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.

ScriptErrors opening (a new tab of) IE10 on a Windows 7 machine

I’ve been running into the error message on the right (“Unable to get property ‘style’ of undefined or null reference”) when opening an instance or a new tab of IE10 for the past couple of weeks. It didn’t matter what start page I used, since I tried about:blank, and approximately a dozen more. I found out McAfee SiteAdvisor was the cause of this error pretty quick, but since the company I’m currently in doesn’t allow users to disable SiteAdvisor and I needed IE10 for some testing purposes, I had to find a different solution to the problem. I found a workaround which will do for now: in IE10, go to ‘Tools’ then ‘Compatibility View Settings’ and check ‘Display all websites in Compatibility View’. This will, as you imagined, open all pages in Compatibility View which causes the errors to stop popping up. It is not an ideal solution, but it’s better than closing a script error message for every single IE instance or tab that is opened. Besides, it’s pretty easy to get IE to render as true IE10 in stead of Compatibility View by changing the browser mode to IE10 in the F12 developer tools. Good to know: after changing browser mode to normal IE10 in a tab, the error doesn’t occur in that tab for the current or subsequent pages you visit while it maintains the Browser Mode. Of course new instances and new tabs will have Compatibility View enabled again. Hope this helps

Error: The Path ‘path’ is already mapped in workspace ‘workspace’

Just a quick little post today: I got the error “The Path ‘path’ is already mapped in workspace ‘workspace'” when I connected to a new Team Foundation Server and tried to map my workspace today. I had connected to a Team Foundation Services project a while back to get some shared code, but I already removed the workspace and the server binding. Even though Visual Studio didn’t see any other bindings, mapping my workspace to the same folder the previous TFS binding was mapped to served me this error. The quick solution: manually edit (or remove if you don’t have any other bindings) the file VersionControl.config, which can be found under %AppData%LocalMicrosoftTeam Foundation4.0Cache Hope this helps.
