.NET Forum / .NET Framework / New Users / August 2005a few MC++ / (Plain C++ really) questions about constructor & exception
- 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?  SignatureThere are 10 kinds of people in this world. Those who understand binary and those who don't. >- if I use the default new operator, are all the instance variable >initialize to NULL / 0 ?

I suggest that you post again in microsoft.public.dotnet.languages.vc Regards, Will "William DePalo [MVP VC++]" <willd.no.spam@mvps.org> wrote in message news:% > I suggest that you post again in > > microsoft.public.dotnet.languages.vc 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... > 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. Regards, Will so true ;-) SignatureThere are 10 kinds of people in this world.
