The articles in these digests are taken directly from comp.sys.mac.programmer.
They are not edited; all articles included in this digest are in their original
posted form.  The only articles that are -not- included in these digests are
those which didn't receive any replies (except those that give information
rather than ask a question).  All replies to each article are concatenated
onto the original article in the order in which they were received.  Article
threads are not added to the digests until the last article added to the

Is there such a thing as a Rez or ResEdit template for 'aete' resources?
I have looked on the latest developer CD as well as the MPW C Bundle CD
and could not find one.

The newest ResEdit supplies templates for aete, etc. resources.

In a similar vein, can anyone tell me why almost NO AppleEvent aware applications
implement these resources? The ONLY application I have ever seen that does is
CEIAC. Do developers just not know about them? Are they too hard to use? (I don't
think so, since even *I* can put them in application I write.) Are they OBE?

    Some major applications (and certainly not all) that inlcude 'aete'
resources - Canvas 3.0, MicroPhone II 4.0, StuffIt Deluxe 3.0, and Excel 4.0.
I can also guarantee that you will see more than more applications including
them in the near future (ie. after the WWDC).

    I would say that this, and the fact that since most applications
aren't doing much more than the required events, they don't really need one
(YET!)

    I don't think so either, and I've been putting them in my products
for a while now.

The April CD has ResEdit 2.1.1, which does *not* know about aete resources!

I don't know if the template is in the April CD or not, anyway I am putting
a copy in ftp.apple.com. It will be in the directory /pub/appleevents.

However, anything other than the smallest 'aete' is too small to be edited
as a ResEdit template, or at least too painful to do so.

There is a HyperCard stack that let you edit the aete resource. It has been
submitted to the developer CD, I guess it would be the May issue. I have
also put it in ftp.apple.com in the same directory. And to justify why
developer should put aete resource in their application, I also put up a
sample application with aete resource on ftp, as well as a HyperCard Apple
Event XCMD stack. The XCMD stack will contains a number of XCMDs that let
you talk to an Apple Event aware application, the stack will also take
advantage of the aete resource in the application to make the conversation
as painless as possible.

Some more on aete resource.

Aete resource just tells you what kind of Apple Event support an application has.
It is mainly for information. So if an application is Apple Event aware but does
not have an aete resource, but you know what events it supports, you can always
make up an aete resource yourself and ResEdit it into the application. All of
a sudden, scripting language that understands aete resource will know how to
talk to that application through Apple Events.

For those who have access to ToolServer which is available on the ETO CD, here
is another Apple Event aware application that does not have an aete resource.
So you may want to stick in an aete resource of your own. But there is one
catch, ToolServer only supports a limited number of Apple Events, but effectively
it supports a lot of Apple Events because of the DoScript command. I have a
little hack so that every MPW command that ToolServer has access to becomes an
Apple Event server as long as the description of that MPW command is the aete
resource and the aete resource is written with certain convention. I am also
putting it up on ftp.apple.com. However you must get hold of ToolServer
separately. It can be a lot of fun using the HyperCard XCMD stack and talk to
the ToolServer using Apple Events.

I forget to mention that another Apple Event server with aete resource is the
Clipboard Magician 0.71. It is available on developer CD, it is also on
ftp.apple.com but in the directory /pub/lai.

The best place for this info is the New Inside Macintosh InterApplication
Communication chapter which is available on the May Developer CD (The Byte
Stuff).  This will eventually be published so that you can read the whole
Inside Macintosh all over again.  After all, how many times have you read

Drop a note to [e-mail].  For a very modest licensing fee,
you will become an ADB licensee!  This package includes a wide variety of wonderful
goodies, including specs for the ADB, design documents on all of Apple's ADB
peripherals, and the right to force me to register an ADB ID for you, whether
I want to or not!  This, and much, much, more, can be yours!  Operators are

     I'm considering converting some programs from MPW C++ to Objective C,
primarily to use the better libraries that Think C offers.  Are there
any tools that will assist with a conversion from MPW C++ to Objective-C?
I don't have any multiple inheritance, template, exception, MacApp, or
pointer-to-function-member problems to deal with, so Objective-C has
enough power to deal with the problem.  But some mechanical tools for
dealing with the translation would help.

