请教WM_NOTIFY问题
看下面一段程序代码
BOOL CTestDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
.
.
this->SendMessage(WM_NOTIFY,m_psttt.hdr.idFrom,(LPARAM)&m_psttt);
return CDialog::OnSetCursor(pWnd, nHitTest, message);
}
BOOL CTestDlg::OnTipNotify( UINT id, NMHDR *pNMHDR, LRESULT * pResult )
{
return(FALSE);
}
为什么this->SendMessage(WM_NOTIFY,m_psttt.hdr.idFrom,(LPARAM)&m_psttt);
无效,根本不运行OnTipNotify(),为什么?
请教各位大虾
