Question

I need a regular expression that will match this pattern (case doesn’t matter):

066B-E77B-CE41-4279

4 groups of letters or numbers 4 characters long per group, hyphens in between each group.

Any help would be greatly appreciated.

Answer 1

With such a small sample of data, it’s not easy to be certain what you actually want.

I’m going to assume that all the characters in that string are hex digits, and that’s what you need to search for.

In that case, you would need a regular expression something like this:

^[a-f0-9]-[a-f0-9]-[a-f0-9]-[a-f0-9]$

If they can be any letter, then replace the fs with zs.

Oh, and use myRE.IgnoreCase = True to make it case insensitive.

If you need further advice on regular expressions, I’d recommend http://www.regular-expressions.info/ as good site. They even have a VB.net-specific page.
