vc++连接access数据库问题

1.在StdAfx.h中写了：
#import "C:\Program Files\Common Files\System\ado\msado15.dll" rename_namespace rename("EOF","adoEOF")
2.在Dlg.cpp中添加了一个按钮，来显示数据库中的信息代码如下：
void CStudentDlg::OnBtnAdd()
{
AfxOleInit();
m_pConnection.CreateInstance(__uuidof(Connection));
// 在ADO操作中建议语句中要常用try...catch()来捕获错误信息，
// 因为它有时会经常出现一些意想不到的错误。jingzhou xu
try
{
// 打开本地Access库Info.mdb
m_pConnection->Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=db1.mdb","","",adModeUnknown);
}
catch(_com_error e)
{
AfxMessageBox("数据库连接失败，确认数据库Demo.mdb是否在当前路径下!");
// return FALSE;
}

_RecordsetPtr pHandlerRecordset;
pHandlerRecordset.CreateInstance(__uuidof(Recordset));
try
{
pHandlerRecordset->Open("SELECT * FROM Name", // 查询InfoTable表中所有字段
m_pConnection.GetInterfacePtr(), // 获取库接库的IDispatch指针
adOpenDynamic,
adLockOptimistic,
adCmdText);
}
catch(_com_error *e)
{
AfxMessageBox(e->ErrorMessage());
}

_variant_t var;
CString strName;
while(!pHandlerRecordset->adoEOF)
{
var = pHandlerRecordset->GetCollect("Name");
if(var.vt != VT_NULL)
strName = (LPCSTR)_bstr_t(var);
m_List_Result.AddString(strName);
pHandlerRecordset->MoveNext();
}
pHandlerRecordset->Close();
pHandlerRecordset.Release();
pHandlerRecordset = NULL;
MessageBox("数据已连接！","提示");
}
但是编译一直有问题：

执行 cl.exe 时出错.

stu1.exe - 1 error(s), 0 warning(s)

如果把impor语句改成：#import "C:\Program Files\Common Files\System\ado\msado15.dll" rename_namespace \rename("EOF","adoEOF")
又出现如下错误：

有没有人有过同样的经历啊，这是怎么回事，要怎样才能解决啊？有没有人可以指点一下。着急。。。。。
