Practical learning: Displaying a Modal Dialog Box

1. To display the dialog box as modal, in the InitInstance() event of your CWinApp
   derived class, call the DoModal() method using your dialog variable:

#include <afxwin.h>

#include <afxdlgs.h>

#include "resource.h"

class CExerciseApp : public CWinApp

{

public:

BOOL InitInstance();

};

class CExerciseDlg : public CDialog

{

public:

enum { IDD = IDD_EXERCISE_DLG };

CExerciseDlg();

~CExerciseDlg();

};

CExerciseDlg::CExerciseDlg()

: CDialog(CExerciseDlg::IDD)

{

}

CExerciseDlg::~CExerciseDlg()

{

}

BOOL CExerciseApp::InitInstance()

{

CExerciseDlg Dlg;

m_pMainWnd = &Dlg;

Dlg.DoModal();

return TRUE;

}

CExerciseApp theApp;
