URL Sets or gets the URL for the current document. vlinkColor Sets or gets the color of the links that the user has visited. write Writes one or more HTML expressions to a document in the specified window. writeln Writes one or more HTML expressions, followed by a carriage return, to a document in the specified window.
Remarks
Typically, every window object has a corresponding document object that you can get by calling the QueryInterface method with the IID_IHTMLDocument or IID_IHTMLDocument2 interface identifiers. Windows that contain HTML documents always have valid document objects; windows that contain documents in other formats might not have valid document objects.
In general, before you attempt to get the document object for a window that is not the current window, make sure that the source file associated with that window is an HTML document file or a file that can be represented as an HTML document, for example, a text file.
