I'm using c# to design a client-server application. I'm still a beginner, and am learning the ropes of c# and OO. Right now, I wrote on a piece of paper a few ideas. Essentially, I would create a class "client", which contains all the details (sockets, etc). The client class would be created and stored in an array which would be used...

I'm in a Math class about coding theory and we have to do a project for our term mark. My project is a client with an echo server, which shows what errors were introduced in the trip from the client to the server, and then back.

Let's say i'm building a client server software. the main server connects to agents on different servers. the agents is a search client and each will return quite huge array of 64bit integers and finally the main server (parent) will sort it to produce finaly result. Which is better/faster approach, using a socket to get all the data...

Having not used MSMQ before, I'm not at all clear an the client environment requirements to use it. I'm designing a client/server solution that will integrate with a legacy system and I'm sold on messaging. I'd like to use a service bus implementation like MassTransit, but that requires MSMQ. Do I have to ensure that every client PC ha...

Say a server stores objects with a reference count. Clients, when they connect (over sockets), send messages to increment and decrement the counts on those objects. The only behavior pattern that's guaranteed is that if a client works with a particular object, it will increment it, some time will pass, and it will decrement it (clients n...
