virtual HRESULT OnGetOptionKeyPath( 
   LPOLESTR* pchKey, 
   DWORD dwReserved  
);

Parameters

  • pchKey
    Address of an LPOLESTR that receives the registry subkey string where the host stores its default options. This subkey will be under the HKEY_CURRENT_USER key. Allocate this memory using CoTaskMemAlloc. The calling application is responsible for freeing this memory using CoTaskMemFree. This parameter should always be initialized to NULL, even if the method fails.

Return Value

S_OK if successful, or S_FALSE otherwise. If S_FALSE, Internet Explorer or MSHTML will default to its own user options.
