<br>主题：关于Radio Button
<br>内容：我作了一组Radio Button（四个），初始化时，m_Radio1-&gt;SetCheck（TRUE）；我希望当我改选其他几个时，能将我选择的结果保存下来，而不是每次重新运行时又回到初始状态。我该怎么办，请高手帮帮忙，谢谢！

<br>内容：你可以把你所选择的操作状态存到一个文件里去，然后再在初始化时到这文件里去读你操作状态。祝你成功！具体操作如下：<BR>//你的初始化函数：<BR>BOOL CMyDlg::OnInitDialog()<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;CDialog::OnInitDialog();<BR>&nbsp;&nbsp; //TODO: Add extra initialization here<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString str;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CFile fileopen;<BR>&nbsp;&nbsp;&nbsp;&nbsp;if(fileopen.Open("MyProc.dat",CFile::modeRead|CFile::shareExclusive))<BR>&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CArchive aropen(&amp;fileopen,CArchive::load);&nbsp;&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for(;aropen.ReadString(str);)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;m_nOption = atoi(str);//m_nOption是定义的Radio Button的变量<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;aropen.Close();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;fileopen.Close();<BR>&nbsp;&nbsp;&nbsp;&nbsp;}<BR><BR>//你想要保存结果的函数：(我用的是一个BUTTON事件，你随便！）<BR>void CMyDlg::OnButtonMsg() <BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;UpdateData(TRUE);<BR>&nbsp;&nbsp;&nbsp;&nbsp;switch(m_nOption)<BR>&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;case 0:<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; m_result = m_nOption;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;<BR>&nbsp;&nbsp;&nbsp;&nbsp;case 1:<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; m_result = m_nOption;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;<BR>&nbsp;&nbsp;&nbsp;&nbsp;default:<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; m_result = m_nOption;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;<BR>&nbsp;&nbsp;&nbsp;&nbsp;}<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CString temp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CFile filesave("MyProc.dat",CFile::modeCreate|CFile::modeWrite|CFile::shareExclusive);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CArchive arsave(&amp;filesave,CArchive::store);&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; temp.Format("%d",m_nOption);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; arsave.WriteString(temp);&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; arsave.Close();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; filesave.Close();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; UpdateData(FALSE);<BR>}<BR>
