_IEFormSubmit() not reconizing error.

**recognizing..

I am using a proxy to submit a form. IE gives me this page:

The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
--------------------------------------------------------------------------------
Please try the following:
Click the Refresh button, or try again later.
If you typed the page address in the Address bar, make sure that it is spelled correctly.
To check your connection settings, click the Tools menu, and then click Internet Options. On the Connections tab, click Settings. The settings should match those provided by your local area network (LAN) administrator or Internet service provider (ISP).
See if your Internet connection settings are being detected. You can set Microsoft Windows to examine your network and automatically discover network connection settings (if your network administrator has enabled this setting).
Click the Tools menu, and then click Internet Options.
On the Connections tab, click LAN Settings.
Select Automatically detect settings, and then click OK.
Some sites require 128-bit connection security. Click the Help menu and then click About Internet Explorer to determine what strength security you have installed.
If you are trying to reach a secure site, make sure your Security settings can support it. Click the Tools menu, and then click Internet Options. On the Advanced tab, scroll to the Security section and check settings for SSL 2.0, SSL 3.0, TLS 1.0, PCT 1.0.
Click the Back button to try another link.
Cannot find server or DNS Error
Internet Explorer

The function returns with a timeout error, but the IE stops doing anything after 3-4 seconds. I am unaware if other functions in IE.au3 do this as well.

_IENavigate and _IELoadWait functions both handle the error correctly.

_IEFormSubmit ($o_Form, 0)
_IELoadWait($o_IE)oÝ÷ Øªè

UPDATE: _IELoadWait will return once the page gets the error, but it returns with @Error set to 0 (meaning no error occured) the _IELoadWait function is not picking up that an error occured, when it did.

_IELoadWait does not know whether what you expected to happen on a page load was what happened or not... it simply waits for the browser to report that the page load operation is COMPLETE (readyState = 4). As far as it is concerned, a message that page cannot be displayed is just as valid as your family vacation photos. _IENavigate behaves the same way...

$o_IE is exactly the same as $o_Form.document.parentWindow

You don't show how $o_IE was established, but if it was created with _IECreate, for example, it is NOT the same as $o_Form.document.parentwindow. If you use ObjName you'll see that $o_IE is a browser object and the other is a window object - they can be used interchangably in many functions, but not all.

There is a challenge with _IEFormSubmit that has been discussed before. The trouble is that you pass a form object to _IEFormSubmit and from that we can get the document and the parent window, but security restrictions prevent us from determining the browser object from there. This can sometimes get us into a cross-site scripting security error that is not something we can recover from... I try to trap for that, but I have recently discovered that the test I am doing for it is too specific and the "Access is denied" error has more than one error number (I test for 169). I'll be releasing a new version soo that should be able to detect this.

So, the workaround that you show is valid, but may not always insure that everything is loaded properly... there is nothing better that can be done baswed on my current understanding because of the cross-site issues I mentioned above.

To verify if you are experiencing this Access Is Denied issue, you can define the undocumented variable $__IEAU3Debug = True and _IELoadWait will spit out information on COM errors it is trapping.

Thanks for the explanation.

I put the debug variable to true but nothing is written to console about any errors from IEloadwait. Here is the complete script thus far.

Hmmm... then I don't understand what problem you are having. Can you summarize what is going wrong in your view again please?

When using a bad connection proxy I get the page

"The page cannot be displayed

The page you are looking for is currently unavailable"

When I submit the form using _IEFormSubmit ($o_Form) it will just sit at the "page cannot be displayed" screen until it times out (long time).

When I attempt to use _IEFormSubmit ($o_Form, 0) with a following _IELoadWait it will say return at the site of "page cannot be displayed" but it will return 0. _IELoadWait does not recognize the error that the page did not correctly load.

Here is the lastest IE events after the requested page was not found:
