0 comments

During the course of upgrading a search application database from SharePoint 2010 to SharePoint 2013 we encountered an error in PowerShell: Microsoft.SharePoint.Upgrade.SPUpgradeException: Action 15.0.80.0 of Microsoft.Office.Server.Search.Upgrade.SearchAdminDatabaseSequence failed And we traced it back down to this error in the ULS: SqlError: ‘The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object […]

Finding the IP Address of a Specific Network Adapter in Windows (and a rant about Hyper-V)

2 comments

We just recently made the switch from VMWare over to Hyper-V and I have found two things a bit surprising: 1.) Hyper-V performs better on my laptop than VMWare.  I was having issues with my computer locking up and moving to Hyper-V appears to have corrected it, and I can run more VM’s more quickly […]

SQL Query for Determining SharePoint ACL Sizes

0 comments

When a SharePoint Access Control List (ACL) size exceeds more than 64kb for a particular URL, the contents under that URL become unsearchable due to limitations in the SharePoint search engine.  The error most often seen is The Parameter is Incorrect which really helps to pinpoint the problem (its difficult to convey extreme sarcasm here, […]

Setting the Default Wiki Page in a SharePoint Wiki Library

0 comments

I’ve seen a number of blog posts about setting the default homepage in a wiki library, and most of them offer ways of accomplishing this task through PowerShell or through SharePoint designer.  Although I have become an ever increasing fan of PowerShell, I still prefer to stay away from it unless I’m trying to do […]

Showing All Pages in a SharePoint Wiki Library

0 comments

Opening a SharePoint wiki takes you to the wiki homepage, which is what most users want and expect.  Administrators, on the other hand, will occasionally need to see a full list of wiki pages in the wiki library.  Getting to this view is really easy, but you have to know where to look. The problem […]

Interactive Office 2010 Command Reference

0 comments

I believe it was Office 2007 that did away with the old menu system and toolbars in favor the Ribbon, which is really just a toolbar on steroids.  Upgrading from a pre-2007 edition of Office to 2010 or 2013 can be fairly traumatic for someone who is highly proficient with the old interface, as it […]

SharePoint, HTTP Modules, and Page Validation

0 comments

Sometimes I really believe that SharePoint actively thwarts my attempts to get it to do what I want.  First you look at something and say, wow, that should work.  Then you realize it doesn’t.  Then you have an epiphany and see a workaround.  And when you almost have that work around working… well then SharePoint […]

Optionally Running SPSecurity.RunWithElevatedPrivileges with Delgates

0 comments

I was writing some SharePoint code today where I needed to give people the option of running some code with elevated permission.  When you run code in an elevated fashion it normally looks like this: SPSecurity.RunWithElevatedPrivileges(()=> {     //Code to run }); It wasn’t a lot of code so I was initially inclined to do […]

Setting Boolean Values in a SharePoint SPItemEventReceiver

0 comments

One of the confusing things about implementing an SPItemEventReceiver that modifies properties on an SPListItem is that while you are given an actual SPListItem with which to work, you’re really not supposed to use it. Instead, you should be modifying properties in the AfterProperties property of the SPItemEventProperties parameter passed into the method. AfterProperties is […]

Browser Item Caching and URLs

0 comments

Ultimately you want the browser to cache things like Flash components, Silverlight XAP files, and images to avoid users having to download them each time they hit a page.  But during development it’s very useful to NOT have things cached so you are always looking at the most up-to-date file.  You can always turn off […]
