Quickly send an interprocess signal

Question

I want to send a signal from a C++ application to a C# application. This is only to let the C# program know the other one is running. I already use C# but I'm not really good at C++ yet. Do I have to create pipes or is there a quicker and/or easier way to do this?

Answer 1

IPC is easy using the classic WM_COPYDATA. A good example can be found here .