Um, er, well...

THINK C is not Objective-C.  It is a C++ subset.  I know of no
tools to automate the process of converting C++ to THINK C.

I also know of no tools to automate the process of converting C++
to ObjC.

John,

You do realize that Think C is NOT Objective C, don't you?  True, it is not C++,
and it is more than ANSI C, but it is not Objective C.  Instead, Think provides
object-oriented extensions to C that look a little like C++.  Objective C is a
language (designed by a company named Stepstone) that borrows from C and
Smalltalk.  Its syntax and traditions are very different from C++, and the
object C Symantec sells in Think C.

Of course, now that Stepstone sells an Objective C compiler for the Mac, we have
even more choices to make (C++, Objective C, Think Object C, Smalltalk, Lisp,
Dylan [someday],I) for our preferred mode of expression.  Oh, well.  They say
that's what makes life interesting.

Regards,
Eric

THINK C does not use Objective C, they use Object C -- the Object Pascal
equivalent in C.  It is (almost) a C++ subset.  Objective C is the language
developed by Brad Cox and StepStone which is essentially C with embedded
SmallTalk for OO work.  StepStone has an Objective C preprocessor to the
MPW C compiler for $99.  It comes with their Software ICPak (component
library).

If you don't use "friend" or overloading, you probably don't have much to
convert.  If you do, you're going to need to do it manually, anyway.

Objective-C only works with MPW 3.2 at the moment.  Stepstone said they were
interested in getting it to work with THINK C, but I wouldn't hold your breath
waiting for that.

Although I like the THINK environment better, the benefits of programming in
Objective-C outweigh the disadvantages of MPW (lack of speed, cryptic, to name
a couple).

What is the current status of Objective C for the Macintosh?

What libraries does it come with?

Does it have any support for MacApp?

Any other info?

It comes with Stepstone's ICPak-101 which is a set of 20 classes that support
basic data structures (e.g. lists, stacks, arrays).

Not that I am aware of.

> Any other info?

I've been programming the NeXT for over 3 years and am quite pleased that I can
finally use my favorite language on the Mac.  I have been using Objective-C
with MPW for over a month now (it was just released...), and am happy to report
that my only gripe is that it doesn't support "\p" style Pascal string
constants (you have to put the length byte in yourself).  Outside of that, it
has proven to be quite useful and has jumped to the top of my list of favorite
Mac Languages.  I haven't completed a project with it yet, so it may be too
early to tell - but everything is cruising along so far.

I don't know if Stepstone is still offering the $99 price, but if they are and
you have MPW C 3.2, it's a steal of a deal.

Disclaimer: I am not affiliated with Stepstone except as a happy customer.

It DOES come with the ICPak101, but the ICPak201 is not yet available for the
Mac.  Stepstone is still selling Obj-C for the Mac for $99 (a steal!).

Just a happy Objective-C user,

Not according to the manual. I got my copy today from the engineering
library, and if I have enough time I will stress-test the package for
a week or so. Lack of an application framework means I have to write
one, sigh.

Organization: University of Rochester - Rochester, New York

Thanks to all who provided informative (and some not) possible
solutions for my attempts to get the SuperDrive to read MFM
diskettes from a keyboard sampler (EPS).  Unfortunately, there
are new problems.

The .Sony driver knows this is not a GCR diskette, so it attempt
to read the diskette as if it were a 720K MFM (IBM) diskette.
Unfortunately, the diskette is sectored 0-9, not 1-9 as IBM
diskettes, so PBRead calls always skip sector 0.

I suspect this would mean the only solution left is in tweaking the
actual driver.  Any ideas?

