  3. //  File Name 
  4. //      SERVICE.CPP
  5. //
  6. //  Description
  7. //      This is the file where the entry point is (WinMain).
  8. //      Here we also implement the registration and unregistration of
  9. //      the RPC server.
  10. //      The server register its services with NAMED PIPES as the exposed
  11. //      protocol sequence for RPC calls. This server can only be run on
  12. //      Windows NT platforms. Windows 95 does not support the creation of
  13. //      named pipes.
  14. //      This is where we register the NT service with the Service control
  15. //      manager and where the service control handler is implemented
  16. //
  17. //      The WinMain, function can take certain paramenters from the command
  18. //      line to control the action of the executable
  19. //
  20. //      Argument        Action
  21. //      ========        ======
  22. //      <None>          If normally started by the Service control manager,
  23. //                      the WINDS NT Service starts and it is ready to accept
  24. //                      request from WINDS MAPI service providers and from
  25. //                      the WINDS administrator.
  26. //                      If started as an application, a message dialog will
  27. //                      come up to allow interactive install and removal of
  28. //                      the service.
  29. //
  30. //      APP             Start the service as an APPLICATION EXECUTABLE, as
  31. //                      opposed to an NT SERVICE. This is useful for
  32. //                      debugging the WINDS server.
  33. //
  34. //      INSTALL         Adds the WINDS NT Service to the Service Control
  35. //                      Manager list, modify the registry entries and starts
  36. //                      the NT services normally.
  37. //
  38. //      REMOVE          Remove the WINDS NT service from the Service
  39. //                      control list, and stops the WINDS service, halting
  40. //                      services WINDS MAPI providers and WINDS administrators
