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

The digest is a collection of article threads from the usenet 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.  If you don't have access to news, you can
post articles to any newsgroup by mailing your article to
	newsgroup@cs.utexas.edu
So, to post an article to comp.sys.mac.programmer, mail your article to
	comp-sys-mac-programmer@cs.utexas.edu
Note the '-' instead of '.' in the newsgroup name.  Be sure to ask that
replies be emailed to you instead of posted to the group, and give your
email address.

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
recent issues are available from sumex-aim.stanford.edu [36.44.0.6] in the

/* Please note the comments in the code indicating what portions of */
/* the code should be commented out in order to remove either */
/* the automatic condensing or the automatic ellipsis removing */

/* A suggestion to beginning LDEF programmers: try modifying the code */
/* slightly: for example, use a couple of bytes at the beginning of */
/* the data you pass in to store style and font info.  This way, */

The resource manager can now decompress resources.  Does anybody know if
there is anything (code examples, application, etc.) that will let us
compress our resources or is Apple the only one able to take advantage
of this feature of the resource manager.?

Thanks in advance,

There is an article in the January MacTech (formerly MacTutor) about
resource compression.  It describes how the Resource Manager handles
compressed resources as well as how to implement your own resource
compressor.  If you're looking for an off-the-shelf product to
compress resources for you, check out VISE from MindVision.  I believe
that some of the major compression applications can also do resource
compression, but I haven't personally used any of them.

Chris.

If you look at the dialog that comes up if you hit the "Get Resource Info" menu
command while looking at a particular resource, one of the options available
with its check-box is compression. I haven't ever checked this box, but I know
it is there.

Checking the box won't compress the resource.

Apple has not released the resource compression info to the
public (though certain companies have reverse-engineered it)
This was because of the time constraint; resource compression
was sort of a hack to get a System 7 on a HD floppy.

re cleaning it up, modularizing
it (as always :-) and will release info for developers "sometime."

In the meantime, you can always head-patch GetResource to do
the thing for you. Head patch, you say? Well, a patch that
looks something like:

	SetResLoad ( 0 ) ;

	h = GetIntendedResource ( ) ;
	if ( ! * h ) {

		LoadResource ( h ) ;
		if ( * h ) {

			UncompressMyFormat ( h ) ;
		}
	}
	SetResLoad ( 1 ) ;
	JMP GetResource    <- This will find the already loaded resource!

I think Kent Borg was the guy who came up with this genial
solution; hope he doesn't mind sharing it (at least he
gets the credit :-)

You probably have to patch GetIndResource, GetNamedResource,
LoadResource etc as well.

Yes, I posted related stuff once and credit is always nice, thanks.
(But was it really MacDTS that suggested it?  I forget.  For good
measure, give them credit too--it spreads the blame...)

|>You probably have to patch GetIndResource, GetNamedResource,

And that is a problem.  There are lots of ways of get resources,
growing all the time, and trying to catch them all, for everybody,
always, is tricky.

If you have a specific resource you want to have an INIT tamper with
before letting the Real Application see it (like a 'PREC' 103 in
printing--my case) shinanigans like mine might be for you.

If you just want to decompress resources, look at the January 1993
MacTutor aka MacTech article.  Apple can't break their own scheme
anytime soon without breaking all the 7.0 floppies they shipped.
Sure, they might do a better (read: bigger, meaner) solution, but if
this one works now and plans to keep working, why not use it?

[The 7.0 resource compression scheme in summary, via Justin Gray of
Alysis in MacTech: Put a 'dcmp' code resource in your file (great new
virus vector!) that knows how to decompress your resource, then mark
your compressed resource as compressed and point to the correct
'dcmp'.  And when anyone wants it through any calls, you do some fast
"single-buffer" decompression and they are there.]

I know a developer who liscnses his resource compression technologies for
mac applications and resources. Using them you can shrink the size of your
application dramatically.

Also using good compression in your application can make it load faster,
especially from floppies or on fast machines.

The developer I am speaking of has compression faster loading, and
smaller, than all known resource compression technologies. (Using Norton
utilities as the benchmark application.) Over 400,000 und users have run
his code in varioius products, but as advertising is frowned upon on the
Internet, you should contact me via E-mail for his company number, prices,
specs, etc.

