// init.cpp : Implementation of DLL Exports.


// 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 AUO.idl by adding the following 
//		files to the Outputs.
//			AUO_p.c
//			dlldata.c
//		To build a separate proxy/stub DLL, 
//		run nmake -f AUOps.mk in the project directory.
