用ADO如何从SQL上读取的数据显示到EDIT控件上

代码如下：
_ConnectionPtr m_pConnection;
_RecordsetPtr m_pRecordset;
_CommandPtr m_pCommand;
m_pConnection.CreateInstance(__uuidof(Connection)); 
m_pRecordset.CreateInstance(__uuidof(Recordset));
m_pCommand.CreateInstance(__uuidof(Command));
m_pConnection->ConnectionTimeout = 5;
HRESULT hr;
hr = m_pConnection->Open("driver={SQL Server};Server=.\\sqlexpress;DATABASE=qwe;UID=sa;PWD=123","","",adModeUnknown);
_variant_t RecordsAffected;
m_pRecordset->Open("SELECT * FROM users",_variant_t((IDispatch *)m_pConnection,true),adOpenStatic,adLockOptimistic,adCmdText);

然后该写什么？
我是菜鸟。

str= m_pRecordset->GetCollect("字段名").bstrVal;
这个str是edit控件关联的变量，然后调用UpdateData(false);
