If i have an executable which loads a DLL, is it then possible that the executable can call functions from the DLL eventhough it doesn't know what functions exist in that DLL ??

The executable will act like an online server which can receive commands remotely from anyone that connects to it. When the executable receives a command like "nickname" it should call the function 'nickname()' from the DLL.

But i want to do it in a way so that when i update the DLL with new functions, that i don't have to update to exe file aswell with the new function names that the DLL has.

So is there a way to make the executable look/scan for a function inside my DLL, and if it's there execute that function??
