IE Error Handling

4 posts in this topic

I am trying to catch an error involving IE.au3 to keep autoIt.exe from exiting.

If I try to navigate to a webpage that I know doesn't exist I alway get

AutoIt Error Line 267 in IE.au3

$o_object.navigate($s_Url)

$o_object.navigate($s_Url)^Error

Error: The requested action with this object has failed.

Is there a way to catch this error and prevent the script from exiting?

I saw things like _IEErrorHandlerRegister and _IEErrorNotify in the help file, but I don't understand how they are used and If they even do what I want.

You didn't show code that causes the error. Post the shortest code snippet you can that generates that error.

But, in general, just putting _IEErrorHandlerRegister() near the top should prevent the error from being fatal, and show useful info in the SciTE console when errors occur.

When I run this, with an obviously bad URL, it doesn't crash:

#include <IE.au3>

$s_Url = "about:blank"
$oIE = _IECreate($s_Url)

$s_Url = "wwww.ggoooggllee.ccoomm"
_IENavigate($oIE, $s_Url)

:)

Thanks, adding _IEErrorHandlerRegister() fixed the problem.

The code that caused it to crash was

_IECreate("BadlyFormatedURL", 0, 1, 0)

I don't expect taht to cause the script to fail no matter how badly the URL is formatted. I tried _IECreate("BadlyFormatedURL", 0, 1, 0) and did not see what you reported. Can you supply a reproducer as well as the console output from _IE_VersionInfo() ??

thanks,

Dale
