MFC ComboBox 和 Edit

初始化：

void CaftdemoDlg::InitComb()
{
    CString classifty[] = {"大于","大于等于","等于","小于","小于等于","不等于"};
    int HideInt[6] = {1,5,4,2,6,8};

    for (int i = 0;i < 6; ++i)
    {
        int iAddString = m_showClassify.AddString(classifty[i]);
        m_showClassify.SetItemData(iAddString ,HideInt[i]);
    }
}

调用：

void CaftdemoDlg::OnBnClickedBtncal()
{
    CString strGetAge,strGetClassify;

    m_showAge.GetWindowTextA(strGetAge);

    int getCurSel = m_showClassify.GetItemData(m_showClassify.GetCurSel());
    if(getCurSel&8)
    {
        strGetClassify += "!=";
    }
    else
    {
        if(getCurSel & 1)
        {
            strGetClassify += ">";
        }
        else if(getCurSel & 2)
        {
            strGetClassify += "<";
        }

        if(getCurSel & 4)
        {
            strGetClassify += "=";
        }
    }

    MessageBox(strGetClassify + strGetAge,_T("程序运行结果"),MB_OK);
}
