The Comp.Sys.Mac.Programmer Digest is moderated by Michael A. Kelly.

The digest is a collection of article threads from the internet newsgroup
comp.sys.mac.programmer.  It is designed for people who read c.s.m.p. semi-
regularly and want an archive of the discussions.  If you don't know what a
newsgroup is, you probably don't have access to it.  Ask your systems
administrator(s) for details.  (This means you can't post questions to the
digest.)

Each issue of the digest contains one or more sets of articles (called
threads), with each set corresponding to a 'discussion' of a particular
subject.  The articles are not edited; all articles included in this digest
are in their original posted form (as received by our news server at
cs.uoregon.edu).  Article threads are not added to the digest until the last
article added to the thread is at least one month old (this is to ensure that
the thread is dead before adding it to the digest).  Article threads that
consist of only one message are generally not included in the digest.

The entire digest is available for anonymous ftp from ftp.cs.uoregon.edu
[128.223.8.8] in the directory /pub/mac/csmp-digest.  Be sure to read the
file /pub/mac/csmp-digest/README before downloading any files.  The most

Danny W. McCampbell <[e-mail]> asked about adding balloon
help to his app.

Peter N Lewis <[e-mail]> replied:
|Whatever you do, don't use BalloonWriter or you'll spend more time

|The hdlg resource has items for each dialog item.  There is a hdlg
|item in the array for each DITL item, and each hdlg item has four
|strings (STR# id, index pairs) attached to it (Normal, Disabled,

This is fine as long as your balloon help strings are all less than
255 chars long.  If they're longer, you should use TEXT [HMTEResItem]
resources instead.  Another advantage of using TEXT resources is that
you can used 'styl' resources to style the text with different fonts,
sizes, boldness etc.  This can be a bad thing as well, since any font
selected via Leium or whatever will be ignored.  If you want to get
REALLY fancy, you can use PICT [HMPictItem] resources and have nice
colour diagrams in your explanations.

I've always wondered if you could use a 'moov' resource.  A little
animation would make 3D revolves etc. easier to understand, that's for
sure.

Yes, someone(s) at the MacHack gathering this summer presented just such a
hack.  Anyone with back issues of the TidBITS newsletter could find the

TidBITS doesn't seem to have anything about QuickTime in balloons.
Leonard R.'s movie-for-a-finder-icon hack is mentioned (hey, Leonard,
want to upload that somewhere?) but that's it.

Maybe Wild Magic would let you substitute a movie for a PICT somehow?
(I'm not into QuickTime;  if this is a dumb idea, flame me in email.)

You couldn't use the interface anyway, without seriously distorting the
balloon help UI.  Would continuously-looping balloon movies really be
that informative?

You're right, Jamie, the movie was in a Finder icon, not in a balloon.  My
error.  I think I'd rather see the movie in an icon, especially if you could
turn the movie on and off by selecting/deselecting the icon.

I attempted to place a QuickTime movie in balloon help within a Prograph
application. It was very easy to do because Prograph has a very nice
built-in balloon editor. However, when I bring up the balloon, there is
no way to go and activate the QuickTime movie. I am using Wild Magic,
which has a small icon which must be clicked to deploy the QuickTime
movie controls. Once you mouse out of the object to which the balloon
help corresponds, the balloon goes away. Therefore, I cannot click on
the Wild Magic icon.

I certainly can see the value of QuickTime in balloon help. I hope that
someone will make it possible.

Subject: Problems in Macintosh Programming Secrets
Date: 4 Sep 92 01:01:09 EST
Organization: Univ. of Cincinnati Center for IT Services

I'm trying to get the example programs to work from the Second Edition of
Macintosh Programming Secrets by Scott Knaster and Keith Rollin.  I'm having
a little trouble with the program in Chapter 4, specifically with the changes
to the MainEventLoop function in Standard Stuff.c.  The line in question is:

    itemWasHit = DialogSelect(&event, &theDialog, &itemHit);

When I try to compile the source file, I get the message " 'theDialog' has
not been declared."  There is another occurrance of 'theDialog' a couple of
lines later, so I don't think it's a typo.

