Tree Control - Getting a Folder

I am using the Tree Control. It needs the name of folder to explore and fill in the tree. I tried using the common dialog - return open option. This allow me to select a file but not a folder. So if I select a folder with subfolders and not files then I cannot return the path to the tree control.

How do I get the folder? Is there an extension that returns the folder?

File object

That was my first guess also, but it requires me to pick a file and not a folder. I want to just pick a folder.

The File object has a directory selector.

Yes I am an idiot. I was confusing the common dialog with the file object. Thanks works fine.
