  I'm working on a WPF MVVM application and I've got a TextBox on my view that is bound to a DateTime property on the ViewModel.

• Is there a simple way to make lists behave as files (with ftplib)

  - by Brent.Longborough

  I'd like to use ftplib to upload program-generated data as lists. The nearest method I can see for doing this is ftp.storlines, but this requires a file object with a readlines() method. Obviously I could create a file, but this seems like overkill as the data isn't persistent. Is there…
