How do I check if a string contains only "normal" chars

[Info]

By "normal" chars I mean only these chars:

a-z

0-9

.

_

I thought of something like

Func _AcceptedChars($data)
    If CharsOkay Then
        Return True
    Else
        Return False
    EndIf
EndFunc

thanks

Func _AcceptedChars($data)
    If StringRegExp($Data, "(?i)^[0-9a-z]+$") Then Return True
    Return False
EndFunc

EDIT: Changed an incorrect character in the RegExp

thanks!

You are most welcome. The same thing can be accomplished by changing the SRE to

StringRegExp($Data, "^[[:alnum:]]+$")

You can learn the power of SRE's with the toolkit in my signature.

And heres me navigating around regex, as usual.

$rtn = _Chars("abcdefghijklmnopqrstuvwxyz0123456789")
ConsoleWrite($rtn & @LF)

Func _Chars($sString)
    Local $b = True
    $atemp = StringSplit($sString,"",2)
    For $i = 0 To UBound($atemp) - 1
        If Not $b Then Return False
        $stemp = Asc($atemp[$i])
        If Not (($stemp > 47 And $stemp < 58) Or ($stemp > 96 And $stemp < 123)) Then
            $b = False
        EndIf
    Next
    Return True
EndFunc

Like most people, I don't particularily like REgExps either, but I do recognize their power and that alone makes it worth learning how to use them. It's all personal preference, for example you love consolewrite. If you ever sent code to me that used it there is a good chance it would never even get more than a cursory glance unless it was important enough to change all of the consolewrites to Msg Boxes or some other form of checking the results.
