How to exit in the loop

[dannydy]

Hello guys, need some simple help here.

Global $site = "http://www.bing.com"
Global $up= Ping("www.bing.com")

HotKeySet("{ESC}", "_Exit")

if $up = 0 Then
   $msg = GUIGetMsg()
   do
   $up= Ping("www.bing.com")
   sleep(2000)
   Until $up <> 0 or $msg = $GUI_EVENT_CLOSE Or $msg = $Cancel


Func _Exit()
    Exit
 EndFunc   ;==>_Exit

This is my coding, when the interface started and when there's no network connection, it will keep looping until there's network connection. While in the looping, when click on the GUI cancel button or window close event, the script will stop running and exit. My problem here's i couldnt click the cancel button nor the window close event to exit. I only managed to press the "{ESC}" to terminate the script. Appreciate someone can help me. i tried many times but i failed and gave up.

Look at where $msg = GUIGetMsg is. This should give you a clue as to why it doesn't detect a click when in the loop.

Also use Tidy (Ctrl + T) on your code, for easier readability.

Actually i had tried to put the $msg = GUIGetMsg inside the loop, but still unable to exit.

Have you thought about using OnEventMode? Or would you mind providing functional code so I don't have to create a GUI.

I believe the sleep function is preventing messages sent from the GUI. Reducing the sleep time to 10ms may be one possible solution - you can still ping every two seconds if you think about it. I strongly recommend reading the following excellent article in wiki:

The messages from the GUI are queued but not processed because Sleep can't be interrupted.

abundant thanks to all of you for the sharing and valuables input, i managed to get it worked perfectly based on the example at above article(OnEvent mode). but the messageloop mode is abit complicated for me, couldnt understand how's work at all.

I admit it is a little complicated at first, but it will get easier once you get used to these methods. Well done in solving it yourself. The more effort you put in, the more you learn. Thanks for updating us on your progress, and I'm glad you got it working.

Provide a small GUI that's runnable and I will show you one way.
