Would you be so kind in posting your script? We do not have mind reading capabilities nor can we hack into your PC to read your code. Without your script, we have no idea how to help you.

I searched the forum for a similar example and found one by martin and modifed it to perform about how you would like. The only problem with this code is backspacing to delete the "." does not work. I'm trying to figure it out.

Here's what I have so far:

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

GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

$gui = GUICreate("Gui", 300, 100)

$IP = GUICtrlCreateInput("", 10, 40, 200, 22, $ES_NUMBER)
GUICtrlSetLimit($IP, 6)

GUISetState()


While 1
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd

Func WM_COMMAND($hWnd, $msg, $wParam, $lParam)
    $nNotifyCode = BitShift($wParam, 16)
    $nID = BitAND($wParam, 0x0000FFFF)
    If $nID = $IP Then
        $hCtrl = $lParam
        If $nNotifyCode = $EN_CHANGE Then
            $txt = GUICtrlRead($IP)
                If StringLen($txt) = 3 Then
                    $newtxt = $txt & "."
                    GUICtrlSetData($IP, $newtxt)
                EndIf
        EndIf
    EndIf
    Return $GUI_RUNDEFMSG
EndFunc

I think this will work:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <editconstants.au3>
#include <Misc.au3>

GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

$gui = GUICreate("Gui", 300, 100)

$IP = GUICtrlCreateInput("", 10, 40, 200, 22, $ES_NUMBER)
GUICtrlSetLimit($IP, 6)

GUISetState()


While 1
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd

Func WM_COMMAND($hWnd, $msg, $wParam, $lParam)
    $nNotifyCode = BitShift($wParam, 16)
    $nID = BitAND($wParam, 0x0000FFFF)
    If $nID = $IP Then
        $hCtrl = $lParam
        If $nNotifyCode = $EN_CHANGE Then
            $txt = GUICtrlRead($IP)
                Local $hDLL = DllOpen("user32.dll")

                If _IsPressed("08", $hDLL) AND StringLen($txt) = 4 Then
                    $newtxt = StringTrimRight($txt, 1)
                    GUICtrlSetData($IP, $newtxt)
                ElseIf StringLen($txt) = 3 Then
                    $newtxt = $txt & "."
                    GUICtrlSetData($IP, $newtxt)
                EndIf
        EndIf
    EndIf
    Return $GUI_RUNDEFMSG
EndFunc

Local $sFloat = "123.45"

If StringRegExp($sFloat, "\A\d{3}\.\d{2}\z") Then MsgBox(0, "Msg", $sFloat & " = Valid Input")

Its working.   

 

 Thanks

The regular expression should work. I didn't try abberration's code, but I think it's much easier to allow the user to type whatever they like and only validate the input after they click the Okay button. Good luck with it.
