// You will need the NT SUR Beta 2 SDK or VC 4.2 in order to build this 
// project.  This is because you will need MIDL 3.00.15 or higher and new
// headers and libs.  If you have VC 4.2 installed, then everything should
// already be configured correctly.

// Note: Proxy/Stub Information
//		To build a separate proxy/stub DLL, 
//		run nmake -f ComDemops.mak in the project directory.
