B4J Question File.ListFilesFilter ??

[Firpas]

How to apply a mask filter (like "My*.tx?", or "*.txt", or any other one) to a File.Listfiles ??

Perhaps applying Regex.IsMatch, but ... how? taking into account the many possible combinations of "*" and "?"

Thanks in advance

You have to learn the RE syntax.
Online regex tool for testing: http://basic4ppc.com:51042/regex/index.html

Something like:

Dim filteredList As List
filteredList.Initialize
For Each s As String In File.ListFiles(...)
 If Regex.IsMatch ("My.*\.tx.", s) Then filteredList.Add(s) '*.txt => .*\.txt
Next

Thanks for your quick answer.
I think I have not explained well in my previous post.
What I want is to convert to a regex wildcard expression

I think it's solved.

I've attached a example project.

Thanks for your colaboration.
