_ IEFormGetCollection internal failure

lfast · November 14, 2010

Hi Folks,

I'm a nubie trying to get my feet wet with the _IE.au3 library. I'm following the _IEFormGetCollection sample code to the letter but getting an internal error. Any guesses? Or any guess how I can get some more debugging info? FYI, the page has a form but also has Javascript and Ajax code.

Thanks,

Larry

--------------------------

The Code:

$myPage = _IECreate( "http://www.notTheRealURL.com/")

MsgBox(0, "NewIEwindowStatus","@Error is zero when this box gets displayed:" & @error)

Sleep(2)

$oForms = _IEFormGetCollection($myPage)

MsgBox(9,"This box never appears","Never!")

--------------------------

The Error:

Line 1075 (File "C:\Program Files\AutoIt3\Include\ie.au3"):

Return SetError($_IEStatus_Success, $oTemp.forms.length, $oTemp.forms)

Return SetError($_IEStatus_Success, $oTemp.forms.length^ ERROR

Error: The Requested action with this object has failed.

I'm reasonably sure that it's the _IEFormGetCollection() function that is failing.

-------------------------

The webpage has at least one form on it. But it also has Javascript and Ajax code. Here is an abridged version of the page:

<html>

<head>

...

</head>

<body>

function galaxy_submit(value) {...}

</script>

var ajax = new sack();

var strInfo = "";

function whenResponse () {...}

...

</script>

<form action="galaxy.php?mode=1" method="post" id="galaxy_form"><input type="hidden" id="auto" value="dr">

<table>

<tbody>

<tr><td class="c" colspan="3">Galaxy</td></tr><tr><td class="l">

</form>

It's irrelevant for the user what's causing the issue as long as the issue exists.

This is bug inside IE.au3. Doing

$oTemp.forms.length

...is wrong without checking if $oTemp.forms is actually an object.

If I'm reading you right, the _IEFormGetCollection is either not finding a document or not finding any forms. The latter is most likely. Now that I'm actually reading the _IE library code instead of just complaining :graduated: I can dig a bit deeper into what's going wrong.

Thanks

If there is no forms _IEFormGetCollection doesn't retun an error

#include <IE.au3>

$Url='http://aldo063.free.fr/'
$oIE = _IECreate ( $Url, 0, 0, 1 )
$oForms = _IEFormGetCollection ( $oIE )
For $oForm In $oForms
    ConsoleWrite ( "->--- Form name : " & $oForm.name & @CRLF ) 
Next

_IEQuit ( $oIE )

What's the url you use for get this error ?

lfast · November 14, 2010

The URL won't help you because it's login protected. I attached the HTML source and a zip of the more complete .mht

1galaxy.php.htm

galaxy_mht.zip

I also inserted the following code and got the same error. $oObj.forms is non-zero but forms.length is not allowed. How can I see the type or contents of Objects?

myWin = _IECreate( "http://www.notTheRealURL.com")

$oObj = _IEDocGetObj($myWin)

if 0 = $oObj.forms Then

MsgBox(0,"No Forms","No Forms")

Else

MsgBox(0,"Forms Found?","FormCount=" & $oObj.forms.length )

EndIf

i have tried like this and there is no error...

#include <IE.au3>

$Url='C:\galaxy_mht\1galaxy.php.htm'

$oIE = _IECreate ( $Url, 0, 0, 1 )
$oForms = _IEFormGetCollection ( $oIE )
For $oForm In $oForms
    ConsoleWrite ( "->--- Form name : " & $oForm.name & " Form method : " & $oForm.method & " Form action : " & $oForm.action & @CRLF ) 
    $index = 0
    $oFormElements = _IEFormElementGetCollection ( $oForm )
    For $oFormElement In $oFormElements
        ConsoleWrite ( "+>---           FormElement Index : " & $index & " FormElement Name : " & $oFormElement.name & " FormElement Type : " & $oFormElement.type & " FormElement Id : " & $oFormElement.Id & @CRLF )
        $index += 1
    Next
Next

_IEQuit ( $oIE )

OK, I copied your code and ran it against the html I sent you = FAIL! So this is either a browser problem (as you first suggested) or a problem with my version of AutoIt. So I will try this on another PC.

Thanks for your help!

... the script works fine on my other PC.

Thanks again!
