Description
Is called to raise the OnChangeTracking event on any change made to the text of the memo.
The OnChangeTracking event provides the first opportunity to respond to modifications that the user makes by typing into the memo control.
The text of the memo is already updated and reflects any changes when DoChangeTracking is called.
The difference between DoChangeTracking and DoChange is that DoChangeTracking is called at each modification of text in the memo control.
Note: DoChangeTracking is not called in case of changes made only to text representation characteristics (for example, when changing TextAlign).
