In yesterday’s post we saw that the use of the wrong comparison operator with Nothing in an If block can lead to surprising results.  Let’s look at a slightly different case today:         Dim x As Integer = Nothing         If x = Nothing Then &nbs...

Microsoft has this neat mailing list called “Spot the Bug” where developers can send interesting snippets of code that look correct but actually have subtle bugs in them.  The puzzles are a lot of fun and I’ve always thought it’d be a fun thing to try here on the team blog.  Over the past year or so I’ve been keeping a list of interesting...

We’ve started two new “How Do I” videos series on the Visual Basic Developer Center. More to come, but here’s the latest!
