All my information is:

when I use oradirect 3.5, my program is runing on 64bit mode(compiled with x64) in vs2005(vc++8.0) on windows xp64.

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e)
{
this->oracleConnection1 = (gcnew CoreLab::Oracle::OracleConnection());
oracleConnection1->ConnectionString ="User ID=scott; Password=tiger; Data Source=testdb";
oracleConnection1->Open();
}

Additional information: Arithmetic operation resulted in an overflow.
on 32bit mode(compiled with x32), it no problem.

why?

I think it is caused by windows xp64?

hello i am getting same error.. any solution to this.

Do you use VC++ 8.0 as well?

I am using VS 2005 (C#) with OraDirect over a 10G client (non-direct mode).

I am using the corflags utility to force my app to run in 32-bit mode on a 64-bit OS. But when it tries to load the CoreLabs dll (on a Windows x64 system), I am getting this error:

"An attempt was made to load a program with an incorrect format."

Is this related to the issue brought up here? Is this something that is known? Could it be the client giving me this message? I haven't tried switching to direct mode.

Thanks.
