VCEnum.exe is comprised of the following files:

   File             Description
   ----------------------------------------------------------------------

   CON_Enum.c       Application front end that dynamically loads the VCENUM
                    VxD sample, calls it, and displays data returned from
                    the VCENUM VxD.

   VCENum.c         Sample VxD written in C. This VxD supports the WIN32
                    DeviceIOControl interface, which is used by WIN32 to
                    communicate with VxDs. This VxD can be loaded both
                    dynamically and statically.

   VCECtrl.asm      Part of sample VxD that contains the SystemControl
                    message dispatcher.

   VCENum.h         Header file used by VCENUM.C. There are VXDINLINE
                    wrappers defined in this header file.

   Makefile         Makefile for building the VCENUM VxD sample.

   VCENum.def       Module Definition file that is used by the Microsoft
                    Visual C++ 2.2 Linker. The MSVC22 linker displays
                    warnings during linking, these are expected and can be
                    ignored for this sample.
