Remarks

Typically, every window object has a corresponding document object that you can get by calling the QueryIntrerface 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.

This interface may also be referred to in code as IOmDocument2.
