I'm trying to generate a report of a few columns (name, heard, date, country, and trip) on all of my sightings.  The report works fine, but when I try to save to a text file, after the "Counting forms" pass and the "Rendering" pass, I get a message box titled "Error saving file" with the message "Overflow (6)".  This happens on smaller (but still large) subsets of my sightings -- all since 2010, or all Passeriformes -- but if I choose a small enough set, such as one year, it works fine.

Interestingly, saving as RTF works, even though the resulting file is MUCH larger.

Can you explain what's overflowing and suggest any way to avoid it?

Judy

Here's another tidbit of data. I've tried lots of reports of various sizes, by varying the range of dates. Every report with 33412 records or more fails with "Overflow (6)" when I try to save it to text, while every report with 31766 or fewer succeeds. Is it a coincidence that the magic number of 32768 is between those two numbers? Is there an array or other structure that's limited to that number of elements?

Hi Judy,

BINGO! I must be using a 2 byte integer for a counter somewhere in the Text output format.

Working to find the error and reproduce right now. I should have a fix in about an hour.

Sorry for this. 

I will update here when ready.

Hi Judy,

Fixed in Build 99 - available now! Help | Internet: Check for a program update from Birder's Diary.

You must be the first ever in the history of BD to attempt to save a Sightings Report with > 32k sightings to Text format!!! Congratulations!!! 

Thanks for finding the bug.

Take care and stay safe,

Jeff

Jeff, I can't tell you what a pleasure it is to report a bug in commercial software and have it fixed within hours rather than months or even years.

However...
I updated and tried generating a report and got this Fatal Error message:
RecordCount not good in frmReportPreview2!getSelectLabel:
0
Latest Error Properties: 0 =

Thank you Judy! And uh-oh.

I wonder how that happened. I do have a couple other changes rolled into Build 99, but nothing that I remember in Reporting.

Can I get onto your computer to see this? In about 2 hours? I have to head out for a bit.

Jeff, I have Zoom meetings at 7 and 8 (it's now 6:45 here). If you want to connect at around 9 that would be OK; otherwise, tomorrow after mid-morning.

Update: Got onto Judy's computer. There seemed to be some irregularities that I saw on the computer. However, after stopping and restarting and building a report from scratch, we could not reproduce the problem anymore. All was working.

Sometimes...
