Error when tryinmg to Read RDLC from Server side

[Darren Hunnter]

Hi,

I have an issue, if I am trying to read an RDLC to a byte array through a domain service and then convert the bytes back to a stream I am getting an error saying it can't find part of the report. But if I reference the report directly in the silver-light per the example it works.

Here is the code:

Option Compare Binary
Option Infer On
Option Strict On
Option Explicit On
 
Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.ComponentModel.DataAnnotations
Imports System.Linq
Imports System.ServiceModel.DomainServices.Hosting
Imports System.ServiceModel.DomainServices.Server
Imports System.IO
Imports FileFunctions.FileFunctions
'TODO: Create methods containing your application logic.
<EnableClientAccess()>  _
Public Class TestReportServer
    Inherits DomainService
 
    Private Function GetServerRootPath() As String
        Dim r As String = HttpContext.Current.Server.MapPath("..")
        If r.EndsWith("\") = False Then r &= "\"
        Return r
    End Function
 
 
    <Invoke()>
    Public Function ReportTest() As String
        Dim r As String = GetServerRootPath() & "Reports\TestReport1.rdlc"
        Return r
    End Function
 
 
    <Invoke()>
    Public Function Getreport() As Byte()
        Dim b As Byte()
        Dim ff As New FileFunctions.FileFunctions
        b = ff.ReadFileToByte(GetServerRootPath() & "Reports\TestReport1.rdlc")
        Return b
    End Function
 
End Class


Imports System.ServiceModel.DomainServices.Client
Imports System.IO
 
Partial Public Class MainPage
    Inherits UserControl
 
    Dim test As New ReportApp.ReportTest.TestReportServer
 
 
    Public Sub New()
        InitializeComponent()
    End Sub
 
    Private Sub MainPage_Loaded(sender As Object, e As System.Windows.RoutedEventArgs) Handles Me.Loaded
        'test.ReportTest(AddressOf GetTest, Nothing)
        test.Getreport(AddressOf DisplayReort, Nothing)
 
 
       
    End Sub
 
    Private Sub GetTest(e As InvokeOperation(Of String))
        MessageBox.Show(e.Value)
    End Sub
 
    Private Sub DisplayReort(e As InvokeOperation(Of Byte()))
        Dim b As Byte()
 
        b = e.Value
 
 
 
        'MessageBox.Show(b.Length.ToString)
        's.Write(b, 0, b.Length)
 
        'MessageBox.Show(s.Length.ToString)
 
        's = Application.GetResourceStream(New Uri("BarChartDemo;component/TestReport1.rdlc", UriKind.Relative)).Stream
 
        Dim rdlStream As Stream = Application.GetResourceStream(New Uri("ReportApp;component/TestReport1.rdlc", UriKind.Relative)).Stream
        Dim rdlstream1 As Stream
 
        rdlstream1 = New MemoryStream()
        rdlstream1.Write(b, 0, b.Length)
 
 
        Try
            ReportViewer1.LoadReport(rdlStream)
        Catch ex As Exception
            MessageBox.Show(ex.ToString)
        End Try
 
        ReportViewer1.RefreshReport()
 
        'MessageBox.Show(b.Length)
    End Sub
 

Is there any diffrence between stream and  Application.GetResourceStream in there encoding.

I would like to keep the RDLC files on the server and read them in as a byte array and then reconstitute the stream. 

Any help would be appreciated.
