  • Blog Post: Did you know? You can unwind the call stack from exceptions (Bill Horst)

    The ability to unwind the call stack from exceptions is one of the debugger features that was newly introduced in Visual Basic.NET 2005. When the debugger hits a first-chance exception, you can unwind the call stack in order to make code edits to fix the exception and continue debugging with the changes...

  • Blog Post: Converting SQL to LINQ, Part 10: Like (Bill Horst)

    This post assumes you’ve read my previous Converting SQL to LINQ posts. I haven’t had much in the way of specific requests for more LINQ posts, so I’d still welcome any suggestions that people want to offer. I did get one request about how to mimic the LIKE keyword functionality in VB LINQ. ...
  • Blog Post: STAThread vs. MTAThread (WHorst)

    I recently ran into an interesting threading problem that I wanted to share, so that perhaps I can save some people from the same confusion I had. I started with a C# application someone else had written. I’ll call it “DeltaEngine” for the purpose of this post. DeltaEngine calls into a native assembly...

Once again, I recognize this isn’t an ideal situation, so if you’d like to see better support of Full Outer Join in a future VB release...
  • Blog Post: Converting SQL to LINQ, Part 8: Left/Right Outer Join (Bill Horst)

    This post assumes you’ve read the previous posts in this series. After my post on joins , I’ve had some questions about outer joins. As you can see in part 6, VB9 doesn’t have smooth support for Left or Right join. I showed how to get similar functionality with Group Join, but I’ve looked into...

  • Blog Post: Converting SQL to LINQ, Part 1: The Basics (Bill Horst)

    As you may already know, VB LINQ statements enable SQL-like syntax for queries in the VB language. LINQ syntax doesn't match SQL syntax exactly, so if you are already working with SQL or familiar with SQL queries, you may find yourself wanting to convert an existing SQL query to LINQ. This will be...
