SPFeatureReceiver Guidance

CAUTION! This is starting to become a PET PEEVE of mine!

Features can be managed from stsadm.exe, Site collection features web ui, Site features web ui, console apps, powershell scripts, feature staplers and the list goes on and on.
To make sure your feature receivers work no matter where the feature is being activated from do yourself a favour and keep on reading.


SPFeatureReceiverProperties.Feature.Parent can be many things depending on the scope of your feature and where it's being activated from so please make sure you check before using it. So many times have I found great features in CodePlex that I would like to staple to site definitions or deploy/activate using powershell or other mediums and find I get this.

Value does not fall within the expected range. at ###.###.FeatureReceiver.FeatureActivated(SPFeatureReceiverProperties properties)

For Site Scoped Features

public override void FeatureActivated(SPFeatureReceiverProperties properties) {
SPSite site = properties.Feature.Parent as SPSite;
if (site == null)
{
SPWeb web = properties.Feature.Parent as SPWeb;
if (web != null)
site = web.Site;
}
if(site == null)
return new ArgumentNullException("Can't find a refrence to a site!");
//Or check for parent being a Web app or log it

// Do Stuff
}

For Web Scoped Features
public override void FeatureActivated(SPFeatureReceiverProperties properties) {
SPWeb web = properties.Feature.Parent as SPWeb;
if (web == null)
{
SPSite site = properties.Feature.Parent as SPSite;
if (site != null)
web = site.OpenWeb();
}
if(web == null)
return new ArgumentNullException("Can't find a reference to a web!");
//Or check for parent being a Web app or log it

// Do Stuff
}


You get the idea! (I'll format the code as soon as I'm back on my normal PC)

HRESULT: 0x80040E2F the Why and How

Just a quick update an why I was getting this error and how we fixed it. By WE I mean my bestest buddy ol' pal Angela Knight. Will post a link to her blog as soon as she starts one!

What it was is a custom Contentype that was based off the OOB Event ContentType with a bunch of custom SiteColumns where the offending SiteColumn was of type lookup. Problem was the custom ContenType was deployed to the SiteCollection level however the look up list was only provisioned at the web level.

So how did Ange fix it?
She removed the offending SiteColumn, Created a Web level ContetType thats based off our custom ContentType that's provisioned after the look up list is. Thus we no longer get the error. See the juicy bits below.

..oops.. out of time will update tomorrow <<such a tease>>

C# PriorityQueue<T> Implementation

Before I get any more abusive comments. This post is targeted at the 2.0 version of the Framework.

Guess I could of just used a SortedList<T1, T2> implementation in System.Collections.Generic, but I want a PriorityQueue<T>. So here goes.

public class PriorityQueue<T> : SortedList<T, T>
{
public PriorityQueue()
: base()
{
}

public PriorityQueue(IComparer<T> comparer)
: base(comparer)
{
}

//
// Summary:
// Returns the object at the beginning of the System.Collections.Generic.Queue<T>
// without removing it.
//
// Returns:
// The object at the beginning of the System.Collections.Generic.Queue<T>.
//
// Exceptions:
// System.InvalidOperationException:
// The System.Collections.Generic.Queue<T> is empty.
public T Peek()
{
return this.Last().Key;
}

//
// Summary:
// Removes and returns the object at the beginning of the System.Collections.Generic.Queue<T>.
//
// Returns:
// The object that is removed from the beginning of the System.Collections.Generic.Queue<T>.
//
// Exceptions:
// System.InvalidOperationException:
// The System.Collections.Generic.Queue<T> is empty.
public T Dequeue()
{
T item = this.Last().Key;
this.RemoveAt(this.Count - 1);
return item;
}

//
// Summary:
// Adds an object to the end of the System.Collections.Generic.Queue<T>.
//
// Parameters:
// item:
// The object to add to the System.Collections.Generic.Queue<T>. The value can
// be null for reference types.
public void Enqueue(T item)
{
this.Add(item, item);
}
}

SharePoint and me

This about sums it up for me,

Thank you Peter for an excellent analogy.

HRESULT: 0x80040E2F Why Me?

How did it happen?

I tried to edit an existing SPListItem through the Web UI.

What now?
I reach for my search bar and find blah blah Violation of PRIMARY KEY constraint blah Backup blah Restore.

Shouldn't the API gracefully handle such an error?
Time to dig through the logs.
Event logs say nada but I found the following in SharePoint logs.

In here I saw the SQL Error Code 3621 which pretty much says "The statement has been terminated."

Normally I wouldn't be so worried but in this case it now happens a lot with separate items in this list.

Thinking maybe something has become corrupted I've tried a stsadm -o backup and restore into a fresh site collection in a fresh web application using a fresh content database, but hey the issue has been restored into the new site collection.

Any help and or suggestion would be greatly appreciated, what a way to start the new year at work.

On a great note my holiday was "O" for awesome! Chur Chur.
