Forums Scripts & Popups Simplest way to communicate with another appl.?

Er, hello. I'm hammering out an application in C# to essentially act as a bot, and I'm wondering, what would be the best way to send any and all text output from mIRC to it for processing?

Fair warning, I am completely inexperienced in mIRC scripting, and almost completely so in programming in general - this is my learn-by-doing project, so feel free to assume you need to spell things out for my ignert self to understand. So far I've resorted to monitoring and reading log files - probably one of the worst available ways to do it.
