Hello Koen L,

There is no reason why such error would be thrown randomly except if an expected parameter returns NULL or DbNull for some reason. If you can isolate the problem in a runnable project, please open a support ticket, zip and attach it there, so we can review it and provide more info.

If that would be the reason then it would be easy to solve the problem.

When the user gets this error and requests the same report again it works just normal.
So it would be hard to believe that the incomming data has been changed between the time of error and the next request for the same report.

But lets assume that there is a field with a null value. Can't we see what field it is in the errormessage?

Hello Koen L,

Try running your project in debug mode with first chance exceptions turned on. This way Visual Studio should break when the exception occurs, so you can pinpoint the source of the problem, or at least you can provide us with a complete stack trace, in case the exception is not thrown by your code.
Additionally can you confirm that you are able to reproduce the problem on your end or does this only happen to some specific user? If it is reproducible, then please open a support ticket with a sample project.

All the best,

I also receive this error when trying to print and it seems very intermittent also.  I have been unable to track down the cause.

This may or may not be related. I have this code in a textbox on the report.

=IIf(priorTotal <> 0,(catTotal-priorTotal)/priorTotal,"zero")

It produces a divide by zero error every time even though there should be no division when priorTotal is zero..

Hi guys,

@Don: This behavior is by design and you can find more info in the following forum thread.

@Jamie: Generally intermittent errors are the hardest to track down and that is why if you continue to have problems, we would appreciate if you take the time to narrow down the steps that cause the issue or provide us with a runnable sample which reproduces the error.

Kind regards,
Steve

Hi Derrick,

Did you try the suggestion from the link in the previous post? Why do you think the IIF() function does not work correctly? Can you elaborate how you expect it to work and provide arguments? If you are having problems with certain expression, we would need it in order to advise how to address it.

Kind regards,
Steve
