It seems you are reading a very old book, the only reference I find to "reseditor" is a sample application from .Net 1.1 SDK (VB 2003). Since VB 2005 resources and editor is included in the IDE. In VB 2010 you can find the default resources from project properties, Resources page. (or Solution Explorer, show all files, navigate My Project, open Resources.resx) The resources you add here is accessible in code with the My.Resources object, where each resource is exposed as a strongly typed property.
You can also add a new (text) file with .resx extension to project to create a new custom resource set, opening this will give you the same built in resource editor. Also for this you can generate code accessors by changing the Access Modifier in editor, it will then appear as a 'subfolder' under the My.Resources object.
