15. (If you are using MSVC 5 or 6, first close both the menu and the icon windows. You

    DocView.rc file and click OK.


16. Add a new header file named Exercise and, in it, create the necessary classes as
    follows:

#include <afxext.h> // For CEditView

#include "resource.h"

class CExerciseApp : public CWinApp

{

BOOL InitInstance();

DECLARE_MESSAGE_MAP()

};

class CMainFrame : public CFrameWnd

{

DECLARE_DYNCREATE(CMainFrame)

afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);

DECLARE_MESSAGE_MAP()

};

class CExerciseDoc : public CDocument

{

DECLARE_DYNCREATE(CExerciseDoc)

DECLARE_MESSAGE_MAP()

};

class CExerciseView : public CEditView

{

DECLARE_DYNCREATE(CExerciseView)

DECLARE_MESSAGE_MAP()

};

17. Add a new source file named Exercise and, in it, implement the classes as follows:

#include <afxwin.h>

#include "Exercise.h"

BEGIN_MESSAGE_MAP(CExerciseApp, CWinApp)

END_MESSAGE_MAP()

BOOL CExerciseApp::InitInstance()

{

CSingleDocTemplate* pDocTemplate;

pDocTemplate = new CSingleDocTemplate(

IDR_MAINFRAME,
