INTRODUCTION
------------

The disk provided with this application note contains Simple MAPI
files for both Microsoft C and Microsoft Visual Basic(TM). These are
replacements for the Simple MAPI files included with Microsoft Mail
for PC Networks, version 3.0. The replacement files resolve two
problems that can occur when creating Simple MAPI applications. MAPI.H
has been modified to be strictly ANSI compatible, and will no longer
cause warnings on Warning Level 4 with the Microsoft C version 7.0
compiler. The sample Visual Basic Simple MAPI application has been
modified to compile when using Microsoft Visual Basic version 2.0.

TO REPLACE YOUR SIMPLE MAPI FILES
---------------------------------

1. Insert the enclosed WA0729 disk into your floppy disk drive.

2. At the MS-DOS command prompt, type the following and press ENTER

      xcopy <drive:>\ <destinationdirectory> /s

   where <drive:> is the floppy disk drive containing the WA0729 disk
   and <destinationdirectory> is the drive and directory where your
   Simple MAPI files currently reside. For example, if your Simple
   MAPI files are located in the MAILEXE\TECHREF directory on drive C
   and the WA0729 disk is in drive A, type the following command:

      xcopy a:\ c:\mailexe\techref /s

   A message will be displayed stating: "10 file(s) copied." This
   indicates that your Simple MAPI files have been successfully
   replaced.
