(VB.NET UWP/WinRT) OneDrive -- List Non-Root Directory

This gets the collection of DriveItem children for a non-root DriveItem. This is the same as for getting the children for the root DriveItem, except the URL includes the path to the desired non-root DriveItem.

Note: This example requires Chilkat v9.5.0.68 or greater.
