Re^5: fetching and storing data from web.

Finally using manual methods suggested I was able to build WWW::Mechanize::Firefox on Win32 to the extent that 'use WWW::Mechanize::Firefox;' in and out of itself does not cause an error.
However the object itself can not be created:
use WWW::Mechanize::Firefox;
open STDERR,'>>out.txt';
my $mech = WWW::Mechanize::Firefox->new();
##########################
output:

The languge of my op. system is not english so the error message rougly means: 'connection failed because the destination computer refused to establish connection'. This message popped up during the build many times by the way. Note I've installed the necessary plugin for Firefox (mozrepl) and Firefox was running when I've received this message (I switched off the firewall but to no avail).
Any thoughts on that? | [reply] [Watch: Dir/Any] [d/l] |

Is your browser running the MozRepl extension?

I've just googled the english part of the error message and it turned out that this is a typical problem for lamers: it is not enough to install the mozrepl extension but you have to explicitly run it or set the option 'Activate on startup' :). Now I'm able to open a web page. But it is still not clear how to use this module to submit a form or login to some site. Is there any tutorial on this that you recommend?

This looks very interesting. I would be happy if I could use such high level modules for web browsing.
However on my Win32 this is the said result of the build:
CPAN: CPAN::SQLite loaded ok (v0.199)

The following are modules that would be nice to have, but not required

This is why I want to be able to achieve my goals with the simplest possible means without relying on high level modules. | [reply] [Watch: Dir/Any] [d/l] |

It must be doable because both WWW::Mechanize and WWW::Mechanize::Firefox are available using ActiveState's ppm package installer. The build processing for getting modules into shape for packaging seems a little fragile so as a rule if a module is available using ppm it's not hard to install using cpan.
Have you tried installing with force?
True laziness is hard work

I don't know how to install with force. The readme which comes with strawberry says that at command prompt I should type 'cpan ModuleName' to insatll a CPAN module.

Look, chances for WWW::Mechanize on Win32 at ActiveState are not the best. Only an older version is available for an older version of Perl itself. So I'm forced to switch to an older version of Perl if I want to use this module.
I've tried cpan help also: it suggest to use -f and -i switches together or force / fforce before the command. But the result is the same: the build not only fails but freezes.
Actually I've switched from ActiveState to Strawberry. With Win32 I've had to get used to the fact that not all moduels are available to me. It seems there is no fix for that.
