Toggling Edit Control Word Wrap

Question:
I have an OWL application in C++. I need to be able to switch in run-time between wordwrap and no-wordwrap text in the Editor window. How can I do this?

Answer:
This is a real pain if you are using the Windows Edit control. Because word-wrapping cannot be changed once an edit control is created, you must actually destroy the edit control and create a new one.

When you use a program like Windows Notepad, this doesn't seem to be the case. But you'll notice that when you toggle word wrapping in Notepad, the caret position is automatically positioned at the start of the text. This is because Notepad saves the text in memory, destroys the edit control, creates a new one, and fills it back up with the saved text. Definitely seems like Microsoft should have made this a little easier.
