Property (As String )
aRegEx.ReplacementPattern = newStringValue
StringValue = aRegEx.ReplacementPattern

Supported for all project types and targets.

This is the replacement string, which can include references to substrings matched previously, via the standard '\1' or '$1' notation common in regular expressions.


This pattern is used either with the Replace property or passed to the RegExMatch class when Search returns, and subsequently used with Replace if no parameters are specified.
