VC+ADO操作access数据库问题~~

VC+ADO操作access数据库的问题，我是这样做的，建一个基于对话框的MFC程序，添加两个对话框类CAdoRWAccessDlg（主对话框）和CINSERT，在 CINSERT中通过代码：CAdoRWAccessDlg  dlg;
dlg.InsertDate(m_InName, m_InDate, m_InSWork, m_InOWork, m_InTime1, m_InTime, m_InWork,m_InBeiZhu);调用CAdoRWAccessDlg中的函数CAdoRWAccessDlg::InsertDate(CString InName, COleDateTime InDate, CString InSWork, CString InOWork, CString InTime1, CString InTime, CString InWork,CString InBeiZhu)来添加新的记录，为什么总是不成功？请高手指点下~~~

问题补充：在CAdoRWAccessDlg::InsertDate(CString InName, COleDateTime InDate, CString InSWork, CString InOWork, CString InTime1, CString InTime, CString InWork,CString InBeiZhu)函数中不添加代码没出错，但加入以下代码就出错：
      UpdateData();
try
{
// 写入各字段值
m_pRecordset->AddNew();

m_pRecordset->PutCollect("姓名", _variant_t(m_Name));

m_pRecordset->PutCollect("考勤日期", _variant_t(m_Date));

m_pRecordset->PutCollect("上班时间", _variant_t(m_SWork));

m_pRecordset->PutCollect("下班时间", _variant_t(m_OWork));

m_pRecordset->PutCollect("出勤时间", _variant_t(m_Timer));

m_pRecordset->PutCollect("时间段", _variant_t(m_Timer2));

m_pRecordset->PutCollect("工作内容", _variant_t(m_Work));
