The code listing has the destructor for Biz public. The compiler will complain: error C2035: a non-virtual destructor with 'public' accessibility is not allowed for this type
1> a non-virtual destructor must have 'protected private' or 'private' accessibility

Fix: change "public: ~Biz(){}" to "private: ~Biz(){}"

Also, warning C4419: 'BindableAttribute' has no effect when applied to private ref class 'MyFirstApp::Person'. Consider making 'MyFirstApp::Person' public instead The effect of this is NO text on the screen when you run the application.

Fix: change "ref class Biz sealed" to "public ref class Biz sealed" and "ref class Person sealed" to "public ref class Person sealed"

Note from the Author or Editor:
The suggested fix is ok, thanks.

Implementation of the code as written in book will result in no search results found. The sample code does work, however. The difference is that the book never states that in the method:

void SearchPeople::Filter_SelectionChanged(Object^ sender, SelectionChangedEventArgs^ e)

You need to change 2 instances of IVector<Object^>^ to IVector<Person^>^.

Note from the Author or Editor:
Between step 2 and step 3, in the code of Filter_SelectionChanged you have to replace IVector<Object^>^ with IVector<Person^>^ .
