Remove this one

The last parameter should be void** (two stars, not one). I've
copied'n'pasted your method signature and did not notice this error,
sorry.

*ppvObject = 0;

*ppvObject = static_cast<IMoniker*>(this);

Add pUrlMoniker->AddRef(), or alternatively set m_refCount to 1 in
CHTMLMoniker's constructor.

Remove this already. You do _not_ need a standard URL moniker. You
should _not_ call CreateURLMoniker. You overwrite your pUrlMoniker
variable that points to an instance of CHTMLMoniker class, with a
pointer to completely unrelated object.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
