Visual Basic - Number of records exported?

Question

I am using Crystal Reports XI and can not find a a way to tell how many records are exported when running the exportToDisk? 
Basically, I want to
                cr.SetParameterValue("Paremeter1_id", nId)
                cr.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.Excel, xlsfile)
                do while cr.IsBusy
                          <DoEvents>
                Loop            
                If <numberOfRecords> > 1 and not <Cr.IsBusy) then
                    email xls
                end if
Also, is there a way to determine when the export has completed.  My object does not have the cr.isBusy?
This is in a loop that will be setting a report parameter, then exporting the report.  Once the export has completed, I am going to e-mail the xls and move to the next parameter in the loop.

I think we're finally getting somewhere.
Ok, I started from scratch on a newly create XP virtual workstation. I installed Visual Studio 2005 , then installed Crystal Reports Professional, then crxir2_sp4_full_build . When I launch VS 2005, Crystal Reports is not shown as an Installed Product and the Object browser is not showing the Crystal Reports Objects.
Here is something I just thought of, VS 2005 was installed from SQLServer 2005 CDs (Disk2).
Two problems I see right away (possibly 3):
1) Install Crystal Reports Professional - this version is nor licensed for development in .NET. As a matter of fact, it will not install the .NET assemblies
2) Then install crxir2_sp4_full_build - this should also not install the assemblies
3) VS 2005 was installed from SQLServer 2005 CDs  - I don't know what SKU of .NET this is. It may be that CR does not work with this SKU - there are only certain SKUs of .NET that CR will work with.
I am not sure where the assemblies are getting installed from as we do find them on your computer, but it could be from our runtime msi or msm files(?).
I'm not sure how far you want to go with this, but to confirm my statements above, you could download the eval Developer version of CR XI r2, install it and see if the assemblies get "wired" into the .NET environment (they should). If you want to try this, I'd recommend uninstall the current version of CR XI Pro. Then install the trial. The eval can be downloaded from here:

Alternatively, you could download CR 2008 eval and see how that works. For my money, I'd go with CR 2008 as even if the CR XI r2 Developer will work, I do not think you can purchase it anymore and you'd have to upgrade to CR 2008 anyhow. The CR 2008 eval can also be downloaded from here:
