How to set the guides (right-margin marks) in VS2012 text editors - text-editor

Is it possible to set the guides (right-margin marks) in the visual studio 2012 text editors without any extensions?
Edit: registry key HKCU\Software\Microsoft\VisualStudio\11.0\Text Editor doesn't work.
Any working solutions?

Now is the Paul Harrington's Editor Guidelines Extension for the Visual Studio 2012 available. So you have an extended context menu, where you can Add, Remove or Change Color of the guidelines.

Disable Highlighting of Strings in Visual Studio

All of my strings in visual studio are highlighted (see screenshot)
This makes it very difficult when i'm actually highlighting something or using the find functionality.
I cannot find an option for this anywhere, anyone know how to disable this?
This is Visual Studio Community 2017
Go to Tools > Options > Fonts and Colors. On the Display Items, find String and change the Item background color to whatever the color of your editor background is.

Change TODO item color in Visual Studio 2012 with Resharper 8

After installing Resharper 8 on Visual Studio 2012 my TODOs are now a retina-searing blue of which this screenshot does not do justice:
I've found similar questions here and here they don't seem to apply to VS2012 and/or RS8, as there is no "Resharper Todo Item" nor any other Resharper items under the Display Items for Fonts & Colors.
Just to post a possible workaround if somebody has the same behavior - apply actions from the following article. It looks oddly but works.
Close all Visual Studio instances
Open C:\Program Files (x86)\Microsoft Visual Studio {VS
version}\Common7\IDE\Extensions\extensions.configurationchanged file
Type anything there
Save the file
Open VS and check Fonts and Colors in Tools | Options | Environment
Navigate to environment settings using Visual Studio (Tools -> Options -> Environment -> Fonts and Colors) and change the colour of the TODO items in the text editor. Scroll to the item in the "Display items" list which shows as "Resharper TODO item"
A Visual Studio crash and restart later, Resharper display items are suddenly showing up under fonts and colors. I contacted Jetbrains and apparently this was a verified bug, though that link is now dead which would lead me to believe that they fixed it, but for some reason this answer is still getting upvoted so maybe not.
Maybe the next upvoter can edit this answer or provide a comment with the current state of affairs?
This is not a Win 8.x issue; I am using Windows 7 and encountered the problem when I applied Resharper 8 to VS2013. The link that Alexander posted resolved the problem for me. I did, however, have to copy the file to My Documents, make my edit there (a simple hash symbol) and then copy it over the source location.
Adding an empty line in the file extensions.configurationchanged worked for me.

How to write latex comments in visual studio 2012

I want to write comments in visual studio (2012 ultimate) that contain latex syntax.
There is some plug-in to add to visual studio that will enable me to write comment in latex and then see it as latex (e.g. pop up window when im pressing some key shortcut or moving over the comment with the mouse)?
I found that someone asked it before at:
Latex plugin for visual studio 2010
But this didn't help me.
I'm also found this:
http://visualstudiogallery.msdn.microsoft.com/e216ec81-730b-4022-8305-25c39eb1f820
But this didn't help me either (I got a message of "This extension is not installable on any currently installed products").

Microsoft Visual Studio Change Default Theme

I am finding it really hard to code using the black theme given in the visual studio 2012 IDE. Is there anyway i could get back the older grey theme or is there anyway i could make it look a bit more whiter ?
Tools -> Options -> Environment -> General -> Color Theme
or you could try to use Visual Studio 2012 Color Theme Editor , it has pre built themes too.
For Visual Studio 2015 and later versions
Tools->Options->General->ColorTheme
Change theme and Press OK.

Visual Studio 2012 colour theme format

I've found the colour theme settings for Visual Studio 2012 at HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\Themes
I can duplicate a dark output window in the light scheme by copying the relevant key so this is definitely where the color comes from (you have to restart the IDE in-between changes).
I'm wondering if anyone is familiar with the format of the binary data in these keys?
Or the Common7\IDE\CommonExtensions\ShellColors.pkgdef file that they seem to be created from?
I've tried some experimentation with changing what I guess should be the colour values with without much success.
Try this theme editor I wrote that helps you modify the built-in colors of the Dark/Light themes. Most of Visual Studio's Windowing colors are in the Environment category.
