Re: A89: installing C Event Hooks + misc other...


Event hooks are sort of my specialty.  I've written complete, bestview, 
and faster.  I do them in assembly.  What you need to do is go to and get the onkey express 
which will show you how to do tsr installation in c.

If you follow the conventions that have been establised by kevin Kofler 
you will not need to worry about uninstallation.  You should also go to 
his website at:
