Maintainer(s)' notes

If you are reporting a bug in Spreadsheet::WriteExcel here are some pointers

1) State the issues as clearly and as concisely as possible. A simple program or Excel test file (see below) will often explain the issue better than a lot of text.

2) Provide information on your system, version of perl and module versions. The following program will generate everything that is required. Put this information in your bug report.

    #!/usr/bin/perl -w

    print "\n    Perl version   : $]";
    print "\n    OS name        : $^O";
    print "\n    Module versions: (not all are required)\n";

    my @modules = qw(
                      Spreadsheet::WriteExcel
                      Parse::RecDescent
                      File::Temp
                      OLE::Storage_Lite
                      IO::Stringy
                      Spreadsheet::ParseExcel
                      Scalar::Util
                      Unicode::Map
                    );

    for my $module (@modules) {
        my $version;
        eval "require $module";

        if (not $@) {
            $version = $module->VERSION;
            $version = '(unknown)' if not defined $version;
        }
        else {
            $version = '(not installed)';
        }

        printf "%21s%-24s\t%s\n", "", $module, $version;
    }

    __END__

3) Upgrade to the latest version of Spreadsheet::WriteExcel (or at least test on a system with an upgraded version). The issue you are reporting may already have been fixed.

4) Create a small but complete example program that demonstrates your problem. The program should be as small as possible. At the same time it should be a complete program that generates an Excel file. If the Spreadsheet::WriteExcel section is part of a much larger program then simplify it down to the essentials. Simulate any DB reads with an array.

5) Say if you tested with Excel, OpenOffice, Gnumeric or something else. Say which version of that application you used.

6) If you are submitting a patch you should check with the author whether the issue has already been patched or if a fix is in the works. Patches should be accompanied by test cases.

Subject: Problem writing to stdout

Thanks for the great modul. We use it to generate spreadsheets in a web application framework, based on Oracle, Apache and Perl. Today we reached the 7 mb limit, upgrade to current module versions solved the problem after some code change: original we used binmode(STDOUT); $ms_excel = Spreadsheet::WriteExcel->new('-'); .... $ms_excel->close; which faild as cgi application, worked well on command line with redirected output to file. The message in apache error log was: malformed header from script. Bad header=\xd0\xcf\x11\xe0\xa1\xb1\x1a\xe1: report.pl changeing the code to binmode(STDOUT); $ms_excel = Spreadsheet::WriteExcel->new(\*STDOUT); .... $ms_excel->close; solved the problem. It seems do be a difference how stdout is used on a windows box, maybe this is just a winows feature, or a small documentation bug. Environment used: Perl version : 5.006001 OS name : MSWin32 Module versions: (not all are required) Spreadsheet::WriteExcel 2.37 Parse::RecDescent 1.965001 File::Temp 0.22 OLE::Storage_Lite 0.19 IO::Stringy 2.110 Spreadsheet::ParseExcel 0.2602 Scalar::Util (not installed) Unicode::Map (not installed) This is perl, v5.6.1 built for MSWin32-x86-multi-thread (with 1 registered patch, see perl -V for more detail) Copyright 1987-2001, Larry Wall Binary build 638 provided by ActiveState Corp. http://www.ActiveState.com ActiveState is a division of Sophos.

Hi MArtin, Thanks for that. The difference for files > 7MB is that Spreadsheet::WriteExcel uses OLE::Storage_Lite to write the OLE container and that uses IO::File (from memory) to handle filehandles. I'll update the docs to include the safer \*STDOUT option. Thanks, John. --
Fixed in version 2.38. On its way to CPAN. Thanks.
