In Visual Studio 2010, how do you search for text that is not within a single line comment? E. G. how to find "bas" in:
foo bar bas
but not in
foo bar // bas
Note that it should find the line:
foo / bar / bas
(edit) And it should not find the line:
foo // bar bas

Okay, so I asked this question just so I could refer back to my own answer.
Visual Studio doesn't seem to have the typical look-ahead, look-behind constructs. It does have a similar zero-width negative assertion. The syntax is ~(x) which means the pattern does not match x at this point in the pattern. Using this construct, I came up with this: ^(.~(//))*bas Which works really well, but won't exclude a line where // are the first two characters on the line. A version to fix that is: ^~(//)(.~(//))*bas

In the Visual Studio Find dialog, try using this regular expression (make sure to select Use: Regular expressions in the Find options):
~(//[.:b]*)<bas>
This should find all occurrences of the word bas which are not preceded by //.
Note that the Visual Studio regex syntax is a bit different than the conventional syntax. You can find the reference HERE.
