Stored Procedure not called on .refreshreport

[DeniedABrain]

I'm new to Crystal Reports and don't really know what I'm doing.
I have a vb.net windows app with a reportviewer.
I've designed a report with cr9 which gets it's data from a stored Procedure. the stored Procedure has three input parameters. When I refresh the report in the designer, I am prompted for values for the parameters, then the sp is called and the report is refreshed.
When I open the same report in my app, it prompts for the parameters, then displays nothing in the report viewer.
I added logging to the sp so that I could check what values are being passed to the sp, but the sp doesn't even get called when the report is refreshed. I have save data with report turned off.

I've tried adding in a routine to loop through the parameters and manually request them from the user. This still presents a blank report.

My code is:

Private Sub Display_Report()
Dim crDoc As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
With crv
.ReportSource = txtPath.Text
.Refresh()
.Show()
End With
End Sub

I've tried it without the .Refresh(), without the .Show(), even with .RefreshReport() All to no avail.

Thanks for your help.
