Crystal Reports Record Selection Questions

Question

Hi to all!

I have following problem:

In my application (Visual Studio 2008 - C# language - I AM NEWBIE AT C#), I have two GUI elements - date pickers (MonthCalendar class) and according to their selected values (dates) i would like to filter records in report. I've added parameters (dtDateFrom, dtDateTo - both of type DateTIme) to report and now:
1) How do I dyinamicly setup their values to contain values from previously mentioned MonthCalendar classes (I've setup event handler, tested it and it works fine) - the question is, how to fill report parameters?
2) How do I then refresh report to show new data?

Currently, the second problem is:
As I lanuch app or press "Refresh" toolbar button on report, I get date entrance window, which is invoked from Crystal Reports - HOW DO I DISABLE IT?

Please answer ASAP since I am in hurry and thanks in advance for answers!

Sincerely yours,
Marko

Ok I did some work and now I want to check if a report gets parameters. Therefore I wrote the code:[code] private void setReportDateParameter(String strDateFromFieldName DateTime dtDateFromFieldValue String strDateToFieldName DateTime dtDatoToFieldValue) { ParameterDiscreteValue pmdvDateFrom = new ParameterDiscreteValue(); pmdvDateFrom.Value = dtDateFromFieldValue; // sets date from parameter ParameterField pmfDateFrom = new ParameterField(); pmfDateFrom.Name = strDateFromFieldName; // sets parameter field's name pmfDateFrom.HasCurrentValue = true; pmfDateFrom.CurrentValues.Add(pmdvDateFrom); ParameterDiscreteValue pmdvDateTo = new ParameterDiscreteValue(); pmdvDateTo.Value = dtDatoToFieldValue; // sets date to parameter ParameterField pmfDateTo = new ParameterField(); pmfDateTo.Name = strDateToFieldName; // sets parameter field's name pmfDateTo.HasCurrentValue = true; pmfDateTo.CurrentValues.Add(pmdvDateTo); // adds date to to field's values ParameterFields pmfDateRangeFields = new ParameterFields(); pmfDateRangeFields.Clear(); // clears paramter fields array pmfDateRangeFields.Add(pmfDateFrom); // adds date from to param fields object pmfDateRangeFields.Add(pmfDateTo); // adds date to param to param fields object m_crViewerGoodBadMeters.ParameterFieldInfo = pmfDateRangeFields; // transfer created parameters to report // debug part Console.BackgroundColor = ConsoleColor.Black; // sets background color Console.ForegroundColor = ConsoleColor.Yellow; // sets foreground color //Console.Clear(); // clears console Console.WriteLine(Date From: {0} (MonthPicker) - {1} (CR Value) this.m_dtFrom this.m_crViewerGoodBadMeters.ParameterFieldInfo[0].CurrentValues[0]); Console.WriteLine(Date To: {0} (MonthPicker) - {1} (CR Value) this.m_dtTo this.m_crViewerGoodBadMeters.ParameterFieldInfo[1].CurrentValues[0]); Console.ResetColor(); // resets color //// **** END OF debug part // report refresh part m_crViewerGoodBadMeters.Refresh(); // refresh report controls m_crViewerGoodBadMeters.RefreshReport(); // refresh report contens // **** END OF report refresh part }[/code] and my question is: In lines for debug output (Console.WriteLine(Date From: {0} (MonthPicker) - {1} (CR Value) this.m_dtFrom this.m_crViewerGoodBadMeters.ParameterFieldInfo[0].CurrentValues[0]);) how do I rewrite this line so I will see the values inside CR's ParameterFieldInfo?
