Check string for specific characters!

[bafh]

Hello,

I have a string and want to check if it only contains lowercase characters from (ascII) 47-58 and numbers.

How would I do that, as short as possible because i dont want to do things like

If $var[1] = a then exit

If $var[1] = b then exit and so on

thanks for answering

You mean something like this?

$string = 'abcdefghijklmnopqrstuvwxyz0123456789'
$test = 'This is a Test'

    For $x = 1 To StringLen($string)
        If(StringInStr($test,stringmid($string,$x,1),1)) Then
            ConsoleWrite("Found: " & stringmid($string,$x,1) & @LF)
        EndIf
    Next

Hmm,

no, what i want is to check a string for its characters and only allow characters from a-z and numbers from 0-9, and if the string contains any other characters to make an error.

[GaryFrost]

might want to look at the StringIsAlNum function then

Yes,

but there could also be letters,so, if I ceck it for alphanumeric it checks for letters from ascII code 0-125 or something, but i only want 0-9 and a-z

also alows for space

$string = 'abcdefghijklmnopqrstuvwxyz0123456789 '
$test = 'This is a Test 9'
$string_ok = 1
    For $x = 1 To StringLen($test)
        If(StringInStr($string,stringmid($test,$x,1),1) == 0) Then
            $string_ok = 0
        EndIf
    Next
ConsoleWrite($string_ok & @LF)
$test = 'this is a test 9'
$string_ok = 1
    For $x = 1 To StringLen($test)
        If(StringInStr($string,stringmid($test,$x,1),1) == 0) Then
            $string_ok = 0
        EndIf
    Next
ConsoleWrite($string_ok & @LF)

Example:

$string = 'abcdefghijklmnopqrstuvwxyz0123456789 '
$test = '"234hsjdfh=)(/"·$" ?'
$string_ok = 1
    For $x = 1 To StringLen($test)
        If(StringInStr($string,stringmid($test,$x,1),1) == 0) Then
            $string_ok = 0
            ExitLoop
        EndIf
    Next
If (Not $string_ok) Then
    ConsoleWrite("String has characters not allowed" & @LF)
EndIf

output

As I see it there is only a few string manipulation functions build into Autoit and that's StringInStr, StringReplace and StringMid well one could count stringleft/right, Lower/upper and StringLen in but that's all and you has to do with that no matter...
