Code or idea of adding date range parameters

Question

Thanks guys for answering all my past queries.
Another question arises
I don't know how to write code for date range value parameters for a report.
i-e
I have a report that takes a start date and end date range parameter.
I can pass all the other parameters to CrystalReportViewer through code but dont know how to write code to pass date range parameters.
Please help!

Hi,
I assume you are using JRC on CR XI or XI R2.
For Single Range Values:
Calendar calendar1 = Calendar.getInstance();
calendar1.clear();
calendar1.set(yyyy,mm,dd);
Date date1 = calendar1.getTime();
Calendar calendar2 = Calendar.getInstance();
calendar1.clear();
calendar.set(yyyy,mm,dd);
Date date2 = calendar2.getTime();
// use yyyy,mm,dd,hh,mm,ss for DateTime parameter.
ParameterFieldValue rangeVal = createSingleRangeVal(date1, date2, RangeValueBoundType.inclusive, RangeValueBoundType.inclusive);
paramFieldController.setCurrentValue("", "<Parameter Name>", rangeVal);
For Multiple Range Values:
Object [] beginVals = {date1, date2, date3};
Object [] endVals = {date4, date5, date6};
//Where  date1 - date4 is range 1, date2 - date5 is range 2 and date3 - date 6 is range 3.
RangeValueBoundType [] beginBoundTypes = {RangeValueBoundType.inclusive, RangeValueBoundType.exclusive, RangeValueBoundType.noBound};
RangeValueBoundType [] endBoundTypes = {RangeValueBoundType.noBound, RangeValueBoundType.inclusive, RangeValueBoundType.exclusive};
ParameterFieldValue [] multiRangeVal = createMultiValRangeParameter(beginVals, endVals, beginBoundTypes, endBoundTypes);
paramFieldController.setCurrentValues("", "<Parameter Name>", multiRangeVal);
I hope this helps.
Thanks
