Finding all active X dlls in a directory and using them

I'm trying to create a sort of loadable module scheme for an application I am developing at the moment.

The way I want it to work is that the use places these dlls in the same directory as the exe file. The exe file will then scan the directory for the dlls and register them.

So to do that I could just use regsvr32 with all *.dll files in the directory. But then how do i reference a function from that dll from my application. ?!?

I hope you understand what i'm meaning.

Drop me a line if you need more info.
