Let me clarify my point. The present scheme is not sufficient for
most people.

I can't believe that 'WDBN' or 'DFBC' are really meaningful to people.
Who would want to carry around in their skull a list of these 4 letter
codes.

The scheme we have, has been lazily adopted from the OS's internal
mechanism for tracking file ownership and type. I don't believe it
was ever Apple's intention to have people (other than programmers)
aware of these codes.

Because Apple and us programmers were, in hindsight, lazy about this,
the scheme has been pushed onto our customers. Now they have to contend
with cryptic 4 letter codes to identify documents when the Finder
is unable to do so.

One possible way to begin dealing with this in the future is to put
written descriptions of the file in an Apple specified resource within
the file's resource fork. (i.e. "Word 4.0 Document", or "MicroPhone II
v4.0 Document") This would give a future version of the Finder
a last ditch method of identifying the document type when the owning
application can't be found. The Finder would present this info to
the user so that they may determine what to do with the file.

Let the current scheme stand, we have only DOS-like schemes to fall back
to at present, but let's please think about making the situation easier
for the rest of us.

Uh.  Read Inside Mac Volume VI - there are two STR resources you can stuff
into a document. Id -16396 is the name of the application that created the
doc, and -16397 is a custom message to display if the app is not found.  See
pages 9-21,9-22.

The future is today!

This scheme already exists under system 7. If you include a STR
resource, id -16396, this is taken to be the name of the
application for the "this doc couldn't be opened" Finder alert.
You can also customise the alert completely.

That way has already been defined for system 7. It's in Inside Mac.

The current finder (Sys7) already supports that.  You can put a resource
in any file that identifies the app that created it.  You can also put
a custom icon, ballon help, etc, that the finder will make use of.

Not only can you put in a special system-7 identifier of a file type,
but some programs (such as Dreams) identify their files with something
which started in system 6: use the vers id 2 resource. That way when you
'get info', you see something like
    house layout
    Dreams family version 1.1
Which looks somewhat weird, but it's better than nothing.

Good!  I had a feeling this was the case, but since I don't keep a
set of Inside Mac volumes here at work, I couldn't verify my hunch.

Thanks for spotting this.

Now, if people besides Apple were to start using this...    :-)

Inside Mac Volume III page 9 says: "Note: Signatures and file types may be
strange, unreadble combinations of characters; they're never seen by end
users of Macintosh."

Inside Mac Volume VI page 2-13 says: "In particular, don't use file type
names to refer to Finder documents that users see. Call documents by the
terms that appear in the Kind column in Finder windows."

Inside Mac Volume VI page 9-8 says: "...Since the system software never
displays signatures and file types to users, signatures and file types
can consist of character combinations that are incomprehensible to
anyone but you."

I would advise ignoring the last part and carefully picking your signatures
and file types to be as clear as possible. Macintosh PC Exchange displays
file types to users. (Although it also displays the matching icon for the
file type, that was deemed as not enough information to distinguish between
the differing file types you may be mapping MS-DOS files to.

Wow, someone actually mentioned Dreams?!  Chuck Soper wanted to do this to
identify all the files that come with Dreams, and I told him how to do it.
We disagreed on whether it should be saved in files, but he wrote all the
i/o code...

It's good to hear that this is useful for something.  It would look a
little less weird if it said something like "Dreams version 1.1 document".

Speaking of the draft Inside Mac chapters on the Dev.CD, has anyone
successfully printed them to a LaserWriter?

I've been trying to print the Apple Event Manager chapter from the
Collaborative Computing book, and it goes along just fine until it
hits a page with a figure. Then PrintMonitor just sits there forever
saying "processing job," and the LaserWriter's green light just keeps
flashing. If I cancel the job, PrintMonitor goes away, but the Laser-
Writer never wakes up--I have to power it down and back up again.

If I start printing again from the page that it freaked on, I can some-
times get it to work, but I have encountered pages that won't print
ever (page 2-14 of Collaborative Computing, for example).

