[nvda] Re: Notepad problem

Hi,
The notepad problem is well known. Specifically, the APIs that Windows provides to fetch the text from a standard edit control do not allow to ask for text above a length of 65535 characters (this is the highest 16 bit number).
Standard edit controls were never designed to hold more than this amount of text. To be honest, any other program other than Notepad, should really not use a standard edit control if it is going to show data greater than this. 
Even notepad should really use a different control (such as richEdit).
Other screen readers get around this by falling back to display hooks or video intercept.
So until such time as NVDA has these capabilities, there is nothing that can be done about it.
However, I guess the question becomes: how would you prefer NVDA cope with this situation?
Currently it gets a bit confused and just reads what seems to be random text. would you prefer perhaps that it just said "blank"? or perhaps said some other message alerting the user it can't read this?

Dspeech suffers in the same way as notepad, by the way. This is the software I use to make mp3s with Daniel. its a basic text editor with the speech functions and save on it. I guess it probably uses the same display as Notepad.

The file does not  corrupt in reality, it just sounds like its kind of
wrapped around so bits are at the end that were near the start etc.
I know the file is OK, cos if I paste it into an email it remains fine as 
it
was before.

Hi folks, I was preparing a commented log  on Outlook express address
book
problem this morning when I noticed that some of my editing on the file 
in
notepad was screwing up. Sure enough when I edited it in WordPad things 
worked but in Notepad the actual read text seemed not to be the text I
was
editing.
Attached in is the file I was editing. it seems to have some kind of
other
file mixed up with it when I load it, but only when viewed on notepad and nvda. If I launch, foe example Hal, then what I edit and what I can cut 
and
paste and save seems fine. Itts as if nvda remembers bits of a previous 
file
I edited. Anyhow. Its very annoying. I think it needs to be a long file.
