Invalid Parameter

[ZuperDuper]

Why would I get an Invalid Parameter exception when trying to open up a CR9 in vb.net on 2000 machine, but it works fine on XP?! I have no idea what the problem is

I have checked data types, so they would match, report can be viewed fine on XP through vb.net or through Crystal Reports software. I am using 7 different reports and they all act same way.

Iam using Access database. I wonder if anyone ran into simmillar problem here...
Can anyone help please?

Hmm, I am looking through the report for the 7th time and just noticed that one fields type comes up as a number type if i hover mouse over it. It does store values that could be numbers, but the field in the database is set to text.
Interesting thing is that if I try to delete the label from the report, and drag a new one from the FieldExplorer, it still ends up as a number. Weird.
Once again it works fine in XP and does not in 2000. Pardon my French - kraP.

Hmm, I actually figured out where the error is coming from, although I dont know why and dont know how to fix it yet...

form3 = New Form3
With form3.CRVIEWER9
.ReportSource = ("C:\Program Files\dc analysis reports\othcount.rpt")
.Show()
form3.Enabled = True
form3.Show()
form3.Text = "All Files in QC directory"
.Visible = True
End With
The erro occurs on the line Form3.show() which doesnt make much sence since error itself is reffering to the report viewer.: Error in ("C:\Program Files\dc analysis reports\othcount.rpt") : INvalid Parameter Name. Crystal Report Windows Forms Viewer.

Now, I know that I might need to talk to someone in vb.net forum about this, but still if anyone have any idea, please let me know.

I believe the problem is here:
[tt]
.ReportSource = ("C:\Program Files\dc analysis reports\othcount.rpt")
[/tt]
The ReportSource property is expecting a Crystal Report object, not a path to a report.

Try taking a look at the .Net samples:

Thanks for the link it is pretty nice. The thing though, is that one of the examples is previewing the report that way. They just assign the path to the report object. And it does work under XP, but not 2000. I will try various other methods that they provide examples for.

Dim repDoc As ReportDocument = New ReportDocument

Try
repDoc.Load(Path) <-------
Catch ex As Exception
MessageBox.Show(ex.Message, "xxx",MessageBoxButtons.OK, MessageBoxIcon.Error)
Me.Cursor = Cursors.Arrow
Return
End Try

 

[ZuperDuper]

Am I supposed to set the CRViewer source to repDoc?

[ZuperDuper]

I tried
Try
repDoc.Load(path)
.ReportSource = repDoc
.RefreshReport()
Catch ex As Exception
MessageBox.Show(ex.Message, "xxx", MessageBoxButtons.OK, MessageBoxIcon.Error)
form3.Cursor = Cursors.Arrow
Return
End Try

Still same problem, it works fine on XP though. Maybe it is a problem with DLLs? How would find out what is missing, since I am getting same error, which does not refer to anything at all? Try-Catch does not help.

Thanks, to all. I've resolved the issue.

Hi ZuperDuper,

You close by saying you solved the problem. I am just finding the same problem between my 2000 PC and our XP PCs.

How did you solve the problem??
