Hello, I am having error handling issues that is in regards to the NonCopyable Interface library. Here is the source code: #include <boost/noncopyable.hpp> #include <iostream> class A : public boost::noncopyable { public: A() { std::cout << "In A \n" << std::endl; } class AnError {}; void Func() { if () //error condition throw AnError(); } }; int main() { try { A object1; A object2(object1); object1 = object2; } catch (A::AnError) { //tell user about error. } return 0; } } So far, I have tried on the forums in CPlusPlus.com and MSDN, but no responses. Since that Boost.org has created and authored the NonCopyable.hpp library, I would like to get some assistance. Can anybody give me some solutions on how to suppress any compilation errors? Thanks in advance. Email me back at the Cc: if you have any answers or comments with detailed information and examples. John P.
