This web site is brought to you as a public service by Chip
Pearson and Pearson Software Consulting, LLC. We provide complete
consulting and custom application design and development for Excel, Office, Visual Basic,
and the NET Framework in VB.NET and C#. For more information about how to turn Excel into a
powerful application platform, contact Chip Pearson at (816) 214-6957. Please call between 9:00 AM and
7:00 PM, USA Central Time (-6:00 UTC).
This web site contains about 500 individual topic pages that together cover all
aspects of Excel, from simple formulas through Automation and COM Add Ins and into the NET
Framework. The content is aimed
at the intermediate level user although there is plenty of content for both beginners and expert users. Much
of the content is VB/VBA/VBNET code, and those pages assume that you are
conversationally familiar with VB/VBA programming. I have been a professional computer programmer
for almost twenty-five years, fifteen years of that in the Windows/VB/VBA/Excel world.
The topics presented on the site are drawn from my real world experience. There
are approximately 250 downloadable files, which include sample workbooks, VB/VBA modules,
VB Project source code and compiled DLL files.
The content of the site provides you with the tools you need to create
workbooks and VBA projects. Since it is impossible to be all things to all people,
the workbooks, formulas, and code examples are rather generic, allowing you to
readily customize them for your own particular needs. The formulas and code
appearing on this site should work in any version of
Excel, version 97 or later, unless noted otherwise. Most of the VBA code should
work in Excel 97 and later, but I do make use of the enhanced features of VBA
version 6, which was introduced with Excel 2000.
I have not yet upgraded all the modules to 64-bit Office, so some of the code may
not work in 64-bit Office, especially code that uses the Windows API functions
with the Declare syntax. Don't confuse 64-bit Office with 64-bit Windows. All of
the code will work fine in 32-bit Office, regardless of whether you have 64-bit
or 32-bit Windows.
Expansion Of Consulting And Programming Services
I am expanding my design and development services to include a much broader
approach to integrating Excel with the other products in the Microsoft Office
family, to SQL and XML data stores, and web services. I am also expanding into
Windows Presentation Foundation (WPF) desktop and browser-based applications.
I can now provide development and design services for a much broader range of
applications and services. I have the best-in-class tools for all types of NET
desktop and browser applications.
