Visual Studio - hexadecimal editor

I have a project that parses large text files from one third-party source into a bunch of small text files for another third-party printer interface.
Using Regular Expression and Hexadecimal File Editors have been a base necessity.
For example, almost none of the newer print systems use a Form Feed - character code 12 in decimal (0xC in hexadecimal) - Chr(12) -Regular Expression \f - Hexadecimal View 0C
Of course, the third-party printer interface in this scenario required the Form Feed be kept in position.

Nearly every six months, like this week, another alteration is asked for and I find myself back in the code.



Due to the infrequency of use, I find it difficult to keep the details of Regular Expression syntax in my head so I use Expresso from Ultrapico (http://www.ultrapico.com/) which does an excellent job of translating what I want into a .NET Framework Language code snippet.

For my project development I use Visual Studio 2008 SP1 which has as much of a hexadecimal editor "Binary Editor" as I need.
