Add Plug-Ins to your applications!!!

I know this is a zip, but if you like it, come back and VOTE! This is a simple project to show you how to add plug-ins to your apps. What do I mean by plug-ins? I mean the ability for your program to add unlimited functionality by the addition of DLLs or ActiveX exe's AFTER COMPILE. You can have a completely compiled application that simply takes a new DLL and makes it a part of itself. Why should you use it? Think of a large database application. You sell this to many users, and they all have legacy data to deal with, so you sell each of the a custom built plug-in that will convert all of thier old data. Or, if they have a custom app of thier own and they want a function that will automatically update info from thier database to yours, you could write a plugin. The possibilities are limitless, so here's the code!
