This question has actually nothing to do with Think-C, strictly speaking,
or Mac interface. Anyway, do you have the source of some Kalman filters
for real-time filtering?
Of course it would be nice if it's already in Ansi C, or, better, if it
uses somehow TCL.
Anyway any information will be very much appreciated.
Thank you

Hey there,
I am planning on writing a medium size database program (50-75 thousand
records) that needs to be able to run under the Mac OS and DOS. I need to be
able to easily add my own functions in C & decent control over the user
interface.
What experiences have you fine folks had. Should I bother using a database
program at all, or just write the thing in C++, porting the necessary
objects.
Also, I would prefer that the database program be compiled rather than
interpretted. So I am basically writing my own program on top of a database
shell.

BTW, this is being cross-posted to Mac-L & think-c so sorry for any
repetitions.

thanx,

I am pretty proficient at C, and have very limited experience with database
programs. I am thinking of having the majority done by June, with fair
amount of time to work on it (I'm still in school). I guess I am really
lookng for a good library to help me implement a relational database (some
good books on the subject would be useful as well :-). How easily do FoxBase
& Omnis 5 let you create your own application on their database formats?

Hi to all those who asked me to forward what info my request for TCL
source code and database libraries generates. I most certainly will
pass anything I get on.

Come on guys! to those of you who assume that we all know as much as
you do. I'm a novice in this domain, as are many of those who have
asked me to share your pearls of wisdom.

I'm a 4D (ACI/ACIUS) developer who's decided that it's not on to
lumber prospective users of my products with the US$200 a runtime
engine for databases created in such development environments as 4D,
Omnis, and FoxPro costs. Actually, the product I'm working on now is
intended to make life easier for people doing almost any sort
research, and because I'm currently bankrupt I propose to give it
away, initially anyway.

I want to store information pertaining to literature searches, and to
personal communications (such as this). This will only ever be a
single user product. It is unlikely ever to contain more that 1000
records, with the average capacity requirement likely to be less than
half that.

I have the (TCL) user interface finished, and am happy to send a copy
of this shell to anyone who would like to get a better idea of what
I'm on about - presumably in order that they may then be better
placed to offer advice, or some other sort of assistance. I finished
the equivalent 4D product long ago. I am now treating it as a
prototype. This too is available (free, of course) to anyone who is
prepared to advise me, and who has a 4D 2.1 or better runtime engine
or developer kit.

There seem to be a number of us with quite similar requirements, so
please don't hold out on us.

Thanks in advance! - and in the most grovelling manner you can
imagine!

Jim

PS  Special thanks to Jeff Garner for his information on the ctree
Plus library from Faircom. Faircom sent me an almost illegible 8 page
fax containing a lot of detail that was way over my head. (They can't
be expected to know what a dummy I am.) I suspect that if you were to
describe how you use ctree one or more of our group might benefit
enormously.

The class your looking for is called CPEditText.  I have it on my mac

Subject: TE32K, TextEdit replacement package
Date:     Sun, 3 Jan 1993 11:14:40 -0500
From: Roy Wood <[e-mail]>

Here's the TE32K package, a replacement for the standard TextEdit routines.
The major difference between TE32K and TextEdit is that TE32K allows for
manipulation of text records LARGER than 32K.

The package consists of C source code and minimal documentation.  Generally,
if you can use TextEdit, you already know how to use TE32K.  The package is
designed to be a drop-in replacement for TextEdit, so basically no changes
to your existing code are necessary.  (Liar! You have to change all your calls
from TE routines to TE32K routines! Okay, but that's just a matter of a global
search and replace-- the algorithmic stuff doesn't have to be changed)

TE32K is provided more-or-less free to everyone, though I ask that if you
use it in a piece of software you sell, then please donate $1 to the World
Wildlif Fund.

Bugs in the source are provided at no extra charge, of course :)

Hello folks,
I use TE to display text and  I use a font which includes also the
control characters 0x00 - 0x1f, i.e. small cr for 0x13, small nl for 0x0A etc.
However, I do not want to display them.
On System 7 it's OK, but on sys 6, TE displays a small cr
at the end of every line.
So it seems to me that there is some (undocumented?) "show invisbles" flag
which is set by default to false on sys 7 and to true on sys 6. Does anybody
know more about it?
What should I do to cure the problem? I edited the cr character of the font
to "spcace" but it does not help - now it displays an empty rectangle.
How can I remove the control characters from the font so that it starts from
0x20 ?

