cout << "pMyDoc->IsKindOf(RUNTIME_CLASS(CDocument)) " << pMyDoc->IsKindOf(RUNTIME_CLASS(CDocument)) << "\n";
cout << "pMyDoc->IsKindOf(RUNTIME_CLASS(CCmdTarget)) " << pMyDoc->IsKindOf(RUNTIME_CLASS(CCmdTarget)) << "\n";
cout << "pMyDoc->IsKindOf(RUNTIME_CLASS(CObject)) " << pMyDoc->IsKindOf(RUNTIME_CLASS(CObject)) << "\n";
cout << "pMyDoc->IsKindOf(RUNTIME_CLASS(CWinApp)) " << pMyDoc->IsKindOf(RUNTIME_CLASS(CWinApp)) << "\n";
cout << "pMyDoc->IsKindOf(RUNTIME_CLASS(CView)) " << pMyDoc->IsKindOf(RUNTIME_CLASS(CView)) << "\n";

cout << "pMyView->IsKindOf(RUNTIME_CLASS(CView)) " << pMyView->IsKindOf(RUNTIME_CLASS(CView)) << "\n";
