Running Visual Studio as an administrator causes ‘Save changes to devenv.sln’ when double clicking solutions

After making sure my Visual Studio always ran as an administrator by following my own post HowTo: Have Visual Studio always run as administrator on Windows 8, I got a message if I wanted to save changes to devenv.sln each and every time I double clicked a Solution. Since the problem kept occuring after installing Visual Studio 2015 CTP6, I wanted to solve it. So here we go! Double clicking a Solution file doesn’t start devenv.exe (which is set to be run as an administrator) but will cause the Microsoft Visual Studio Version Selector (VSLauncher.exe) to be run. This tool selects the right version of Visual Studio to open the Solution. Because VSLauncher.exe is not being run as an administrator, the error occurs. The Solution Find VSLauncher.exe, which is typically located at ‘C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv’ and make sure it runs as an administrator too. This will cause the Version Selector to be started with the correct privileges, helping it start devenv.exe with the right privileges. Problem solved 😉 Hope this helps

Scheduled build launches an hour early on TFS 2013 (after installing Update 3 or 4)

There’s new information in this issue. Please read the updates at the bottom of the article. We use our own TFS server and were using TFS 2013 Update 2 up until last Tuesday. We have several build definitions for my current project, and most of them are scheduled at a specific time, because we have specific times for automatic deployment. Up until Tuesday, everything seemed to work well and the Builds ran at the specified time (both before and after Daylight Saving Time applied). And then I installed Update 4… The issue After installing Update 4, our scheduled builds ran an hour early. Of course I checked both the time on the server and the time the build was scheduled for: these were fine. I looked at the Update 4 documentation, but couldn’t find anything related. I did see however the build server report its time setting as UTC +01:00, and the build definition stating UTC +02:00.Next up was searching the web, which pointed me to an article on Scheduled build launched 1 hour earlier. As a comment on this article, which is from July last year, Microsoft employee Mario mentions the issue is fixed in the (at that time) RC of the Summer Update. He also mentions: Once you install that Update on the server please recreate/re add the build definition and the database will now respect the right times. Visual Studio 2013 Update 3 & 4 Since we were using Update 2, I looked at the documentation of both Update 3 and Update 4. And if you go to the New technology improvements in Visual Studio 2013 Update 3 chapter and look at the Fixed issues paragraph you find this for Team […]

Error saving Galileo Wiring App in Visual Studio

Last week I received my Intel Galileo board (from and I started playing with developing for it yesterday. I created a first test project, but it didn’t run. Visual Studio couldn’t find the Arduino header file, which was probably due to a missing NuGet package (the Galileo C++ SDK). I tried to save the project, because you need to before you can manage NuGet packages, but to no avail. Visual Studio served me a ‘The operation could not be completed’ error without any additional information. A while ago I posted about some handy settings in Visual Studio like Zero-impact projects & Cutting/copying empty lines. Turns out that the Windows for IoT project template does some extra things upon creation. And with the ‘Save new projects when created’ checkbox unchecked, it’s not able to do that. Rendering the project unsaveable…   The solution It’s as easy as it is ugly to have to do this: simply check the checkbox in ‘Save new projects when created’ before creating your Windows for IoT project. Then you’re good to go…! Hope this helps

Fixing the Remote Desktop Connection to a Virtual Machine in Microsoft Azure

A few minutes before my second session at the Dutch Techdays started I tried connecting to my Virtual Machine in Microsoft Azure through remote desktop. It didn’t connect… The RDP client tried to connect to the Virtual Machine, but nothing happened. So I rebooted the VM and tried connecting again, confident that this would solve the problem. It didn’t connect…. again. As I started stressing out a bit (the VM was the main character of my session) I thought of one last thing I could try. Fixing the issue The next steps helped me save my Virtual Machine without too much loss of time (I was able to connect again just before the start of my session!): Go to the Azure Management Portal Open up the details of the VM you’re having trouble with Go to the ENDPOINTS tab (see image below) Select the ‘Remote Desktop’ endpoint and click EDIT at the bottom of the screen Change the public port to a different (random) number Wait for the changes to be propagated Success! Hope this helps.

Error comparing historic versions of a TFS source controlled file

When working with Visual Studio 2012 on our current project, the error ‘These files are not text files and cannot be opened in the comparison window.’ shows up every now and again. I’ve tried several things to solve this problem. Here’s the one that works: Close Visual Studio Navigate to your version of the ‘c:\users\{username}\AppData\Local\Temp\’ folder Delete the TFSTemp folder Restart Visual Studio and try again. You should be good to go! Hope this helps.

Getting Bootstrap to work on Windows Phone 8

There are a couple of websites I manage that use Twitter Bootstrap*. These websites are fully responsive and work well on all devices. Or actually, almost all devices. The wrapping of columns in a container on a Windows Phone doesn’t work the way you’d want it out of the box. Windows Phone interprets device-width as the actual resolution size. Other mobile browsers use what the manufacturer (or browser vendor) has decided is the optimal viewport width. To fix this issue, follow these steps: Add this line to use –ms-viewport in your CSS file @-ms-viewport{ width: device-width; } Add this line to the head tag of your HTML page (it’s probably already there since you’re using Bootstrap) <meta name="viewport" content="width=device-width, initial-scale=1" /> Add this JavaScript function as the first script in the head tag (because of a timing issue it won’t work if it isn’t the first script) (function() { if ("-ms-user-select" in && navigator.userAgent.match(/IEMobile\/10\.0/)) { var msViewportStyle = document.createElement("style"); msViewportStyle.appendChild( document.createTextNode("@-ms-viewport{width:auto!important}") ); document.getElementsByTagName("head")[0].appendChild(msViewportStyle); } })(); I found this solution over at Matt Stow’s blog ‘Firewoiks’. You can find the original article here. Hope this helps. * The Bootstrap project is no longer under the Twitter brand. Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world. – about Bootstrap

Speaking at TechDays 2014

I’m proud to announce that this year I’ll be speaking at the TechDays in the World Forum in Den Haag, April 16 – 17. This session will be about High Performance Computing in Windows Azure. Camera resolutions keep increasing, your digital behavior on websites and in apps is collected, images that satellites make get more and more detailed and (research) equipment produces more data. The amount of data that’s being stored keeps increasing. This data often has to be processed to become information. With increasing amounts of data to be processed the need for a Cluster like solution to achieve this within acceptable time grows. With the rise of the Cloud you don’t need to have that Cluster in the basement anymore, but you can leverage the power and capacity of the Cloud. In this session you see how High Performance Computing in Windows Azure can be used to distribute processing tasks to multiple machines in Windows Azure.
