Actually, System 7 IS multifinder.  There's no way to turn it off.  You're
stuck with it.  You'll be fine.  My powerbook can't run Think C because
I have only 2 megs of ram.  But apart from that, you should have no trouble.

I'll join with the crowd that recommends the second edition of
"Macintosh Programming Secrets".  I found the text to be very readable
and the topics covered were the very ones I was most interested in.
You can order a disk of all the programs in the book for an additional $20.
The programs were written using Think C so they will work right off the disk.
(Provided you recompile them on your machine.)

The 0,1 and 2 are bit numbers, as is the standard for gestalt...Attr
selectors, as described on page 3-34 of Inside Mac VI.  Thus, if
you were in 32-bit mode, the response would generally be $00000007, or
binary 00000000000000000000000000000111, having bits 0,1, and 2 set;
the same Mac in 24-bit mode might return $00000004 (binary ...0100),
having only the 32-bit capable bit set.

In a little program I'm working on, I'm trying to allocate memory for an

checked my heap before the NewPtr - I have 500K free, and am trying to
get only 32K. - and the heap has only 900 or so bytes used
non-relocatably.
 
After the NewPtr call, I get the pointer, but my heap has been eaten -
now it shows a HUGE 300K nonrelocatable block in use.
 
anyone have ideas about the cause of this?

Don't set FInfo->fdLocation.h and v to zero. Call PBGetFInfo first, change
the fields that you need to, and then write out the result.

Shareware, Freeware, Postware or Software.
It is better if written in C. 
Sources does not need to be given, it can be a library.
Available for Lightspeed Pascal or C, or MPW.
It should behave exactly as the Toolbox TEdit and be, regarding the tollbox

THINK C 5.0 also has this glue.  (As a matter of fact, the glue for
THINK C was more or less a copy of the MPW glue, as a Symantec rep
told me.  In other words, if the glue's in MPW for something, it's
also in THINK C).

This brings up another point: what is the complete list of functions
with glue:  I know for a fact that HOpenResFile() and the high-level
hierarchical functions like HOpen() have glue.  Does anyone have a
full list?

Yep. It's $30 plus tax. $25 if you get one of those purple cards from

ResEdit has a problem that I've noticed twice now.  For no apparent reason,
ResEdit will stop working.  When you try to open a resource file, you
simply get a dialog box with the message, "Resource not found  -192"
and nothing else.

This happened once before and I reinstalled ResEdit and the problem went
away.

Does anybody know what resource it is looking for (perhaps I can fix it)?
Does anybody know of a fix for this simple, yet annoying problem?

Any hints welcomed.

      If you have to ask, you can't afford it.

      Ed Yourdon, in "The Decline and Fall of the American Programmer",
points out that a tool suite for a programmer in a commercial environment
now costs about $10,000 per year.  Yourdon tends to be oriented toward
IBM mainframes, but it seems that small computer tool prices are
rising to that level.

      It doesn't really matter, though, because 75% of software sold at
retail comes from the top 11 firms.  The era of amateur programming is
drawing to a close.

System 7 does away with MultiFinder. Think C works great along with the
debugger under system 7. Symantec should change the documentation to reflect

The perfect book to start with is 'Macintosh C Programming Primer' (get the

has lots of sample code. You can order the disk of code seperately.

IM also doesn't say that locking the handle is necessary before calling
DrawPicture.  I don't recall reading this in a Tech Note either.

DrawPicture itself isn't the thing that accesses picture bytes, since this
can be overridden in a capture proc.  If you disassemble StdGetPict,
however, you see that QuickDraw keeps a handle to the picture and the
offset within the picture in private variables and dereferences the handle
each time it needs to access the picture.

There must be some other explanation.

In general, if the system accepts a handle as input, then it is prepared to
deal with the consequences of the handle's data moving.  The only exception
I know to this is playing a sound handle asynchronously.  (Even then that's
not strictly an exception because the Sound Manager does lock down the
handle for the duration of the call; it's just that when called
asynchronously the sound plays beyond the extent of the call.)

Hello,

working with Think Pascal and ResEdit (and being mondo pissed that the
Pascal manual nowhere mentions that you need ResEdit for creating resources),
I had the following questions:

1/ using system 7 I would like to have both Pascal and ResEdit open, but
if I'm editing the resource, Pascal has trouble finding elements (menubar
for instance) in it. So I have to close the resource every time I want
to test run the program. Is there an explanation / work-around for this?

2/ I have programmed mouse-and-menu programs before on the Atari ST, and
the resource construction programs there gave you a possibility to
give symbolic names to items in the resource, which you then used in your
program. This way alterations in the resource do not necessitate alterations
in the program. Is such a thing possible with ResEdit, combined with Think
Pascal?

Thanks in advance.

Victor.
