How to restrict inputboxes to specific characters only?

13 posts in this topic

I'm having trouble in making an input box where I can limit the characters that can be inputted.  Anybody have an idea how this can be done in Auto IT?

Specifically I would like to create an input field where the user would enter a MAC address.  What I would like to do is to limit the characters that can be inputted to only HEX values (A-F and 0-9 as well as the - character).  This is so that the user cannot input invalid characters. The program is going to be used by very non-technical people, so the idea is to remove as many chances for errors that we can think of.  I would also prefer to limit the field to only 17 characters, so that there is only enough space to enter the MAC address with the - character as the separator.

Thank you all in advance for any suggestions!

I have been trying to learn more about RegEx recently, so I'm no expert, but I think this will work.

Do
   Local $sValue = InputBox("Testing", "Enter the MAC Address.", "", " M17")
Until StringRegExp($sValue, '([0-9a-fA-F]{2}[-]){5}([0-9a-fA-F]{2})') = 1

Slight edit to allow for lowercase a-f

This should work to do it dynamically  :)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <EditConstants.au3>

Opt("GUIOnEventMode", 1)

$hGUI = GUICreate("Test", 232, 90)
$Label = GUICtrlCreateLabel("Enter MAC address", 22, 8, 163, 17)
$input = GUICtrlCreateInput("", 22, 30, 165, 24)
GUICtrlSetLimit(-1, 17)
GUICtrlSetFont(-1, 12)
GUISetState()

GUIRegisterMsg($WM_COMMAND, '_WM_COMMAND')
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")

While 1
  Sleep(10)
WEnd

Func _WM_COMMAND($hWnd, $Msg, $wParam, $lParam)
 Local $id = BitAND($wParam, 0x0000FFFF)
 Local $code = BitShift($wParam, 16)
   If $id = $input AND $code = $EN_UPDATE Then
       Local $content = GUICtrlRead($input)
       Local $len = StringLen($content)
       Local $char = StringRight($content, 1)
       Local $mod = Mod($len, 3)
       If not (( ($mod = 1 or $mod = 2) and StringRegExp($char, '[[:xdigit:]]') ) OR _ 
           ($mod = 0 and $char = "-")) Then GUICtrlSetData($input, StringTrimRight($content, 1)) 
    EndIf
    Return $GUI_RUNDEFMSG
EndFunc

Func _Exit()
    Exit
EndFunc

A slight optional addition for a better look  :D

Func _WM_COMMAND($hWnd, $Msg, $wParam, $lParam)

   ;....

   If not (( ($mod = 1 or $mod = 2) and StringRegExp($char, '[[:xdigit:]]') ) OR _ 
           ($mod = 0 and $char = "-")) Then 
       GUICtrlSetData($input, StringTrimRight($content, 1)) 
   Else
       GUICtrlSetData($input, StringUpper($content))
   EndIf

Mikell,

I'm not sure what I am missing, but when I paste in your additional code, it errors out. (the original one works great!)

By the way, excuse my ignorance, but where in the code does it specifically state that only a-f and 0-9 and - are allowed?  I'm trying to figure this out, because your code is very useful, and I could see myself using it for other projects as well, where I would want to limit what characters can be inputted.  Seeing as how in other projects I might want to limit the input to a different set of characters, I would like to know how to change it.

When you create an input box you can set the length of characters, digits only, Uppercase, Center like this.

GUICtrlCreateInput Style Options

$ES_NUMBER        ==  Accepts only digits [0-9]
$ES_UPPERCASE   ==  Converts all characters to uppercase
$ES_LOWERCASE  ==  Converts all characters to lowercase
$ES_CENTER          ==  Centers text

GUICtrlSetLimit ( controlID, max , OPTIONAL min )  == so you can set a max and min character length for an input control
 

 $UserInput = GUICtrlCreateInput("", 120, 292, 161, 21, BitOR($GUI_SS_DEFAULT_INPUT, $ES_CENTER,$ES_NUMBER))
  GUICtrlSetLimit($UserInput, 10) ; Limit User Input to 10 Characters, can also just use -1 instead of variable of input box if this line is directly under like here

iAmNewbe,

Thanks! that worked great!  I see that the additional code that mikell sent me was to make the MAC address always appear as uppercase, no matter how it was typed, but thanks to the style options you showed me for GUICtrlCreateInputStyle, I simply added the "$ES_UPPERCASE" style command and it now displays the MAC address always in upper case, no matter how it is typed.

There are more options but the rest are mainly display of the box itself those I put above are the most useful. You can also use RegEx as MuffinMan shows for more involved things but if all you want is to limit to digits only that is built in using that style option.  The manual is an important read, I think over the last two weeks I went through it like a 100 times.

