LlPrintEnd


(Guest) #1

Hello,

I am currently attempting to export to an Excel file, and everything is going great until it reaches the LlPrintEnd, at which point everything hangs. Running in debug mode in Visual Studio (C++) shows that there is a exception of some sort, but I can’t dig down to see what the problem is. Has anyone else experienced this and found a solution?

Any help would be greatly appreciated.

Sincerely,
Adam Chettle

Viewing the disassembly of the code where the debugger breaks is an int3 which is a breakpoint instruction rather than an exception. So that answers the question of why I see an exception, my next question is why does it take so long for LlPrintEnd to finish? It seems to take an extremely long time, even on the smallest data set.

Are there some sort of optimizations that are available for this? I am currently using L&L10.

Any help is greatly appreciated.

Especially in the XLS export, according to readme statements and
announcements, there have been very great performance improvements
during the last versions.

So you should try the current LL version, it should be several times
faster.

The export modules all do most of their jobs when the “prin” job is
finished - they need to collect the whole information and create an
output file from it, so it’s normal that most of the time is spent in
LlPrintEnd().

Thank you for your reply,

I just find it odd that doing a text export passes through the LlPrintEnd almost instantaneously, but an Excel export can take close to 10 minutes on a small data set.

We may be upgrading L&L in the near future, but I am still wondering if there could be something else that would be slowing down the processing of just Excel files.

Have a great day,
Adam

Hi Adam,

10 minutes sounds pretty much. Are you sure LL-debug-mode is switched off?
Additionally as far as I remember (and Paul already mentioned) there have
been some remarkable performance improvements in the last versions. Maybe
you check it out with LL13?

Greetings,
Harry
