Crystal Reports Record Selection Questions

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?

Sincerely,

Marko
