• Visual C++ On adjacent ">"s in a parameterized declaration

  Hello, There is a syntax erron in the following code -- adjacent ">"s need a delimiter (it is marked AAAA) template <class T> class A {}; template <class T> class B {}; int main() { A<B<int>>(); // AAAA } But VC8 can compile it.

• Visual C++ circular reference in parent/child classes

  I have been trying to understand some code that another guy wrote, and though his code compiles and runs, it seems like it should never have compiled. He has 2 classes. One class is basically the parent, and it includes a pointer to the child it creates. As the child is being created, the parent passes the constructor a "this" pointer, so the child can later access variables in the parent. When I try to duplicate this logic, ...Show All

• Visual C++ Class Designer not a feature for C++?

• .NET Development XSD + XPATH = XSD-Type?

  I got an XSD containing a definition for XML and I got XPath Queries which would return nodes from an XML valid against that XSD.
