RichEdit: referencing the ‘rft’ property resets undo queue
Posted: Monday, May 22, 2006 8:12 AM (EST)

We've not been able to reproduce this problem in versions 4.0.03 to 6.0.10. In which version(s) are you seeing this problem? And what is the operating system?

I tested this on two different Windows XP SP1 machines with APL+Win Version 4, 5 and 5.2 and I get always the same result that referencing the rtf property will clear the undo queue.

I‘m using the German Windows XP version, may this is the difference here. I suggest not to investigate this further as it’s a minor issue.

FYI:
This is a bug of the native Win32 RichEdit 3.0 control. This issue is fixed in RichEdit 4.0.

Actually, what I found out is that also newer Rich Edit 3.0 dll have the undo queue bug fixed.

On Windows XP Riched20.dll with version numbers larger 5.30.23.1215 (SP1) or 5.30.23.1216 (SP2) should work.