PS. His resource compression is not only the smallest out there, it also
makes some applications smaller than when compressed with traditional,
non-resource compression technologies such as Compact Pro 1.33, etc.!!!

He also has a near-100% resource compressed system 6.08, microfinders, better
compression of System 7, compressed finders, micro-Finders, etc. All for
people who need to distribute utility software.

There's no standard method for all control panel settings, but I'll give you a
direct answer to your question about getting the highlight color:

rgbColor = (*((GVarHandle)someCGrafPtr->grafVars))->rgbHiliteColor;

...but make sure it's really a color GrafPort before you do this.

It lives at low mmeory $0DA0.  Here's an old piece of Pascal code
I have that uses it:


		BlockMove(Ptr($0DA0),@hiLiteColor,SIZEOF(RGBColor));
		RGBForeColor(hiLiteColor);

hiLiteColor is declared as an RGBColor.

I like to creat a list containing file names, size, date etc. Each entry
should be in a single cell. After I put file name in the cell using
LSetCell, I have to add size, date etc. in the same cell. Although I can
use LAddToCell to do that but that will make the size field not aligned
vertically. Anyone know an elegent way to handle this? Thank you very much.

BTW. I am using Think C 5.0.3, have lots of trouble with C and Pascal strings.

To do what you want, first BEFORE creating the list, set the font
for that list to Monoco.  This will set it to a mono-space font. 
Any other monospace font will work as well.

next, with the file name do the following

	Str255	fName;	//* i assume you have a Pascal file name
	char	lineBuf[128];



	PtoCstr(fName);
	sprintf(lineBuf, "%-32s", fName);	//* this will put the file
name left justfied in the string, padded with spaces, change the number
as you need.

	dataLen	= strlen(lineBuf);
	LSetCell(lineBuf,dataLen, ....etc

When you do your LAddToCell(), do it in similar manner.

One hint, I just discovered this morning that if the text is longer
than the entire width of the window, it will condense the type to
make it fit.

On your other question, as far as I know, Think C does not support,
	 mystring="\p Something ";

use
	strcpy(mystring, " Something ");
	CtoPstr(mystring);

or
	sprintf(mystring, "\p Something ");

be sure to 
	#include <string.h>
	#include <stdio.h>
and Link ANSI

ThinkC DOES, in fact, support Pascal string literals.  P. 206 of the
ThinkC 5 manual states "To write a Pascal string constant, start the

I missed the beginning of this thread, where mystring was apparently defined,
but perhaps the key is that:

mystring = "\p somthing";

works if mystring is declared as an unsigned char *.
It *doesn't* work if mystring is a Str255 or any other array construct where
the actual storage is allocated on the stack.

That will work, but you can write your own LDEF to display any
information in any format you like.  An LDEF is probably the simplest
proc code you can write.  You can get some pascal sample LDEF code
with my Talk source code on
sumex-aim.stanford.edu:/info-mac/source/pascal.  There is probably some
sample code on ftp.apple.com:/dts/mac/sc somewhere.

The normal technique is to store a record/struct of the information you
want and then write an LDEF proc to display it.

Good luck,
   Peter.

Wow, and I though I was just doing something stupid. I encountered
this condensing "feature" recently, and I haven't been able to the 
goddamn thing off. (No using a monospace font does not work).
As far as I can tell, this condensing only occurs when
you use Lists in a Modal Dialog (leading me to suspect that this
is some hack introduced to aid in displaying long file names
in the StdFileDlog, or something like that).

The reason I want it off is that I'm displaying columnar data in a
List, and when ListMgr condenses it, it throws off alignment with
column headers (Yeah, I know I can put the data into individual
cells, but its not worth the effort in this situation).

Does anyone out there know how to turn off this "feature"?

List Manager does this to lists in regular windows, too.  If condensing the
text is not enough to make it fit, LM will also truncate the text and put
an elipsis "..." at the end of the part that gets displayed.  What I would
like is to turn off the condensing part, and leave on the truncation /
elipsis part.  Does anyone know how?

I wasn't aware of this feature, but it would seem that this behavior must
be a part of the standard LDEF, since the List Manager proper has no
knowledge of the meaning of the data in the cells or the way that those
data are drawn by the LDEF.  (How would the List Manager 'condense' cells
where the data are icons rather than text, for example?)  If this
assumption is correct, then my recommendation would be just to write your
own LDEF to display text as you like it.  This ought to be pretty simple
and straightforward to write.

