Making Apps MdiChildren

Question

All, I am trying to find a way to make the application instances of Word or IE that I create in my .NET application MdiChildren of the application and cannot find a way to do this. Documentation on the properties and methods of the Word, ExplorerLib libraries is very difficult to find. If anybody has any source of documentation on these objects or ideas about how to make the application windows MdiChildren of my application, I would greatly appreciate it. Thank you.