I'm printing from a Macintosh II with 5 MB RAM running System 7.0.1* to
a LaserWriter II NT. Any hints on what I can try? I thought about playing
with the Viewer's memory partition, but since it's getting the stuff out
to the printer driver, I didn't think that would have much effect. The
problem seems to be in PrintMonitor, the LaserWriter driver, or the Laser-
Writer (hardware) itself.

So is this a bug or a feature? (Apple's way of ensuring that we buy the
real book when it comes out. :-)

Subject: THINK P - Making an App Drag-n-Drop'able

In THINK Pascal, how do you make an app capable of opening a file that
is dragged onto it (or, for that matter, an owned file that is double-
clicked)? I would assume that I'll need to have some sort of check
before the main event loop, but how do you tell the program that it
needs to open a file at launch? Or, at the least, where could I find
the info?

Thanks in advance.

Read anything you can on FREF resources in Inside Mac. Volume VI, chapter 9 is a
good place to start, especially page 9-15 and thereabouts.

Keith, I think he's missing the code to open the files since he mentions
the owned file opening also.

Under system 6 you use the CountAppFiles/Getappfiles routines. In system
7, you want to support the core apple events to get this to work. But the
old method still works under system seven as long as you don't set
the apple event bit in the size resource.

After that works, you can then change the FREF's of your app to tell
the finder what kind of documents you can open. The "****" is the
magic string for opening any type of document.

Thanks -- that's exactly what I needed. Not knowing what to look under
in SpInside Mac, and certainly not thinking to look in the Segment
Loader chapter for this, it would have taken me ages to find it. Just
the proc call names was enough to search and locate the descriptions.

The app has to work with System 6 (it's a utility to supplement the new
version of the America Online software), but wanted it to accept dropped
files as well since the file type that it opens would probably not be
owned by my app.

Thanks again.

Recently I tried rebuilding my macapp library, and was surprised to find out
that it wouldn't compile it in debug mode.
The problem was that the compiler directive qMPW31 was set TRUE, although
I am using MPW 3.2 .
I set it to FALSE and it ran smooth, but I don't get it, what went wrong ?
Is it a known bug, or was there something wrong in my installation of MPW ?

It's documented in the documentation. Also, MacApp 2.0.1 is officially
*not* supported with MPW 3.2. Works anyway.

This message occurs when you run, not when you compile. In any case, the
problem can be fixed by obtaining and applying the THINK Pascal 4.0.1
patcher program.

  This problem can also be caused by the older versions of Gatekeeper, the
shareware Virus protection system. Upgrade to the newest version (if you are
using it) and the problem disappears.

  As an aside, you should also upgrade your THINK Pascal to 4.01, using the
upgrade kit available on SUMEX.

What's the best way of finding out whether a font, whose name
and number I have, is the system font? Under ordinary,
English/American Roman script, it's easy: the font has number
zero.  However, under non-Roman scripts, this isn't the case:
under a Japanese system, the system font is Osaka, which has id
$4000.

So, how do I tell? Is the bottom word always zero?

Post or email, I don't mind.  Thanks.

  The resource ID range for 'FOND' resources has been divided into ranges for a
particular script.  For the Roman fonts will be in the range 0 through 16383.  There
are further subdivisions of this range, which I don't remember the full details of.
(There's a range reserved by Apple, another range reserved for renumbering families
when ID conflicts occur, etc.)
  For script systems with script codes between 1 and 32, you can derive the ID range
for a script by the formula 16384 + 512 * (script code - 1).
  For script systems with script codes between 33 and 64 (there aren't any of these
yet) you can get the range by the formula -32768 + 512 * (script code - 33).

  Of course, whether a particular font in question follows this convention is
another story.  I just ran across a Japanese font yesterday that the system thought
belonged to the Gujaraiti script system because it was in the wrong range...

I believe that calling _FlushVol has always flushed the Control Panel disk
cache, among other things.

IM 6 is slightly misleading in its statement about the cache. Even under System
6.0.x, you were never able to completely turn off the cache. The File System
always kept a small cache going, even when you set the cache to zero. System 7.0
is just being honest about it.

