Module development and code questions

The menu hook of the node module, since version 5.0, makes use of something I haven't seen before - the % character in paths.

This is clearly a technique to allow paths whose arguments aren't necessarily at the very end of the URI, but in the middle - as in node/%/edit. Very useful.

Unfortunately, I've been unable to find this feature in the documentation. Can someone tell me how this is used and how the parameters get passed to the callback function?

i created a product module which add a new product content type.

i also created a taxonomy vocabulary (hierarchy:multiple, required) and assigned a list term to each product created.

what is the best module to help me to create an automatic hierarchical menu to access the products ?

Alright, I recently downloaded the gallery module to put on my website and everything seemed fine until today when I actually started implementing the module. Take a look at my website http://www.aviationflightzone.com . You will notice that on the left side there is a block named Random Image and at the bottom of the page there is a grid displaying additional photographs. One thing that I have noticed with the newsportal theme is that it will let pictures eat the page up.

I developed a "core" hack fro Upload.module and wanted to make it a module but have spent the last 4.5 hours hitting my head trying to figure it out.

Basically I want to append some extra data in front of the output of theme_upload_attachments()

Here is my Basic hack to Upload.module:

Hi

Please advice as to which player is better to be used for drupal video module. Should I incorporate a Windows media player or a flash player. ..........or there exists any other better option as well.

I am getting the following error message:

>>
Fileview module fileview index: 8 - upload index: 20
fileview module is loaded before upload module. replacement of attachment table won't work since upload module will overwrite attachement table of fileview module. Change the weight of the fileview module to load after the upload module.

I don't really understand what the message means, or what I can do about it. How do I change the weight of a module?
