Dear netters,

I have a few 256K SIMMs available for the first to ask, free.
All you got to do is email me.  I'll send you our postal
address, you send me back a self-addressed envelope stamped
with 75 cents, and the SIMMs will be yours.  Also, let me know
whether you want 2 or 4 SIMMs.

Ciao,

                Hisham.

hello,
  my program runs great when launched as an APPL or from think-c, but
does terrible things in the debugger.  first it crashed at insertMenu.
so i used an MBAR resource.  then it crashed at getnewcwindow.  so i
called that earlier then i got passed those and crashed somewhere else.
where is probably irrelevant so i didnt check.
  what could cause this?

In mail.think-c you write:

The problem is isolated to sites not providing rapid enough name
server responses, or something like that.  Supposedly, the network
people at UCI are working on making the server less sensitive or
whatever is necessary to resolve this problem.  I've been keeping
them aware that this is causing trouble for people on this list.  If
all else fails, you can always use the mail server until the ftp
daemon is repaired.

I've been informed that the failures stem from a kernel bug in the
Dynix operating system running on ftp.ics.uci.edu.  Until it is
fixed, you can connect via an alternate ftp port:

Example:

The problem with the regular server should be resolved within a week

The old tired and worn "Floating Palette" Subject.

I have some code that doesn't quite work, not sure where I got it. I been
hacking at it for awhile. Does anyone have anything they would be willing to
share, or I'd be willing to send what I have for public smashing, just to get
something that everyone could use.

I need a library that would do the following:

% Support multiple windows
% Be easy to use. Simple API One call to add a window, one call to remove a window
% Be in straight Think C, not in object C

What I have now replaces the following functions: FrontWindow SelectWindow
DragWindow ShowWindow HideWindow

I've added these to manipulate all the windows at once: ShowFloatingWindows
HideFloatingWindows

It originally started with support for only three windows, or course I needed
four, so my mods sort of work, but there are a few strange bugs.

Thanks for the bandwidth.

Aloha,

Does anyone have a hypot function for Think C which implements the overflow
and underflow results which BSD describes?

I would assume that the prototype would be

double hypot( double x, double y);

It would probably be useful to add to the TC archive since a lot of C
programs assume it's there and it isn't in Symantec's version.

The only real limit to the maximum number of open files is the Mac
File System itself. Under System 6, you're limited to a number that's
determined by the contents of your boot blocks (typically 40). Under
System 7, you're only limited by available memory.

Go ahead and change FOPEN_MAX to whatever you like. BTW, the other
three files that you're missing are stdin, stdout, and stderr.

When I use a fancy color pattern (128x128) the debugger starts to eat
100k of its heap (as seen by Swatch). This occurs for every step o
peration after calling StandardGetFile (but in another project it
happened unrelated to StandardGetFile...). This behaviour is totally
repeatable.

This is on a MacII fx, 7.01 Swedish, Tune-Up 1.1.1, 32 bit addressing,
32 meg physical, no virtual, no inits (i.e., shift key at bootup), a
color startup pict, 3 monitors both color and B/W, several HDs. If I
revert to a Control-Panel compatible pattern then everything works
fine even with all my usual gazillion inits.

Subject: Question : Appmaker and THINK C
Message-ID: <[e-mail]>
Newsgroups: fa.think-c
Lines: 27
Date: 5 Sep 92 00:53:02 GMT

Folks,

Very simple questions.  First time user of AppMaker with THINK C.
I have defined few windows and menu bar items using AppMaker.  Then
I let it generate code in THINK C.  It compiles fine.  One other thing
I have done is cut and paste pictures ( PICT Files ) from the ScrapBook
onto some of the windows.

So the scenario is like this ;

When you fire up the application, there is a pictorial tool palette on
the LHS.  So there are 3 to 4 PICTs on the LHS.  WHat I want to do is
click on a PICT and go to another window.  And if I click on a different
PICT, I want to go to a different window.  But the code that has
been generated includes only one procedure called MouseInWindow where
I have written the code to be able to jump to another window.  So the
way it works now is no matter where i can click on the window, it goes
to the same one window.

