Oh, Also, IDEmIRC 1.1 (find it on
www.mircscripts.org) contains a small tool (DDECommander.exe) that allows you to pass commands to mIRC from the command line, if in a somehwat roundabout way - you have a problem though, I haven't released version 1.1 yet - but your merely hours away. The version in 1.0 you have to still play with the GUI which you definately don't want.
Does the same thing essentially as shellDDE does, except its prolly a little less confusing. Maybe.
