a few MC++ / (Plain C++ really) questions about constructor & exception

[Lloyd Dupont]

- if I use the default new operator, are all the instance variable
initialize to NULL / 0 ?
- if there is not enough memory what happend with new ? does it return NULL
or throw an exception?
- if new throw a native C++ exception what happen in Managed C++ ?!
- if there is an exception in a construtor, is ~MyClass() called?
- if I want to throw an exception in a constructor should I free all native
type before? or should I throw and let the destructor (which check nullity
before deleting) do its job?

I suggest that you post again in

That's a good idea!
I didn't though of that as I don't usually do C++ programing....
But in some case, surprisingly, Managed C++ is much leaner...

It really excels when you need to make use of both managed and native
classes in the same module or executable by providing the "it just works"
capability as well as Platform/Invoke available to all the other languages.
