and for downloading from server to client , to open dialog you can do something like this


                        Response.Clear()
                        Response.ContentType = "application/octet-stream"
                        Response.AddHeader("Content-Disposition", _
                          "attachment; filename=""" & filename & """")
                        Response.Flush()
                        Response.WriteFile(filepath)

Sub DisplayDownloadDialog(ByVal PathVirtual As String)
        Dim strPhysicalPath
        Dim objFileInfo As System.IO.FileInfo
        Dim strFileName As String = "C:\Inetpub\wwwroot\Mercator\" + FileNameCSV
        Try
            strPhysicalPath = Server.MapPath(FileNameCSV)
            'exit if file does not exist
            If Not System.IO.File.Exists(strPhysicalPath) _
                 Then Exit Sub
            objFileInfo = New System.IO.FileInfo(strPhysicalPath)
            Response.Clear()
            'Add Headers to enable dialog display
            Response.AddHeader("Content-Disposition", "attachment; filename=" & _
                objFileInfo.Name)
            Response.AddHeader("Content-Length", objFileInfo.Length.ToString())
            Response.ContentType = "application/octet-stream"
            Response.WriteFile(objFileInfo.FullName)
        Catch
        Finally
            Response.End()
        End Try
    End Sub


Call the above procedure and give the full path name of the file to be saved when calling it as shown below and make sure the path given exists on your machine. In my example I have a folder Billing in C:\Inetpub\wwwroot\Mercator


Dim FileNameCSV As String = "C:\Inetpub\wwwroot\Mercator\Billing\Billing-" &  ".csv"
DisplayDownloadDialog(FileNameCSV)

This should be working.
