I am using vc + + programming, accounted to connect the oracle database, the user name system, the password manager is no problem, use up sqlplus login also no problem, use accounted programming has a problem,
With navicat connecting oracle,



Role in the top window is set to sysdba can connect,

The code is as follows:

Const string userName="system";
Const string pass="manager";
Const string connectString="192.168.1.2 instead/former";//IP address and service names for

Oracle: : accounted: : Environment * pEnv=oracle: : accounted: : Environment: : createEnvironment (" ZHS16GBK ", "UTF8");
The Connection * pConn=pEnv - & gt; The createConnection (userName, pass, connectString);

Program execution to Connection * pConn=pEnv - & gt; The createConnection (userName, pass, connectString); After the mistake,
Error messages are:
ORA - 01017: invalid username/password. Logon denied
