Got a real pain of a problem. Im using vb.net to write a dll for third party software (PreS) that has no COM interface but allows functionality to call DLL's. But it requires an entry point of UserInstruction. I have been doing some research and have found seen many threads saying that exporting functions isn't avaliable in framework. Wandered weather there is an add on or some work around no matter how complicated it maybe. Any help will be greatly appreciated.
