Am using crystal reports and the form that displays the report keeps asking me for a user login ID and Password. these codes are in the form that contains the crystal report viewer

sqlConn = new SqlConnection(Properties.Settings.Default.GEMConnection);
cr0DataSet1 ds = new cr0DataSet1();
param = new SqlParameter("@companyName", CusMeterReport.apostate);
da = new SqlDataAdapter("SELECT no,companyName,meterNo,fault,comments,date,MeterType WHERE companyName=@companyName",sqlConn);
da.SelectCommand.Parameters.Add(param);
da.Fill(ds.FaultyMeters);

cr0 c0 = new cr0();
c0.SetDataSource(ds);
crystalReportViewer1.ReportSource = c0;
