Exchange Messages between Winform (socket server) and Silverlight (socket client)

Question

Hi,

Does anyone know what's the best solution for this requirement, "Exchange Messages between Winform (socket server) and Silverlight Business Application (socket client)".

 

Business case is; I have a sensor which requires winform to listen events from serial port and I have a silverlight business application (right now this is pulling data from server at every two seconds). I would like to integrate this two separate applications to talk each other via socket.

 

Now, the main problem is I am having an 4004 error whenever I run silverlight application after I have added a socketclient class. The error message is "Unhandled exception ('Unhandled Error in Silverlight Application code: 4004. Message : System.ServiceModel.DomainServices.Client.DomainOperationException:')".

 

Is there anyone out there having the same problem as mine? :(

Answer 1

I have made the application work, the previous error was due to Database Server Not starting.

 

Now, I can manage to run the silverlight application. Now I have a problem with connecting to server due to this error "An attempt was made to access a socket in a way forbidden by its access permissions"

 

IP address is "127.0.0.1", port number is "4510".

 

Socket Server is Winform application.

Socket Client is Silverlight application (when I try to connect via winform client, everything is fine)

 

Does anyone know how to solve this problem?
