Question about Regex

Code:

---

mTrack = new Regex(@"^%B\d{8,19}\^.{1,26}\^\d{2}(01|02|03|04|05|06|07|08|09|10|11|12)\d{3}((.{9,57})+|\^)\?", RegexOptions.None);

---

between the two ^ it says minimum 1 , Maximum 26
This I imagine could any alpha numeric value.

How can I ensure that this 1,26 byes do not appear in lowercase.
Meaning aBCD-3/5 RFG is not allowed
but ABCD-3/5 RFG is
mind you only inserting [A-Z] does not allow for - & / to be valid , and that is not what I want
Cheers

Google Regular Expression Set's (A set can be defined inside of an open and closed bracket)

I have attached a small application that I wrote when I was learning regular expressions, the zip file also contains a set example that you can check out.

JPederson, it would be more helpful if you supply any form of code, and not just attach the exe.

Thank you for understanding
