I created a report in stimulsoft in asp.net c#. I created a new connection and then new data source, and added an exiting stored procedure to it. then I assigned columns and parameters this data source to my report.my problem is that : when i create new sqlconnection manually the connection string is :

Data Source=my_pc-PC\my_servername;Integrated Security=True;Initial Catalog=my database_name

when i run my site in my pc every thing is good an work. but when i set my site on web service do i do any thing to show my report successfully. my code for run report:

Stimulsoft.Report.Components.StiText t = new Stimulsoft.Report.Components.StiText();
        t.Text = DateLabel.Text;
        string str4 = Decrypt(Request.QueryString["select_rep_"]);
        if (str4 == "1")
        {
            string str1 = Decrypt(Request.QueryString["fromdate_"]);
            string str2 = Decrypt(Request.QueryString["todate_"]);

            string ConnectionString = ConfigurationManager.ConnectionStrings["my_ejraConnectionString"].ConnectionString;
            string serverlocation = HttpContext.Current.Server.MapPath(string.Empty);
            StiReport myreport = new StiReport();
            myreport.Dictionary.Databases.Add(new Stimulsoft.Report.Dictionary.StiSqlDatabase("Coneection", ConnectionString));
            t.Text = DateLabel.Text;
            myreport.Load(serverlocation + "\\rep\\myreport.mrt");
            myreport.Dictionary.Variables["fromdate"].Value = str1;
            myreport.Dictionary.Variables["todate"].Value = str2;
            myreport.Dictionary.Variables["today"].Value = t.Text;
            StiWebViewer1.Report = myreport;
        }`enter code here`

is this code work without any change on web server?
