  Properly checking if an item in a folder is a Directory or not in PowerShell

  I got a great tip from a colleague on how to properly check if an item is a file or a directory. In one case we weren't really ever sure if another script had finished its running and unzipped a certain zip package into a folder, and we had to verify it had, before continuing the execution. Our initial implementation worked most of the time... But not quite always. The purpose of this blog post is to explain how we found a pretty well-working and elegant solution!

  Disabling requests to WsaUpload.ashx (Customer Experience Improvement Program)

  So, I've gotten this question from a lot of customers and partners, and I thought it would be worth clarifying the case a bit. "I'm seeing a lot of requests these requests to WsaUpload.ashx . What do they matter? They seem to degrade the performance - so what can I do about them?" That's a great question! Let's see what it is, why it exists, and what we can do about it!

  Subscribe to changes on a SharePoint list

  SharePoint List Alerts . That magnificent functionality in SharePoint gives you a heads-up anytime someone touches your precious documents (so you can go and revert the changes) or changes files in Style Library (so you can go and remove that pink custom CSS they tried to add). Very useful for a lot of scenarios! The functionality is ancient, quite cumbersome, and CERTAINLY not pretty, but it's straightforward and quite reliable.

  How to get the user count for Azure AD Enterprise Application

  Have you ever tried to find out the number of users of an enterprise application in your Office 365 tenant? This could be needed for multiple different reasons: maybe your organization is paying for the app and you want to know who's actually using it, maybe the usage is required by a company policy and it's useful to know if the organization's members are actually using it, or maybe you just want to know about the user adoption of an app.

  Solving the "Tenant app deployment is only supported in the app catalog site." error

  Solving "Sorry, your files couldn't be uploaded. The upload might be too large or the server might be experiencing high network traffic." in SharePoint

  This is one of the weird issues that you don't really run into in your own development environments, but that you more often run into when you actually have non-godlike permissions. Oh, the woes of trying to use SharePoint with anything less than farm/global administrator... :) Anyway, in this post, I'll describe a couple of solutions to an error: "Sorry, your files couldn't be uploaded.

  5 ways to enable Custom Scripts for a SharePoint site collection

  How to show more than 30 categories on Classic SharePoint blog/news sites?

  Imagine this: you're using a good old SharePoint blog site, and have a bunch of categories in use. That's nice and easy - SharePoint offers the categorization functionality natively, and it works decently. Problems arise when you have a lot of categories, though - not all of them will be shown. Even if you tweak the web part to show more items on a page, this isn't reflected on the whole blog site! This article explains how to fix this in a couple of simple steps!

  A cautionary tale of relying on the automatic backups in SharePoint Online

  Microsoft keeps 14-day rolling backups of your SharePoint Online sites. That's awesome - no need to take backups anymore, right? Not so fast. It's not always so easy, and by just relying on these backups, you risk losing your data. Forever, I might add. This cautionary tale is about SharePoint Online, but I'd say you'll need to take caution anytime you're dealing with Microsoft's automatic backups.

  How to fix Twitter embed in SharePoint

  Twitter has always been (relatively) good for developers - except for anyone who'd like to embed anything - hence making it possible to interact with their content on other sites than Twitter. I guess it's understandable, but they seem to hate anyone trying to embed feeds, searches, or anything on their sites. And they express their hate by making the developers' lives more difficult... This time by silently breaking the embed script in a way, that's tricky to work around.

  Fixing an unhandled exception about StructureMap configuration failing (messed up assembly bindings)

  So, you're running a console program, but while you try running it, you get an error like this: " StructureMap.Exceptions.StructureMapConfigurationException ", with a message like this: " Unable to find the exported Type's in assembly " (the typo done by Microsoft, not me). There are a number of reasons for this error, but for a fair share of the time, that's just your assembly bindings being messed up. Luckily, that's another easy fix!

  How to show a pop-up in SharePoint
