Question

I am trying to pass parameters from Visual Studio using VB.net to a Crystal report.

I am using the following code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    If IsDate(MaskedTextBox1.Text) Then
        Dim report As New invoice4

        report.SetParameterValue(0, gCustId)
        report.SetParameterValue("CustID", gCustId)
        report.SetParameterValue("inputDate", MaskedTextBox1.Text)

        Try
            report.DataSourceConnections.Item(0).SetConnection("", "" & My.Settings.storeCS, False)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

        gReport = ""
        With removenotice
            .CrystalReportViewer1.ReportSource = report
            .ShowDialog()
        End With
    Else
        MsgBox("Please Enter a Valid Date")
    End If
End Sub

but every time I run it gives me a prompt for:

Pm-?CustID
Which when entered then gives me a “Field Not None”

So I try to replace the first ParameterValue:

report.SetParameterValue(0, gCustId)
with
report.SetParameterValue(“Pm-?CustID”, gCustId)

It then gives me the error:
Operation illegal on linked parameter.

If I click okay it still promts me for the CustID and inputDate and ultimately gives me the correct report.

Any suggestions?

Thanks

Are you sure you are linking it correctly to the sub-report? I’m getting the impression that it has something to do with passing the parameter down to a subreport.

Did you try running the report without this line: report.SetParameterValue(0, gCustId) ?
