Due to a conformance change in the C++ compiler, code change may be required before your project will build without errors.  Previous versions of the C++ compiler allowed specification of member function pointers by member function name (e.g. MemberFunctionName).  The C++ standard requires a fully qualified name with the use of the address-of operator (e.g. ClassName::MemberFunctionName).  If your project contains forms or controls used in the Windows Forms Designer, you may have to change code in InitializeComponent because the designer generated code used the non-conformant syntax in delegate construction (used in event handlers).
