hy, i have a problem with my database Oracle 10g on a linux pc with Suse distro.

I'm writing a software in c++ with Visual Studio 2008:

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {

    String^ connectionString = gcnew String ("Data Source=(DESCRIPTION= (ADDRESS=(PROTOCOL=TCP)(HOST= (SERVICE_NAME=AFTIDI)));User Id=user ;Password=psw");

        System::Data::OracleClient::OracleConnection^ conn = gcnew System::Data::OracleClient::OracleConnection(connectionString);


conn->Open(); } catch(OracleException^ ex1)
String^ err=ex1->ToString(); } catch(InvalidOperationException^ ex2)
String^ err=ex2->ToString(); }

    String^ queryString = gcnew String ("SELECT * INTO AFTBSKDA8");

        System::Data::OracleClient::OracleCommand^ command = gcnew System::Data::OracleClient::OracleCommand(queryString);

when the program arrive at the command conn->Open(); this is a Exception that say:

                err "System.Data.OracleClient.OracleException: ORA-12547: TNS: contatto perso

can you help me???
