Hi,

I am creating a new program to generate and export the Crystal report as xls using C#. I have created a rpt file using CR binding to xsd.  The requirement is the rpt and the xsd should not be included in the solution. During the runtime, I am loading the rpt file and assigning hte dataset. But I am getting the error Logon Failed during the time of export
The Error is in the line ExportReport.Export.ObjRpt.Export

Please advise
public void Load()
        {
            string ConnectionDetails = GetConfigSetting("Connection");
             ReportDocument _CrystalReport;
            _CrystalReport = new ReportDocument();
 
            _CrystalReport.Load(@"C:\\Report1.rpt");
 
            SqlConnection Connection = new SqlConnection(ConnectionDetails);
            SqlCommand Command = new SqlCommand("GetDATA", Connection);
            Command.CommandType = CommandType.StoredProcedure;
 
	    SqlDataAdapter dsDA = new SqlDataAdapter(Command);
            DataSet dsReport = new DataSet();
            
            try
            {
                dsDA.Fill(dsReport);
                _CrystalReport.SetDataSource(dsReport);
                
            }
            catch (Exception Ex)
            {
                Console.WriteLine("Exception ocurred in LoadData \n {0}", Ex.Message.ToString());
            }
 
       
                    try
            {
            ExportReport rptExp = new ExportReport("xls", "C:", "test");
 
            rptExp.Report = _CrystalReport;
 
            string _exportedFile = rptExp.Export();
            Console.WriteLine("File [{0}] successfully exported", _exportedFile);
        }
        catch (Exception Ex)
        {
