I am developing a 'outlook style' menu system which basically has a main menu bar, tool bar, navigation panel on the left side of the form and a mdi container consuming the rest of the form.  When the user clicks on one of the navigation buttons I want to launch the associated program within the mdi container.(I'm not committed to the mdi container, it's just something I was experimenting with and seemed to work okay). I have it working fine with forms within the actual menu assembly but I need to launch external applications, which could be VB6 or VB.NET exe's or .NET DLL's. 

I have experimented with 'Process.Start', which works fine, however it opens up the application in a new window. I really want to run the applications within a panel in the menu application, similar to the outlook inbox etc... I assume it's possible.

I'm open to any suggestions as I am still in the experimental stage. Any help would be appreciated.

Thanks,

Tim Dol
