[quote user="Jon Summers"]Full match 40-48 `11/16123` Group 1. 40-48 `11/16123`[/quote]
In attempting to correct this regex result, I used the online tester and arrived at this solution:
([0-9]{1,2}+\/[0-9]{1,2}+)
However, it seems that the addition of the two {1,2} qualifiers renders TextBlock::FindText() unable to find ANY fractions...
BUT, I think L"[0-9]{1,2}/[0-9]{1,2}" does the trick !!
