Problem connecting to a company

Hi,

I am using the following code to get a connection to a company

//  Initialize the Company Object.

            //  Create a new company object

            oCompany = new SAPbobsCOM.Company();

            //  Set the mandatory properties for the connection to the database.

            //  To use a remote Db Server enter his name instead of the string "(local)"

            //  This string is used to work on a DB installed on your local machine

            oCompany.Server = "TS0022-LAPTOP";

            oCompany.CompanyDB = "SBODemo_US";

            oCompany.UserName = "manager";

            oCompany.Password = "manager";

            oCompany.language = SAPbobsCOM.BoSuppLangs.ln_English;

            oCompany.DbUserName = "sa";

            oCompany.DbPassword = "SAPBUSINESSONE";

            int valor = oCompany.Connect();

            //  Check for errors during connect

            int transTemp6 = System.Convert.ToInt32( lErrCode );

            oCompany.GetLastError( out valor, out sErrMsg );

            if ( lErrCode != 0 ) {

                Interaction.MsgBox( sErrMsg, (Microsoft.VisualBasic.MsgBoxStyle)(0), null );

            }

            else {

                Interaction.MsgBox( "Connection Established", MsgBoxStyle.Information, null );

            }

but in this line:

int valor = oCompany.Connect();

I get -125, I search in the SAP Business One DI API 9.0 - Objects Reference (9.00.052)  GetLastError Method help and didnt find any information about this code.

What is wrong in my code?

Regards.
