CreateRegex(regexSpec As String, Optional ignoreCase? As Boolean = true, Optional singleLine? As Boolean = true) As Any
RegexMatch?(testString As String, regex As Any) As Boolean
regex can be:
- string - in that case regex ignores casing, and single line.
- object created by CreateRegex()

Usage

In design:

Rule r As Any = createRegex("^[a-zA-Z0-9]\d{2}[a-zA-Z0-9](-\d{3}){2}[A-Za-z0-9]$")

In Immediate window:

Intent >RegexMatch?("0919-2893-1256", r)
--> False
Intent >RegexMatch?("A08Z-931-468A", r)
--> True

Or simplified:

Intent >RegexMatch?("_A90-123-129X", "^[a-zA-Z0-9]\d{2}[a-zA-Z0-9](-\d{3}){2}[A-Za-z0-9]$")
--> False

For case sensitive regex matching:

Rule r As Any = createRegex("^a", ignoreCase? := False)
 
Intent >RegexMatch?("A", r)
--> False
