Question

I am trying to check if a users input contains any special characters from a list, does anyone know who I would go about doing this?

I’ve tried the LIKE operator:

 Dim sMatch As Boolean = tTitle.Text Like "[-/\,.:;*?""""<>|&'[]^%£$()_+=!#]"

but doesn’t seem to work, i think special characters are used for settings.

Is there a RegEx i could use for this??

Thanks for any help.

Answer 1

IndexOfAny and ToCharArray will help here

Dim sMatch As Boolean = tTitle.Text.IndexOfAny("-/\,.:;*?""""<>|&'[]^%£$()_+=!#".ToCharArray) > -1

edit: Some of those characters have to be wrapped in their own square brackets for the like to work, plus you’d need some *’s around the [], and you’d have trouble square bracketing the ] itself – Like Operator (Visual Basic) 🙂
