Crystal Reports crystal starter

Message

   Hi,
I am using crystal report for the first time an I am having some
trouble. I am using .net 2 , c# on VS 2005. I got a good recipt form
what I am trying  to do is to give a summary of goods recipt using
crystal report when user finish the order. SO the user can view it and
then print it out. 
I have added crystalreport.rpt in my project and in form_load methodI am using following code:
DataTable DT = new DataTable(); 

            string msConnection = "Password=xxxx;Persist Security Info=True;User ID=xxx;Initial Catalog=SGCDB_LIVE;Data Source=xxx"; 

            SqlConnection con = new SqlConnection(msConnection); 
           con.Open(); 

            string CmdStr = "SELECT * from SGC_STOCK where GRN = '11'"; 

            SqlDataAdapter Adpt = new SqlDataAdapter(CmdStr,con); 

            DT.Clear(); 

            Adpt.Fill(DT); 
            ViewStockReceipt cp = new ViewStockReceipt(); 

            cp.Database.Tables[0].SetDataSource(DT); 
            crystalReportViewer1.ReportSource = cp; 

            crystalReportViewer1.Zoom(1); 

But
I run the code nothing appears on the screen. I also want to disply the
supplier detail as well on the report which is in different table. Can
any one help me 
Thanks