As far as I can tell, there is no function prototype in any of the files
for DialogSelect.  I'm assuming there should be. (?)

There were other variables in MainEventLoop that no declaration was listed
for, including passToDialog, itemWasHit, and sleepyTime.  I made some
assumptions which I think are correct - I declared the first two as
Booleans, and sleepyTime as a long.

Anyway, can someone tell me what theDialog should be?  A DialogPtr perhaps?
Also, are there any other gotchas to watch out for in the rest of the book?

Thanks for any info.

Sorry for the confusion there. Yes, "theDialog" should be a DialogPtr. Scott I
and didn't want to waste pages and pages going into excrutiating detail on
everything, so we left a few out in some places. Missing declarations whose
types are obvious are such a place. In this case, you know that "theDialog" is a
DialogPtr because that's what the Dialogs.h files says DialogSelect() takes as
the second parameter.

> Also, are there any other gotchas to watch out for in the rest of the book?

You tell me.

To do an animated cursor the way the Finder does it, you have a acur resource
with the numbers of the CURS icons in the rotation.  Make a copy of your finder
and save it to disk.  Look at the acur and CURS resource with ResEdit.

Then, inyour application, you just keep a variable with the current cursor,
add one to it, and then do a SetCursor procedure/function.

Hi there,

Another possible approach is to use the Vertical Retrace Manager.
This is pretty easy if you have New Inside Macintosh: Processes,
since full source code is conveniently provided.

And I didn't like it when I saw it.  No, I have no gripes (or opinions
actually) with the quality of the code, my complaint (often repeated
here) is that a VBL task should *not* be used to spin a cursor.  It is
dishonest.

Spinning cursors are not just there to be cute, they are to assure the
user that things are still progressing, their speed and cadence can
convey information about the progress of short procedures.  (Long
procedures should get cancelable progress thermometers, not spinning
cursors.)

If you use an effort-saving VBL to spin your cursor you are unlikely
to put in the extra work needed to make the cursor representative of
whether there really *is* any progress going on.

Spinning cursors is not a background task, it is part of the Real Work
of your application, do it in the Real Code.  Save VBLs for background
activities.

Subject: Q: GrayRgn + Menu bar region
Date: 6 Sep 92 20:38:06 GMT
Organization: Brown University

With WaitNextEvent() you can specify when to receive mouse
moved messages by specifying a region within which you don't
care about the mouse's movement but outside of which you do.
When the mouse is outside of the front window, I only care to
be notified when the mouse moves into the front window. This is
simply done using a region that is the difference between the
desktop and my window, for example

        RectRgn( theWindowRgn, &theWindowRect );
        XorRgn( GetGrayRgn(), theWindowRgn, theCursorRgn );

The problem is that GetGrayRgn() excludes the menu bar and so I
get mouse moved messages when the mouse moves there. Is there a
clean way to get the full screen region (desktop and menu bar)?
Thanks.

You don't need to be so selective. Instead of using GetGrayRgn(), create a
wide-open region from -32000 to 32000 in both directions, and subtract the
theWindowRgn from that. This technique will only cause problems if you move the
mouse off of the desktop, which you can't, so it won't, so there.

Here's how TESample on ftp.apple.com does it:

/*    Change the cursor's shape, depending on its position. This also calculates
the region
    where the current cursor resides (for WaitNextEvent). When the mouse moves
outside of
    this region, an event is generated. If there is more to the event than just
    Rthe mouse movedS, we get called before the event is processed to make sure
    the cursor is the right one. In any (ahem) event, this is called again before
we
    fall back into WNE. */

#pragma segment Main

    RgnHandle    region;
{
    WindowPtr    window;
    RgnHandle    arrowRgn;

    window = FrontWindow();    /* we only adjust the cursor when we are in front */

        arrowRgn = NewRgn();

I did it recently this way, to play a sound asynchronously:

I used ResEdit to create (and preview play) a 'snd ' resource (trailing
blank required) with the following hexidecimal values.  Actually, I created
a template for ResEdit to make this easy.  Sound resource number should be
above 8191.  I used 9000.

