Question

Works:

static void WINAPI ServiceStart(DWORD argc, LPTSTR* argv);

int main() {
   SERVICE_TABLE_ENTRY DispatchTable[] = {
      {"MyService", ServiceStart},
      {NULL, NULL}
   };
}

Doesn’t work:

error C2440: ‘initializing’ : cannot convert from ‘void (__stdcall Service::* )(DWORD,LPTSTR *)’ to ‘LPSERVICE_MAIN_FUNCTIONA’

class Service {
   static void WINAPI ServiceStart(DWORD argc, LPTSTR* argv);
};

int main() {
   SERVICE_TABLE_ENTRY DispatchTable[] = {
      {"MyService", Service::ServiceStart},
      {NULL, NULL}
   };
}

You must use & in that context to obtain a correct pointer.
