Hi All

I have a VB.net 2005 app which uses MS Report Viewer to create reports

Occassionally I get the following error when changing to a different report

User code running on thread 196 has attempted to abort thread 3560. This may
result in a corrupt state or resource leaks if the thread being aborted was
in the middle of an operation that modifies global state or uses native
resources. Aborting threads other than the currently running thread is
strongly discouraged.

The error occurs in
ReportViewer1_RenderingComplete event. Code below....

Try

Me.ReportViewer1.SetDisplayMode(Microsoft.Reporting.WinForms.DisplayMode.PrintLayout)

Me.ReportViewer1.ZoomMode = Microsoft.Reporting.WinForms.ZoomMode.Percent
******** line where error occurs

mypath = ReportViewer1.LocalReport.ReportPath

If mypath = reportpath & "DailyCashFlow.rdlc" Or mypath = reportpath &
"Staff.rdlc" Or mypath = reportpath & "rebookings.rdlc" Or mypath =
reportpath & "SalesbyPaymentType.rdlc" Then

Me.ReportViewer1.ZoomPercent = 80

Else

Me.ReportViewer1.ZoomPercent = 90

End If

Catch ex As Exception

mymsgbox(ex.Message)

End Try

Any ideas

Regards

Hi Steve,

Based on my understanding, you get an error occassionally when changing a
different report for a ReportViewer control in your VB.NET 2005 WinForms
application. If I'm off base, please feel free to let me know.

You have mentioned that it is when you're trying to change a different
report in the ReportViewer that you get an error. But the sample code you
demonstrate doesn't change the current report in the ReportViewer control
at all.

I have performed a test based on your sample code but didn't reproduce the
problem you described.

FYI, to change the report in a ReportViewer control, you could set the
ReportViewer. LocalReport.ReportPath property to the file path of a
different .rdlc file. Note that you must call the ReportViewer control's
Reset method to reset the ReportViewer before you attach a different report
to it.

If the problem still exists, you may send your sample project that could
just reproduce the problem to me. To get my actual email address, remove
'online' from the displayed email address.

Hi Linda

Sorry about the lack of detail

In another routine I reset the the Reportviewer then set it to a local path
..rdlc then populate the datasource e.g
ReportViewer1.Reset()

ReportViewer1.ProcessingMode =
Microsoft.Reporting.WinForms.ProcessingMode.Local

If ReportViewer1.LocalReport.DataSources.Count > 0 Then

ReportViewer1.LocalReport.DataSources.RemoveAt(0)

End If

sql = "SELECT * from customers order by surname"

dtsales = getdata(sql)

dtsales.Columns.Add("myheading", GetType(System.String))

If dtsales.Rows.Count > 0 Then

dtsales.Rows(0)("myheading") = "All Customers"

End If

ReportViewer1.LocalReport.DataSources.Add(New
Microsoft.Reporting.WinForms.ReportDataSource("GeePosDataSet_Customers",
dtsales))

ReportViewer1.LocalReport.ReportPath = reportpath & "Customers.rdlc"

ReportViewer1.RefreshReport()

I only get the error on 1 computer and I beginning to suspect it may have
some hardware issues. I also only get the error when running the code from
within VB IDE not from running the application .exe

Hi Steve,

Thank you for your reply and the detailed information.

Since the problem only exists when it is run under VS IDE on one pc, you
may check what the differences are in the particular machine and other
machines.

Hope this helps.
