Right-margin marks in VS2010 text editors

In VS2008, you could enable right-margin marks by creating a string registry entry named Guides under HKCU\Software\Microsoft\VisualStudio\9.0\Text Editor. It also worked with the express editions: replace Visua开发者_JAVA百科lStudio with VCExpress or VCSExpress.

I've just tried (and failed) to set them up in VC++2010 Express and VC#2010 Express; does anyone know if they're still supported?

The first hit is 'editor guidelines', an extension that reads the same registry keys as before. I think there are other extensions in the gallery for it too, maybe.

Here's the link & description of the extension:

Visual Assist X also has a feature for this, under

Visual Assist X Options -> Advanced -> Display -> Display indicator after column ....
