Hi, I am trying to launch a Crystal report from VB.Net code.  I have used 2 approaches:
Method 1: Created a form with a CrystalReportViewer control.  Then, in the caller function, I put this:
----------------------------------------
Dim frmCrys As New CrystalForm()
Dim oRpt As New Crystal.CrystalReport()  
oRpt.ReportFileName = "EDILOG1.rpt"
oRpt.ReportSource = Crystal.ReportSourceConstants.crptReport
frmCrys.CRViewer1.ReportSource = oRpt
frmCrys.ShowDialog()
----------------------------------------
The result of this is a message from the Viewer saying: Invalid Report Source.
(The rpt file is where it's supposed to be and works independently)

Method 2:
----------------------------------------
 Dim cr1 As New Crystal.CrystalReport()
 With cr1
  .ReportFileName = "EDILOG1.rpt"
  .DiscardSavedData = True
 .Action = 1
End With
----------------------------------------
This one gives me an COMexception which says: "Exception from HRESULT: 0x800A5035."
Debugging:ErrorCode is -2146807755
source is "Interop.Crystal"

How do I do this right? Am on the right track with either of these approaches?


As with everything at work, this has instantly become urgent, so even though it's probably easy, I'll offer 250 points.

I don't know if you're using windows or web application but check out these fully functional sample apps and then copy & paste & edit from there...

oh i think you are using wrong approach

There are two ways that you can bind your report to the viewer.
1.Strong typed reports
2.Unstrong typed reports

If you want to do strong typped reports.

1.Add your report to a project then
2. then After the application.run(new Form1);
put this
CrystalViewer1.reportsource = new ReportName();
Report Name is the name of the report that you see in the project exporer,

2. You can do it by using the report document object model
dim myreport as new crystaldecisions.crystalengine.reportdocument
myreport.load(Reportpath)

This will oad the report from your harddisk to the myreport. Then
CrystalViewer1.reportsource = myreport

The 2 of you have pointed me in the the same direction, which seems to work better, but I am using an Access database for the report data, and it tells me it can not log on.
I have not put a password on this database, so I don't know why it should fail.
Is this a requirement of doing it through this method? When I open the report directly it doesn't ask for a password.
