Report Generator error.

Question

I had  a problem running this console application.
I tried to generate report base on template report and input parameters, then to save the results.
I am running this code and get an error:"Invalid object type."
Also I don't sure that the rest of the code is o.k.
Please let me know what I am doing wrong?
Thanks,
Amos
static void Main(string[] args)
string reportTemplate = string.Format(@"{0}INVOICE REPORT.rpt", AppDomain.CurrentDomain.BaseDirectory);
string reportResults = string.Format(@"test.rpt", AppDomain.CurrentDomain.BaseDirectory);
//add parameters here
ListDictionary parameters = new ListDictionary();
parameters.Add("V_BATCH_ID", "2031");
parameters.Add("V_INVOICE_ID", "0");
ReportCrystal report = new ReportCrystal(reportTemplate, reportResults, parameters);
public class ReportCrystal
public ReportCrystal(string reportTemplate, string reportResults, ListDictionary parameters)
ReportDocument reportDocument = new ReportDocument();
ParameterField parameter;
foreach (System.Collections.DictionaryEntry param in parameters)
parameter = new ParameterField();
parameter.Name = (string)param.Key;
parameter.DefaultValues.Add(param.Value);
reportDocument.ParameterFields.Add(parameter);
reportDocument.SetDatabaseLogon("userName", "Password", "serverName", "DB", false);
reportDocument.Load(reportTemplate);
reportDocument.ExportToDisk(ExportFormatType.CrystalReport, reportResults);

I also try to do this:
reportDocument.SetParameterValue((string)param.Key, param.Value);
instead of:
parameter = new ParameterField();
parameter.Name = (string)param.Key;
parameter.DefaultValues.Add(param.Value);
reportDocument.ParameterFields.Add(parameter);
and got exeption ("Database logon failed") at:
reportDocument.ExportToDisk(ExportFormatType.CrystalReport, reportResults);
do I miss something?

Hi,
Vital information is missing -
CR Version?
VS Version?
Web or Windows app?
Database?
Database connection - ODBC, OLEDB ?
Also before exporting try to view the report and check the exact error.
