ShadowElf,

What have you tried so far? :D

What is the precise format you want? Is it a series of any number of letters, followed by either nothing or the digits "093"?

Thanubis,

Nice.

I have to keep reminding myself that just because you can do something with a RegEx, it does not always make sense to actually do so.

If you are not a guru in the blasted things, it is ofter easier (and faster!) to use other functions. :D

asdzc -> OK

asdjasd02389 -> ok

231321asd -> NOT OK

90423j)(* -> NOT OK

asd90asd90 -> OK

asd*& -> NOT ok

max 20 chars

From "ONLY LETTERS or FIRST letter and after numbers" one may translate it into:

"one or more [english] letter (casing?) followed by zero or more [decimal] digits" in the limit of 20 characters.

The 20c limit is easy:

If StringLength($str) > 20 Then ... $str is rejected , or truncated

The condition above would translate in turn into the regexp:

[a-z]+\d*

If casing should be ignored, make it (?i)[a-z]+\d* or [a-zA-Z]+\d*

Only catch: this doesn't cope with one of your examples:

asd90asd90 -> OK

So either your actual rules are in fact more complex than you said, or this example is invalid. Only you can read your mind :D

$s = "oidfgdgu73456548"

$r = StringRegExp($s, "\D+\d*", 1)

If IsArray($r) and $r[0] = $s Then
    ConsoleWrite($s & "< Allowed" & @CRLF)
Else

    ConsoleWrite($s & "< Not Allowed" & @CRLF)
EndIf

EDIT: Added check for return being an array

$r = StringRegExp($s, "\D+\d*", 1)

Hi Martin,

Sorry but this doesn't work as \D allows non-letters & non-digits ahead: $str = "$got you!159" would incorrectly match.

[:alpha:] or [a-z] wouldn't tolerate that.

One of the many ways you could do this using StringRegExp() if you wanted 

Global $aTest[6]
$aTest[0] = "asdzc"; -> OK
$aTest[1] = "asdjasd02389"; -> ok
$aTest[2] = "231321asd"; -> NOT OK
$aTest[3] = "90423j)(*"; -> NOT OK
$aTest[4] = "asd90asd90"; -> OK
$aTest[5] = "asd*&"; -> NOT ok

For $i = 0 To  5
    If StringRegExp($aTest[$i],"^[[:alpha:]][[:alnum:]]{0,19}{:content:}quot;) Then
        MsgBox(0,"Test Result" , $aTest[$i] & " is valid")
    Else
        MsgBox(0,"Test Result" , $aTest[$i] & " is not valid")
    EndIf
Next

Explanation of the regex pattern

"^[[:alpha:]][[:alnum:]]{0,19}{:content:}quot;

«^»                             Assert position at the beginning of a line (at beginning of the string or after a line break character) 

«[[:alpha:]]»               Match a single character in the range A to Z or a to z 

«[[:alnum:]]{0,19}»   Match a single character present in the range A to Z or a to z or 0 to 9 as many times as posible, between zero and 19 times 

«$»                             Assert position at the end of a line (at the end of the string or before a line break character) i.e. make sure all characters are include in the match

And another attempt.

Local $sMessage, $sResults
Local $aTestString[8][2] = [["asdzcasddzc", "OK"],["asdjasd02389", "OK"],["asd90asd90", "OK"], _
        ["231321asd", "NOT OK"],["90423jr)(*", "NOT OK"],["asdasdasd*&", "NOT OK"], _
        ["asd90asd90asd", "NOT OK"],["asdzcasddzc12345678910", "NOT OK"]]

For $i = 0 To UBound($aTestString) - 1

    $sMessage = "NOT OK"

    If (StringRegExp($aTestString[$i][0], "^[a-z]") And StringRegExp($aTestString[$i][0], "\d$")) And _ ; If start with letter & end with digit - ok
            StringLen($aTestString[$i][0]) <= 20 Or _       ; If less than or equal to 20 characters - ok
            (StringRegExp($aTestString[$i][0], "[^a-z]") = 0) Then $sMessage = "OK" ; If only letters - ok

    $sResults &= $aTestString[$i][0] & @TAB & $aTestString[$i][1] & " expected. Result is " & $sMessage & @CRLF

Next

MsgBox(0, "Results", $sResults)
