Event handling between process.

[archana]

Hi all,

I want to do inter process communication in c#.

I am having one application and one dll. What i want is load that dll
at runtime. After loading that dll i want to send one event from
application which should get trapped in dll. And only after dll has
completed that event i want my application to continue with next code.
Here i also want to use shared memory between application and process.

I am new to inter process communication. If i am wrong please correct
me.

thanks in advance.

Hi,

Have you considered .NET Remoting yet?

It's not entirely clear what you are after, a dll once loaded in a process becomes an
integral part of it, that is, dll's are no stand-alone run-time entities and they are no
means for inter-process communication.
Inter process communication is about interaction between two or more processes, these
processes can use a number of available low-level technologies like sockets , named pipes,
shared memory, RPC's, DCOM etc. as an interprocess communication path. .NET wraps most of
these technologies in the System.Remoting (V2) and WCF (V3) namespace classes.

Hi

thanks for your rply.

Yes i read about .net remoting but i don't want client and server
concept. as my both application and dll will be on same pc.

so can i do this without remoting.

thanks in advance,

No, you can't without any form of inter-process channel (sockets, pipes, shared
memory.....). As I said in another reply, a dll becomes a part of the application code and
data, both processes get their private view mapped in their own process space.
What you need is a way to call functions across process boundaries (what you call event
handling), and this is exactly what Remoting is about.
