No exception object

[Jon]

I don't know what's going on...but I have a function within a class that
loads a crystal report. The report fails to load for some reason, but the
odd thing is that when the debugger goes into the catch statement, ex =
Nothing...what could be happening? This is in VS 2005 with crystal XI R2.

Here's the function:

Public Sub LoadReport(ByVal FilePathAndName As String)
Try
rptActive = New ReportDocument
rptActive.Load(FilePathAndName)
Catch ex As Exception
Throw New Exception("Report load failed" + Environment.NewLine +
ex.Message)
End Try
End Sub

Jon,
Interesting, it sounds like a bug in Crystal XI R2!

It sounds like Crystal XI R2 is throwing Nothing, however I don't think that
is even allowed by the CLR!

In VB, the following results in a NullReferenceException:

Dim anException As Exception = Nothing
Throw anException

Are you using the released version of VS 2005 or one of the betas? If your
using a beta, does the same thing happen in the released version?

Unfortunately you may need to contact MS and/or Crystal support directly.

This is the released version of VS 2005 and XI R2. If I put "Throw New
Exception("gg")" line in the same procedure, it catches that just fine.
