Now available, Dan Appleman's latest Ebook: Dan Appleman's Exploring VB6 Volume 1: Essentials
This best-of collection covers a variety of topics, mostly at an intermediate to advanced level. Originally published in Pinnacle's Visual Basic newsletter or Fawcette's Visual Basic Programmer's Journal (now Visual Studio Magazine) for the VB6 audience, the articles have been updated and in some cases expanded for this collection. Where appropriate, a VB .NET supplement has been added to show how the problem would be addressed in VB .NET and/or C#.
- A DLL is a DLL is a DLL - Learn about the different types of DLLs.
- The Ten Commandments for Safe API Programming - Essential information for anyone making API calls from VB6.
- When a bug is not a bug - How mistakes in debugging can lead you to detect bugs that don't really exist.
- Taking the Long View - How to correctly handle versioning for your ActiveX components.
- CheapTrace - Shows how to implement a "cheap" tracing application using SendMessage and a list box.
- The Query that came in from the Cold - If this story doesn't teach you the importance of the ByVal keyword, nothing will.
Dan Appleman's Exploring VB6 Volume 1: Essentials available now for $7.95.
Tech Tip: ASP.Net Hosting and Code Access Security
With an increasing number of hosting services offering ASP.NET hosting, you can take advantage of the fact that most do not require expensive component verification for ASP.Net components thanks to the presence of code access security. But if your components are not tested against your hosting services security policies, you can find testing and deployment to be a challenge. Learn how CAS/Tester can simplify this process by making sure your component will work on a hosted site.

Tech Tip: Register your COM Components Programatically
Updating COM components in situations (such as auto updates) is not just a matter of copying files. You often need to register them as well. Shelling to RegSvr32 can work, but has limitations. Learn how you can directly register components from any VB6 application without RegSvr32 in this new article.
