FTP Treeview Control Browser Using API

I am wanting to develop a Browser for FTP files & folders using a Treeview made by using API. I have been able to get the first levels Files/folders to show up but not Child Nodes. Is there already an API function that shows FTP files and Folders? For example, can a person use the SHGetFolderLocation routine list here to show FTP Files/Folders instead of local drive Files/Folders.

P.S. I am currently using a standard Listbox to show FTP files & Folders, but this only shows one level at a time compared to multiple levels that a Treeview control could show.

Thanks in advance for any useful help.
