but the event not occur WM_TIMER in subclassing

button class.

Why not???

You mean that the class wizard does not add the right code to your source files, or that the WM_TIMER event is not received in your CMyButton OnTimer() function?

[nukbaby]

dear..

Of course, i write..

1. WM_TIMER envet function : On_Timer..

MessageBox("Test Message");

2. WM_CREATE envet function : On_Create;

SetTime(1, 500, NULL );

in subclassing class files.... ( in classWiazrd )

but it's not display messagebox

In Subclassing class, WM_TIMER event ?? occur or not occur.... ??

ps : i'm poor at english sorry...

Your code should look look similar to the following:


//...
// MyButton.h
//...
// CMyButton window

class CMyButton : public CButton
{
// Construction
public:
CMyButton();

// Attributes
public:

// Operations
public:
void StartTimer();
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CMyButton)
//}}AFX_VIRTUAL

// Implementation
public:
virtual ~CMyButton();

// Generated message map functions
protected:
//{{AFX_MSG(CMyButton)
afx_msg void OnTimer(UINT nIDEvent);
//}}AFX_MSG

DECLARE_MESSAGE_MAP()
};



// Mybutton.cpp
//...
#define TIMER_MYTIMER 101
//...
BEGIN_MESSAGE_MAP(CMyButton, CButton)
//{{AFX_MSG_MAP(CMyButton)
ON_WM_TIMER()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CMyButton message handlers

void CMyButton::StartTimer()
{
SetTimer(TIMER_MYTIMER, 1000, NULL);
}

void CMyButton::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
if (nIDEvent == TIMER_MYTIMER)
{
KillTimer(TIMER_MYTIMER);
TRACE("Timer message received in CMyButton\n");
}
else
CButton::OnTimer(nIDEvent);
}





Pay close attention to the message map sections.