Lines: 30
Date: 8 Feb 93 20:21:13 GMT

I am writing a set of code resources in ThinkC and have a question regarding
saving registers and system globals.
My situation: MacProlog includes hooks to use CODE resources compiled with
Think C or MPW C. MacProlog opens the resource file and passes control and
function parameters to the code resource. Since MacProlog doesn't provide
the window and image manipulation tools I need, I'm using Think C. So far
everything is working, but I hate to keep going only to find out that I'll
run into trouble later. My C code looks like this:
#include <SetUPA4.h>
main(x,y,z)
    long x;
    long y;
    long z;
    {
    RememberA0();
    SetUpA4();
// ... open windows and files, use CopyBits, Lock handles, update windows
// ... and lots more
    RestoreA4();
    }
I have noticed that A4 isn't really mentioned in Inside Macintosh or Think
Reference, but A5 is. Has think just written these A4 routines to make
life easier, or should I be saving and restoring the A5 registers too or
instead. Essentially all of the info passed to and from the Code rsrcs
is passed in the function call. But I want to make sure that all of the
windows and data structures I create inside the code resource don't get
overwritten by the OS or memory manager.
Again everything seems to work just fine so..If it ain't broke...

 Thanks 1E6, Roy. This helps me a lot!!
 I'm going to add multi-byte character support to it. (Or minimal
support of Script Mgr, that is what I need to use it with Kanji.)
 Sometime later, I'm willing that I post the extended one with
rising the donation to $2. :-)

Message-ID: <[e-mail]>

Hey all,

Does anyone know if hypercard interprets events solely
in the order they are in the queue, or does
it give certain types of events (like mouse clicks) higher
priority than others (like apple events)?

The reason I ask is such:  I have a program that send scripts to HC
in a 'misc'/'dosc' apple event.  The problem is, that if my app sends an
AE to HC, and the user quickly switches to HC and clicks a few buttons, the button
clicks may be interpreted before the AE.

I thought maybe the event manager prioritizes events, but could find no such
text in IM6.

Is the order of event interpretation possibly the problem?
Or have I sent something wrong?

BTW, i am sending the event with the kHighPriority flag, (which puts it at front of
queue), not the kNormalPriority flag (which puts it a end of event queue).

FYI:  HC2.1, mac IIci, 8megs RAM, few extensions

If you could reply by email, I would be thankful.  I will post summary to group
if there is interest or I find something interesting.

I wrote sometimes a code that shows nicely in a modal dialog
an explicit text for all registred xxxErr.
From the dialog it is possible to "ExitToShell", enter the Debugger
or try to continue (safely or not).
The strings are those from Apple as "furnished" in the DA System Errors
(System Errors 3.1)

    Put Think Reference 2.0 in the background for a while.  I'm not sure
how long, but 15-20 minutes is usually sufficient.  When you bring it to
the front again, watch the guy closely.  I would tell you what he does
but its more fun to find out yourself.

    Somebody at Symantec is evil to put this in there with a timer on
it!

RCS, in its latest incarnation, is part fo the GNU software
distribution.  This means that if you wanted to, you could port it
(you'd also need GNU diff) to the Mac (despite the FSF's reluctance to
support Apple in any way, shape or form).

It's been a project that I've wanted to do but probably won't have
time for until at least this fall.  So, the real question is, is
anyone else up to it?

If anyone else does it, how about modifying the actual code as little
as possible?  I imagine you could just rewrite main() and add all of
the event loop stuff and menus, and throw all of the source files into
one project and it'd probably all work.  Oh, and you'd have to write
an interface between rcs and diff (probably the easiest way is just to
imbed diff in rcs; you could then also add menu options for diff as
well).

Oh, there's also a commercial version of SCCS for the Mac; I've never
used it and I don't know if it's any good.

Lines: 78

Hi,

I apologize for the vague subject line but I couldn't think of anything
better.  I have a question about the cursor changeing when an alias of
a running application is double-clicked.

