ADO访问access做数据库搜索却总是报错,请指教

数据库初始化和连接没有问题 但是总是报：Unhandled exception in ADO.exe(KERNEL.DLL):OxE06D7363:Microsoft C++ Exception错误
void CADODlg::OnReadaccess()
{
// TODO: Add your control notification handler code here

_variant_t var;
CString strName,strAge;

// 清空列表框・
m_AccessList.ResetContent();
strName=strAge="";

try
{
if(!m_pRecordset->BOF)
m_pRecordset->MoveFirst();
else
{
AfxMessageBox("表内数据为空");
return;
}

// 读字段到列表框
while(!m_pRecordset->adoEOF)
{
var = m_pRecordset->GetCollect("Name");
if(var.vt != VT_NULL)
strName = (LPCSTR)_bstr_t(var);
var = m_pRecordset->GetCollect("Age");
if(var.vt != VT_NULL)
strAge = (LPCSTR)_bstr_t(var);

m_AccessList.AddString( strName + " --> "+strAge );

m_pRecordset->MoveNext();
}

m_AccessList.SetCurSel(0);
}
catch(_com_error *e)
{
AfxMessageBox(e->ErrorMessage());
}
}

请使用Coinstallize()初始化ADO，卸载使用UnCoinstallize();
