See any of these google articles. Many of them are for VB, but you can just ignore that part and read about how to write the dll.
One important point: memory cannot be allocated in a dll and deallocate it in the calling application. Special non-ansi-standard functions such as GlobalAlloc() and GlobalFree() can be used, not neither new or malloc().
