Why don't you just install OOo and control it using the API?
I don't have control over the machines on which our app is running, so
the only thing I know for sure is that they'll have our app installed.
Also, the machines on the shop floor running our app don't have a need
for a full office suite, since they're collecting/generating the data
and only want to be able to export to Excel for review later on other
machines. Having them install OOo would probably be overkill. Of
course, there's the option of including the OOo installation within our
app's installation, but that would probably really grow the size of our
installer.
For similar reasons we wanted to avoid the MS Office automation
interfaces. Using them would require having the MS Office SW installed
on the machine where our app was running and we couldn't ensure that
either. Which is why we're looking for something to let us directly
write the binary file format and OOo seemed liked a good possibility.
My hope was to be able to only include the code necessary to save the
Excel file format. Then our installer doesn't grow very much, we're not
asking them to install other software on the machines and/or we're not
adding a lot of SW to the machines which isn't needed and wouldn't be used.
Would it be feasible to re-use the Excel file writing code from
OpenOffice? I downloaded the OO SDK and was scanning the developer's
guide, however, it seems to be coming from the approach of connecting
to a running OO instance as opposed to re-using OO code in your own
app (on a machine which wouldn't have OO installed).
If you really want to use parts of our source, there's a bit of an
overview of the Excel filter classes at
http://sc.openoffice.org/servlets/ProjectDocumentList under "Source
Code Documentation". It's not completely up to date, but it might help
to get started.
Thanks, I'll start there and see what I can find.
