This message box delays its dismissal by disabling the OK button for a delay interval. It also has an optional auto-close feature. There are two versions, one uses a WH_CBT hook and some basic window tricks like sub-classing to achieve its goal. The other one is more MFC-ied.
// DelayMsgBoxDemoDlg.h : header file
//

#pragma once


// CDelayMsgBoxDemoDlg dialog
class CDelayMsgBoxDemoDlg : public CDialog
{
// Construction
public:
	CDelayMsgBoxDemoDlg(CWnd* pParent = NULL);	// standard constructor

// Dialog Data
	enum { IDD = IDD_DELAYMSGBOXDEMO_DIALOG };

	protected:
	virtual void DoDataExchange(CDataExchange* pDX);	// DDX/DDV support


// Implementation
protected:
	HICON m_hIcon;

	// Generated message map functions
	virtual BOOL OnInitDialog();
	afx_msg void OnPaint();
	afx_msg HCURSOR OnQueryDragIcon();
	DECLARE_MESSAGE_MAP()
public:
	afx_msg void OnBnShow();
	CString m_text;
	UINT m_delay;
	BOOL m_close;
	BOOL m_showicon;	
	int m_icon;
	afx_msg void OnBnClickedOk();
};
