  1. // cmdstub.cpp : Implementation of DLL Exports.
  2.

  4. // Note: Proxy/Stub Information
  5. //      To merge the proxy/stub code into the object DLL, add the file 
  6. //      dlldatax.c to the project.  Make sure precompiled headers 
  7. //      are turned off for this file, and add _MERGE_PROXYSTUB to the 
  8. //      defines for the project.  
  9. //
  10. //      If you are not running WinNT4.0 or Win95 with DCOM, then you
  11. //      need to remove the following define from dlldatax.c
  12. //      #define _WIN32_WINNT 0x0400
  13. //
  14. //      Further, if you are running MIDL without /Oicf switch, you also 
  15. //      need to remove the following define from dlldatax.c.
  16. //      #define USE_STUBLESS_PROXY
  17. //
  18. //      Modify the custom build rule for cmdstub.idl by adding the following 
  19. //      files to the Outputs.
  20. //          cmdstub_p.c
  21. //          dlldata.c
  22. //      To build a separate proxy/stub DLL, 
  23. //      run nmake -f cmdstubps.mk in the project directory.
