GD::Graph::Bars how to separate bar sets

[PerlDiscuss - Perl Newsgroups and mailing lists]

I am using GD::Graph::Bars to make four bar graphs for each month. I
cannot figure out how to separate the sets of bars from each other. As it
is, I have 48 vertical bars (4 x 12) all in a row. I want to show some
separation between each set of four bars (4 bars for each month). I do not
see any settings to make this work, but it seems like an obvious need for
bar graphs.

This is how it looks now:

writing to a file

[PerlDiscuss - Perl Newsgroups and mailing lists]

Hi

I have a very simple cgi script that I have put onto a webserver. I want
to write to a log file when it is run. My problem is that the open file
command always fails (and I get the openFailed message in my browser).
(even if i try opening for input it fails). I have created the file called
log.dat in the same folder as the script (cgi-bin) and set attributes to
read/write using chmod.

Is there any easy way I can find out why the file cant be opened (is it
permissions?). Do I need to fully qualify the filepath? if so how do I do
that? Is it because I'm not allowed to have log files in the cgi-bin
folder?

Any help for an absolute beginner appreciated.

#!/usr/local/bin/perl

$Msg = ;

if( ! open (LOGFILE,  log.dat) ){
   $Msg = OpenFailed;
}
else {  
$Msg = OpenWorked;
#print LOGFILE $Msg;
close (LOGFILE) ;
}

print Content-type: text/html\n\n;

print EOF;

- Yes I am using DBI. That's perfect, I didnt realize they had this
functionality, but it makes alot of sense that they do. Thank you, thank
you.

 There are regex's and the tr/y functions/operators? But in this case you
 shouldn't use either and instead use binding (assuming you are using
 DBI, are you?).  Binding allows DBI/DBD which is very smart decide how
 the data needs to be quoted rather than attempting to do this manually
 which usually just leads to problems.

 http://search.cpan.org/~timb/DBI-1.42/DBI.pm#Placeholders_and_Bind_Values

 Alternatively if binding can't be used, there is the 'quote' method for
 handling this specific task (on same page as above).

CGI::Framework?

[PerlDiscuss - Perl Newsgroups and mailing lists]

Where can I find documentation, tutorials, examples for CGI::Framework -
the cpan documentation is not enough for me :)

CGI::Framework?

[PerlDiscuss - Perl Newsgroups and mailing lists]

Hello!

I'm going to write my first perl script and I need Session handling,
authentification and a simple cgi application.

I tried to use CGI::Framework but I hardly find any documentation about
this module except the one at cpan. I tried the example but when I submit
from my enterusername htm the Application doesn't call the
validate_enterusername like it is told in the documentation.

show job status

[PerlDiscuss - Perl Newsgroups and mailing lists]

Hi,

I have a CGI script that takes some time to finish searching the DB. In
the meanwhile, how do I show that the job is being processed?

I tried just simple printing the same, but it wouldnt show up until the
search is over. I tried using threads with the same result.

Thanks.
