----

Public Class CustPrint
' Implements IDisposable

Public m\_currentPageIndex As Integer
Public m\_streams As IList(Of Stream)
Public stName As String
'create steam
Public Function CreateStream(ByVal name As String, ByVal fileNameExtension As String, \_
   ByVal encoding As Encoding, ByVal mimeType As String, ByVal willSeek As Boolean) As Stream

    Dim stream As Stream = New FileStream("C:\\" + name + "." + fileNameExtension, FileMode.Create)
    m\_streams.Add(stream)
    Return stream

End Function
'Export
Public Sub Export(ByVal report As LocalReport)

    Try
        Dim deviceInfo As String = \_
    "<DeviceInfo>" + \_
    "  <OutputFormat>EMF</OutputFormat>" + \_
    "  <PageWidth>8.5in</PageWidth>" + \_
    "  <PageHeight>11in</PageHeight>" + \_
    "  <MarginTop>0.25in</MarginTop>" + \_
    "  <MarginLeft>0.25in</MarginLeft>" + \_
    "  <MarginRight>0.25in</MarginRight>" + \_
    "  <MarginBottom>0.25in</MarginBottom>" + \_
    "</DeviceInfo>"

        Dim warnings() As Warning = Nothing
        m\_streams = New List(Of Stream)()

        report.Render("Image", deviceInfo, AddressOf CreateStream, warnings)

        Dim stream As Stream
        For Each stream In m\_streams
            stream.

That isn't how asp.net works. As you have discovered code-behind runs on the server not the client. The only way to use a client resouce such as a printer is to use ActiveX which is troublesome at best.

i've searched on google with ActiveX and i found a code which will get the printers of server or client which is good.like this var server="10.1.254.222"; 'change to client ip var shell = new ActiveXObject("wscript.shell"); var result = shell.Exec("net view \\\\" + server).StdOut.ReadAll(); var line = new Array(); ... and so on. but the problem of the above code will get the list of printers which are shared.

C# コードMicrosoft End User 2000-2008 「「「「「「「「「「「「「「「「「「「「「「「「「「「「 The best things in life are free 」」」」」」」」」」」」」」」」」」」」」」」」」」」」

It is generalyy a bad idea to use ActiveX control, they are difficult, cumbersome and prone to security issues. Users can disable them and admins can restritct them. They are also only usable in IE. Make the report available and let the use choose which printer.
