Refresh and execute a program in Autoit - autoit

Question

I want to make a program in autoit with a GUI - 2 buttons: the first button must refresh a web page (Ex: Google page) every 3 seconds, the second button must stop the refresh and do some operations on the web page. I'm ok with the first button, but I cannot exit from the loop with the second button and execute the operation I want. Can someone help me? Thanks a lot! This is the code:
#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <GDIPlus.au3>
$Form1 = GUICreate("Example", 190, 133, 192, 124)
GUISetBkColor(0xFFFF00)
$Button1 = GUICtrlCreateButton("UPDATE", 3, 31 ,179, 37, 0)
$Button2 = GUICtrlCreateButton("EXECUTE", 3, 80 ,179, 37, 0)
GUICtrlSetColor(-1, 0x0000FF)
GUICtrlSetBkColor(-1, 0x00FF00)
GUICtrlSetCursor (-1, 0)
GUICtrlSetColor(-1, 0x000000)
GUISetState(#SW_SHOW)
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
Case $button1
HotKeySet("{x}", "_Exit") ; Sets a shortcut to kill the script quickly. ESC
Opt("WinTitleMatchMode", 3) ; This is to tell the script to only refresh the EXACT window, incase there are similar windows. Such as: Window 1, Window 2.
While 1 ; This begins a While LOOP
Sleep(3000) ; Tell the script to pause for 3 seconds
$title = WinGetTitle("Google - Mozilla Firefox", "") ; Grabs the exactly title and saves it to a variable to do an If statement against.
If WinExists($title) Then ; Check to see if the desired window is running.
WinActivate($title) ; If it is running, first activate the window.
WinWaitActive($title) ; This tells the script to not send the refresh key (F5) until the window has appeared.
Send("{F5}") ; This sends the F5 key to refresh the window.
Else ; This is an else statement to tell the script to do a different operation if the window is not running.
Sleep(10) ; Just a filler item to wait until the desired window is running.
EndIf ; End the If statement to continue the script.
WEnd ; Close the While LOOP
Func _Exit() ; This is the function that is linked to the kill switch, ESC. It tells the script to perform the following actions.
ExitLoop ; Block pressing "x"
EndFunc ; Close the function up.
Case $button2
ExitLoop ; stop the loop and make operations below
Send("{TAB}")
Send("^v")
EndSwitch
WEnd

Something like this?
#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <GDIPlus.au3>
Global $Go2 = True
$Form1 = GUICreate("Example", 190, 133, 192, 124)
GUISetBkColor(0xFFFF00)
$Button1 = GUICtrlCreateButton("UPDATE", 3, 31, 179, 37, 0)
$Button2 = GUICtrlCreateButton("EXECUTE", 3, 80, 179, 37, 0)
GUICtrlSetColor(-1, 0x0000FF)
GUICtrlSetBkColor(-1, 0x00FF00)
GUICtrlSetCursor(-1, 0)
GUICtrlSetColor(-1, 0x000000)
GUISetState(#SW_SHOW)
Local $hTimer = TimerInit()
While True
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
Case $Button1
$Go2 = True
HotKeySet("!{e}", "_Exit") ; Sets a shortcut to kill the script quickly. ESC
HotKeySet("{s}", "_ExitLoop") ; Sets a shortcut to kill the script quickly. ESC
Opt("WinTitleMatchMode", 3) ; This is to tell the script to only refresh the EXACT window, incase there are similar windows. Such as: Window 1, Window 2.
While $Go2 ; Avoid getting stuck in the while loop forever
If TimerDiff($hTimer) > 3000 Then
ConsoleWrite("Refreshing Mozilla" & #LF)
$title = WinGetTitle("Google - Mozilla Firefox", "") ; Grabs the exactly title and saves it to a variable to do an If statement against.
If WinExists($title) Then ; Check to see if the desired window is running.
WinActivate($title) ; If it is running, first activate the window.
WinWaitActive($title) ; This tells the script to not send the refresh key (F5) until the window has appeared.
Send("{F5}") ; This sends the F5 key to refresh the window.
$hTimer = TimerInit()
HotKeySet("{x}")
Else ; This is an else statement to tell the script to do a different operation if the window is not running.
;~ Sleep(10) ; Just a filler item to wait until the desired window is running.
EndIf ; End the If statement to continue the script.
EndIf
WEnd
$hTimer = TimerInit()
HotKeySet("{x}") ; Release hotkey
HotKeySet("!{e}") ; Release hotkeys
ConsoleWrite("Exited loop" & #LF)
Case $Button2
;you can't exit the loop from the $button1 here but there is a hotkey set to exit it, ALT + E
Send("{TAB}")
Send("^v")
EndSwitch
WEnd
Exit
Func _Exit()
Exit
EndFunc ;==>_Exit
Func _ExitLoop()
$Go2 = Not $Go2
EndFunc
P.S. I avoid using sleep because it pauses the script.

This is how I would do it.
Local $Refresh = 0 ; Set refresh OFF
Local $Timer = TimerInit()
Local $RefreshEvery = 3 ; seconds
Do
$msg = GUIGetMsg()
Select
Case $msg = $BtnRefresh
$Refresh = 1 ; Set refresh ON
Case $msg = $btnStop
$Refresh = 0 ; Set refresh OFF
EndSelect
If $Refresh And (TimerDiff($Timer) > $RefreshEvery*1000) Then
RefreshBrowser()
$Timer = TimerInit()
EndIf
Until $msg = $GUI_EVENT_CLOSE
