This diskette contains a sample version of the SQL Sniffer application from
Blue Lagoon Software.  This application is designed to assist developers in
developing Windows based front-ends to Microsoft or Sybase SQL Server.

All applications which act as SQL Server front-ends communicate with SQL
Server through a dynamic link library called W3DBLIB.DLL.  Although develop-
ment environments such as Visual Basic and Power Builder allow the programmer
to code to a higher level SQL API, these APIs in turn call functions in
W3DBLIB.DLL.  The purpose of this utility is to SNIFF the most commonly
used dbLib functions and provide feedback to you the programmer so you can
quickly find your programming errors.

Lets assume that you have created a LOGIN dialog box which contains entry-
fields for the server, username, and password which is not functioning
properly.  When the user presses the OK pushbutton, the LOGIN API for your
programming environment is called and it returns a failed error code.  Rather
than loading up your code, you can simply run the SQL Sniffer and it will
show you exactly what was sent to SQL Server and what the return VALUE from
SQL Server was!  You may find out that you have been converting the password
to uppercase all along when SQL Server expects an upper and lower case mix.

This is a very crude example of what you can do with the SQL Sniffer, this is
why we have made a sample version available which hooks a small handful of
_dbLib functions.  We hope this will give you an idea of what you can
accomplish with the RETAIL version and you will give us a call and order
a copy today.  We have even included the product's help file to explain
how to use the SAMPLE.

Included in this ZIP archive are the files needed to install and execute
the sample version of SQL Sniffer, this readme file, and a Word for Windows V2.0
version of the SQL Sniffer product information document.

We hope you enjoy the SAMPLE program.

Sincerely,
