In this post I want to share an unusual, nevertheless interesting conceptual idea of loading content from SharePoint 2013 apps on many pages. The original awesome concept was proposed and developed by my colleague Martin Villysson at Bool. The problem we are trying to solve SharePoint apps are great to extend functionality in SharePoint and integrate other systems (full page apps available through Site Contents), they also provide tools to enrich the default SharePoint experience by App Parts (Client Web Parts) and Custom Actions (additional menus).

Recently I have switched from VMWare to VirtualBox for my SharePoint Development. So far it really works good. I have prepared this guide for configuring VirtualBox for SharePoint-hosted apps. That means we need a new adapter with a static ip address. All the steps done inside the virtual machine are applicable for VMWare and Hyper-V, too. This guide does not cover the full configuration of the app environment, it covers only the network and dns settings needed for SharePoint-hosted apps on Premises in a Development machine.

Yesterday I had a little presentation about PowerShell basics in the SharePoint context. Here you can see the presentation I’ve published on slideshare. The text is in Swedish. [slideshare id=37316916&doc=sharepoint-140724063012-phpapp01&w=600]

PowerShell is powerful. You can write concise, well formulated, functional-style code. Recently I got the following quiz: You’ve got $100.

It is quite impressive what you can do with PowerShell [code language=“powershell”] 1.

This is a must-read for all SharePoint Developers who use Angular.

In our project we still have to support Internet Explorer 8. The CSS issues in IE8 are most difficult to debug and solve. You can not add a new rule in Developer Tools or toggle the state of an element to hover as in moder web browser dev tools. One solution that I’ve come up to today, is to add a style with javascript or jQuery, open the script pane in IE8 Dev Tools and add this line: [code language=“javascript”] $(’.

Recently an issue was reported about count mismatches in SharePoint 2013 Communities. The number of replies in category tiles sometimes is different compared to the community stats in the web part called “What’s happening”. The actual number of replies is 1 in the figure below. The user who has reported has tried to add, update and delete discussions and replies. I have invested some time debugging this issue. It would be pity to not share my findings.

I want to use shortcuts. I prefer the IntelliJ keyboard scheme. Which do you use?

I am reading Mobile HTML5 written by Estelle Weyle. It is an awesome recap and new knowledge about html, css and javascript. I want to highlight one of tips I got: Use the weakest CSS selectors (can be found on page 204). We all know, that inline CSS and !important are evil. They have a higher level of specifity and override the standard cascade of the CSS rules. If you use !
