This introductory program illustrates the use of the CRunTime class:

#include <afxwin.h>

class myframe :public CFrameWnd
{
public:
	myframe()
	{
		Create(0,"james");
	}
	void Display()
	{
		CRuntimeClass *ptr;
		ptr=RUNTIME_CLASS(CFrameWnd);
		CString Res;
		Res.Format("%s",ptr->m_lpszClassName);
		AfxMessageBox(Res,MB_OK);

	}
};
class myapp:public CWinApp
{
public:
	int InitInstance()
	{
		myframe *p=new myframe;
		p->ShowWindow(3);
		p->Display();
		m_pMainWnd=p;
	return 1;
	}
};

myapp a;
