1) i have a windows form based (CLR , visual studio 2005 )
application , which is running fine.
2) i have two more application in MFC ( VC++, visual studio 2005 ),
which are running fine.

Now i need to make a combined application which will kind of contain
all three. Basically the idea is to have 3 tabs and each tab showing a
different application.

This means i have to either port windows form based application to VC+
+ or VC++ applications to .NET form based.

Is there an easy way out. I don't want to rewrite and test old
codes...