The code that was generated using AppMaker utilizes the procedural stationary.
Anyone out there in the networld can help me with this ? Any idea what's
going on and what's the problem ?

Any help in this regard will be highly appreciated.  Thanx much in advance.

    OffsetRect(&dispBounds, -dispBounds.left, -dispBounds.top);

In one project, it compiles fine.
If I move the code to another project, it will not compile again.  It says
"Syntax Error", and my C compiler does not seem to know what a Rect is?!!!
I have all the correct #includes, as it does work in one project, but not in
any other.  I checked the Compiler options, and they are also the same from

Has anyone else had this problem?

I got a number of responses to my question on why an unsigned short didn't
seem to be accepting a number between 32,767 and 65,535.  I wasn't using a
printf statement so the answer was not that I needed to specify it with a u
instead of a d, but I was looking at it in the debugger, and from Steve
Williams answer below, it seems that the Think-C debugger will not display
an unsigned short in decimal format in the correct manner. You have to
typecast it in the data window in order to see it's true value.  Which
brings up the question of just how does Think-C represent unsigned shorts.
Anyway, thanks again for everyone's help:

THINK C uses two's complement binary to represent integers (see the
User Manual, p. 427). The THINK Debugger currently only knows how to
format unsigned numbers as hexadecimal; hopefully this will be
addressed in a future release.

Okay here's the problem.  I have PICT resources pasted onto one window
of this application that I am trying to build.  What I want to do is simple :
cut one PICT resource and paste it onto another window.  I think I should
use COPYBITS to do that.  But I am confused as to what arguments should I
pass on to COPYBITS.  How do take the PICT resource's portbits ? I mean
how do I access them ?

Any help in this regard will be much appreciated.  If possible, please email
your responses to Ramesh at [e-mail].  Thanx much.

- Ramesh

    I am trying to write a dcmd in Think C and I'm having a heck
of a time.  Has anyone done this?  What libraries are necessary?  This
one uses some ANSI calls (sprintf primarily) and a toolbox call (BitTst)
so I probably need a ANSI-A4 and MacTraps but I get all sorts of
link errors when I add converted .o files from MPW that come on the
developer disks.

    Any ideas?

I just put a new version of the Arashi archive in the incoming directory.
The main reason for this is that a file was missing. The missing file
has always been in the sound kit archive, so those who already have it
do not necessarily need the new archive.

I added a short utility program for maintaining the copyright notices

Here's the missing file:

Check out comp.lang.c and comp.lang.c++.  Someone just posted code to do
this to a degree using either C or C++ (didn't look at it, though I did
save it).  The posting is in 4 parts with code, header file, and sample

experience with this patch?  What do the release notes, if any, say
about this?  How is it different from TC 5.0.2?

An upgrade to the TCL was also mentioned.

I spoke to symantec ts today, and they refered me to this posting on the csmp
newsgroup, which I forward to you fellow ThC addicts.  According to ts, nothing
major is added :-(, just fixes some quadra and optomiser buggyness.

----

An new update for THINK C, 5.0.3, has been released. This update corrects
problems with the Quadra and other problems present in earlier versions of the
compiler. Also available is TCL 1.1.2 (the same as that released in 5.0.2).

