QUESTION
In a multiline string, in each line, I want to delete everything from the first unescaped percent sign to the end of the line; with one exception. If the unescaped percent sign occurs in the following position: \d\d:\d\d%:\d\d
, then I want to leave it alone.
(The string is LaTeX / TeX code and the percent sign denotes a comment. I want to treat a comment inside an HH:MM:SS string as a special case, where seconds were commented out of a time string.)
The code below manages almost to do it:
- it uses one negative lookbehind to leave
\%
alone - it uses "ungreedy" to match the first, not last,
%
- it uses another negative lookbehind to skip
\d\d:\d\d%
- BUT it fails to differentiate between
\d\d:\d\d%anything
and\d\d:\d\d%\d\d
, skipping both. - My attempts at adding negative lookahead do not help. Is there a way to do this?

Your queries don't contains the fields that you have named as ValueMember for your combos.
So it is not possible for it to give a precise value in the property SelectedValue but just the name of the class that is used to build a row inside the combo (a DataRowView)
If you want to get the SelectedValue set to the MuscleID or FitnessID value of the current selected item you need extract these values from the database.
