CTestApp, CMainFrame, CTestDoc, CTestView

◎ CTestApp에서
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
CTestDoc* pDoc = (CTestDoc*)((CMainFrame*)AfxGetMainWnd())->GetActiveDocument();
CTestView* pView = (CTestView*)((CMainFrame*)AfxGetMainWnd())->GetActiveView();

◎ CMainFrame에서
CTestApp* pApp = (CTestApp*)AfxGetApp();
CTestDoc* pDoc = (CTestDoc*)GetActiveDocument();
CTestView* pView = (CTestView*)GetActiveView();

◎ CTestDoc에서
CTestApp* pApp = (CTestApp*)AfxGetApp();
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
CTestView* pView = (CTestView*)((CMainFrame*)AfxGetMainWnd())->GetActiveView();

◎ CTestView에서
CTestApp* pApp = (CTestApp*)AfxGetApp();
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
or (CMainFrame*)GetParent();
CTestDoc* pDoc = (CTestDoc*)((CMainFrame*)AfxGetMainWnd())->GetActiveDocument();
or (CTestDoc*)GetDocument();
