Controlling a DLL/EXE from another program

[Mark Newman]

Anyone have a good way to control an standalone EXE or a DLL from another
program? This program, which performs low-level port I/O, would be launched
from the parent app and keep running, responding to a few simple commands
from the parent, such as "Start", "Stop", "Set Parameter X to 1" and of
course "Terminate".

I've considered defining some custom Windows messages, using a shared memory
location, or even a simple disk file.

Any ideas?

Thanks!

Using custom messages is a traditional and effective approach. It has the advantage over using shared memory or disk files in that there are no issues about access conflicts (it's friendly to multi-tasking and multi-threading).
