// Note: Proxy/Stub Information
//        To merge the proxy/stub code into the object DLL, add the file 
//        dlldatax.c to the project.  Make sure precompiled headers 
//        are turned off for this file, and add _MERGE_PROXYSTUB to the 
//        defines for the project.  
//
//        If you are not running WinNT4.0 or Win95 with DCOM, then you
//        need to remove the following define from dlldatax.c
//        #define _WIN32_WINNT 0x0400
//
//        Further, if you are running MIDL without /Oicf switch, you also 
//        need to remove the following define from dlldatax.c.
//        #define USE_STUBLESS_PROXY
//
//        Modify the custom build rule for sdpblb.idl by adding the following 
//        files to the Outputs.
//            sdpblb_p.c
//            dlldata.c
//        To build a separate proxy/stub DLL, 
//        run nmake -f sdpblbps.mk in the project directory.