Sorry for the lack of explanations  :>

In fact the code actually forbids the last character written if not Hex or '-' depending on the length of the string
Here it is, detailed

Local $content = GUICtrlRead($input)
; get the string length
Local $len = StringLen($content)   
; get the last character entered
Local $char = StringRight($content, 1)  
; Mod returns 1 if length=1, 2 if length=2, 0 if length=3, 1 if length=4, etc
Local $mod = Mod($len, 3) 
 
; if NOT ( Mod = 1 or 2 AND the last char is hexadecimal, or Mod = 0 AND the last char is '-' )
If not (( ($mod = 1 or $mod = 2) and StringRegExp($char, '[[:xdigit:]]') ) OR _ 
           ($mod = 0 and $char = "-")) Then 
; then remove the last char and write to the input
       GUICtrlSetData($input, StringTrimRight($content, 1)) 

; i.e. if the last character written is in 5th position, then string length = 5, Mod = 2, so this char must be hexa. If it is not then it will not be written
; and so on

I was working on this a while back, wanted to make it a UDF but never put the time to write it to standards.

I used it for quite a few things however.

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

$Form1 = GUICreate("Test GUI", 618, 276, 192, 124)
$Label1 = GUICtrlCreateLabel("Test GUI", 168, 24, 47, 17)
$Button1 = GUICtrlCreateButton("Toggle Validation", 290, 24, 110, 40)
$Input1 = GUICtrlCreateInput("Max 10 Characters", 40, 72, 553, 21)
$Input2 = GUICtrlCreateInput("Numb3rs 0nly", 40, 97, 553, 21)
$Edit1 = GUICtrlCreateEdit("Max 10 Chars Numbers Only + Auto Line Break", 40, 120, 553, 105)
GUISetState(@SW_SHOW)

$iToggle = 1

While 1
 Sleep(10)
 If Mod($iToggle, 2) = 0 Then
;Example 1 Limit to 10 Characters
 _GUIRegExValidate($Input1, "(.{10})(.)", "$1")
;Example 2 Can only type numbers
 _GUIRegExValidate($Input2, "[^\d]", "")
;Example 3 Combind More Than One On Same Input limit to 10 characters, limit to numbers only, line break @ 10 characters to new line
 _GUIRegExValidate($Edit1, "(.{10})(.)", "$1" & @CRLF)
 _GUIRegExValidate($Edit1, "[^\d\r\n]", "")
 EndIf
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            $iToggle = $iToggle + 1
    EndSwitch
WEnd

Func _GUIRegExValidate($sInputLabel, $sRegExCapture, $sRegExReplace)
    $Step1Read = GUICtrlRead($sInputLabel)
    $Step2Validate = StringRegExpReplace($Step1Read, $sRegExCapture, $sRegExReplace)
    If @Extended = 0 Then Return
    GUICtrlSetData($sInputLabel, $Step2Validate)
EndFunc

Func _WM_COMMAND($hWnd, $Msg, $wParam, $lParam)
 _GUIRegExValidate($Edit1, "(.{20})(.)", "$1")
EndFunc

      Hi All:
       How to set the input border color?

      Hello,
      it's quite often, that someone asks how to change the texts of the MsgBox buttons or the InputBox buttons or how to change the position of ta MsgBox. Since years I use CBT hooks for that, but now I made a small UDF out of it for the ease of use. Of course you can build your own GUI or use already existing UDFs to do the same, but I like this way and you can hack (hook) the inbuild InputBox.

      Hello Guys this is my gui and i need the numeric value typed in the highlighted  inputbox. if this value is greater than 1 i need to perform some operations
      \
       
      Here is the summary about that field which i got from wininfo tool

      i tried writing the code as shown below.. but the msgbox is popping up empty value..when the same code is pasted under some button action i am able to access the value present in the field..but when placed alone as written in the attached script i am unable to fetch it... 

      here i am using the valu present in the field

      can you guys tell me what's wrong??? or how can i get that value?

      Hello,
       
      I know you can set flags, e.g. 1, 2, 3 to change the buttons in a MsgBox from "OK" + "Cancel" to "Yes" + "No" + "Cancel", etc...
      However...
      1- Is it possible to manually say what the buttons say? E.g. "Pass" + "Fail"?
      2- Is it possible to do that with an InputBox rather than a MsgBox?
      3- What in your opinion would be better design for the user? A ) Pressing "Fail" on a MsgBox creates a "InputBox" with only a textbox and "Submit" button? B ) Only being able to press "Fail" on an InputBox if the textbox is not empty?
       
      Thank you in advance.

      Hey,
      i would like to set a value into an INPUT field.
      Checked the _IEFormElementSetValue function but that does require _IEFormGetObjByName and this is where the problem comes in. The input field I want to write to is not a part of a form tag. It is part of a table.
      <input type="text" class="w2" id="nabidka_vozidel_formular_tach_od" name="nabidka_vozidel_formular_tach_od" onchange="GLOBAL.pocetInzerceNZ(&quot;nabidka_vozidel_formular&quot;,&quot;tach_od&quot;,&quot;&quot;);" autocomplete="off"> I tried this but that didn't work:
      $oDownloadSamples = _IEGetObjById($oIE, "nabidka_vozidel_formular_tach_od") _IEFormElementSetValue($oDownloadSamples, "123") If you want to try the site I'm working with is https://www.tipcars.cz/. There is a menu on the top left hand side and if you click the "vyhledat" button the input fields will show up.
      Thanks
