Good morning,

I want to use RegEx.Replace to replace special characters in a string. I want to make sure I only have alphabetic characters in my string. All I want to do is to remove the non-alphabetic characters. Some code:

    Dim myString as String = "Me & my *buddy* love$ fishing!!!"
myString = RegEx.Replace(myString, "\[!@#$%^&*()+]", "")

For some reason this does not work so I must be doing something wrong. Please help!

You must have meant `[!@#$%^&*()+]`. The ``\`` before the first `[` made it a literal `[`. – Wiktor Stribiżew Jun 24 '20 at 08:14
Thank you. Going to test now. That was most probably my mistake. – Manie Verster Jun 24 '20 at 08:37
BTW, any non-letter can be matched with `\P{L}`. You might want to try `RegEx.Replace(myString, "\P{L}+", "")` – Wiktor Stribiżew Jun 24 '20 at 08:38
Now I only see the special characters. All the other characters removed. – Manie Verster Jun 24 '20 at 09:09
You probably used `\p{L}`.You need `\P{L}` – Wiktor Stribiżew Jun 24 '20 at 09:10
Yesss!! Thank you very much for your help Wiktor! – Manie Verster Jun 24 '20 at 09:21
