Question An error occurd during local report processing

[ADH]

The Local Report (.rdlc) I designed, returns on some data ranges with this error

"An error occurd during local report processing".

How can I please find out which data elment (SQL 2005) is causing the problem?

 

[ADH]

Empty ReportViewer Control

I have a VB2008 working report, desplaying data of several sorted dates. But sometimes I get an empty report with

"An error occured during local report proccessing.
An unexpected error uccored in Report Proccessing.
Object Reference not set to an instance of an object."

When selecting the same dates separately everything is fine and no data is missing. So is the underying SQL query. I have digged a lot to find the reason (data?) but could not find any.
Q:
Is there a way to find (log?) what bothers the control?

If you set the code to break when the exception is thrown, and then look at the call stack, it may have info that you can use along witha product called Reflector, to decompile the relevant framework code and identify the problem

Empty Report (VB)

My problem is that no Exception is thrown what forever, just the remark at the empty report.
Thanks

re: an error occurred during local report processing. Object reference....

Hi,
I'm reposting this Q: 1) It's still unsolved and delaying the installment.
2) I found a VB2008 + SQL2005 solution at:
http://support.microsoft.com/default.aspx?scid=kb;en-us;959595&sd=rss&spid=12913#appliesto
But I need it for VB2005 + SQL2000 !!
The original problem:
I have a VB.net2005 winform project with a local rdlc report.
Occassinaly I get a blank report with the error:

"an error occurred during local report processing. ... Object reference not set to an instance of an object."

I tried unsuccessfully (a long time now..) to figure out the problem.
When I Systematically am deleting row after row from the Report bindingsource the report will display,
But I cann’t find any reason in those rows which are identical in all means (row fields all OK)!!

Could someone assist me please how to seek for the specific problem?
Does the report generator leave behind any log of it's doings?