I wonder if this text-condensing LDEF is some new version written for
System 7.  I haven't observed this behavior in earlier systems.

You could always do it the good old fashioned way - add the elipse on
yourself if necessary and use StringWidth to figure out making it fit in
the list.  Here's some code I used a while back, of course, its probably
not script manager compatible :-)

	procedure DotDotDot (var s: str255; var width: integer);
		var
			maxwidth, len: integer;
	begin
		maxwidth := width;
		width := StringWidth(s);
		if width > maxwidth then begin
');
{$PUSH}
{$R-}
			len := ord(s[0]);
			while (len > 0) and (width > maxwidth) do begin
				width := width - CharWidth(s[len]);
				len := len - 1;
			end;
			len := len + 1;
			s[0] := chr(len);
';
{$POP}
		end;
	end;

I'm not sure why you want to disable the feature - true it looks a bit
strange, but it's what you'd do if you weren't on a computer, seems pretty
sensible to me.

Have fun,
   Peter.

It behaves the same under System 6.0.7 on a IIsi and 7.0.1 on a IIcx.

I think, the guy who did SoundMaster must know how, since he did it in his
control panel...

Re: getting List Manager to not condense text.

To do this, write your own LDEF: if there's interest, I'll post an LDEF
which behaves the same as the standard LDEF, but with comments indicating
which lines to comment out to remove either or both the condensing and
ellipsis adding.  I've found that many of the problems of using the List
Manager can be solved with a very simple LDEF, and writing a simple LDEF
is easy once you have code for one, since you may only need to modify
a couple of lines of code.

Gudday,

I have an application that can't be run when it is locked (don't worry, it'll
never run off CD-ROM or locked file server).

So, rather than worry about dweebs not being able to figure out how to unlock it
I automatically unlock it using HRstLock on the application.

It works fine - except that the application thinks that it is locked until it
quits and runs again.

I have tried running FlushVol afterwards, but to no avail.

Any suggestions? I need to get the system to realise that the file has been 
unlocked. 

Please email or post.

Oh yeah, is there a way of telling whether it is locked or not without changing
that state? Easy way?

The problem is that when the file is locked, the Process Manager can only
open a read-only access path when opening your application to run it.
Regardless of any changes to the file's state, that access path remains
read-only.  Here's my recommendation: if the file's locked and you
unlocked it, put up a dialog saying "MacWidget Pro can only run when
it is unlocked.  The file has been unlocked, but needs to be relaunched.
Please run MacWidget Pro again."  Because this should happen so rarely,
this shouldn't be a huge user problem.  This also gives you a good place
to put up a dialog saying "MacWidget Pro needs to be unlocked to run.
Please unlock MacWidget Pro and run it again." if you couldn't unlock
the file.  (Because it's on a CD-ROM or file server or locked floppy or
whatever.)

If you really really can't do this, and you really really need to
unlock your file, and you don't care if you've got to fix your app
with every new system release from now till doomsday (yes, I'm
trying to scare you), and you promise not to tell anyone I told you
this, and you didn't hear it here, and you won't bother me when it
breaks in a really spectacular way and erases all the hard drives in
a 10-mile radius, then you might be able to do what you want to do:
you could try looking through the FCB table to find the FCB associated
with your app and bashing the "write-OK" flag in the FCB (see the
bottom of Inside Mac IV, page 180).  You might also need to mark
the resource map as read-write.  And may God have mercy on your soul.

> Oh yeah, is there a way of telling whether it is locked or not without
> changing that state? Easy way?

Since the question isn't really "is the file locked" but "can I write to
the file", you should call GetFCBInfo to get info on your access path
to the file (pass the CurResFile() refNum as the refNum you're
interested in).  You check the same bit I told you not to change up
above.

For some reason, the 'gdDevType' device attribute tells you whether or
not the monitor is color.  So once you know what GDevice you're
dealing with, it's easy.  I have some code in my application that
looks like this:

 // Use "color" drawing on 4-bit color or 8-bit grayscale, or better
 Boolean useColor = depth >= 8 ||
                    (depth >= 4 && TestDeviceAttribute(theDevice, gdDevType));

I hope this helps....
