Problem with _IEGetObjByName

[setirich]

I have a script that generates this message after exactly 30 cycles or pages. For the past week it was working just fine, and then last night began the behavior again. As you can see, its an error within the IE.au3 include.

"C:\Program Files (x86)\AutoIt3\Include\IE.au3" (1875) : ==> The requested action with this object has failed.:
If IsObj($oObject.document.GetElementsByName($sName).item($iIndex)) Then
If IsObj($oObject.document^ ERROR

The code that calls & uses this information is below...nothing fancy, but why does it fail after exactly 30 cycles ?  Not even sure its my code that is failing...or the include.

$InBox = _IEGetObjByName($oIE, "CaseNumber")
_IEAction($InBox, "focus")
$msgIS = _IEFormElementSetValue($InBox, $PID)
$SButt = _IEGetObjByName($oIE, "submit")
_IEAction($SButt, "focus")
_IEAction($SButt, "click")

I'm using the latest stable version of  AutoIt (v3.3.14.2)

The system is Widows 7 with IE 11. Both have all the latest updates.

Thanks for any insight you might offer...

On my website I have an algorithm that drops rapid multiple connections that are similar -  do you have delays are you using _IENavigate after the first _IEAttach or _IECreate ?

@setirich do you use COM Error Handler ?

Please read this:  How to use IE.au3  UDF with  AutoIt v3.3.14.x

to Jury:

• Yes I have delays in my script. I don't want to bang the web site. there is approx. 6 seconds of delay per page. I did not show the delays so the 'action' code would be clear.
• After the initial attach, there are additional navigate commands to return to the case number input and submit page. The action 'back' command did not work, so I set it up with the navigate command. Is that wrong?
• I'm staying at the same web site most of the time. (big Calf. courts)
• I'm using the user interface 'properly'. I scrape court case info for various groups of attorneys and they don't want me ruffling the local court feathers.
• No, I don't use com error handling, I will look into it immediately.

to  mLipok:

• Thanks for writing the 'how to' instruction. I will work this into my web scripts. I believe the problem I'm having is 'internal' and not related to the web site trying to bounce me out. The returned error is an internal AutoIt once, so the com thing may be just what is needed.

That is a nasty thing - you will need to put a checkpoint after every IE function call because you get an internal IE include error line - right ?

So i would suggest to put a filewriteline after each IE call to write status reports and later on check what and where it went wrong.

When you do it , get back and say if this issue  still occurs in your case.

Juvigy:

I do NOT get an error with each function call. Only after a period of time...so many pages.

I'm not sure why using IE functions are nasty, but I'd like to hear more.

mLipok:

Interesting result with your example script: 

On my Workstation, Using it script exactly as presented, it properly clicks on the btnI and returns a page about the days Google logo. No com error

On the machine I use for running web scripts, it returns a com error as it should within the console.

Both machines are WIn7Pro, all latest updates, same IE11 version, and same AutoIt version. This is not the first time I've seen different reactions to scripts / MySQL code / VB programs between machines. Always makes me wonder why computers sometimes seem so random in their behavior...

Still, I need to incorporate the com error handling. I'm NOT a pro at this, although I use AutoIt extensively for text manipulation, my web skills have always been suspect...so please bear with me as I attempt to learn.

I am currently attempting to figure out how to put these checks into my script, but give my above statement on skill level, it's going to be an interesting & challenging day.
