In a program based dialog,KillTimer error!

[HawkOfWinter]

BOOL CTestDlg::OnInitDialog()
{
	//...

	// TODO: Add extra initialization here
	SetTimer(0, 10000, NULL);

	return TRUE;  // return TRUE  unless you set the focus to a control
}

CTestDlg::~CTestDlg()
{
	KillTimer(0); // error here, why?
}

I thought the timerID had to be non-zero value.

[HawkOfWinter]

Even if timerID is 1, err also.

You're passing in different Window Handles to SetTimer and KillTimer, which is a nonsense.

[guestgulkan]

The SetTimer function returns a value. It is this value you should pass to KillTimer function

BOOL CTestDlg::OnInitDialog()
{
	//assume we have a member variable called m_timerID

	// TODO: Add extra initialization here
	m_timerID = SetTimer(1, 10000, NULL);

	return TRUE;  // return TRUE  unless you set the focus to a control
}

CTestDlg::~CTestDlg()
{
	KillTimer(m_timerID); 
}
