Can you explain in detail what type of messages you want to send?

What you want to google is "C# interprocess communications". There are several ways to accomplish this (remoting, WCF, TCP/IP lister, and there's even a message called WM_BROADCAST (or something like that).

Which method you choose is based on the program's intended use and the topology on which it is used.

Solution 4

depending on your setup you can use WCF or even message queues. look at sql message queues they are light and work across many things. Also are your two applications on the same computer?

Solution 1

It really depends on what you're trying to achieve. One way to do this would be to implement the C++ application as a COM Server, and interact with it through COM Interop. Another mechanism would be to open up a TCP channel in the C++ application, and control it via that.
