What is the difference between classes and modules?

Q: What is the difference between classes and modules?

A: Visual Studio.Net stores code in either classes or modules. Classes are used for items that define their own storage and have persistent data. In addition classes must be instantiated before they're used, unless the keywords "Static" (C#) or "Shared" (VB.Net) are used.
Modules, on the other hand, can be viewed as simple code libraries where the methods can be called directly.

Working with double quotes (") in VB.Net

String manipulation in VB2005 is fairly simple. However, things can get a little tricky with the double quote character. How do you look for it in a string? How can you insert into a string?

FoxCon 2019

This year I had the privilege of being invited to FoxCon for the 5th time.  FoxCon is a private invite-only conference.  It was started decades ago when FoxPro was one of the products from Microsoft.  Although the product is no longer supported, it is still widely used and loved at many organizations of various sizes.  The FoxCon conference targets FoxPro related topics but the organizers are always open to hear new topics. This year I presented 2 sessions: "SQL Server Security"  and "New Features in SSRS 2017".  Presenting to a technical audience is something I have always enjoyed.  However, it seems much more enjoyable presenting to this group of tech experts. I look forward to attending and possibly presenting again next year.
