_IE.au3 Help with Error Handling

[danrche]

Hello All,

I'm trying to figure out how to handle errors with this code, and in general. I've read a bit on the references and welcome any other sources that would help. Here's my issue, the below code works most of the time, but sometimes it gives "Return SetError($_IEStatus_Success, 0, $o_object.document.body.innerText)" Error stating Variable must be of type "Object". What's the best practice method for error handling?

Code for review:

#comments-start

Created to alert for off-line servers from RMM tool, will later build in escape functions to exit the loop. End result should be every 1 min to check for off-line Servers and speak them outloud. This is for the most part for me to learn how to code.

#comments-end

#include <IE.au3>

$quit = 0

While $quit = 0

_Test()

Sleep(100)

WEnd

Func _Test()

$oIE = _IECreate("http://my RMM tool website here")

$frames = _IEFrameGetCollection($oIE);

$numFrames = @extended ; number of frames

If @error Then

_IEQuit($oIE)

EndIf

For $i = 0 to ($numFrames -1)

$oFrame = _IEFrameGetCollection($oIE, $i)

$xi = _IEBodyReadText($oFrame)

$myArray = StringSplit($xi, @CR , 2)

For $g In $myArray

If StringInStr($g, "offline", 0) <> 0 Then

$t = StringTrimLeft($g, 23)

_IEQuit($oIE)

_talk($t)

EndIF

Next

Next

EndFunc

Func _talk($sText)

AutoItSetOption("RunErrorsFatal",0)

SoundSetWaveVolume(100)

$WshShell = ObjCreate("SAPI.spVoice")

$WshShell.Speak ($sText)

EndFunc

Suggest you simply add _IELoadWait($oFrame) into your code just prior to the _IEBodyReadText call.

Verify $oFrame is valid with with IsObj($oFrame) before you try "$xi = _IEBodyReadText($oFrame)".

Edit: Ooh, good idea from Dale while I was typing...

Awesome, thanks guys, I'll give that a try. Thanks for pointing me in the right direction.

YES!!! IT WORKS!!! Thanks again guys, I used the _IELoadWait($oFrame) suggestion and it clicks evertime now. now I can get busy on building this in as an app with systray and escape keys.
