in fact I DO want to be able to call gui-interfacing functions of the form.
As Henry states, doing GUI calls from a thread is easy by Application.QueueAsyncCall().
But, AFAIK, the dll does not know the main Form instance and does not know the Application instance of the application that loads the dll.
Moreover the memory management of the dll is independent of that of the Application it is called by. That is why you can't easily pass objects and strings between an application and the dll.
AFAIK, there are means to unify the memory management and to make the Form and/or the Application known to the dll.
But these issues need to be soled independently from the fact that the dll calls another dll.
