Pause Script - OnEventMode

[enaiman 15]

Sorry for opening another topic with this subject - I did a search for "pause" and read alot of previous topics; I guess people get jumpy about this topic ... and they are right because many could be avoided with a minimum research.

I'm working on a script which does configuration changes on a big number of network switches (the IP are read from an ini file)

The fact is - once I start the process I cannot pause or stop it - it will go on until there is a login error or the end of IP list is reached)

Here is the code of the main function

expandcollapse popup

Func main_func()
    Do
        $current_ip = IniRead($ip_ini, "IP", "ip"&$current_ipno, "")                    ;read the current IP
        $tterm_ttl = $current_ip&" - Tera Term VT"                          ;
        $delay = Ping($current_ip)+Ping($current_ip)+Ping($current_ip)+Ping($current_ip)
        $sw_string = ""
        $begin_time = TimerInit()
        ;first login - creating the temp admin account
        $tterm = Run($teraterm&" "&$current_ip&" /L=teraterm.log")
        Sleep (2000)
        WinWait($tterm_ttl, "")
        WinActivate ("Secure Password Changer", "")
        login("admin", $adminpwd)
        read_last($tterm_log)
        If StringInStr ($lastline_content, "*") Then
            $sw_string = StringMid($lastline_content, 3, 10)
        Else
            $sw_string = StringLeft($lastline_content,10 )
        EndIf
        ControlSend($tterm_ttl,"", "","create account admin temp "&$temppwd&@CR)
        wait_prompt ("#")
        update_status($sw_string&" Temp admin account created.")
        ControlSend($tterm_ttl,"", "","logout"&@CR)
        wait_prompt ("(y/n)")
        ControlSend($tterm_ttl,"", "","n"&@CR)
        Do 
            Sleep(200)
        Until Not WinExists($tterm_ttl, "")
        ;second login - verifying the temp admin account and changing admin password
        $tterm = Run($teraterm&" "&$current_ip&" /L=teraterm.log")
        WinWait($tterm_ttl, "")
        WinActivate ("Secure Password Changer", "")
        login("temp", $temppwd)
        update_status($sw_string&" Temp admin account verified.")
        ControlSend($tterm_ttl,"", "","configure account admin "&$newadminpwd&@CR)
        wait_prompt ("#")
        update_status($sw_string&" Admin password changed.")
        ControlSend($tterm_ttl,"", "","logout"&@CR)
        wait_prompt ("(y/n)")
        ControlSend($tterm_ttl,"", "","n"&@CR)
        Do 
            Sleep(200)
        Until Not WinExists($tterm_ttl, "")
        ;third login - verifying new account password and deleting the temp admin account
        $tterm = Run($teraterm&" "&$current_ip&" /L=teraterm.log")
        WinWait($tterm_ttl, "")
        WinActivate ("Secure Password Changer", "")
        login("admin", $newadminpwd)
        update_status($sw_string&" New admin password verified.")
        ControlSend($tterm_ttl,"", "","delete account temp "&@CR)
        wait_prompt ("#")
        update_status($sw_string&" Temp admin account deleted.")
        ControlSend($tterm_ttl,"", "","logout"&@CR)
        wait_prompt ("(y/n)")
        ControlSend($tterm_ttl,"", "","n"&@CR)
        update_status($sw_string&" Saving configuration.")
        Do 
            Sleep(200)
        Until Not WinExists($tterm_ttl, "")
        GUICtrlSetData ($switches, Int (GUICtrlRead($switches))+1)      ;update number of switches processed
        $current_ipno +=1                       ;go to next IP on the list
        $end_time = TimerDiff($begin_time)              ;get the time spent on the switch
        $time_spent += $end_time                    ;get the whole time
        $average_time = $time_spent/Int (GUICtrlRead($switches))        ;get the average
        $average_time = Round($average_time)                ;get rid of decimals
        time_format()
        GUICtrlSetData ($avg_time, $swtime)         ;display the time
        If $current_ipno > IniRead($ip_ini, "IP", "ip_count", "") Then  ;if the last IP was processed
            update_status(" ALL passwords changed.")
            FileClose ($process_log)
            Return                                                      ;get out of this routine
        EndIf
    Until $status_flag = 1 Or $temp_flag = 1
    
EndFunc

What could really solve my problem wouldn't be a real "pause" but a way to set $status_flag or $temp_flag to 1 and this will end the main function (after the function is completed) I want to accomplish this by pressing a button. I know it is difficult and I can't imagine a way to do it (I don't wat to use the HotKeySet solution to pause the script).

I imagine that OnEventMode is not the easiest way to do this but unfortunately it is to late to do it.

Any answer is highly appreciated.

It's not that mysterious. Here is a much shorter script for a demo:

expandcollapse popup

#include <guiconstants.au3>
Opt("GuiOnEventMode", 1)
Global $RunFlag = 0, $Cycles = 0

; Create GUI
$hGUI = GUICreate("Pause Demo", 220, 120)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Quit")
$Label_1 = GUICtrlCreateLabel("Cycles of main_func() completed: 0", 20, 20, 180, 30, $SS_CENTER)
$Button_1 = GUICtrlCreateButton("START", 20, 70, 50, 30)
GUICtrlSetOnEvent(-1, "_ButtonHit")
$Button_2 = GUICtrlCreateButton("PAUSE", 90, 70, 50, 30)
GUICtrlSetOnEvent(-1, "_ButtonHit")
$Button_3 = GUICtrlCreateButton("ABORT", 160, 70, 50, 30)
GUICtrlSetOnEvent(-1, "_ButtonHit")
GUISetState()

While 1
    If $RunFlag Then main_func()
    Sleep(100)
WEnd

Func _ButtonHit()
    Switch @GUI_CtrlId
        Case $Button_1
            $RunFlag = 1
        Case $Button_2
            $RunFlag = 0
        Case $Button_3
            Exit
    EndSwitch
EndFunc

Func main_func()
    GUICtrlSetData($Label_1, "Cycles of main_func() completed: " & $Cycles)
    $Cycles += 1
    Sleep(500)
EndFunc   ;==>main_func

Func _Quit()
    Exit
EndFunc   ;==>_Quit

Great example

Thank you

I've noticed you used @GUI_CtrlId - is this macro supposed to work on 3.2.2.0 or beta and not on 3.2.1.0? When trying to use it on 3.2.1.0 I get an error "Macro unknown" so I imagine that I should use a newer version ... heh ... here comes another dilemma because of ControlSend which doesn't work properly on 3.2.2.0 and beta .

Anyway - You gave me a solution and I am grateful.

Thank you again.

Edited:

Tested it and it works great - I don't get errors about @GUI_CtrlId anymore.

You have my eternal gratitude.