The patch is available on AOL, CompuServe, and AppleLink, and will be
available on sumex-aim.stanford.edu in the very near future.

  do binary FTP from UN*X machine to mac (Fetch 2.1 is my favourite FTP'er)
  run MacCompress (set Format to UNIX compress)
  I use Stuffit Deluxe 2 to untar, but in PD you could try tar-30 or suntar
Both Fetch & MacCompress3.2 are available from SUMEX-AIM amongst other
quality
FTP sites. Of course you could uncompress/untar on the UN*X machine first
with "tar -xf <filename>" and FTP the result onto your mac, but check "man
tar"

PS I'm hoping that SD 3 includes a Compress capability.
PPS in the near future you would be able to drag the file onto a
uncompress/untar FilterTop module. That is being developed by a group of
enthusiasts under the aegis of TopSoft Inc. and will be freely released
with source. A range of filter/translation modules will be supplied but it
is quite easy to add your own. FTP site: syrinx.kgs.ukans.edu /topsoft

Hello,
  I need to know if a point on screen is touching an icon (the mask).
the best would be if i could convert the icon mask to a Rgn.  Since
i coudn't figure out how to do that i wrote this function.
"theIconMask" is a bitmap.  uh, it kinda works.

Boolean hit(short x,short y)
{
  Point    theHit;

  thePoint.h = x;
  thePoint.v = y;

  if ( PtInRect ( thePoint, &theIconRect ) ) {
    /*here i put x & y in local to bitmap coordinates*/
    x -= theIconRect.left;
    y -= theIconRect.top;
      /*here's where things get nuts*/
    if((*theIconMask.baseAddr+(y*4)+(x/8))&(x%8))
          /*(y*4) for columns in an icon*/
          /*(x/8) to go to appropriate columns*/
          /*(x%8) bit within column*/
      return true;
  }
  return false;
}

anyone?
either fixing the function or converting icon to Rgn would do it?

ps i also tried
    if((*(theIconMask.baseAddr+(y*4)+(x/8)))&(x%8))

There is a new function described in IM VI called BitMapToRegion which
sounds like it would do exactly what you want.  Depending on the system
software requirements of your application, this seems like the easiest way
to go.

thanks to everyone who sent suggestion son sub-lanuching.  I think I've
gotten sub-launching pretty much working now!

However, I've got a document I need to launch, I know it's name, type, and
creator.  I've set up the AppParmHandle to point to my file, and that works
fine.  Two problems remain though.  I'd appreciate any help I can get.

1) I need to figure out which app to launch, given a type and creator.
This is probably normally done by the finder.  I think the necessary info
is in the desktop file, but TN 29 says not to rely on that.  Is there any
kosher way to do this?

2) When I launch an app (say, MSWord) with a doc, it opens the doc, and
becomes the frontmost app.  But then if I switch back to my app, and try to
launch another doc in the same app, the app becomes frontmost, but the
second do is not loaded.  Any idea how do this?  I've seen OnLocation do
it.

thanks!

I think there may be a new command to do this in System 7, but under system 6,
the only way I know of is to march the disk(s) searching for applications and
check the creator against the one you are looking for.  A dirty approach, but
it will work.  You may want to ask the user to find the application for you and
then remember it.  That is what OnQue did when it lost track of the
applications for a file.  (you would have to remember the directory ID, File
Name and Volume Name.)

Under system 7 use AppleEvents to do this.  Under System 6, you would have to
trick the application, the way MultiFinder did it.  You would need to post
events to the application to get it to choose the open item from the file menu
and then patch the SFGetFile trap to paste in your filename and vRefNum.  Way
too hard under system 6.  I would stick with System 7 and Apple Events.

Hi there :

I'm trying to implement lasso.   I'm using THINK C compiler.  What I have is
this :

A picture on one of the windows.  What I do is define a region inside the
picture using rubber-banding.  This works fine so far.

But now I want to be able to cut that region, delete the remaining part
of the picture and then paste back the region.  Following which I want to be
able to generate handles to that region and be able to move it.

I'm using the functions OpenRgn and CloseRgn to define the region.  Thereafter,
I'm using CalcMask and CopyMask to implement the rest of the functionality.
However, I'm confused about the arguments that need to be passed to these
functions.  Any ideas how I can do this ?

Please email your responses to Ramesh at [e-mail].  Thanx well in
advance.

