<br>内容：是CListBox还是CList？<BR>好像都没有addstream成员函数！！！<BR><BR>如果是CListBox，清空<BR>使用m_list.ResetContent();<BR>如果是CLIst，清空<BR>使用m_list.RemoveAll();<BR><BR>对于CListBox，取出字符串<BR>使用GetText成员函数即可。<BR>对于CList那就要看你怎样设置的了。

<br>内容：举个例子(其中m_pInfo为ListCtrl)：<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_pInfo.InsertColumn(0, "test1", LVCFMT_LEFT,140);<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_pInfo.InsertColumn(1, "test2", LVCFMT_LEFT,250);<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_pInfo.InsertColumn(2, "test3", LVCFMT_LEFT,250);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;ListView_SetExtendedListViewStyleEx(m_pInfo.m_hWnd,<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;LVS_EX_FULLROWSELECT|LVS_EX_GRIDLINES|LVS_EX_INFOTIP,<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;LVS_EX_FULLROWSELECT|LVS_EX_GRIDLINES|LVS_EX_INFOTIP);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;m_pInfo.InsertItem(0, "0123456789");<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;m_pInfo.InsertItem(1,"9876543210");<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;m_pInfo.InsertItem(2, "ttttttttttt");<BR>

<br>内容：你说的整行选取带网格的报告视。<BR><BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//判断列表视中是否有行被选中<BR>&nbsp;&nbsp;&nbsp;&nbsp; if(m_pInfo.GetNextItem(-1,LVNI_SELECTED)==-1)<BR>&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;this-&gt;MessageBox("没有选中记录","提示",MB_OK|MB_ICONINFORMATION);<BR>&nbsp;&nbsp; }<BR>&nbsp;&nbsp; else<BR>&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;int nRowSelected=m_pInfo.GetNextItem(-1,LVNI_SELECTED);//获取被选中的行号<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString strPersonNumber=m_pInfo.GetItemText(nRowSelected,0);//取出选中行的第一个字段内容<BR>&nbsp;&nbsp;&nbsp;&nbsp;}
