Document Library- Item Event Listener

I have created a Document library in SharePoint 2010 site. Now I 开发者_JAVA技巧want to execute some code whenever new document is added to this Document library.

How do I implement this? Do I need to implement Item Event Listener? and how this Item Event Listener will be connected to Document library. Can I call a Web service into Item Event Listener?

Be careful reading links that pertain to sharepoint 2010. Sharepoint 2007 links may contain out of date logic.

• In how they dispose of SPSite/SPWeb objects
• Not using properties.Cancel
• EventFiringEnabled instead of DisableEventFiring()

For binding the receiver to a list

And it you have the permissions right, you should be able to do most things in an event receiver. Look into elevating the user context.