Attached is the source for a very simple program (a gutted version of an
EventLoop).  I compile and build an application, and everything is
fine when it's run (it just sits there like it should).

I can run the application, switch to the finder, and double-click on the
application's icon, the cursor momentarily changes from an arrow to a clock
and then into an arrow as when the application is in the foreground -- no
problems.

However, if I create an alias to the application, run the application,
switch to the finder and double-clike on the ALIAS's icon, the cursor
changes to the clock, the application comes into the foreground, but the
clock cursor doesn't change back to an arrow.

I tried this with "commercial" applications, and the cursor goes from arrow
to clock to arrow just fine.

What's going on here?  Does my application have to keep track of when it's
brought to the foreground (and how do I do this)?

I'd appreciate any help.  Thanks.

Hi,

I've just started programming on the Mac, and wanted to do some simple
animation.  I thought I'd start with a simple bouncing circle.  The problem I'm
having is that its _very_ slow.  I have tried drawing directly to the window,
as well as using an offscreen grafPort and then using CopyBits to copy
the bitmap to the window.  (Drawing directly to the window was faster).  I've
seen some other programs that can perform animation much faster.  Is there some
trick that I'm missing?

Any help would be appriciated.

How big is your sprite that your are drawing? How are you drawing the circle?

Please explain the steps you are doing in your animation and we can tell
you how to improve it. I get excellent speed using offsceen buffers.

Things to consider:

Copy rectangular areas
Make sure depths match
Copy only data that you need (minimize or eliminate clipping)
Align bitmaps/pixmaps
Read tech note "of time and space and copybits)

This is done by one of the standard initializaion calls; I think it's
the call to initialize QuickDraw.

Yes, you do need to do this yourself.

The general answer is to set the cursor whenever you get an event to
activate a window.  This should work under System 6 as well a System
7.  Note that in the (now outdated) System 6 without MultiFinder, you
should be doing this anyways so you don't get stuck with a DA's
cursor.  So, the problem has been around even before MultiFinder.

For a MultiFiner-only (including System 7) application, you should
keep track of suspend and resume events, and generate your own
internal window activation events, but the above will work if you
don't have the 'accept suspend/resume events' flag set.

Unfortunately their knowledge of the colour stuff doesn't extend to various
companies' video card info.  I know.  I'm one of the DepthGauge developers.
(I did the low level patching stuff - Dan Segel handled much of the
interface stuff).

It's an interesting idea....maybe if we can get enough info from the
different hardware developers we could look into adding the functionality.

Unfortunately, neither Dan nor I feels particularly motivated to put in
more hours on DepthGauge (though we will fix bugs that people report, we
don't have any plans for future upgrades).  When we add up the amount of
shareware payments we received, and figure in the number of hours we spent,
we earned less than $1.00 per hour.  A lot less.

But we will add the idea to our list of possible upgrades.

Howdy,

Several people responded with Reference Link.  I am looking for the other,
earlier patcher.  I just got THINK Ref 2.0 and would like to start using
Reference Link.  As such, I would like to remove the earlier patch from my
THINK C editor.

That earlier patch also allowed for balanced parantheses and other goodies.
 It was a direct patch of the editor, not an extension.

Recently I upgraded to Think C 5.04 after using Think C 4.0 for some time.
I just compiled my first program and I got the error.

"last argument to function GetNewWindow does not match prototype"
for the following line of code.

WindowInit()
{
    gGrammarWindow = GetNewWindow(128,NIL_POINTER,MOVE_TO_FRONT);
    ...
    ...
}

NIL_POINTER is defined as 0 and MOVE_TO_FRONT is defined as -1.
gGrammarWindow is declared as a WindowPtr.

Last time I checked GetNewWindow took three integer arguements. So this is
confusing.
Anyone out there know what could be wrong here?

This might be a newbie question, but I can't find it in a FAQ or after RTFM...

I've attempted three times now to rebuild a pre-existing project by starting
a new project, and then adding the source files and libraries back in the same
order as the original.  I also make sure the segments match.

Each time I've tried this, I can't compile all of the source files.  I get the
error message "invalid redeclaration" and a function comes up, highlighted, in
one of the source files.  If I attempt to compile further source files
individually, I'll get a couple more of the same error.

