How to communicaton between two applications

[George Chen]

Hi

I have lots applications are already written by C++. It 's easy to use
PostMessage in one application and catch this message in another
application's WndProc Function.
Since .net have some powerful library. I use C# to develop new
application. But I do not know how to using simlar function in C# to
communication to my exist C++ application.
Any help would be appreciate.

You can override the Form's WndProc to recieve and use API calls
(SendMessage) to send messages
check http://pinvoke.net to see how to import WinAPI calls to C# code.
Another solution is .NET remoting, which is preferable when communicating
between two .NET applications.
