Serialize EntitySet Through Net Remoting?
Jun 14, 2010I have a shared object through net remoting. The problem is that this object has some EntitySet and EntityRef attributes. When I try to run the program I get an exception telling me that EntitySet is not marked as Serializable. If I mark it as Serializable everything seems to be ok, but when I try to access from outsied to the attribute represented by the EntitySet, I am not able to use it.
BTW, Does anyone know how change the default binary serialization of tcp channel?
C# - .NET Remoting - How To Handle Disconnected Objects
Oct 26, 2010First, let me explain a little bit about my setup. My server is setup as a Marshaled singleton object:
RemotingServices.Marshal(lsServer, ServerObject.objectUri);
In order to have two-way communication from the server to the client, the client activates a ServerObject, then passes in its own ClientObject (which is also a MarshalByRefObject) the server uses the ClientObject to talk back to the client:
var lsClient = new ClientObject();
var lsServer = (ServerObject)Activator.GetObject(typeof(ServerObject), url);
lsServer.attach(lsClient);
When the attach method is called, the server takes the ClientObject and stores it in a List:
public void attach(ClientObject client) {
clientList.Add(client);
}
The server can then call a method on the ClientObject called "SendMessage" to communicate to each client in its list:
foreach(var c in clientList) {
c.SendMessage("Hello");
}
This works great until a client is encountered that has disconnected. In this case, an error is thrown about the client refusing the connection. I can catch the error, but the problem is I cannot remove the reference to the ClientObject from the server's List. The following re-throws the "connection refused" exception anytime a client has been disconnected:
clientList.Remove(badClient);
So a couple of questions:
1- Is there a way to detect the connection state of a client without having to catch an error?
2- When I do detect a client that has disconnected, why does the attempt to remove the object from the server's list appear to "communicate" with the client (thus causing the exception to be thrown again?)
EDIT
As Patrick pointed out below, doing a Remove from a list causes the List to iterate my objects and do a comparison on them (calling .Equals) - this is what caused my ClientObject to attempt to communicate again and thus throw the exception. To resolve it, I instead changed the List to a dictionary keyed off a unique ID supplied by my Client at the time of attaching to the server. Then I used that unique ID to remove the client. I never did find a direct way for determining if a client had disconnected other than catching the error.
Web Forms :: How To Retrieve Data From Dataset With Remoting
Mar 16, 2010I'm building a Remoting Demo, and here's my scenario:
There are 4 projects:
ServicedCOM: This project I've built a ServicedComponent, this component using for access data from database.
RemoteLoader: I using this to load ServicedCOM to RemotingServer.
RemotingServer: This is an console application, and this application can be running from another computer.
WebApp: Client, this is inteface using for End User.
and my results: I can access and retrieve data with function is called SpeakHello (test function), but I cannot do the same thing to get sectors using this model, I think I'm doing something wrong. and here's my code snippet:
1. I have a ServicedCOM and a function to get Sectors is called GetSectors (I test OK)
[Code]....
[Code]....
2. I have a Remote loader
[Code]....
3. And here's RemotingServer
[Code]....
4. And the last is Client

WebMatrix :: Deploying The Mvc2.0 Project To Remoting Host?
Jul 14, 2010I'm so excited about the webmatrix, because it makes all the works to be easier than ever before, so I make a try, but I met a problem when I deployed the project membership db to remoting host (I chose the cytanium.com), and I had deployed the project files and another database sucessfully, only the membership related database failed, the error message is below:
[Code]....
I thought that the problem source is about the collation of the database, so I change my database collation from "Chinese_PRC_CI_AS" to "SQL_Latin1_General_CP1_CI_AS", but the problem is the same, I had search a lot of articles, but I didn't find a way to resolve this issue.
What Is The Default Connection Limit Of .Net Remoting Http Channel
Jun 13, 2010When using .net remoting, does the server limit incoming client remoting calls?
I find a particular remoting call (during ASP.NET page rendering) to take from 200ms to 1500ms. While the underlying data call is only 50ms. Factoring in remoting overhead of 150ms per call, the only difference between the two cases is that the latter scenario has about a dozen more parallel remoting calls in progress. So my guess is that when too many remoting calls are happening, some will get queued up? I also doubt system resource is the cause of the delay because it is not nearly saturated.
Searching MSDN, I find the below:
http://msdn.microsoft.com/en-us/library/ms973907.aspx
clientConnectionLimit: specifies how
many connections can be simultaneously
opened to a given server. The default
is 2. This is exactly the same as the
connection limit on ServicePoint in
the net classes.
That seems awfully low to me and if were the case, my app's performance would have been much worse. Can someone confirm if there is indeed a connection limit or some other throttling in .net remoting?

View 2 RepliesHow To Ensure User Accepts Terms And Conditions On Website
Jan 21, 2010We're modifying an existing ASP.NET application. We added a Terms and Conditions page with an "Accept" button that stores that choice in the user's account data. We want to prevent the user from accessing any page when the user has not accepted the Terms and Conditions.
I think we want to do this by looking up the "accepted terms" value upon login and storing it in the session. Then we need to intercept every request and check for that session value. (If it's not there, we redirect the user to the Terms and Conditions page.)
Is the PreRequestHandlerExecute method the right place to put this check? This method also gets called on requests for stylesheets and images, so it doesn't seem like it was intended for this purpose.

Asp.net - Can Webservices As Singltons With Different Users?
Jun 23, 2010I am developing an ecommerce app that is using the UPS shipping webservice. I have read that it is good to create a singleton so there is only one instance of a webservice at any time. My code for that is below.
[code]...
In the line above in the construtor I have to set the UPSSecurityValue of the service. Then later I will call the ProcessShipment function. My question is; Since the webservice is being traeted as a singlton could different instances of the app share that same UPSSecurityValue and could it change between when I set it and when I call ProcessShipment?
