# IE.au3 and other object errors

## Recommended Posts

This is my first time using IE.au3, so it's possible i'm missing something simple, but here is my issue:

First, i'm using IE.au3 version T2.0-0.

I'm also using the latest beta of AutoIt, version 3.1.1.125

I have a web page in which i want to click a link. _IELinkClickByText() seems like the perfect solution.

Initially i was getting an error saying the link did not exist. After some research i found that my link is actually

inside a frame, and that i might want to send the frame object into _IELinkClickByText() instead of the IE object.

So i used _IEFrameGetObjByName() in an attempt to get the frame, but that fails with the following error:

>Running:(3.1.1.125):C:\Program Files\AutoIt3\beta\autoit3.exe "J:\autoit\src\IETests.au3"
J:\autoit\lib\IE.au3 (884) : ==> The requested action with this object has failed.:
If IsObj($o_object.document.parentwindow.frames ($s_Name, $i_index)) Then If ^ ERROR The exact code used was: $oFrame = _IEFrameGetObjByName ($oIE, "_svf0") _IELinkClickByText ($oFrame, "Administration - Product",1)

I have no idea how to go about figuring out what is wrong here.

I have also run into some other problems.

I tried to use a piece of code from the IE.au3 help file to step over all frames in my document.

The code was:

$oFrames = _IEFrameGetCollection ($oIE)
$iNumFrames = @extended For$i = 0 to ($iNumFrames - 1)$sFrameSrc = _IEFrameGetCollection ($oIE,$i).src
MsgBox(0, "Frame Info", $sFrameSrc) Next However, this did not even pass the syntax checker: >Running AU3Check (1.54.1.1) params: from:C:\Program Files\AutoIt3\beta J:\autoit\src\IETests.au3(65,50) : ERROR: syntax error$sFrameSrc = _IEFrameGetCollection ($oIE,$i).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^

So i modified it to work:

$oFrames = _IEFrameGetCollection ($oIE)
$iNumFrames = @extended For$i = 0 to ($iNumFrames - 1)$sFrameSrca = _IEFrameGetCollection ($oIE,$i)
$sFrameSrc =$sFrameSrca.src
MsgBox(0, "Frame Info", $sFrameSrc) Next But now i get this: >Running:(3.1.1.125):C:\Program Files\AutoIt3\beta\autoit3.exe "J:\autoit\src\IETests.au3" J:\autoit\src\IETests.au3 (66) : ==> The requested action with this object has failed.:$sFrameSrc = $sFrameSrca.src$sFrameSrc = $sFrameSrca.src^ ERROR In fact, most of the time when i try to use a dot-anything (.<anything>, such as .src, .name, .value, etc) on an object variable, it fails. Usually with the same error as that above: "The requested action with this object has failed." Can someoen point me in the right direction? I have to imagine these are not normal problems - almost every function from IE.au3 i've tried has failed so far! Also, i'm running WinXP SP2 and IE 6.0.2900.2180.xpsp_sp2_gdr.050301-1519 (what a wonderful version number!) Thanks in advance!

The only one of my tests that fail is FrameSetTest_Error(), which is trying to do _IEFrameGetObjByName on a frame that i know does not exist. Seems like it should throw a NoMatch error instead of dying though I have a question though: I have a site with multiple levels of frames, and i want to drill down to a specific frame (in order to click a link in that frame). I can get the first frame, but all frames below that fail with this error: >Running:(3.1.1.123):C:\Program Files\AutoIt3\beta\autoit3.exe "J:\autoit\src\IETests.au3" J:\autoit\lib\IE.au3 (748) : ==> The requested action with this object has failed.:$o_col = $o_object.document.parentwindow.frames ($s_Name)
$o_col =$o_object.document^ ERROR

If i use _IEGetObjByName() instead of _IEFrameGetObjByName(), i don't get the script failure, however i just get NoMatch errors after the first frame. The code looks like this:

$oFrame = _IEFrameGetObjByName ($oIE, "_sweclient")
$oFrame1 = _IEFrameGetObjByName ($oFrame, "_swecontent")

and...

;Attempt to get the object directly with IEGetObjByName
$oFrame = _IEGetObjByName($oIE, "_sweclient")

;Attempt to get the next one
$oFrame1 = _IEGetObjByName ($oFrame, "_swecontent")

Is there some other object i need to get in the middle? the Frameset maybe?

Thanks!

Thanks. After some testing it is clear that _IEFrameGetObjByName needs to work.

For one thing, I have it set up to handle a situation where there are more than one frame of the same name... testing shows that the DOM access blows up if there are more than one frame or iframe of the same name, so it is unnecessary to allow for this and I'll simplify the routine accordingly.

I'll also trap the error associated with referencing a non-existant name. Thanks for reporting this.

Watch for it in the next release.

Also note that you can avoid the aborting of your script by using _IEErrorHandlerRegister() This will instantiate a COM error handler to that COM errors do not abort your script, will display a console message when an error occurs and will return an @error status of $_IEStatus_ComError. Dale Update: I know I didn't answer your final questions yet -- I'll come back to it as I have not really digested the question yet.

I would expect this to wordk:

$oFrame = _IEFrameGetObjByName ($oIE, "_sweclient")
$oFrame1 = _IEFrameGetObjByName ($oFrame, "_swecontent")

Try examining the HTML in the first frame to insure it includes the nested frame you are after:

$oFrame = _IEFrameGetObjByName ($oIE, "_sweclient")
ConsoleWrite(_IEBodyReadHTML($oFrame) & @CR) Dale No, that fails too. _IEBodyReadHTML will not work on$oFrame

In fact, "$oFrame.body" throws an "variable must be type Object" error. However, IsObj() is true on$oFrame, and ObjName() is "DispHTMLWindow2"

No, that fails too. _IEBodyReadHTML will not work on $oFrame In fact, "$oFrame.body" throws an "variable must be type Object" error.

However, IsObj() is true on $oFrame, and ObjName() is "DispHTMLWindow2" _IEBodyReadHTML returns$o_object.document.body.innerHTML so if there is a document instantiated in that frame it should work.

Try turning on the error handler to see if you might be gettin an Access is denied error:

_IEErrorHandlerEnable()

However, if i enable my own COM error handler (via _IEErrorHanderRegister()), the error description is: "Access is denied." This sounds a lot like$_IEStatus_AccessDenied to me, though it never actually throws that error.

What does this mean? (sorry about being ignorent). I see your mention in the code about cross-site scripting security? What exactly is happening here? The frame points to different site than the parent frame?

Thanks for your help! It's greatly appreciated!

It's greatly appreciated! Quasar Sorry, sad when I can't remember my own code. It is of course _IEErrorHandlerRegister() Where I trap for the Access is Denied error I return the$_IEStatus_AccessDenied status. This is obviously a place I am not looking for that. My goal has been to trap the most common occurances of COM errors and try to give more guidance... this may be another place I can do that... I'll look into it.

Yes, the Access Is Denied error is triggered when the parent and child are from different sites. It is imposed by the DOM to prevent impersonation. Although it would be fine to allow this access in a desktop application like this, on the Internet it is a dangerous thing and we therefore have to live with the restriction as well.

The only suggestion that I have for you would be to display the frame contents in a new window instead of trying to manipulate it in the frame. So long as what is in the frame does not rely on communications with other frames (which presumably it could not due to the same restrictions) then it should work fine.
