How to give user an option of clearing a report field once print button is clicked

Hi All,

I have the following code to generate a report in my app: Once a user clicks a company on a listview the populate report sub is called. I pass the companyid to the report sub and use that as the recordselectionformula.

my sql query in designer for the report.

the user wants the option to clear a follow up date field on the report once the print button is clicked. I no crystal has an event which is fired once the print button on the crsytalviewer is clicked. How can I allow for a certain field to be either included or excluded. Please help.

I am using CR XI.

Code:

---

Public Sub lvwCompany_Click()

If (lvwCompany.ListItems.Count > 0) Then

    CoNum = CInt(lvwCompany.SelectedItem.Text)

End If

If (CoNum > 0) Then
    Call LoadContacts(CoNum)

    Call PopRep("({Command.ipkcompanyid} = " & CoNum & ")")
    CrystalActiveXReportViewer1.Visible = True
   
    cmdAddContact.Enabled = True
    cmdAddCall.Enabled = True
End If

End Sub

---

Code:

---

Sub PopRep(FilterSql)


    lvwCompany.Enabled = False

    Set oReport = New CrystalReport1
    oReport.EnableParameterPrompting = False
    oReport.DiscardSavedData
    oReport.FormulaSyntax = 0
    oReport.RecordSelectionFormula = FilterSql


    CrystalActiveXReportViewer1.ReportSource = oReport
    CrystalActiveXReportViewer1.ViewReport


    Delay 2 'give report time to load otherwise it fails if user clicks on listview twice while reportviewer is loading

  lvwCompany.Enabled = True

  Set oReport = Nothing

End Sub

Personally I think it might be easier to do it the other way round. Let the user choose what he wants to see before you run the report.

That way you can send parameters into the report telling it what fields to suppress/show based on their selection.
