HRESULT value = object.get_source(** p);
Property values
Type: Object
the window that sent the message.
Remarks
When pages send cross-document messages with IHTMLWindow6::postMessage, the target window receives a reference to the sender of the message. If the two pages are hosted in the same ___domain, the target window has full access to the Document Object Model (DOM) of the sender. If not, the target can only respond to the message sender with IHTMLWindow6::postMessage; any other interaction will return E_ACCESSDENIED.
