ping loop help

9 posts in this topic

I know this should probably be basic programming but I am having an issue with this. I am trying to create a simple app that pings a server to tell if it is up or not. if it is up it puts a checkbox image and if is not reachable it is given an x image. My code seems to work fine but I cant get the window to close when I click the close "x". It seems like it is too busy to close it or something. Sorry for the probably noob question.

#include <INet.au3>
#include <GUIConstantsEx.au3>

GUICreate("Hello World", 300, 300) 


$buttonServer1 = GuiCtrlCreatePic("C:\Users\Administrator\Desktop\ping server test\Exclamation.bmp",110,0, 0,0)


GUISetState()


$i = 0
While 1
    $var = Ping("www.google.com")
    If $var Then; also possible:  If @error = 0 Then ...

  
        GUICtrlSetImage($buttonServer1, "C:\Users\Administrator\Desktop\ping server test\CheckMark.bmp")
        GUISetState()

            $i = $i + 1
            Sleep(10000) ;two seconds

    Else
       
        GUICtrlSetImage($ButtonServer1, "C:\Users\Administrator\Desktop\ping server test\Failed.bmp")
        GUISetState()

            $i = $i + 1
            Sleep(10000) ;two seconds

    EndIf
    

WEnd

help file:

Ping ( "address/hostname" [, timeout] )

its better set timeout, to minimize delay!

this code from somewhere in forum

ConsoleWrite(_ping("http:\\www.google.com")); test 1


Func _ping($host)
    $var = Ping($host,250)
    If $var Then  Return $var & "/ms"& @CRLF
    Switch @error
        Case 1 
            Return "Host is offline" & @CRLF
        Case 2 
            Return "Host is unreachable"& @CRLF
        Case 3 
            Return "Bad destination"& @CRLF
        Case 4 
            Return "Other errors"& @CRLF
    EndSwitch
EndFunc

btw, this one what i use to checking connection, maybe can help

#Region _isconnect2host
Func _isconnect2host($svHost, $ivSleepTime = 250)
InetGet($svHost, @TempDir&"\foo.html",1,1)
While @InetGetActive
    ConsoleWrite("Downloading: Bytes = " & @InetGetBytesRead & @CRLF)
        If @InetGetBytesRead > 0 Then
            Return True
        EndIf
    Sleep($ivSleepTime)
Wend 
    Return False
EndFunc
#EndRegion

i did put that in but it had no effect on being able to close the window.

im on a win 7 pro machine if that makes a difference

add these lines into the while loop:

$msg = GUIGetMsg()
If $msg = $GUI_EVENT_CLOSE Then Exit

I took out the sleep commands and the gui doesnt lock up now. However I would still like the script to pause for a certain number of seconds between ping polls.

Instead of using sleep(x) use something like this instead

$Timer = TimerInit)
While 1
    $var = Ping("www.google.com")
    $Delay = TimerDiff($timer)
    If $Delay >= 2000 Then  ;2 seconds delay check
        If $var Then; also possible:  If @error = 0 Then ...
           GUICtrlSetImage($buttonServer1, "C:\Users\Administrator\Desktop\ping server test\CheckMark.bmp")
           GUISetState()
           $i = $i + 1
        Else
          GUICtrlSetImage($ButtonServer1, "C:\Users\Administrator\Desktop\ping server test\Failed.bmp")
          GUISetState()
          $i = $i + 1
        EndIf
        $Timer = TimerInit()
   Endif
WEnd

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

this does the trick thanks! it does run the processor a little high but not a deal breaker.

Change this :

Endif
Wend

To This:

Endif
    Sleep(10)
Wend

It will decrease the CPU load immensely and still let you break out of it using the onevent function calls.
