How to find special characters and numerals in a textbox

Continuing the discussion from How to find special characters in a text:

I am using the Taifun Text Box extension, for which I added a procedure to check for abusive usernames. If a user inputs a word from an abusive word list along with a numeral, the username should not be created. However, I’ve encountered an issue with this regex extension where the app crashes when I use it.

The error message means, you created an endless loop


Yes, sirji. How can I use your text box extension and regex extension at the same time? Any suggestions?
