Windows NT - Exception Handling Example
=======================================

As a developer, I think that Structured Exception Handling is
one of the most attractive features of NT.  I want to share 
what I've stumbled through in my first effort.  There isn't 
much here, but I haven't seen a good example anywhere else.
  
The approach here is to generate a Message Compiler source 
(.MC) file.  From this, the Message Compiler (MC.EXE) creates 
a binary (string) resource, a Resource Compiler Source (.RC) 
file and a C Language Header (.H) file.  
The string resource is built into a resource-only DLL using the
.RC file.  The .H file is used by programs to generate
exception codes. (See WINERROR.H for the system exceptions) 

This package contains the ingredients of a demo-version DLL, 
(B4DMSG.DLL) and for a small program (MAIN.EXE) to force an 
exception when a key is pressed.

The DLL
=======

B4DMSG   MAK         661 03-02-93  06:09PM 
Builds the dll, this comes from the readme file in the
RESDLL example on the October SDK CD.
	
THE_DLL  C          1309 02-28-93  04:30PM 
Boilerplate DLL wrapper, this comes from the readme file in 
the RESDLL example on the October SDK CD.

B4DMSG   DEF          18 02-28-93  04:43PM 
Module Definition file for the DLL, from RESDLL.

B4DMSG   MC          503 03-02-93  06:15PM 
Message compiler source file.  The best documentation
for this is MC.HLP.

B4DMSG   H          1347 03-03-93  05:49PM 
Header file generated by MC.EXE from B4DMSG.MC.  I threw this in
so you don't have to run the make to see it.  See also WINERROR.H.

A Class to hide the DLL
========================
B4DMSGRS H          1482 03-02-93  06:56PM 
Class definition for B4DMsgResource, a class that hides the
Exception DLL.

B4DMSGRS CPP        1511 03-02-93  05:59PM 
Class implementation for B4DMsgResource, a class that hides the
Exception DLL.

The demo program
=================

MAIN     DEF         267 03-18-92  08:32AM 
Module Definition file for the Demo Program.
Copied from RESDLL

MAIN     H           709 02-28-93  05:26PM 
Header file for the Demo Program.
Copied from RESDLL

MAIN     MAK         395 03-02-93  06:12PM 
Make file for the Demo Program.
Copied from RESDLL

MAIN     CPP        4581 03-02-93  05:57PM 
Source file for the Demo Program.
Copied from RESDLL

MAKEFILE             125 03-03-93  05:47PM 
This builds the whole pizza.  Note that the DLL 
must be built before the EXE.
