Hi all

I am building a plugin application. My application is
required to search for new pluggins within a predefined
directory and invoke it by creating a new instance of what
ever the pluggin is and bring up the main form associated
with that particular plugin. How would I do that?

I have checked up something call appdomain, not totally
sure how to use it. Is there any resources that i may be
able to look up on? or am i on the right track at all?
There are all these methods called CreateInstance,
CreateInstanceAndUnwrap, CreateInstanceFromAndUnwrap,
what's the difference between all these?

thanx

James
