title: Sharing strings across classes
body: <p>I have a combobox that lists hard drives, binded to that for selected value is a string called currentdrive which when selected value on the box changes, enumerates selected hard drive, filling a listbox with image files, but I have a second listbox that needs to also know the current hard drive, this listbox won't be displaying images, I intend it to display metadata about the images but I need this box to know what the selected harddrive is before it can display metadata. Because metadata etc will be in its own class how can I access the currentdrive string without, repeating the currentdrive string, I want the metadata class to be able to share that functionality.</p>
