I catch an exception, I use Windows Service, CSLA 2.0.2, Remoting Portal. How I do? Please help me!
Because of security restrictions, the type Csla.Server.DataPortalContext cannot be accessed.

Hi,
We use a Windows Service for remoting, too. In the OnStart-method of our service we configure remoting this way:
RemotingConfiguration.CustomErrorsMode = CustomErrorsModes.Off
Dim properties As New Hashtable
properties("name") = "MyChannel"
properties("port") = TcpPort ' TpcPort goes here
Dim serverFormatter As New BinaryServerFormatterSinkProvider
serverFormatter.TypeFilterLevel = Runtime.Serialization.Formatters.TypeFilterLevel.Full
Dim channel As New TcpServerChannel(properties, serverFormatter)
ChannelServices.RegisterChannel(channel)
RemotingConfiguration.RegisterWellKnownServiceType(GetType(Csla.Server.Hosts.RemotingPortal), "MyService", WellKnownObjectMode.SingleCall)
Hope this helps,
Christian
Thanks for your rely!
I used your method and my program has not raise an exception. But it suspend and not return anything![Sad [:(]](/emoticons/emotion-6.gif)
Could you explain for me more detail
I created a Windows Service project and added a reference to the Csla.dll and to my business dll. Then I overrode the OnStart-method of the Windows Service:
Protected Overrides Sub OnStart(ByVal args() As String)
RemotingConfiguration.CustomErrorsMode = CustomErrorsModes.Off
Dim properties As New Hashtable
properties("name") = "MyChannel"
properties("port") = 54321
Dim serverFormatter As New BinaryServerFormatterSinkProvider
serverFormatter.TypeFilterLevel = Runtime.Serialization.Formatters.TypeFilterLevel.Full
Dim channel As New TcpServerChannel(properties, serverFormatter)
ChannelServices.RegisterChannel(channel)
RemotingConfiguration.RegisterWellKnownServiceType(GetType(Csla.Server.Hosts.RemotingPortal), "MyService", WellKnownObjectMode.SingleCall)
End Sub
Of course you should use a better channel name than “MyChannel” and a better service name than “MyService”, shouldn't use this port number and should write some code for error handling.
I installed the service with the install utility:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\InstallUtil RemoteService.exe
and
NET START "MyService"
My client application’s config file looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key ="CslaAuthentication" value ="Csla"/>
<add key ="CslaDataPortalProxy" value ="Csla.DataPortalClient.RemotingProxy, Csla" />
<add key ="CslaDataPortalUrl" value ="tcp://servername:54321/MyService" />
</appSettings>
</configuration>
Please make sure that you use the same tcp port number and service name on service side and application side.
Greetings,
Christian
Thanks Massong for your rely.
I had code, but have an error at
return portal.Create(objectType, criteria, context);
Cannot evaluate expression because a native frame is on top of the call stack.
Hi phucphlq,
This doesn’t seem to be a problem with the Windows Service. The call of the Create-method is a little bit strange to me. Your business object’s factory method should look like this (see page 78 of Rocky’s VB-Book):
Public Shared Function NewEmployee(context as Context) As Employee
Return DataPortal.Create(Of Employee)(New Criteria(context))
End Function
And your DataPortal_Create method should look like this (page 425):
Private Overloads Sub DataPortal_Create(ByVal criteria As Criteria)
...
End Sub
For testing you could try to run the ProjectTracker example in a Windows Service.
Christian,
It looks like this may be just what we needed... thanks a bunch!
James
Hi all!
How to config in App.config and not write code at Service.
Thanks
