// Wsb.cpp : Implementation of DLL Exports.

// 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 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.  
//
//      Modify the custom build rule for Wsb.idl by adding the following 
//      files to the Outputs.  You can select all of the .IDL files by 
//      expanding each project and holding Ctrl while clicking on each of them.
//          Wsb_p.c
//          dlldata.c
//      To build a separate proxy/stub DLL, 
//      run nmake -f Wsbps.mak in the project directory.
