SharePoint

Why I prefer WebApplication deployments over GAC deployments

This article is written with scope on SharePoint 2013. With SP 2013 the default TrustLevel in the web.config is set to “FullTrust”. On previous version the value is “WSS_Minimal”. When you develop Farm-Solutions for SharePoint, you can deploy assemblies to the Global Assembly Cache (GAC) or configure the solution for a “bin-Deployment”. The bin-way puts assemblies into the bin folder of the WebApplication, where the solution is deployed to. You can switch the target of the assemblies by modifying the properties of a SharePoint project.

Custom field and UpdateFieldValueInItem()

Recently I was developing a custom field. To store modified values, the UpdateFieldValueInItem method has to be overwritten. In a normal way of clicking the submit/save button, the method is called and I can adjust the value for the field within the current item. The changes are submitted to the database later. But what if you want to modify items outside of the current item? Sure, you can do so would you think.

Creating a lookup field via elements.xml

This is another post to help me remember. And as a reference for all of you, who cannot remember how to create a SPFieldLookup via XML. <Field ID="{8b26ec41-b6c3-4327-0066-0c18c0768626}" Name="InternalName" StaticName="InternalName" DisplayName="Display Name" Type="Lookup" ShowField="Title" Mult="TRUE" List="Lists/LookupList" Overwrite="TRUE" /> When you provision a SPField via features, do not forget to add Overwrite=”TRUE”! Otherwise you’ll get an exception like this: 0x8107058aFehler beim Binden des Inhaltstyps ‘0x010200C7A18EB120BB4A00892E9E1EE9481C9B0067E475B6FDD54048B347370871443CAD’ an die Liste ‘/sites/rhtest/Lists/LookupList’ für ‘http://rhdevsp2013/sites/rhtest’. Ausnahme ‘0x80070057’.

Migrate SharePoint Blog to WordPress

As promised here, this is a follow-up post with the tool I developed for the SharePoint to WordPress migration. First, a screenshot: What is it, that we have to cover with a migration? Copying the posts is not enough. So I came up with this features: Features Copy posts Copy comments Copy resources like images and downloads Create needed tags and categories Modify links to local resource deal with https, if links are absolute on the source blog and mixed with http Using web services to connect to source and destination URL rewriting (covered by a WordPress Plugin) Delete all content from the destination blog (for migration testing) Replace strings (with Regex) a nice (WPF) GUI Description Originally I’ve build a plain console application.

Useful JavaScript to know when working with SharePoint Display Templates

This post has some really great examples for JavaScript helper methods and available properties for working with Display Templates in SharePoint 2013. http://dotnetmafia.com/blogs/dotnettipoftheday/archive/2014/02/26/useful-javascript-for-working-with-sharepoint-display-templates-spc3000-spc14.aspx If you ever had to decide if your script is running on a SharePoint Foundation, use this one: // Determine if the host is SharePoint Foundation if (!Srch.U.isSPFSKU()) { }

SharePoint App Deployment fails

Visual Studio does not tell you much if an app deployment fails. Fortunately SharePoint will log more information about the problem that occurred during the app deployment in the ULS-Log. So if you run into the “There were deployment errors.” exception, take a look at the ULS-Log. In this particular case SharePoint didn’t like my JavaScript: App Packaging: CreatePackage: Unexpected exception: There were errors when validating the App package: There were errors when validating the App Package.

The solution for warming up SharePoint

Most SharePoint Farms will have a solution for the long loading time after an Application Pool recycle or iisreset running. There are many different ways to preload websites, so your users have faster load times. So why another solution? There are some questions, that I think have not been dealt with before: Most solutions require some sort of Timer to be started (e.g. a Scheduled Task) When should the warmup occur?

SharePoint 2013 SDK

How could I miss the release of the SharePoint 2013 SDK in November? http://www.microsoft.com/en-us/download/details.aspx?id=30722 Anyway. Finally the non-preview version has been released 🙂

Building a Visual Studio project for SP2010/SP2013 (.NET 3.5/4.0)

In this post I will show you how you can use MSBuild to target your project for .NET 3.5 or .NET 4.0 and use a separate app.config file for each. My Warmup Tool is supposed to work with SP2010 and SP2013. To achieve that compatibility, I have to change the TargetFramework of the project to be able to compile, as well as the app.config so the application uses the desired Framework.

Speed up SharePoint Update Installation

Installing Updates for SharePoint 2013 will take a long time, if you don’t disable some services prior starting the update process by executing the hotfix exe file. To simplify the installation, and speeding it up, you can use a PowerShell script to stop the necessary services, and start the update. http://blogs.msdn.com/b/russmax/archive/2013/04/01/why-sharepoint-2013-cumulative-update-takes-5-hours-to-install.aspx You need to copy the code, and save it as e.g. Install_SharePoint_Update.ps1 in the same folder as the exe file.