Subject: Max files shown in GetFile dialog and Mac video?
Date: 4 Jun 92 01:49:27 GMT
Organization: UTCS Public Access


I'm writing an app that will need to access numerous files at a time.
Just as a test, I hacked out a routine that created 1500 null size files
in a folder and then used a standard get file routine to open the folder
in order to select a file.  As I expected, only about 700-800 of the files
where displayed in the dialog (they all had relatively short names - 10 chars).

The question is: does anyone know of any code that will show more than 1000
files in a folder.  A bad workaround is to let the user select the folder
only, and let my app do its stuff to all the files in the selected folder,
but that's sort of restrictive (e.g. what if the user wants to work on
only the first 500 files in the folder?).

For the curious:  the reason I need to work on such a large number of files
is for video.  If the Mac world is really serious about video, then Apple
has to realize that people in the digital video world (i.e. animators, editors,
etc) work with hundreds and sometimes thousands of files at a time (for
image processing, recording to video tape, and so on). I guess I kind of
take that all for granted using Silicon Graphics workstations.

Along the same lines:  I noticed a thread here a few weeks ago in which
someone asked how to write a file filter that showed only files that
ended in a certain suffix.  Someone from Apple posted back and said that
that was a UI no-no because the Mac identifies files by creator and file type.
That's all fine and dandy, but once again, not entirely appropriate in
today's networked world.  Here's a good example:  i wrote a Photoshop plug-in
that imports and exports Abekas files.  I have NFS/Share (absolutely fantastic
product) running on my Mac and I mount my Silicon Graphics hard disks on the
Mac desktop.  Since unix doesn't use file type indentification, I want my
plug-in to show the user only those files that end in .yuv.  This brings us
back to my original subject - if I have produced a 30 second animation
(standard TV commercial length), I can't see all 900 files in a standard
file dialog.  Poo.

In summary:  If Apple wants to truly address the video market, they are really
going to re-think some of their Mac OS philosophies.

I (as a user) wouldn't want to use Standard File to pick from amongst
1000 files anyway.  This seems like a prime candidate for some creative
user interface design.

Knowing nothing about the video business, it's impossible for me to say
what that creative UI might be, but there's gotta be a better way than
giving the user a flat list of >1000 items to pick from.  If there isn't,
my condolences to video producers everywhere...

No.  But it's not like it'd be hard to write.

Then the user could put those files in a subfolder, to name one
possibility.

And if you're really serious about programming for video, you'll write
the code that it will take to give your users a real UI to work with
those thousands of files.  There are lots of possibilities.

The "Don't Abuse the Managers" Tech Note applies here, except to the
Standard File calls.  If the toolbox doesn't work for you, no one will
stop you from writing better routines.

Incidentally, I would _not_ want to use your program if I have to scroll
through a list of 1,000 files to pick out out at a time.  You'd better
provide multiple discontinuous selection, regex selection, selection by
date and time, and selection by file size, for starters.

>Since unix doesn't use file type indentification, I want my

The best solution is to scan for .yuv files that have whatever
type/creator they have when you bring them over from the other computer,
and give them an appropriate type and creator.  I have exactly the same
problem here, except with dozens instead of hundreds of files.  I put a
"Convert Files" button into the SFGetFile box--it works like a charm.

>In summary:  If Apple wants to truly address the video market, they are really
>going to re-think some of their Mac OS philosophies.

This is a UI question.  The File Manager is not at fault;  the Standard
File calls are.  There are no built-in limitations.  Apple can't
possibly give you the UI you need in this case, so their philosophy is
(and should be) that it's up to you.

Well if I were designing this app I would use some kind of file
browser interface something like Retrospect. I would include
wild card grouping and all kinds of file selecting functions. I don't
think I would use Standard File but it could be done.

Maybe you could write a file filter that pre groups things for the user.
For example: If there were a 500 files and the names were the same
except there is a number that makes them different (ie macvideo1, macvideo2,
macvideo3, etc...) Then in the sfdialog would scan the disk and count or group
the files that are  similar. So in the list the user would see
"macvideo[1-500]" or just "macvideo" since the user is not interested in the
single frames per se, but wants the whole group.

This is an isolated case and don't think Apple has to change anything. I think
it up to you to come out with a useable interface. May the best interface win.

Matt
