DESCRIPTION: Functional VB developer's tool to prevent decompilation
(reverse engineering) of Visual Basic .EXE into exact source code. Retain your
trade secrets. Lock up your code. The latest version is available from the publisher or
as SWREG to randomize your executable code, remove object references, and 
make decompilation more unlikely. Must run INSTALL.EXE. SWREG #8135

OVERDEMO.EXE is a demonstration application which counters the threat from
several tools which input Visual Basic .EXE files and convert them into 
fully functional, clearly readable, debuggable VB source code. It really works on
most VB applications. Must run INSTALL.EXE.

OVERRIDE.EXE is the latest version with online help, randomized marking of
executable code, no "unregistered" screens, and added options to remove reference
to VB source code objects and modules. It costs $21 US. Shipping is through 
CompuServe (free), or by disk through various standard land services (extra).

This tool is designed to counter the reverse engineering threat from DoDi's 
Discompiler. It makes it more difficult (but never impossible to extract
window resources from a compiled Visual Basic application. This devloper's
tool uses some information from Daniel Berlin 72440,1573, but the algorithms
are designed solely by Marty Nemzow (70373,1350). There is no guarantee to
this software, the effectiveness of this software, demo or otherwise, and 
the user is alone is responsible for its application. This software in its
current form does check the .EXE file to see if it is indeed a VB program, 
so consider not running it against non-VB applications.

This tool is a compiled VB application. It requires VBRUN300.DLL and other
basic VB development resources. If you are not a VB developer and do have some
version of VB.EXE (for example, 1.0, 2.0, 3.0, or 4.0, standard, professional or 
enterprise) this tool is without utility to you. If you encounter problems, please send
E-mail to (70373,1350 or via internet at npi@shadow.net).  You can get additional
information about current books and software from NPI from a WWW page at 
uniform resource locator http://anshar.shadow.net/~npi/npipage.html. 

By the way, Marty has a VB book coming out aimed at corporate developers, 
shrinkwrap developers, shareware developers, and others working seriously
with Visual Basic. This is not an introductory book, it is less about code 
and more about the development process. See the file VBBOOK.TXT for more 
info about the "VB Developer's Toolkit."