There is no redeclaration.  Not only did all of the source compile properly
already in the previous project, but I've run a search on all of the files to
see if another declaration for each specific function exists -- it does not.

Any idea what would make Think C (5.04) give this error?  A friend where I work
had this happen too under the same circumstances; ie. rebuilding a duplicate of
an existing project.

My goal is to take the existing source and modify parts of it to do what I
want, but this problem is keeping me from leaving the starting gate.  Thanks
for any pointers...

One curious fact that I've observed,
which could possibly be relevant.
Sometimes a project seems to find a header file
that is neither in the Think C tree nor in the project tree.
Eg I couldn't compile the Starter project
because it found an oops.h
from a "Useful code" folder containing some old stuff from Symantec --
as opposed to the correct oops.h in the Think C tree.

(I'm still assuming that this was an error on my part,
though I can't see what it was.
The "Useful code" folder was outside both trees.)

The "problem" is that ThinkC will follow alias-folders, when searching for
files.  Try this:  place an alias of the #includes folder IN your project
folder.  You'll wind up in an infinite loop as ThinkC searches for the file.
In my opinion, this is a bug.

Since when? Last I was aware, THINK C does -not- follow aliases. It would
be nice if it -did-, though, in some cases.

Invalid Redeclaration errors which appear when creating a new project
from scratch usually indicate that there's an #include or a #define in
the "Prefix" section of the project settings for the old project
document that needs to be brought across into the new project. In
this regard, the Prefix can be a bit inconvenient. One possible
handy feature for a future THINK C might be to support a "project.prfx"
text file in the same folder as the project....

I'm *quite* certain that the problem happened to me as described.
I was using either 5.0.1 or 5.0.2 at the time.

I'll try to duplicate it again...

BTW, since I'm wasting bandwidth here, I might as well ask a question.
What's the best way to edit 'aete' resources without resorting to
commercial utilities?  I can't ever get ResEdit 2.1.1 to accept the
various versions of the 'aete' template I have.  (too many fields or
something to that effect).

Also:  I've developed a C Interface kit for the new Public Address BBS
system for the Mac.  Anyone interested in writing modules for the new
system (Ascii/Ansi/GUI), feel free to contact me.

Subject: Macintosh/TI NuBus Question
Message-ID: <[e-mail]>
Newsgroups: fa.think-c
Lines: 24
Date: 27 Feb 93 19:22:53 GMT

BACKGROUND:
Apple's Designing Cards and Drivers publication, as well as the IEEE's NuBus
publication, both show that the /TM1, /TM0, /AD1, and /AD0 signals support
8-bit byte and 32-bit word operations at address 0 (modulo 4).

PROBLEM:
With our 32-bit 1196-compatible Memory PCB, we need to enable only the
appropriate 16-bit RAM bank during 16-bit NuBus write operations. With the
current implementation, we don't see a way of preventing an address 0 modulo 4
write operation from accessing the entire 32-bits of RAM (and erroneously
writing an extra 16-bits).  Motorola's /SIZ1 and SIZ0 signals provide this
capability on the local uP bus.

QUESTION:
Is there a NuBus method of performing a 16-bit half-word (doublet) operation
at address 0 (modulo 4, /AD1, and /AD0 both H )? If so, how is it done and
what are the control signal encodings?

Thanks in advance for any and all answers/suggestions - if you're aware of a
better place to post this message question, please let me know.

Yep, no folder alias resolution in THINK C 5.0. Sorry.

My vote is for forgetting to turn on the Require prototypes option.
If you have full ANSI prototypes in your headers, but have old style
definition in your source files, then you'll get an "invalid
redeclaration" error when THINK C sees the definition(*). Turning on
Require prototypes turns off this (ANSI C) restriction.

(*) Actually this only occurs when declaring functions that use narrow
types. Functions that use widened types for all parameters will not
see this error. But hey, we all use Require prototypes at all times
anyway, right? :)

Well, you can always add a #include "project.prfx" statement to your
prefix, and click on the "copy >>" button to make it the defualt for
all new projects. Although you'll have to customize it if you put more
than one project in a single folder...

Title says it all.

Thanks.
