GLASS.CPP

// Glass.cpp : Implementation of DLL Exports. 
 
// You will need VC 4.2 and the full 4.2b patch (http://msvc/vc42b/vc42b.htm) in  
// order to build this project.  This patch includes the final NT 4.0 SDK. 
// You will also need MIDL 3.00.75, which is included with ATL 2.0. 
 
// Note: Proxy/Stub Information 
//To build a separate proxy/stub DLL,  
//run nmake -f Glassps.mk in the project directory.
