crystal reports and Delphi - changing selection criteria of sub report

I have a crystal reports xi report which has a main report and subreport. I wish to set the selection criteria within the subreport to select by date.

I am accessing the crystal report through the VCL from Delphi 2007  but am at a loss as how I can modify the subreport selection through the vcl.

Can anyone help?

Maybe this previous EE question can help you
Delphi 7 with Crystal Reports

Especially have a look at below code part in the Accepted solution
if (crRepObject.Kind = crSubReportObject) then
                  // get the sub report object
                  crSubRep:= ISubreportObject(crRepObject);
                  // open the subreport
                  crSubReport:= crSubRep.OpenSubreport;

Open in new window

You then treat the subreport as a report and change it just ike you would a report using crSubReport

Thanks for the suggested solutions. While they didn't solve my problem they did point my mind in the right direction.

I needed to access the subreport through the VCL. What I needed was:

CRreport.SubReports[1].Selection.Formula.Text := 'The selection formula'.
