Module development and code questions

I downloaded this simple hello world example module, and I installed it into my modules folder and enabled it in admin. According to the code, I am supposed to be able to do http://mydrupaldomain/hello and it will run. However, I get the page not found content instead.

What do I need to do to run this simple module?

Cheers!

Hi,

i am about to plan a module for drupal that will help me handling my small boat-club. There are several boats, harbours, captains and customers and of course some people that can arrange all those into bookings. Because of the possibility that there will be more than one people to handle the incoming order from my customers i would like to restrict the access to my boat-nodes. In fact there are 3 boats that are property of the club and up to 5 boats that belong to other people, but that have to be managed with my new module.

i´d like to know if will a module to introduce google co-op in our drupal-site.

thanks

Oskar Calvo.

Hi all.
I can't enable clean urls on my web site, so to use gsitemps, I've solved the problem uploading alternatively the following scripts.

The simpler:

     print file_get_contents(
         "http://www.diegobelotti.com/?q=gsitemap"
     );

This one needs a writable file in your site root called gsitemap.xml:

Hello,

I have been trying to update the creativecommons module (http://drupal.org/node/17497) . I have updated the forms using the form update module.

Can someone help me in debugging this? Look at the file here : http://pushkar.net/creativecommons.module.txt

Thanks

The category module ships with a taxonomy wrapper module which is supposed to invisibly maintain the taxonomy tables as categories are added and maintained.

I am getting this error message (It prints 4 times):

user warning: Unknown column 'Object' in 'field list' query: INSERT INTO term_node (nid, tid) VALUES (36, Object) in THIS_IS_MY_WEBSERVER_ROOT/httpdocs/includes/database.mysql.inc on line 120.

The records never get inserted into the taxonomy module.

I assume something went wrong during the wrapper install. Anyone know how to fix this?
