Restrict Edit UDF and HH:MM AM/PM

Recommended Posts

ijourneaux

I am not very knowledge with RegEx expressions so I am having difficulty using the Restric Edit UDF to control limit the user to a HH:MM am/pm formatted entry.

Is there a source of examples? that I would be able to model after?

For the purposes of REstrict Edit what would the correct regex string be?

ijoureaux,

The author of that thread has not been on in awhile.  Here's an example of how it might be done. 

#include <GUIConstants.au3>
#include <EditConstants.au3>
#include <WindowsConstants.au3>
#include <winapi.au3>

GUICreate('MyGUI', 300, 200)
guictrlcreatelabel('Enter Time in HH:MM AM|PM format',10,10,200,20)
$edit = GUICtrlCreateInput('', 10, 30, 120, 30)
guictrlsetfont(-1,16)
$warn = guictrlcreatelabel('',10,160,180,30)
guictrlsetcolor(-1,0xaa0000)
GUIRegisterMsg($WM_COMMAND, 'WM_COMMAND')
GUISetState()

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    Switch BitAND($wParam, 0xFFFF)
        Case $edit
            Switch BitShift($wParam, 16)
                Case $EN_update
                    guictrlsetdata($warn,'')
                    switch stringlen(guictrlread($edit))
                        case 1,2
                            if not stringisdigit(guictrlread($edit)) then
                                guictrlsetdata($edit,'')
                                guictrlsetdata($warn,'Chars 1 and 2 must be numeric')
                            EndIf
                        case 3
                            if not stringregexp(guictrlread($edit),'\d\d\:') then
                                guictrlsetdata($edit,stringtrimright(guictrlread($edit),1))
                                guictrlsetdata($warn,'3RD char must be a :')
                            EndIf
                        case 4
                            if not stringregexp(guictrlread($edit),'\d\d\:\d') then
                                guictrlsetdata($edit,stringtrimright(guictrlread($edit),1))
                                guictrlsetdata($warn,'4TH char must be a numeric')
                            EndIf
                        case 5
                            if not stringregexp(guictrlread($edit),'\d\d\:\d\d') then
                                guictrlsetdata($edit,stringtrimright(guictrlread($edit),1))
                                guictrlsetdata($warn,'5TH char must be a numeric')
                            EndIf
                        case 6
                            if not stringregexp(guictrlread($edit),'\d\d\:\d\d ') then
                                guictrlsetdata($edit,stringtrimright(guictrlread($edit),1))
                                guictrlsetdata($warn,'6TH char must be a space')
                            EndIf
                        case 7
                            if not stringregexp(guictrlread($edit),'(?i)\d\d\:\d\d a|p') then
                                guictrlsetdata($edit,stringtrimright(guictrlread($edit),1))
                                guictrlsetdata($warn,'7TH char must be an "a" or "p"')
                            endif
                        case 8
                            if not stringregexp(guictrlread($edit),'(?i)\d\d\:\d\d (a|p)m') then
                                guictrlsetdata($edit,stringtrimright(guictrlread($edit),1))
                                guictrlsetdata($warn,'8TH char must be an "m"')
                            endif
                    endswitch
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_COMMAND

There might be a way to edit the input using one SRE but I don't speak Klignon that well.

Another possibility is to use a date control.

Another possibility is to use a date control.

 

Or use 2 combos to enter hour and min 

@kylomas

This one will accept 24h format without am/pm, but will force to add am/pm if 12h format

$txt = "05:18 pm"  ; "5:18 am"  ; "00:15" ; "23:48"  ; "13:35" ; "12:45"  ; valid
;$txt = "05:18"  ; "13:15 am"  ; "12:35 pm" ; "00:15 am"  ; "22:35 pm"    ; invalid   

$res = StringRegExp($txt, '(?ix)^\h*(((((0?[1-9])|(1[01])):([0-5]\d))(\h*[ap]m))|(((0?0?)|(1[2-9])|(2[0-3])):[0-5]\d))\h*$' )

Msgbox(0,"", $res)

:)

@mikell - Thanks.  I believe that PhoenixXL's code is based on either subclassing the control or operating on EN_UPDATE.  Since the OP referred to that code I assumed that he wanted a character by character edit.

@ijouneaux - If you do NOT want character by character editing then mikell's SRE can be applied to the whole pattern in the message loop.

Honestly, a simpler way (using combos) is better by far, the digits checking is tricky  :mellow:

Agreed, but that is not the road the OP started down.

PhoenixXL's UDF needs to define patterns to be used for char by char checking and this will be tricky if a time format (12 or 24h) is not forced

Again agreed...

Directly from the Help file for date contorl...

#include <DateTimeConstants.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

Example()

Func Example()
    GUICreate("My GUI get time", 200, 200, 800, 200)
    Local $idDate = GUICtrlCreateDate("", 20, 20, 100, 20, $DTS_TIMEFORMAT)
    GUISetState(@SW_SHOW)

    ; Loop until the user exits.
    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop

        EndSwitch
    WEnd

    MsgBox($MB_SYSTEMMODAL, "Time", GUICtrlRead($idDate))
    GUIDelete()
EndFunc   ;==>Example

If the user does NOT need char by char editing then I believe this is the simplest way  (the second can be striped off if needed)

As the OP mentioned "limit the user to a HH:MM am/pm formatted entry"  this GuiCtrlCreateDate way is - IMHO - the best one  :)
