Hi all,

I am currently developing a shell extension, which introduces some new
columns for Windows Explorer's detail view.

Everything works fine, but how can I programmatically (via registry
settings or the like) activate these columns, or determine whether the
columns are visable due to the user's settings? Currently, the user has
to switch on the columns of my Extension manually, which I want to make
a little bit more user-friendly.

Any help is appreciated,
Ron
