Hello colleagues,
I have a report which I use like Dashboard. The report shows quantity of bad events in my internal system.
If all is well the report shows: QTY of bad events = 0.
In bad situation the report shows: QTY of bad events = 10 (for example).
I try to set up output for the report (email or folder).
Because my report always has one record (0 or not) I couldn't use the standard method Cancel generation if no records.
Ok.
I have written Pre-generation script when a calculate result (<>0) and set variable result to 0 or 1.
But...
In any cases (result=0 or result=1) my output is working and generate file or send e-mail.

My code is
Quote:
@{
ReportOutput output = Model;
string result = "0"; //Set result to 0 to cancel the report.
}
@Raw(result)


I Execute Output and check Messages:
Quote:

20:14:15 Report result generated in '\Отчет по статусам.html'
20:14:15 Processing result file for output 'output (Folder Device)'
20:14:15 Executing Pre-Execution script.
20:14:15 The script returns:0
20:14:15 Report result generated in '\Отчет по статусам.html'
20:14:15 Rendering report...


I see "The script returns:0". But the output is not stopped. Why?

This is a bug that will be fixed in the 6.0 (coming this week).
As a workaround, you can cancel the report with the Cancel flag:
Code:
output.Report.Cancel = true;


but for generation in a folder, the report result file will be created anyway...
Note that you can also use a task (with the Step 'Rendering is done, before output execution') to handle what you need.
thanks 1 user thanked epf for this useful post.

Big thanks!
Before your answer I used rise an error divide by zero :)
int i = 0;
i = 10 / Int32.Parse(result);