- Ramesh

    Any information on how to change the background pattern? (Stored
at ppat 16 in the system file.)  I was thinking, if you could change the
low memory global that contained the ppat pattern, and then called InitGraf
or InitWindows or something, it would redraw the background, but if there
is an easier (read: better, less evil) way to do this, (I don't even know
if that works!) please let me know.  Another important matter, at what
location is the bafckground pattern stored in memory?  (I assume that a whole
pix map the size of the screen is kept somewhere in memory!)

Anything you know would be really great. Thanks...

Hello All,

I was just wondering if anybody knows if it is true that the Think C
debugger does not get along with any manipulations of the system's
ppat, or whatever the resource is that is the desktop's pattern I
sort of forget. If this is not true, could somebody give me a hint
why a program would work fine w/o the debugger and w/ the debugger w/o
changing the system's pattern, but fail w/ the debugger and a large
system pattern.

I hope somebody out there knows what I'm talking about. I would hate
to think that I'm loosing my mind.

This is what I heard:  a bug in the ThC Debugger copies the 'ppat' 0
resource from the System into the Debugger's heap every time you
single-step.  If you have a complex background pattern, you will
obviously run out of memory rapidly.

I'm not sure if it has to be ID 0;  I think I witnessed it happening
when an ID 16 was the background pattern.  Don't quote me on that.  But
I use the standard 50% gray now and all is peachy.

Hmm, interesting. This might explain why, after installing a nifty desktop

to run out of memory rapidly... :-)

I don't know where I should be asking this, but here goes...

1) Is there a list dedicated to the Excel Software Development Kit?

2) I received the Excel SDK (prerelease 2) in the mail the other day,
and I just tried the "Generic" add-in.   The new menu called "Generic"
appears, and the dialog boxes appear exactly how they're spelled out
in the ThinkC projects...  Generic ALSO has two new functions, it
adds in, too... called Func1(), and FuncSum().   I tried them, but
all I get in both my macros and on the worksheet is an error.

I did some reading in the SDK paper notes, and then tried the following
formula in a Worksheet cell:   =CALL("Generic","Func1","DD",0)
but it just puts nothing in the cell, when it actually should put the
following text in the cell: "Func1".  (cause the Func1() function's job
is simply to return that text string, no matter what is passed in.).

I have NOT modified any of the C code, nor did I need to recompile Func1.c
(instead, I just loaded the Generic Add-in sheet, supplied on the disk.
Generic DOES have Func1() as a CODE resource.

Any ideas?  All I'm trying to do is to get Microsoft's Generic's Func1()
and FuncSum() functions to work.

You mean to say they dont offer any tech support????

Given microsofts proclivity to ship bugs, I wouldnt touch that kit without it.

Have you checked your compile settings and version for compatibility?
It is possible that they are dependant upon non-standard builds of the think-c
librarys.

Have you upgraded to 5.0.3? they probably shipped 5.0.2 (and maybe even 5.0.1),
in which case, you probably should recompile their stuff.

I know! I know! Pick Me! Pick Me!

You need to use a mbar hook procedure*. When the mouse leaves the menutitle
rect, you post a mouseup event in your mbarhook procedure. Menuselect will
then "let go" of the menu enabling you to slide over to the next menu.


* MBarHook=$A2C; See MrMacHook [pointer] I-356

If you need more help I have some pascal code that I can show how I did
this in a fkey. Yes I had an fkey window with a menubar.

Does anybody out there have any experience with commercial database library
packages such as db_VISTA (Raima Data Manager), CodeBase (from Sequiter), or
C-Tree (from Faircom)?

I have an urgent need to add some more robust data handling to an existing
THINK C application, and am looking to by such a package. I have experience
with several commercial RDBMS systems for the Mac (i.e., 4th Dimension, Omnis
3), but nont of these provides an API for C-language programs to access the
data.

The target environment for my application is Mac II level machines with System
6.0.8.  I just need a simple API for C to manipulate four related tables to
support inserting, searching, retrieving, and updating of data in the tables.


