Rich Edit Version 2.0
[This is preliminary documentation and subject to change.]
Rich edit version 2.0 includes several new features, such as support for Unicode and Far Eastern languages, multilevel Undo, and numerous user interface enhancements.
With a few exceptions, rich edit 2.0 uses the same Win32 functions, structures, and messages as rich edit 1.0. The differences are listed following.
The name of the rich edit 1.0 window class is "RichEdit". Rich edit 2.0 has both ANSI and Unicode window classes, "RichEdit20A" and "RichEdit20W", respectively To specify the appropriate rich edit window class, use the RICHEDIT_CLASS constant, which the RICHEDIT.H file defines depending on the definition of the UNICODE compile flag.
In rich edit version 2.0, if you create a Unicode rich edit control, specify only Unicode data in any window messages sent to the control. Similarly, if you create an ANSI rich edit control, send only ANSI or DBCS data. You can use the IsWindowUnicode function to determine whether a rich edit control is Unicode.
