Hi John,

I have installed the new version of OLE::Storage and it now works.

The properties.xls file generated by properties.pl opens fine, as well
as files generated by my application.

Thanks for the quick response, and all the hard work on S::WE.

Cheers,
Richard.

Hi,

It turns out that the problem was caused by an external patch that I
applied to the OLE::Storage_Lite module shortly after I took over
maintainership. In 2004!!.

It only occurs when creating OLE documents (in this case Excel files)
less than 7MB and only on Windows 7 (32 and 64 bit).
Spreadsheet::WriteExcel uses its own OLE creator for files less than

Hi,

Just to let you know that I think that I found the general problem in
OLE::Storage_Lite and that I am working on it.

It will take 2-3 days to fix and test.

I'll keep you informed in this thread.

Hi,

I have a Win7 environment set up now and I can reproduce the bug.

It is in the OLE::Storage_Lite module, which I maintain but didn't
write, and it will probably be tricky to find.

I post any progress in this thread.

Hi,

I'll look at it in more detail over the weekend. In the meantime could
you try the following program and let me know if it causes problems:

#!/usr/bin/perl -w

use strict;
use Spreadsheet::WriteExcel::Big;

my $workbook = Spreadsheet::WriteExcel::Big-> new('olelite.xls');

Hi John,

I made the changes to Storage_Lite.pm as you showed, but it still
doesn't work. I tried changing line 378 first and it didn't work, so
I changed 377 as well.

I had a look at the file generated by properties.pl, and the header is
exactly the same. The value of $iSDBcnt must be evaluating to 1,

Hi,

Thanks for the kind offer but I should be okay. If I run into problems
I may get back to you.

Hi John,

Not a perl savvy but have been using S::WE for a while now. If you have some
time, I don't mind doing a webex session with you and providing a Win 7
environment where you could make the changes and test it out. I am in EST
zone.

Hi Richard,

Thanks, that indicates that the problem occurs when using
OLE::Storage_Lite for files less than 7MB. In general this only
happens in S::WE when set_properties() is in use. (It may be possible
that the error doesn't occur for files over 4k that use set_properties
() but that probably isn't worth testing).

Hi John,

I have experimented with some of the examples, and have found that it
is using set_properties which causes the problem under Windows 7.

The sheet generated by the example program properties.pl will
demonstrate it for you.

I tried a_simple.pl, demo.pl and format.pl and they all worked fine.

Hi,

Excellent. Well done.

From reading through their response and patches it looks like an issue
with their port of OLE::Storage_Lite.

Which means that it will also affect WriteExcel but I should be able
to fix it.

Is it affecting all S::WE programs on Windows 7 or only ones that

Hi John,

I have just come across this issue myself.

It has nothing to do with 64 bit. It is a Windows 7 issue.

When I open a file generated by Spreadsheet::Writeexcel on Windows 7
in either Excel 2007 or 2003, I get the "Excel found unreadable
content" error. I can open the same file under XP, Vista or OSX

I run the 2.25 version under windows 2008 server x64 using Strawberry
Perl 5.8.x and it runs just fine, producing excel files that open
without issue...Have you tried the XP compatibility mode in Win 7?
