Add guide to Visual Studio Editor:

I found a way to do that by adding a registry entry. If there is any easy way or setting available in visual Studio, I am definitely not aware of that.

Step by Step Procedure:

Step  1. Go to RUN window and enter REGEDIT and press enter.

Step 2. Choose

COMPUTER à HKEY_CURRENT_USER à Software àMicrosoftàVisualStudioà9.0àText Editor.

Step 3. Then right click on Right pane and choose NEW à StringValue

Step  4. Name the new String as Guides and String value as RGB(100,100,100,100), 80. (Edit window is opened by double clicking on Guides row).

Step 5. Now Reopen the visual Studio and notify the vertical line at 80 Columns. ( You can specify the different value for color and column  too(i.e RGB(x,y,z), col).

Thanx.
