Welcome to the second article in the .NET secrets series!

I'm Karl Moore and, once again, you're reading another bundle of secrets I've adapted from my soon-to-be-released book, VB .NET and ASP.NET Secrets.

This week, I'm continuing to look at Windows application secrets. Today, we'll figure:

  • The .NET method of checking for a previous instance
  • How to convert the contents of a RichTextBox control to HTML
  • What you need to do to support dragging-and-dropping from Windows Explorer
  • The exact code you need to capture the screen, quickly and easily

Got any .NET tips and tricks of your own? I'd love to hear about them and possibly formulate them into this series (with full credit given, naturally!). Drop me a line—karl@karlmoore.com.

But without further ado... the secrets!
