Those are separate applications with their own top-leve windows; you cannot host them. You can only host controls. In the case of Office applications like Word, you can host the Active Document container (pretty much everything) and - if you go to a massive amount of work - even get information to host the toolbars. This is not supported in .NET, however, not until 2.0 at least (which adds the ActiveDocument control. You can write your own, though, but you must have a good understanding of COM and interoperability with .NET; otherwise, you should try googling the net for examples that already do this. Also note that you can host the Word OCW control which was designed to be hosted in a web page (OCW == "Office Components for the Web"). That's as easy as customizing your Toolbox in Visual Studio and dragging "Word" onto your form. Now you can host Word documents. You do the same with Windows Media Player as someone else suggested. Note all applications support this, however: only ActiveX controls are supported. This posting is provided "AS IS" with no warranties, and confers no rights.
