Update an href on an IHTMLLinkElement

Question

I need to update the contents of an href on an IHTMLLinkElement. What I've come up compiles but causes an error as soon as it's execute

static const CComBSTR href(L"http://www.google.com");
spLinkElement->put_href(href); // IHTMLLinkElement

The error I get is
