我用的ADO对象编程访问数据库，我想根据number一项查询，但用标示的循环只能查询前两个，为什么？？？
谢谢

void CAdoDll::OnSearch()
{
    // TODO: Add your control notification handler code here
    UpdateData(TRUE);
    int curSel=m_list.GetCurSel();
    _variant_t va;
    if(curSel<0)  return;
    m_pRecordset->MoveFirst();
    m_pRecordset->Move(long(curSel));
    va=m_pRecordset->GetCollect("number");
    try
    {
        
        if(m_no!=(LPCSTR)_bstr_t(va))
        {
          m_pRecordset->MoveNext();
          m_pRecordset->Move(long(curSel));
        va=m_pRecordset->GetCollect("number");
        }
        if(va.vt!=VT_NULL)
            m_no=(LPCSTR)_bstr_t(va);
        va=m_pRecordset->GetCollect("name");
        if(va.vt!=VT_NULL)
            m_name=(LPCSTR)_bstr_t(va);
         va=m_pRecordset->GetCollect("department");
        if(va.vt!=VT_NULL)
            m_bumen=(LPCSTR)_bstr_t(va);
         va=m_pRecordset->GetCollect("salary");//m_gongzi
        //va.ChangeType(VT_I4,NULL); //V_I4 对应long型
        //m_gongzi=V_I4(&va);
        m_gongzi=(short)(va);
        UpdateData(false);
        
    }
    catch(_com_error *  e)
    {AfxMessageBox(e->ErrorMessage());}
   
}
