I made some enhancement to BrowseForFolder dialog box so that I can add a New Folder to the path that is shown in the treeview. Now, I was able to add a 'New Folder' button but I cannot refresh the view so that I can see the new folder. I thought that SHChangeNotify will do the job. I believe that no one will have the answer to this. I will even accept ideas about inserting new item in the treeview.
