Getting the name of a button on the menu item failed even though the menu was displayed in the event

[Loc]

Allow me to greedily ask 2 questions:
1> When putting guictrlcreatemenuitem in the function and catching the event, does it consume ram resources? Every time I load the menuitem, it cannot read the changed button name.

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

Opt('GUIOnEventMode', 1)
Global $Button1
$GUI = GUICreate("Test Menu", 349, 222, 192, 124)
$Button1 = GUICtrlCreateButton("Button Show Menu", 96, 56, 131, 81)
GUISetOnEvent($GUI_EVENT_CLOSE, '_Exit')
GUISetOnEvent($GUI_EVENT_SECONDARYUP, "_SecondaryUp")
GUISetState(@SW_SHOW)

While 1
WEnd

Func _SecondaryUp()
    $aCInfo = GUIGetCursorInfo($GUI)
    Switch $aCInfo[4]
        Case $Button1
            _ShowMenu()
    EndSwitch
EndFunc   ;==>_SecondaryUp

Func _ShowMenu()
$CtMenu = GUICtrlCreateContextMenu($Button1)
$Event = GUICtrlCreateMenuItem(GUICtrlRead($Button1), $CtMenu)
GUICtrlSetOnEvent($Event, '_RMenu')
EndFunc

Func _RMenu()
GUICtrlSetData($Button1, 'Button Show Menu '& Random(0, 99, 1))
EndFunc

Func _Exit()
    Exit
EndFunc

2> I have an order of: 0000000000(10 zeros)
When there is the first order, then: 0000000001 (9 numbers 0 and 1)
When the order is up to 10, then 0000000010(8 zeros and 10s)
I searched but nothing came up so I did this:
$job = 0000000000
If StringLen($job) > 10 Then StringRight($job, 10)
Is there any better function? I don't find it effective

[JockoDundee]

Instead of 

If StringLen($job) > 10 Then StringRight($job, 10)

don’t you want

If StringLen($job) > 10 Then $job = StringRight($job, 10)

or some other assignment, otherwise it does nothing.

Thank you JockoDundee! Here is me cut out the example style. Normally, use Guictrlsetdata() guictrlread() when working on the gui. I'm looking for a function that can always add up, for example: 0001 + 0002 = 0003 0010 + 0020 = 0030 0100 + 0200 = 0300 1000 + 0100 = 1100 like that

1>

Func _ShowMenu()
    Local Static $CtMenu    ; <-- added
    GUICtrlDelete($CtMenu)  ; <-- added
    $CtMenu = GUICtrlCreateContextMenu($Button1)
    $Event = GUICtrlCreateMenuItem(GUICtrlRead($Button1), $CtMenu)
    GUICtrlSetOnEvent($Event, '_RMenu')
EndFunc   ;==>_ShowMenu

2>

StringFormat("%010s", $iYourNumber) ; <-- formats $iYourNumber as 10 chars with leading zero

1> It seems to be 1 or 2 beats slower

it's not slower, it shows "previous button title" because in the logic of your script, you first read the title of the button and after you set a new name to the the button, so you get "one title on late"
