As I have been working to develop an event handler that will be used to mirror a Document Library, I’ve come across an interesting tid bit that was frustrating at first.

It’s worth mentioning that in MOSS 2007, Event Handlers execute in the context of the current user rather than the process user in SharePoint 2003 .

The event handler contained the following piece of code :
using( SPWeb web = SPContext.Current.Site.AllWebs[guid] )
{
// code
}

When running as an administrator, the event handler worked fine. However, if you switch to a non-administrative user that doesn’t have full control of the site, you’ll get a lovely exception. The problem is that you must have full control of the site to be able to use the AllWebs property.

To solve this, try the following code:

using( SPWeb web = SPContext.Current.Site.OpenWeb(guid) )
{
// code
}

Happy SharePoint Coding 😀
