Expertise

I have extensive experience with VBA programming in Excel 5 through Excel 2007. I am an consultant in a small defense technology services company, and have developed a wide range of applications in VBA, including simulations involving mixed-language programming, satellite orbit mechanics, graphics and animation, and real-time applications. I am interested in moderate to hard VBA-related questions only.

Experience in the area

I have developed and taught several courses in Excel VBA programming and also VBA programming in Office 97, 2000, and 2007. I have developed a number of large technical applications in Excel VBA for use within the aerospace industry.

What do you like about this subject?

I enjoy helping others, not just to solve their particular problem, but also to improve their proficiency and understanding of Excel and VBA. As a result, I always try to explain why a particular problem has occurred and why a particular solution works rather than just providing a solution.

Something interesting about this subject that others may not know:

VBA is a powerful general-purpose scripting language, not just a macro recording capability. When one learns to program in VBA rather than just recording macros, a whole world of new capabilities opens up.

Something controversial or provocative about this subject

Contrary to the belief of many, VBA is exactly the same in Microsoft Excel, PowerPoint, Word, and Access. It is only the object models of the hosting applications, and therefore the way one works with their objects, that are different. As a result, once one knows VBA one need only learn the object model of any new application to program effectively in it.
