SDI 형태
1.     MainFrame 얻기
-          CMainFrame *pFrame = (CmainFrame *) AfxGetMainWnd();

2.     App 포인터 얻기
-          CTestApp *pApp = (CtestApp *) AfxGetApp();

3.     Document 포인터 얻기
-          CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
    CTestDoc *pDoc = (CTestDoc *)pFrame->GetActiveDocument();
-          CTestDoc *pDoc = ((CMainFrame *)AfxGetMainWnd())->GetActiveDocument();

4.     View 포인터 얻기
-          CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
     CTestView *pView = (CTestView *)pFrame->GetActiveView();
-          CTestView *pView = ((CMainFrame *)AfxGetMainWnd())->GetActiveView();

MDI 형태
1.     ChildFrame 포인터 얻기
-          CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
    CChildFrame *pChild = (CChildFrame *)pFrame->GetActiveFrame();
-          CChildFrame *pChild = ((CMainFrame *)AfxGetMainWnd())->GetActiveFrame();

2.     Document 포인터 얻기
-          CMainFrame *pFrame = (CMainFrame)AfxGetMainWnd();
    CChildFrame *pChild = (CChildFrame *)pFrame->GetActiveFrame();
    CMdiTestDoc *pDoc = (CMdiTestDoc *)pChild->GetActiveDocument();
-          CMdiTestDoc *pDoc = (((CMainFrame *)AfxGetMainWnd())->GetActiveFrame())->GetActiveDocument();

3.     View 포인터 얻기
-          CCainFrame *pFrame = (CMainFrame)AfxGetMainWnd();
    CChildFrame *pChild = (CChildFrame *)pFrame->GetActiveFrame();
    CMdiTestView *pView = (CMdiTestDoc *)pChild->GetActiveView();
-          CMdiTestView *pView = (((CMainFrame *)AfxGetMainWnd())->GetActiveFrame())->GetActiveView();
