What in particular are you wanting to access from StarCraft with mIRC. StarCraft has quite a few pages, and it would help if you could supply the web address of the page that you want to access along with an example of the type of information you want to relay from StarCraft to mIRC.
I'm pretty sure he means to have mIRC connect within the game itself, as Starcraft has a chat feature built in. Though everything is possible, it would be neither feasable nor practical.
Well. At least I won lunch. Good philosophy, see good in bad, I like!
