VC++oracle数据库连接问题

Question

CString strConnection;
strConnection.Format("Provider=OraOLEDB.Oracel;Password=%s;User ID=%s;Data Source=%s;Persist Security Info=TRUE;","thh129111","system","thw");
hr=m_pConnection.CreateInstance(_uuidof(Connection));
if(SUCCEEDED(hr))
{
hr=m_pConnection->Open(_bstr_t(strConnection)," "," ",adConnectUnspecified);
}
上面是我的连接程序,运行后总是出现"unknown error 0x80010e7a"的错误.上网找了一下,有人说在oracle目录下加个internet账户就可以了.可我加了之后也没好.
请高手指教.

Answer 1

把你的代码换成如下："Provider=OraOLEDB.Oracle;Password=%s;Persist Security Info=True;User ID=%s;Data Source=%s"
CString strConnection; 
strConnection.Format("Provider=OraOLEDB.Oracle;Password=%s;Persist Security Info=True;User ID=%s;Data Source=%s"); 
hr=m_pConnection.CreateInstance(_uuidof(Connection)); 
if(SUCCEEDED(hr)) 
{
hr=pConnection->Open(strCon,"","",NULL);
}

为什么不试试Pro *C/C++这样的方式呢？
