Hey. I know that if I include resources in a DLL, I won''t have to re-build them every time I modify my code. I tried making a DLL with some resources in it, but instead of producing a DLL, it produced a .lib and a .obj I''m using MSVC++ 6. Is there anywhere where I can learn more about DLL''s? How do I make a DLL file, and how do I use it in my exe?

You probably started a static linked library project instead of a dynamic linked library project. A .lib file is just as good in my opinion (actually better if a lot of people aren''t going to need that one library).
To use it in your .exe, you need
LoadLibrary FreeLibrary GetProcAddress.
Also, the DLL has it''s own thread, so you can also call that.
Look in MSDN (msdn.microsoft.com). I think if you look up DllExport, you''ll be on the right track. It depends whether you want to load at link time or run time as to how you link and write your project.
I wish I had time to give an example, but I don''t right now unfortunately. Good luck!
hmmm... Did you use the option that it should add some example code? If so, add a .def file to the .cpp files and get rid of those dllimport/dllexport defines and the classes... (you won''t be able to use classes then, though...)
In the .def file (a normal .txt file) you define the functions and variables the .dll exports.. (you can find it in the MSDN how to write it exactly..)
to load them in your .exe use LoadLibrary(), FreeLibrary() and GetProcAddress() as mentioned above..
one hint: delete memory where you allocated it.. in other words: If you call allocate memory in a dll function and return a pointer to the .exe be sure to free the memory in a function in the .dll...
In my current project I retrieve function pointers through functions called through function pointers... that''s where it get interesting :o)))))) cya, Phil
