you are not connected to a company

Hi all,

I have build an application to insert data in SAP. Initially it is working fine but after every 1 or 2 hour it is getting the error

"you are not connected to a company".

My code to connect company is like this.

oCompany.Server = "xyz"

oCompany.language = BoSuppLangs.ln_English;

oCompany.DbServerType ='dst_MSSQL2005';

oCompany.DbUserName = sa;

oCompany.DbPassword = password;

oCompany.CompanyDB = abc;

oCompany.UserName = sa;

oCompany.Password = password;

int ResponseCode = oCompany.Connect();

please help me.

Thanks in advance
