I see this is a pretty old post, hope you guys are still around lol. I've been using this code and it works great for sending strings to a mirc message window. I'm trying to figure out if there is a way to send a key using this code? Like just sending the ESCAPE key.

mIRCObject.SendMessage(708, WOULDLIKEESCAPEKEYHERE, mIRC.Messaging.EvaluationMethods.Evaluate)

any help would be great!