============   'snd ' RESOURCE:

0001               Format 1
0001                                                   Number of mod/synth's is 1
000100000000       Note synth id is 1, and null initial parm
0003               Number of commands
002B00FF00000000   Amplitude command (full blast)
002C008000000000   Timbre command (half between square and sine)
002803E800000036   Note command (1000 half miliseconds, F-sharp/A-flat)

============  TO PLAY THE SOUND:

SndCommand    myCallbk;

- ------------
disposeAlmaMater = FALSE;
myCallbk.cmd = callBackCmd;
myCallbk.param1 = NIL;
myCallbk.param2 = (long) &disposeAlmaMater;
SetItem (myMenuHandle[3], AlmaMaterItem, myStifleStr);
mySoundH = GetResource ('snd ', 9000);
HLock (mySoundH);
mySndChPtr = NIL;
myErr = SndNewChannel (&mySndChPtr, NIL, NIL,
    (ProcPtr) myCallBack);
myErr = SndPlay (mySndChPtr, mySoundH, TRUE);
myErr = SndDoCommand (mySndChPtr, &myCallbk, TRUE);

============   TO STOP THE SOUND

sndRC = SndDisposeChannel (mySndChPtr, TRUE);
HUnlock (mySoundH);
ReleaseResource (mySoundH);
disposeAlmaMater = FALSE;

============   CALLBACK ROUTINE

pascal void    myCallBack(SndChannelPtr workChPtr, SndCommand workCmd)
{
    *((Ptr) workCmd.param2) = (char) 0x08;  /* set flag in disposeAlmaMater */
    return;
}

============

I'm a real beginner at this sound stuff, so postings of any other ways
would be of interest to me as well.

I am not sure this is the right place for this, but if it isn't, please
flame in toward the right newsgroup. :)

It occurs to me that it would be quite neat (to say the least) to get
rid of this memory zone stuff in the Macintosh by making NewHandle
act like TempNewHandle. Or more precisely, to make any call to NewHandle
result in a call to TempNewHandle, and if that fails, a normal call
to NewHandle.

I tried to make an INIT that does this, but it failed miserably, and I
don't understand these things well enough to know why, or to fix it. :(

So, I just wanted to suggest that somebody out there with a clue about
these matters give it a shot, or tell me its impossible (& why). :)

Dat's all. Thanx fer listening. :)

This was discussed at length some months ago. Some guy who was Smarter
Than All the Rest of Us Put Together pointed out that this was going
to make some existing applications go crazy. Some do brilliant things
like figure out how much memory is available to them and then allocate
it all in one big block and do their own allocation schemes within that
block. MacPaint 2 is one that springs to mind. Or perhaps MacWrite II.
One of those.

Why would this cause a problem? Sounds to me like it calls some Mem Manager
routine to find out how much memory is in its zone, then allocates a block
about that big. Is this not what you are saying?

All taht would imply is that you ought to try to NewHandle before
you TempNewHandle, or some such thing like that, so this allocation
would (if possible) be in the app's zone instead of in temp memory
(where it could get in the way)

At the worst this just means there needs to be a mechanism for
exceptions to the new memory-allocation arrangement, no?

I feel only very large blocks of memory that NEVER ar locked during a call
to waitnextevent should be put in temporary memory.

It sickens me to have to reboot all the time in system seven on a stock
system on a 8 meg machine (not mine) because even after quitting nearly
every application the damned free memory is fragmented AND LOCKED by
foolish people who abuse temporary memory.

That's the Apple dogma, as well as I remember.

