Chapter 18: Progress-Based Controls Visual C++ and MFC Fundamentals

To dynamically create a scroll bar control, declare a pointer to CScrollBar using the the

new operator and call its Create() method to initialize it. Here is an example:

class CScrollingDlg : public CDialog

{

// Construction

public:

CScrollingDlg(CWnd* pParent = NULL); // standard constructor

virtual ~CScrollingDlg();

...

// Implementation

protected:

// Generated message map functions

//{{AFX_MSG(CScrollingDlg)

virtual BOOL OnInitDialog();

//}}AFX_MSG

DECLARE_MESSAGE_MAP()

private:

CScrollBar *Scroller;

};

...

// ScrollingDlg.cpp : implementation file

//

#include "stdafx.h"

#include "Frame3.h"

#include "ScrollingDlg.h"

#ifdef _DEBUG

#define new DEBUG_NEW

#undef THIS_FILE

static char THIS_FILE[] = __FILE__;

#endif
