I have a report with a sub report in it. I have a parameter field in each that handles a date range in that sub report. How do I pass said date range from VB to that sub report? I would guess

    q = Format(dtFrom.Value, "yyyy-mm-dd") & " 00:00:00.000"
    r = Format(dtFrom.Value, "yyyy-mm-dd") & " 00:00:00.000"
    strParm = "date(mgmtprod.rpt); " & q & "," & r & "; TRUE"
    CR.ParameterFields(1) = strParm 'set the parm
    CR.Action = 1

Where dtFrom and dtTo are drop down boxes with dates in them. and date is the paramter name and mgmtprod.rpt is the sub report. When I run this I get invaild parameter name.

       Dim param1Fileds As New CrystalDecisions.Shared.ParameterFields
        Dim param1Field As New CrystalDecisions.Shared.ParameterField
        Dim param1Range As New CrystalDecisions.Shared.ParameterDiscreteValue

        param1Field.ParameterFieldName = "paraName"                   ' Parameter Name In Crystal Report
        param1Range.Value = Request.QueryString("parameter1")         ' value For Parameter Field
        param1Fileds.Add(param1Field)                                 ' To add parameter in parameterslist
        CrystalReportViewer1.ParameterFieldInfo = param1Fileds        'to pass parameters to report viewer
        CrystalReportViewer1.ReportSource = Request.QueryString("Path") ' Assign Report Source to the viewer
        CrystalReportViewer1.Visible = True

This uses the viewer. I need to use the OCX control. Does this even go for the sub reports?

I tried getting around it by creating a parameter feild in the main report and linking it to the parameter feild in the subreport but that doesn't work either.

I believe you have to pass the parameter to the main report.  For example if you have 2 parameters in the main report and 1 in the subreport then to pass the subreport parameter you would pass:

CR.ParameterFields(3) = strParm  (1 & 2 go to the main report).
