Hello fellow masochistic mac programmers. I've written an application that uses TextEdit records to display a list of files. The list can get rather large (60-70K) and so I've passed the notorious 32K limit. I've tried to write a switching algorithm for TERecs, and I'm about to pound my head against the wall. I can't make it smooth or get the scroll bars to line up, or anything... Has ANYONE DONE THIS? I could really use some help. Breaking the 32K barrier is now kind of important to me retaining my tenuous status as staff Mac Programmer. Thanks very much. *-----------------------------------------------------------------------------* *Charles R. (C. R.)

Oldham | Bitnet: OLDHAM@ARIZRVAX I just purchased from DataPak software a TE replacement that breaks the 32k limit. The limit now is 16 megabytes. I just received it yesterday so I haven't had time to play with it. Its called Word Solution Engine. some of its features: No 32k limit Fast editing display of large text files Multiple Font, styles, and point sizes Script manager support Quickdraw color support (don't know what that means old style color?) "UserStyles" hooks provided to customize characters. (pictures I think) Printing Support File I/O scrap support low level hooks Tabs Res version for Code resources (da's,xcmds and such) & linkable Version available for C,Pascal or Assembly developed by Gary Crandal The above was taken fron their flyer. I bought is solely for the no 32k limit. A lot of times you just need a quick and dirty editor added to an application you are writing and it needs to go beyond the 32k limit. (the Mews stack and net news reader could use this library for example). They've been trying to sell this thing to me for a while but I said it was useless to me unless it was handled more than 32k. It also was a lot more expensive before. It was $600 per application that you included it in. Now its $300 one time licensing fee. No limit to the number of applications you can include this in. There are a lot of hooks that are included in the library so you or dataPak can creat modules to expand it. One they are working on is a module for displaying pictures within the text. If you are interested call Pam B. Smith at (800) 327-6703 and tell her I told you about it on the net. I have no connection with the company except as a soon to be happy customer if this thing really works as they say. Also Martin Minow Has published his Trackedit TE replacement in MacTutor Feb and March issues. Source code is in C. You have to contact Martin if you want to include it in a Commercial application. -- ___________________________________________________________ Matthew Mora | my Mac Matt_Mora@sri.com SRI International | my unix mxmora@unix.sri.com ___________________________________________________________

I wrote a set of routines that helps surpass the 32K limit.
It was a pain in the neck, too. I would love to give
you the source, because I am full aware of the frustration
you're dealing with, but since it belongs to Apple, I can't do that.
If it was my code, I'd mail it to you in a flash...
What you might try is this:
1) Have a single TERec. This rec hold the text that the user
is currently looking at.
2) Create 2 10K buffers, one to hold the text immediately
before and immediately after the text in the TERec.
The TERec only holds 10K at a time. This allows the TE
routines to run fairly fast, since they only deal with
10K at a time.
Unfortunately, this limits pasting to 20K, but
you can't have everything...
3) As the user scrolls thru the text, you swap blocks of text
in and out of the TERec. The tricky part is adjusting the
scroll bars...I worked on it for days, but it can be done.
It can probably be done quicker, too, since I'm not an
expert programmer.
4) You have to deal with little irritations like breaking
the buffers at even lines, so half lines aren't coming
up next, and things like that.
4) When it runs, it does run NICE.
Another alternative is to get the ThinkC libraries called
Capp's Construction Set. They have routines that bypass
the 32K limit on TextEdit.
Good luck. I hope this helps.

I too would be very interested in this topic. In the times before, when I have had to fight the 32k wall, everyone has told me "it can't be done. Don't use TextEdit." Is this true ? The alternative question is: How difficult is it to do what TextEdit does without using TextEdit ? Does MSWord use TextEdit (obviously not) ? Who is willing to write a replacement for TextEdit for other programmers to use ? Let me know if I'm out of my expertise level here and these questions are inane. Eric W Sink
