TppTextPipeline - data file not closed after report

rbuser

I am creating a text file from within my application, it is then closed
before producing a report using a TppTextPipeline. All is well except when
the report is closed, the text file is not. I am unable to then overwrite
the file.

Using Win '98, Delphi 5 and reportBuilder 5.56

Any help welcome. Thank you.

Take a look at the main reports demo # 135 - it does exactly this. Can you
run this demo? We aren't able to reproduce the problem with the demo.
Perhaps you could try to use our approach or provide us with some code to
see what it is that you are doing? The approach in demo 135 works, so if you
could follow this technique to get it working that that would be the first
step to take before trying to debug your approach.

Thanks for the reply. I looked at demo 135 and found the only major
difference between and what it and I were doing, was that the form with the
report and textpipeline on it was dynamically created and destroyed each
time the report was run in the demo.
I have followed this approach and it works fine.
It appears the text file is not closed unless the form (and therefore the
report) is destroyed and freed. Could this be the case?

Thanks again and regards,
John.

Place a breakpoint in TppFileDataStream.Close to see if it is getting called
after you are done printing. This is where the file stream is freed and the
text file should be closed automatically.

You shouldn't need to open the file before printing, since the pipeline will
do this internally. You can also try closing the file after the print is
over. Use the TppTextPipeline's OnClose event to close the file.
