IE automation seems to fail randomly

[tahilaci]

My original intention is to use tfl journey planner programmatically so that I can see if there are any planned delays or diversions when I go to work in the next week or month. This simplified code opens the website and fills in the form, presses "Plan Journey" reads the tables with the information in them and goes back to the previous page in a loop. This usually works. However the code execution stops randomly. At the very end it should close IE (if that doesn't happen you know it failed). When I run it usually it completes a few iterations and fails after.

Could you tell me what causes it to stop?

(Please change the date in the third line so that it shows tommorow's date before you test it. The website doesn't work if the inquiry date or time is in the past.)

It's all code from here: (I don't know how to put it)

#include <ie.au3>  

#include <Array.au3>;Only to display the table

local $numberofRepetitions = 7

local $var

local $tableCells

local $cell

local $interchange

local $StartPoint, $destination, $Jdate, $Jtime

$startPoint = "Marble arch"

$Destination = "London Victoria"

$Jtime = "21:50"

$Jdate = "31/07/2013"

 

$oIE = _IECreate ("http://journeyplanner.tfl.gov.uk/user/XSLT_TRIP_REQUEST2?language=en")  

 

 

for $maincounter = 1 to $numberofRepetitions step 1

   

$oForm = _IEFormGetObjByName ($oIE, "jp_form")  

$oQuery1 = _IEFormElementGetObjByName ($oForm, "startpoint")  

$oQuery2 = _IEFormElementGetObjByName ($oForm, "endpoint")

$oQuery3 = _IEFormElementGetObjByName ($oForm, "jp-time")  

$oQuery4 = _IEFormElementGetObjByName ($oForm, "datepicker") 

 

 

_IEFormElementSetValue ($oQuery1, $startpoint)

_IEFormElementSetValue ($oQuery2, $destination)

_IEFormElementSetValue ($oQuery3, $jtime)

_IEFormElementSetValue ($oQuery4, $jdate)

 

_IELoadWait($oIE,0) 

$oButtons = _IETagnameGetCollection($oForm, "input")

For $oButton in $oButtons

    If String($oButton.value) = "Plan Journey" Then

_IEAction($oButton, "click")

        ExitLoop

    EndIf

 Next

_IELoadWait($oIE,0)

 

 

 

;~ ;display table contents

for $var = 0 to 0 step 1

$oTable = _IETableGetCollection ($oIE, $var)

 

$aTableData = _IETableWriteToArray ($oTable, True)

$aTableData[1][0]= $Jdate

;_ArrayDisplay($aTableData)

next

_IELoadWait($oIE,0)

 

 

_IEAction($oIE, "back")

_IELoadWait($oIE,0) 

 

next

 

_IEQuit($oIE)

Hi, tahilaci, welcome to the forum.

First and foremost, I see no error checking at all. How are you checking to determine where and what causes the script to fail? When it fails, what is the output to the console? Have you looked at _IEErrorHandlerRegister or _IEErrorNotify in the Help file?

As we oft say here - help us help you. We need more than "fails randomly, please tell me why"

I didn't know how to do error checking, because I'm new to Autoit. I will have a look at it.
