How to judge if tabbed browsing is enabled in IE using VB?

I'm doing an automation job with InternetEx开发者_JS百科plorer object.

Only way I can think of doing this is by checking the registry settings for Internet Explorer.

The registry setting (on Win7 IE8) is under HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TabbedBrowsing\Enabled.
