Hi,all experts.
I have a dialog with some buttons.I want the tooltip of the buttons can still appear until mouse moves out.So I want to write the code like this:
      ::SendMessage(m_hWnd, TTM_SETDELAYTIME,TTDT_AUTOPOP, MAKELPARAM(30000, 0));
But how can I get m_hWnd of the tooltip window?

Hi wang_gh,

you can try following:

handle the TTN_SHOW notification like this:

// in h file
class CMyDialog : public CDialog
{
 ...
 afx_msg void OnShowToolTip( UINT id, NMHDR* pNotifyStruct, LRESULT* result );
 ...
};

// in cpp file
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
....
 ON_NOTIFY_EX_RANGE( TTN_SHOW, 0, 0xFFFF, OnShowToolTip )
....
END_MESSAGE_MAP()
void
CMyDialog::OnShowToolTip( UINT id, NMHDR* pNotifyStruct, LRESULT* result )
{
 ::SendMessage( pNotifyStruct->hwndFrom, TTM_SETDELAYTIME, ... );
}

hope that helps,

ZOPPO