Yes, I don't suggest you tweak the driver.  The driver itself will only deal
with the four disk formats it knows about.  It doesn't have tables of format
information that it references, and thus that you could change on the fly.

Second point: on the IIfx and Quadra 900, the entire floppy system is run by
a separate processor, so you won't have any access to the hardware or to the
code that runs the show.  Also, on the portable Macs, power management stuff
is integrated into the floppy driver, so playing inside the driver could
cause problems elsewhere.

Third point: Apple will, no doubt, get around to changing their floppy
hardware to improve performace, support new formats, etc.  When this happens,
any inside tweaks will no longer work.

Of course (since I missed the original post), if you just need to get this
working on your system at home, compatibility is not quite the issue.  If
so, ignore my ranting...

Hi all,

Can someone tell me where I can find more info on Bento, Apple's proposal for
a compound document storage format?

I hope Apple use "Obento" instead of "Bento", which is more polite :)

You should probably email Richard Moore ([e-mail]) and
ask for info.

      I'm considering converting a program from MPW C++ to Think C.
How hard a job is this, and are there any mechanical aids for so doing?

No tools that I know about, the most ugly thing would be to convert
nice constructors to simple ones, but then again if the code is MacApp
you don't have this problem. Another silly limitation is the lack of
any more complex functionality inside a constructor (like creating
other objects). I guess downgrading is fine, but sooner or later you
need to upgrade again (grin).

Subject: Problems Updating MENU Resource
Date: 14 May 92 15:52:26 GMT
Organization: University of California, Santa Barbara

I'm having some problems saving changes made to a MENU resource at run-time.
Essentially, I'm allowing the user to add and delete items from a pop-up menu
and I want to save those changes to disk when the program quits.

The way I was doing this was by calling ChangedResource() on the MenuHandle
for the pop-up menu.  The problem with this was that when I call GetMenu() the
next time the program runs, the menu is not displayed.  If I replace the MENU
resource, the program will work again.  It appears that the MENU resource is
getting corrupted somehow.

I am using THINK C 5.0.1.  Any help would be GREATLY appreciated.  Please reply
via e-mail, unless you believe that other netters could benefit from your
response.  Thanks in advance.

The menu manager puts something in the menuProc field.  Assuming you have
a MenuHandle in mh, you want something like:

    Handle savedProcId = (*mh)->menuProc;
    (*mh)->menuProc = nil;
    ChangedResource(mh);
    WriteResource(mh);
    (*mh)->menuProc = savedProcId;

>From page I-364 of Inside Mac:

"The four bytes beginning with the resource ID of the menu definition procedure
serve as a placeholder for the handle to the procedure: When GetMenu is called
to read the menu from the resource file, it also reads in the menu definition
procedure if necessary, and replaces these four bytes with a handle to the
procedure."

When you save out the MENU resource, you are writing out a version that has a
handle to the MDEF, instead of the resource ID of the MDEF, which is what you
want. I guess it would go like this:

mdefHandle = (**myMenu).menuProc;
(**myMenu).menuProc = (Handle) (mdefID << 16);  // mdefID will probably be zero
ChangedResource(myMenu);
WriteResource(myMenu);
(**myMenu).menuProc = mdefHandle;

Hello News readers,

Is it possible to program a Mac II (or better) with stereo sound output?
If it is possible, then I would like to play a sound to either
the left or right channel as I need.  How can I direct the sound to
one channel or another?

Thanks in advance.

Yes, but no programming is necessary.  Just call SndPlay on a snd resource
that contains a stereo sound header, or call bufferCmd yourself pointing
at this sound header.

No can do with the current version of the Sound Manager.  The stereo
buffer will contain the left/right information.  If the sound is in the
left channel of the sound header then it plays in the left speaker.  You
cannot "pan" a sound within the stereo field.  It's a feature we're adding
to the next version of the Sound Manager.

Jim, can't you open two channels, one with initChanLeft and one with
initChanRight, and send bufferCmds to either or both?

Ooooooh, you shouldn't tease us like this!  :-)
