Created May 13, 2016 01:28
Class that can be used to retrieve the currently selected text (if any) from an active control in the active window. It does this by trying several methods internally (UIAutomation, API calls using SendMessage + WM_GETTEXT, Clipboard). Be sure to reference UIAutomationClient and UIAutomationTypes!
