How to Use Regular Expressions in Visual Studio Find

I have to admit that I've never really understood regular expressions. But if there was any reason that I was going to learn to use them, it would be when doing searches in Visual Studio.

For one thing, regular expressions are easy to invoke when doing a search: When you press Ctrl_F to get the Find dialog box, all you have to do is click the asterisk (*) to the left of the of scope dropdown list to start using regular expressions in your search.

I think, for example, I'm ready to start using the period (which matches a single character) in my searches. That would let me (for example) search for any string that begins with a and ends with p that has only one character in between (a.p). I not only understand this, but it's also easy to extend: Looking for a and p with two characters in between is a..p.

Where I could see being even more successful is by using Replace in Files more. When you open Replace in Files there's a Use Regular Expressions option tucked in under Find Options. Checking off that option enables the button at the end of the "Find what" text box. I like that button because clicking on it produces a quick study guide for regular expression newbies like me. I could do this.

I mean: it's certainly possible that I could learn something new. Unlikely, but possible.

    How to Compute Disorder for Machine Learning Decision Trees Using C#

    Using a decision tree classifier from a machine learning library is often awkward because it usually must be customized and library decision trees have many complex supporting functions, says resident data scientist Dr. James McCaffrey, so when he needs a decision tree classifier, he always creates one from scratch. Here's how.
