The IReadCookie::get_Item method retrieves the specified item from a cookie object.
HRESULT get_Item(
VARIANT Var, // contains the name of the item in the collection
VARIANT * pVariantReturn
// pointer to a VARIANT that receives the item value
);
If Var is a string, the cookie is assumed to be a dictionary cookie, and Var is treated as the key. If Var is a variant with type VT_ERROR and error code DISP_E_PARAMNOTFOUND, then the cookie is assumed to be a simple cookie and the primary value is returned. (If the cookie is a dictionary, the sequence of key/value pairs are URL-encoded and returned.)
If a dictionary lookup is performed and the item is not found, then pVariantReturn returns VT_EMPTY. Otherwise a VT_BSTR is always returned.
