I'd like to create a module in DNN that, similar to the Announcements control, offers a template that the portal admin can modify for formatting. I have a control that currently uses a Repeater control with templates. Is there a way to override the contents of the repeater ItemTemplate, HeaderTemplate, and FooterTemplate properties? ...
This has me puzzled. This code worked on another server, but it's failing on Perl v5.8.8 with Date::Manip loaded from CPAN today. Warning: Use of uninitialized value in numeric lt (<) at /home/downside/lib/Date/Manip.pm line 3327. at dailyupdate.pl line 13 main::__ANON__('Use of uninitialized value in numeric lt (<) at /home/dow...
Hello, I intend to develop a system that is entirely based on modules. The system base should have support for finding out about plugins, starting them up and being able to provide ways for those modules to communicate. Ideally, one should be able to put in new modules and yank out unused modules at will, and modules should be able to u...
I've run into what appears to be a variable scope issue I haven't encountered before. I'm using Perl's CGI module and a call to DBI's do() method. Here's the code structure, simplified a bit: use DBI; use CGI qw(:cgi-lib); &ReadParse; my $dbh = DBI->connect(...............); my $test = $in{test}; $dbh->do(qq{INSERT INTO events VALUES (?...
I'm trying to figure out a way to make user controls run in their own UI threads. Is this possible? I'm trying to prevent a module-based application from crashing due to a single module. Any thoughts? ...
How do you find the version of an installed Perl module? This is in an answer down at the bottom, but I figure it important enough to live up here. With these suggestions, I create a function in my .bashrc function perlmodver { perl -M$1 -e 'print "Version " . $ARGV[0]->VERSION . " of " . $ARGV[0] . \ " is installed.\n"' $1 } ...
I have a large collection of retro games consoles and computers, I want to create some sort of catalogue to keep track of them using Drupal. I could do it as a series of pages in Drupal, but would rather have some sort of more structured method. It'd be great if I could somehow define a record consisting of certain fields (manufacturer,...
The __debug__ variable is handy in part because it affects every module. If I want to create another variable that works the same way, how would I do it? The variable (let's be original and call it 'foo') doesn't have to be truly global, in the sense that if I change foo in one module, it is updated in others. I'd be fine if I could set...
I've seen a number of postgresql modules for python like pygresql, pypgsql, psyco. Most of them are Python DB API 2.0 compliant, some are not being actively developed anymore. Which module do you recommend? Why? ...
Some people want to move code from user space to kernel space in Linux for some reason. A lot of times the reason seems to be that the code should have particularly high priority or simply "kernel space is faster". This seems strange to me. When should I consider writing a kernel module? Are there a set of criterias? How can I motivate...
Ok I have two modules, each containing a class, the problem is there classes refrence each other. Lets say for example I had a room module and a person module containing CRoom and CPerson. The CRoom class contains infomation about the room, and a CPerson list of every one in the room. The CPerson class however sometimes needs to use t...
A lot of useful features in Python are somewhat "hidden" inside modules. Named tuples (new in Python 2.6), for instance, are found in the collections module. The Library Documentation page will give you all the modules in the language, but newcomers to Python are likely to find themselves saying "Oh, I didn't know I could have done it ...
When it comes to organizing python modules, my Mac OS X system is a mess. I've packages lying around everywhere on my hdd and no particular system to organize them. How do you keep everything manageable? ...
Every time I make a project I develop several generic routines/modules/libraries that I expect I'll be using with other projects. Due to the speed of development I don't spend a lot of time making these modules perfect - just good enough for this project, and well enough documented and isolatable that I can easily add them to another pr...
In our product we have a big utilities file that we require (with do) at the beginning of a lot of our files. Is there a reason not to turn this into a module? For example, instead of doing this: do '../dbi_utilities.pl'; our ($db,$user,$pw,$attr); my $Data = DBI->connect($db,$user,$pw,$attr) or die "Could not connect to database: $DB...
I have a module in the parent directory of my script and I would like to 'use' it. If I do use '../Foo.pm'; I get syntax errors. I tried to do: push @INC, '..'; use EPMS; and .. apparently doesn't show up in @INC I'm going crazy! What's wrong here? ...
I have a Flex application where load time is extremely important (consumer site). i want to be able to get something up on screen and then allow additional modules to be loaded as necessary. The issue I'm facing is that the sum total of all the modules is much larger than if i were to include all the components in a single .swf file. I...
I couldn't really find this in Rails documentation but it seems like 'mattr_accessor' is the Module corollary for 'attr_accessor' (getter & setter) in a normal Ruby class. Eg. in a class class User attr_accessor :name def set_fullname @name = "#{self.first_name} #{self.last_name}" end end Eg. in a module module Authentica...
People keep giving me examples with carp instead of warn. Why? What makes carp better than warn? ...
If I define a constant in a Perl module, how do I use that constant in my main program? (Or how do I call that constant in the main program?) ...
