Does someone have example code snippets how to walk the shell namespace in Python? I'm lost in all these pidls and folders.
The code below uses the pywin32 functions to walk. Because there's all sorts of things which can happen, I've implemented a v. broad except: clause just to keep things going. Since this uses the pywin32 wrappers, it's hiding a certain amount of the PIDL/SHITEM stuff, but the functions are pretty much the underlying win32 ones. One thing I don't know how to do without using comtypes is to find the parent. the SHBindToParent function would be the way to go but it's not exposed and I don't have the energy to set up all the comtypes boilerplate to make it happen: I'm sure you can manage, though :) http://msdn.microsoft.com/en-us/library/bb762114%28VS.85%29.aspx The upside of the pywin32 wrappers (lots of stuff done for you) is also its downside (you can't take complete control if you need to). <code> import os, sys import pythoncom from win32com.shell import shell, shellcon def walk (root=None, parent=None): try: if root is None: root_folder = shell.SHGetDesktopFolder () root_name = root_folder.GetDisplayNameOf ([], shellcon.SHGDN_NORMAL) else: root_folder = parent.BindToObject (root, None, shell.IID_IShellFolder) root_name = parent.GetDisplayNameOf (root, shellcon.SHGDN_NORMAL) folders = list (root_folder.EnumObjects (None, shellcon.SHCONTF_FOLDERS)) items = list (root_folder.EnumObjects (None, shellcon.SHCONTF_NONFOLDERS)) yield ( root_name, [root_folder.GetDisplayNameOf (f, shellcon.SHGDN_NORMAL) for f in folders], [root_folder.GetDisplayNameOf (i, shellcon.SHGDN_NORMAL) for i in items] ) for folder in folders: for info in walk (folder, root_folder): yield info except pythoncom.com_error: pass if __name__ == '__main__': for root, folders, items in walk (): print root, folders, items </code> TJG _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
