For a while ago I needed to copy all files from a document library within a SharePoint 2007 site to the hard drive. So I didn’t need to copy files from SharePoint to SharePoint so I couldn’t use the stsadm -o export command or Chris O’Brien’s nice SharePoint Content Deployment Wizard. I came across the SPIEFolder application which should work with SharePoint 2007 and 2010. It has a site on codeplex: spiefolder.

PowerShell is a great tool. It helps in SharePoint administration and tasks automation. Today I needed to provision a webpart on many similar pages. This third-party webpart’s constructor instantiates a dataaccess service and uses a connectionstring which is stored in the web.config file. So the webpart creation failed until I found a way to load the configuration into powershell. First you can create a simple file powershell.exe.config, put it into $pshome (C:\Windows\System32\WindowsPowerShell\v1.

Thanks to Ryan for sharing powershell functions. I used New-SPGroup which I altered. Now You can define which permissions will be given to the new group. You can even create groups without default users. Here it comes: function New-SPGroup { <# .Synopsis Use New-SPGroup to create a SharePoint Group. .Description This function uses the Add() method of a SharePoint RoleAssignments property in an SPWeb to create a SharePoint Group. .Example New-SPGroup -Web http://intranet -GroupName "Test Group" -OwnerName DOMAIN\\User -MemberName DOMAIN\\User2 -Description "My Group" -Role "Read" This example creates a group called "Test Group" in the http://intranet site, with a description of "My Group".

I have used AngularJS for a while and to me this seems to be the best MVC javascript framework. Today I wanted to implement a search which uses an input and a hash query string like in google. The input value and url have to be synced like: index.html#?term=something To do this we have to inject $location into our angular control. See the Angular Guide about $location. Then we have to observe both the $scope.

For a while ago I needed to provide an alternative solution when Silverlight isn’t installed. I searched for javascript code for this and found this: A blog post about that: Piotr Puszkiewicz’s Silverlight Blog. Determining if Silverlight is installed using Javascript. A more advanced javascript function which can even determine the version of the Silerlight can be pulled from Silverlight.js library. I didn’t need to determine the version of Silverlight, so I wrote a simplified js function (but it works in all browsers): [sourcecode language=“javascript”] var isSilverlightInstalled = function() { var installed = false; try { installed = !

Here is another article in my JSOM series. For one month ago I showed how to alter a column’s ShowInDisplayForm property with JSOM. This time I’ll show a code sample for changing a column’s (field’s) display name. If you want to alter the displayname with Server Object Model, grab the code in the sharepoint.stackexchange.com: Change Field’s DisplayName in a List. [sourcecode language=“javascript”]var ctx = SP.ClientContext.get_current(), //SP.ClientContext field = ctx.get_web() //SP.Web .

Today I needed to “clean” a list, meaning to remove all list items. For some time ago I wrote a post about different ways of removing list items in bulk: Server Object Model, SPLinq and RPC. This time I had only the web browser. So I tried the jsom way. By the way, the javascript documentation for jsom on msdn is getting really good. Don’t miss that: How to: Complete basic operations using JavaScript library code in SharePoint 2013.

By now TypeScript shouldn’t be something one has to introduce. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. If you haven’t already done it, go and see the intro video for TypeScript, check out a tutorial and visit the typescript playground. There are other javascript libraries which extend javascript and are compatible/compile to javascript: Dart and CoffeeScript. To be honest I had never time to try those.

In SharePoint 2013 Preview there is a new type of field: GeoLocation which is, like the old SPUrlField, a pair of values. The geolocation is described as longitude and latitude. Unfortunately you can’t add this field in list settings. You have to create this in code. In the provided link you can find the code C# code which uses the Client Object Model. In another link you can find an example how to create the geolocation file using Server Object Model (in FeatureActivated EventReceiver).
