急急！！初始化OLE、COM库环境是报”空错“

Question

总是能在这捕捉到错误，并且是空错，大家快帮我看看！！谢了void ADOConn::OnInitADOConn()
{
//初始化OLE/COM库环境
::CoInitialize(NULL);
try
{
m_pConnection.CreateInstance("ADOOD.Recordset");
m_pConnection->Open("driver={SQL Server};Server=127.0.0.1;DATABASE=ourdb;UID=g;PWD=g","","",adModeUnknown);
}
catch(_com_error e)
{
AfxMessageBox(e.Description());
// AfxMessageBox("ADOConn::OnInitADOConn()错误");
}
}
