Solution 1

Look at setting up a Socket [^]connection between the two. The link includes an example.

is there any other way of passing values instead of sockets?

OriginalGriff 17-Jul-11 4:06am

There are, but generally they are more complex, not less!
You could implement the TCPListener on which sockets is based, but trust me, Sockets is a lot easier!
You are trying to do something quite complex in actual fact - communicate between two end points over an already existing communications network - so you have to "fit in" with everything else that is going on on that network. Sockets are a nice, easy way to do that.

Well no, how are they supposed to know that the other one exists! Don't be last, sockets are not hard to grasp and that is a good example to get you started.

what about the remote calling methods like webservices,WCF etc?what are your suggestions about them?

Philippe Mori 17-Jul-11 19:10pm

Well, sockets might be easier to use for simple communications. But other technologies might be more appropriate to exchange complex data or when you want to essentially "calls" functions at the other hand.

In short, I would say the more complex the problem is, the more it will worth the effort to learn web services, WCF etc...

Not quite agree. Connection with self-hosted WCF and Service contract with one simple method can be easier. From the other hand, I faced with more complex problems requiring much more flexibility where WCF solution was impossible or too difficult, while TcpListener/TcpClient level did all the trick without any problems. And this is not untypical at all: high-level solutions are good for doing standard chores, tricky problems require lower level.

My 5. Not quite agree with the level of communication to use. 1) TcpListener/TcpClient makes it easier, 2) classical remoting needs more reading but actual solution looks simple, same about WCF. So, it depends what do you mean by "easy". I agree that if it includes learning, TCP level (sockets or TcpListener/TcpClient) can be the best. Also, this experience will never hurt.
