Date Checking Constraints

2 posts in this topic

Have a function in a script that allows a user to change the date used in the main script (the variable $dtbefore). Problem is that if a user enters a bad date or non date characters the main script will not work. I tried to add some constraints by using the _DateisValid function and that works to a degree. However, the way I have it now the users input is split into an array and spit back out in a format the _DateisValid function can verify. If a user enters rubbish into the input I either get an error about the array being invalid or the script simply does not work correctly.

The only way I can think of to fix this is to have three inputs, one for month, one for day, and one for year, and then put contraints on those as needed.

I have some other scripts I need to write that use dates, so am wondering if there is an easy way to do this. Here is the datechange function of my script.

Func _ChangeDate()
msgbox (0, "","This is the change date function")
GUICreate("Change Date", 400, 140)
$cdate = GUICtrlCreateInput("", 220, 5, 75, 20)
GUICtrlSetState(-1, $GUI_NODROPACCEPTED)
GUICtrlSetLimit(-1, 10)
GUICtrlCreateLabel ( "Enter the date for pdf files you wish to copy", 10, 5)
GUICtrlCreateLabel ( "MM/DD/YYYY", 220, 25)
$btn = GUICtrlCreateButton("Continue", 200, 100, 60, 20)
$btn2 = GUICtrlCreateButton("Exit", 130, 100, 60, 20)
GUISetState()
$msg = 0
While $msg <> $GUI_EVENT_CLOSE
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
        Exit
        Case $msg = $btn2
        Exit
        Case $msg = $btn
            $dtbefore = GUICtrlRead($cdate)
            $chk = StringSplit ($dtbefore, '/', 1)
            $dtentrd = $chk[3] & "/" & $chk[1] & "/" & $chk[2]
                if _DateIsValid($dtentrd) Then
                 msgbox (0, "Valid Date", $dtentrd)
                 $dtbefore = $dtentrd
                 GuiDelete()
                 ExitLoop
             Else
                 msgbox (0, "Invalid Date", "The date must be entered exactly in the MM/DD/YYYY format.  Please try again")
                 guidelete()
                 _ChangeDate()
                 endif
            ExitLoop
    EndSelect
    Wend
EndFunc
