My guess it has nothing with MSVC and its MDI interface at all.
The ROOT delete and new NEED the TROOT global object. So try to
introduce it somehow for your code and then try again
#include "TROOT.h"
. . .
TROOT GlobalRoot("RootRoot", "This is to make ROOT happy");
. . .
If you will create a DLL with your example and load it with ROOT
as Pasha Murat offered it will work, since that global TROOT is
supplied by ROOT package itself.
I think this helps (I mean new/delete interruption) to make a next
step but probably you'll stick with a next one namely with the
"Message event loop" supplied by MS Studio. Dont' forget ROOT has its
own Event Loop inside. To manage your (MDI) one, you are required
(very likely) to create a separate thread in your application first.
Anyway if you has spent 8 weeks only (?) probably you should
regard switching to ROOT completely (depends your task of course).
Ones upon a time I was thinking to use MFC but failed (taking in
account cross-platform issue). It was more easy to write everything
ourselves. I say it can be done, the question is whether it worth
(at the moment at least).
