Accessing Autosearch Internet Option from a BHO

[Ramus Nee]

IE Internet Options include a "Search from the address bar" knob, in the
Advanced category. Users can turn autosearch on or off using that knob (among
other things).

How can my C++ application (an IE BHO) determine whether autosearch is
enalbed? I do not see any relevant flag in the InternetQueryOption call. Are
there some Registry variable that my application should look at?

Thank you.

P.S. I am reposting this question after tweaking account options to help

Hi,

Thanks for posting at the newsgroup!

So far as I know, if the registry key "DefaultSearchUrl" exists under the
location:
HKEY_CURRENT_USER\Software\Microsoft\Search Assistant Value Name\

For example, if the key "DefaultSearchUrl" exists under the location above
with the value http://www.google.com/search?q=, then IE will use Google as
the default addressbar search engine. So I'd suggest you can have a
checking on this value whether IE has enabled the autosearch in address
bar.

Besides, the configuration information used by IE regarding search is
stored in the registry. For your development, I'd also suggest you can use
the Regmon registry monitor utility from Sysinternals.com to observe what
key IE has used for the search.

Please feel free to let me know if you have any further question on this
issue.

Have a nice day!
