After installing Visual Studio 2012 Update 1, my Visual Studio stopped opening files in preview mode when I clicked them in the Solution Explorer. This setting seems to have changed with the installation of Update 1. To re-enable opening files clicked (once) in the Solution Explorer in Preview mode, go to ‘Tools’ – ‘Options’ – ‘Environment’ – ‘Tabs and Windows’. There, check the box under ‘Preview Tab’ – ‘Single-click opens files in the preview tab in:’ – ‘Solution Explorer (Alt + click to avoid previewing)’.

Twitter Bootstrap is a… “Sleek, intuitive, and powerful front-end framework for faster and easier web development.” One of the nice things in Bootstrap is you can use icons from Glyphicons. To use these, you can simply use this markup <i class="icon-fire"></i> to get a nice fire icon. Translating this into an ActionLink styled as a button in an MVC4 application would look something like the following: @Html.ActionLink("<i class="icon-fire"></i> Invent fire", "fire", new { @class = "btn" }) Unfortunately, this renders as follows:

In the past, when you had some XML document that you wanted to translate into classes we had to create / generate a schema based on the XML file. Next, we had to generate a class based on the schema with an external tool. Not all too user friendly and somewhat time consuming. In Visual Studio 2012 you copy the XML you want to create a class/classes for, place the cursor in a class file on the location you want the code to be added and select the following menu items: Edit – Paste Special – Paste XML as Classes.

My Microsoft Touch Mouse stopped scrolling in Visual Studio on my Windows 8 machine some time ago. Because this kills productivity, I wanted to fix the problem. After trying some things I found that the problem only occurred when I ran Visual Studio as Administrator. Searching a bit further I found this bug to be added to Microsoft Connect. I found a workaround for the problem: Go to the location where you have Microsoft Mouse and Keyboard Center installed Open up the properties of ipoint.

In my previous post about being unable to access the iis metabase I wanted my Visual Studio to ‘Run as Administrator’ on my Windows 8 machine. I only managed to get this working for the pinned taskbar icon and not for items in the jumplist or for items you open by double clicking them. The solution to check the box ‘Run as Administrator’ on the compatibility tab of the file properties for devenv.

I opened a solution in Visual Studio 2012 on my laptop running Windows 8, when I was presented with the error “The Web Application Project SomeWebProject is configured to use IIS. Unable to access the IIS metabase. You do not have sufficient privilege to access IIS web sites on your machine.” The user I was logged in with was a local administrator and was able to open up and use IIS Manager, but still I was presented with this error.

Just a small post today: as of September first I joined Betabit (site is in Dutch). After having had several employers in the last few years, this feels like coming home. On our way to do nice things…!

Just a quick one: if you have a textbox with a Calendar (extender) from the Ajax Control Toolkit and an associated PopupButtonID which is an image, the calendar won’t close when you click outside the popup. Use an input type=”image”or an ImageButton to solve this problem. Hope this helps.

When building an ASP application that generates Word documents, it was working fine on the local machine: A Windows XP installation with Office 2007. When we deployed it to windows 2008 (64 bit) and Word 2007 we saw that Documents.Open returned null. Other than this, there are no exceptions. The code that returned the error (simplified): Application app = new Application(); Document doc = app.Documents.Open(ref name); As it turns out, a 64 bit system stores temporary files in C:\Windows\Sys\WOW64\config\system\profile\Desktop folder.

When installing SQL Server 2008 R2 on a Windows XP (or, according to the comments, Windows 7) development machine that has been around for quite some time, I got an error stating an unhandled exception occured in the application (see image). The error showed up directly upon startup and read: An error occurred creating the configuration section handler for userSettings/Microsoft.SqlServer.Configuration.LandingPage.Properties.Settings: Could not load file or assembly ‘System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies.

When installing the Windows Azure AppFabric Tools for Visual Studio (found here), you might get the error message shown at the top, stating that Windows Server AppFabric is installed and that it is not compatible with this release of Windows Azure AppFabric Developer Tools for Microsoft Visual Studio 2010 – June 2011 CTP. It asks to uninstall Windows Server AppFabric and rerun this setup if you want to install Windows Azure AppFabric Developer Tools for Microsoft Visual Studio 2010 – June 2011 CTP.

When writing WCF services, most of us find ourselves writing quick test applications. To give you more time to do what a developer should be doing (adding business value to the project) the Visual Studio team added a WCF test client that can help you reach goals faster. This is not a very difficult application, but it does the trick and is more than sufficient for simple testing. The WCF Test Client can be found at this location (without the ‘ (x86)’ for x86 machines): C:\Program Files (x86)\Microsoft\Visual Studio 10.
