void CDlg::OnKeydownListFile(NMHDR* pNMHDR, LRESULT* pResult)<br /> {<br /> LV_KEYDOWN* pLVKeyDow = (LV_KEYDOWN*)pNMHDR;<br /> // TODO: Add your control notification handler code here<br /> int i=0;<br /> int n = 0;<br /> int to_delete[65535];</p> <p> if (pLVKeyDow->wVKey == VK_DELETE)<br /> {<br /> POSITION pos = m_list.GetFirstSelectedItemPosition();<br /> if(pos==NULL)<br /> {<br /> TRACE0("No items were selected!/n");<br /> }<br /> else<br /> {<br /> while(pos)<br /> {<br /> to_delete[i++] = m_list.GetNextSelectedItem(pos);<br /> }<br /> }<br /> n=m_list.GetSelectedCount();//被选择总数；<br /> int k = 0;<br /> for(i = 0; i < n; i++)<br /> {<br /> m_list.DeleteItem(to_delete[i]-k);//依依删除；<br /> k++;<br /> }<br /> }<br /> *pResult = 0;<br /> }
