I have the thankless task of editing a ton of HTML files.  I have a bunch of URLs that all have different IDs, but I want to point to the same place.  So, I investigated regex searching in VS.  Well, the regex was easy, and the search found all my strings.  Replace, however, leaves the regex section behind.  My search was s=c&vl=vlg&vi=\d*, and it would replace s=c&vl=vlg&vi= and leave my digits behind.  
Some googling told me that VS has it's own Regex syntax ( although using standard syntax WAS matching my strings ), so I tried that.  Still no dice, I get matches, but it won't replace the bit matched by regex.  I am unsure what the point of that is.
So, I decided to try wildcards.  s=c&vl=vlg&vi=#* works perfectly, it searches AND replaces.  So, I showed it to friends I'd been asking for help with the regex.  Some guy says 'but you always want there to be a number, * is zero or more'.  I KNOW I was reading MSDN, so I grab the entry to prove him wrong.  Here is the text from MSDN:
One or more characters   *   Matches zero or more characters. For example, new* matches any text that includes "new", such as newfile.txt.
So, is it one or more, or zero or more ? It's one or more.  But, I had to test, because the documentation contradicts itself.  How very helpful.
