Module development and code questions

Hi, i am developing a CRM system in php/mysql and i was wondering if I can use the security/authentication system of drupal without completely rewriting it as a drupal module. I would like to lauch a complete application in a new window. Is this an option?

Can someone out there point me to an explaination of how the db_query function works? I've been all through this site and can't find the documentation on it. I'm just trying to do a simple "select x from y where z", and I'm pulling my hair out.

thx

Thanks for looking into this.

To get the amazon.module working with amazon.de and the german language you have to edit the file AmazonSearchEngine.class.inc in the include directory.
2 changes have to be done:

var $server = 'xml-eu.amazon.com'; // was xml.amazon.com @Line#9

and

$url = "http://{$this->server}/{$this->server_xml_url}?{$version_text}t={$this->associates_id}&dev-t={$this->dev_token}&locale=de"; 
//appended &locale=de @Line#100

Thats all!

I discovered Problems with the amazon module and maybe more modules.
You will not see the amazon settings in admin/system/modules after activating it.

The problem is the missing informations in the amazon_system(...) function.
You will need at least something like

function amazon_system($field){
  $system["description"] = t("Make use of the webservices of Amazon.");
  $system["name"] = t("Amazon");
  $system["link"] = t("Amazon");
  return $system[$field];
}

After you have insert these variables in the amazon_system(..) function in your amazon.module you can make the needed settings and sell items through your site.

Apparently, the blog feed is not including the
tag. It would be nice if the module would do this, so that readers who subscribe to a blog via an RSS feed would know when particular items were published.
