Physical unit edit classes
COXPhysicalEdit, COXTimeEdit, COXAngleEdit, COXLengthEdit, and COXTempEdit

The COXTimeEdit, COXAngleEdit, COXLengthEdit, and COXTempEdit classes are all derived from COXPhysicalEdit which is derived from CEdit .
Have a look at the new Page Setup dialog boxes in Windows95 and compare them to the margins setup property page in the Microsoft office applications (or others). The fundamental difference is that in the office applications you can enter the values for margins as a physical value (numerical value and a physical unit) whereas in the standard dialog you cannot supply a unit.
The COXTimeEdit, COXAngelEdit, COXLengthEdit, and COXTempEdit classes allow you to implement the same type of controls in your own application : for time (duration), angle, length, and temperature. No need any more to define a fixed unit at design time for your dialog boxes or property pages.

Features:
•	Adds physical units to numerical input in edit controls. 
•	Build in functions for conversions between physical units. 
•	Functions for setting and retrieving physical values in desired units. 
•	No need for SetWindowText() and GetWindowText() any more. 
•	Extended COXPhysicalEdit base class which can be easily derived to implement other physical properties (area, speed etc.)
