Hi all !! I have a problem with DLLs !! My 3DEngine has a few Global Variables. One of them is an instance to a class CRenderer !! CRenderer has all the member variables for DirectX and Direct3D (so the backbuffer, z-buffer, and so on) and functions to render my primitives such as walls, Meshes and stuff. In my file 3dengine.cpp this looks like: ... CRenderer Renderer; .... In the header 3dengine.h: .... extern CRenderer Renderer; .... Ok, so I can access Renderer from everywhere in my program if I include 3dengine.h !! This works very fine, however I have a problem. I know want to create a DLL which is Loaded with LoadLibrary. I call Functions of this DLL using GetProcAdress. I need to go this way (I cannot use the header and use a lib) !! Now, does anyone know how I can access this global variable Renderer from my DLL ??? If I put a extern CRenderer Renderer in my DLL, the compiler works fine, but the linker gives errors !! I don''t want to pass Pointers of these instances to my dll. Thanks very much for your help, Phillip

I''m afraid you''re stuck passing a pointer to your global variable to your DLL. The point behind a DLL is that it''s memory space independent, that is, it doesn''t and can''t know what is going on in the application that summons it, unless you tell it.
