<br>主题：这两个参数怎么用？
<br>内容：void CDlg1::OnClicklist1(NMHDR* pNMHDR, LRESULT* pResult) <BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;// TODO: Add your control notification handler code here<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;//<BR>&nbsp;&nbsp;&nbsp;&nbsp;*pResult = 0;<BR>}<BR>这个函数中的两个参数该如何用？<BR>我想鼠标点击该列表控件的第二列时能弹出一个对话框！