No, it's bugs. Get the latest Tuner. I never have this problem, and I'm

Subject: UseResFile() problems with CTB Tools
Date: 7 Sep 92 23:52:18 GMT
Organization: Royal Institute of Technology, Stockholm, Sweden

I have a document from Apple (by Craig Hotchkiss and Chris Halim) that
describes some hints when creating your own Choose dialog:

...
Save CurResFile().
Save the current grafPtr.
Set the new grafPtr to the dialog.
Set CurResFile() to the procID of the tool we're working with (the tool procID
    is also the refNum of the open file).
...

But when I check with ResError() after UseResFile((**toolHandle).procID) I get
error resFNotFound (-193) Resource file not found. Can anyone explain why?
The tools handle is valid and the code works fine without UseResFile() stuff.

Now, I really want to use the refNum to the actual tool and read some font
resources. Do I manually have to locate the tool before doing this?

Thanks for any help!

ulfis

PS: Thanks to all of you netters that helped me earlier with strange font and
    sizes in the Choose dialog. I'll post the complete code to the net when
    it's done and works! DS.

Not to be a pain, but why do you need to do that?  The only reason I ever
came up with for that was printing, but you can always TMPaint to a
printer grafport for that.

The tool itself contains font information to be used in the tools settings
dialog. I should read this information from the tool to make my custom choose
dialog look good.

Most tools contain a 'finf' resource that tells what font, size and style to
use for the settings dialog. I tried to use this resource, but found that
some tools don't have it.

What am I supposed to do if there isn't such a resource? The tool I found that
was lacking this resource, apparently wanted Geneva 9. Should I set the font
to Geneva 9 if I can't find this resource?

    That's true.  Also, with System 7 there is a NEW resource type that is
used by the xxChoose routines to track font/size information for a tool - the
'flst' resource.  So what you now have to do is check system version - if
7 then look first for a 'flst' (Get1IndResource) and if you don't find it, then
go for the 'finf'.  Under 6, just get the 'finf'.

    If you don't find a 'finf' or 'flst' resource, then you should use
either Geneva 9, or be internally cool and use the Script manager to load the
the current application font & size.

Hi.  I have a modal dialog that I want to draw an ICON resource

Try

    GetDItem(dlog, Item, &IType, &IHdl, &IRect);
    ReleaseResource(IHdl);
    IHdl = GetResource('ICN#', id);
    SetDItem(dlog, Item, IType, IHdl, &IRect);

Since an ICON resource is a proper prefix of an ICN#, you shouldn't have any
problems.

Subject: CTB undocumented routines and Think Libs
Organization: Royal Institute of Technology, Stockholm, Sweden
Date: Tue, 8 Sep 1992 21:35:13 GMT

The file <CommResources.h> contains the glue for some *undocumented* CTB
routines:

...
pascal Handle CRMGetToolResource (short procID, ResType theType, short theID);
pascal void   CRMReleaseToolResource (short procID, Handle theHandle);
...
pascal OSErr  CRMFindCommunications(short *vRefNum, long *dirID);
...

When I use CRMGetToolResource() in my code (CommToolbox library added) I get
a "undefined CRMGetToolResource" link error.

I can't find any description in my Inside CTB (published 1991) or in
MPW's 411 help file for the CTB. Can someone from Symantec or Apple help me
out?

Tnx!

    These routines are part of CTB 1.1, which is available as a separate
library for Think, but should be part of the MPW 3.2 .o files.  If you don't
have the docs/library for the CTB 1.1, they are available on ftp.apple.com.

The 1.1 files come in MPW .o format.  You need to run it past oConv (and
create a vocabulary file if you want lower case in the names).  I think I
also had to make a small change to one of the header files in that package
as well (or I got newer ones from the ETO CD - I forget).

Can you be more specific about the docs? I looked on ftp.apple.com yesterday,
but did'nt find anything new that I don't already have. I got the HyperCard
stacks from WWDC, but no info there about CRMGetToolResource().

Thanks! I have ETO#8 so I'll look there. Any plans from Symantec to support
this 1.1 version of CTB?