So far, it looks like db_VISTA is the most complete package of routines, and
all the info I have indicates that it is also the fastest, but according to
Raima's sales line, it is not available on the Macintosh except as a
"Portability Kit" which has all of the (allegedly ANSI C) source code.  This is
a very expensive proposition (about $3.2K).

CodeBase IV is also only available for a Mac developer as C source code in a
porting kit, however it is much less expensive (i.e. $595).  It claims to be
able to read and write dBase IV data and index files, but that is not a driving
requirement for me.

I don't yet have any pricing or platform availability info for the Faircom
stuff, but they've been advertising in MacTutor for several years, so I gather
that somebody must be using this product on the Mac.

Are any of these commercial packages worth buying?  Has anybody done the
porting to the Macintosh environment?  What kinds of nasty memory management
games are needed?

Please reply via e-mail directly to "[e-mail]" -- I
will summarize and re-post to the appropriate place

Thanks in advance for all help

  Subject:       TCL and Backgrounding
     Sent:       2:46 PM        9/23/92
Greetings,

I'm interested in allowing a computationally intensive TCL-based application to
be put into the background and have it continue processing. I want to be able
to hog the whole CPU while the app. is in the foreground but, once swithced,
become very friendly and do very little on each null event it receives.

What I have now is a big computation loop which iterates at about 100/sec. and
doesn't call "WaitNextEvent()".  I put up a movable modal dialog and update it
to indicate the progress every 100 iterations.

The first thing that ocurred to me was to put a call to
"CApplication::Process1Event()" into the computation loop which would only be
called say every 100 iterations while the app. is in the foreground (maximizing
processing speed while the app. is in the foreground) and perhaps every one or
two iterations if 'gInBackground' is TRUE.

Unfortunately, inside the "Process1Event()" call the switchboard tries to
dispatch an activate event to a null window object.  It looks like
"CSwitchboard::DoActivte()" its trying to get a CWindow object out of a mac
window's refcon.

My questions are.
1) Why doesn't this work? Is it "illegal" to call "Process1Event()"?

2) Is there any way, short of making the whole computation into a bunch of
chores, to get the TCL to behave as I described in the first paragraph of this
message?

Thanks,
Eric

There are a couple of approaches; if you'd like to continue this in
detail, I'll mail you some code snippets, but I thought I'd leave the
general discussion on the group for now, since it might be of general
interest.

This is all covered _pretty_ well in IM-6; I say _pretty_ well because
while all the information is there, it is organized in a manner that
makes it rather hard to use. Also, sound code is generally kind of
tough, because the Sound Manager is unforgiving. The code to use it
isn't that complex, but a slight error can cause truly amazing crashes.

Assuming you want to play a sampled sound from a resource: approach 1
is to allocate a sound channel, load the resource, walk through the
resource until you get a pointer to the sampled sound header, set up
a callback routine which will be executed when the sound is done playing,
and then queue up the sound command. Sound commands can also be somewhat
tricky to use because they don't always behave the way one would expect.

Approach 2 is to use some of the new sound routines which will double-
buffer a sound from disk. This way you don't need to have enough free
memory to load the whole sound resource in and lock it down. On the
down side, these routines are tricky to use.

Jim Reekes, the sound manager guy at Apple, has sample code (in Pascal
still, I believe) which demonstrates doing asynchronous sound play; that's
one of the sample code packages ftp-able from Apple.

Try looking at the sample code first if you an get access to it. E-mail
me off the group if you want to see some of my code.

move it to an ldef resource.  i used a method from pupcdef(i think) to
write several cdefs.  can i do the same for an ldef.  heres the cdef stuff

#define JMP_INST 0x4EF9
#define COMP_ID    294

typedef struct{
    short    jmpInst;
    ProcPtr    addrCDEF;
}fakeCDEF,*fakeCDEF_p,**fakeCDEF_h;

static fakeCDEF_h installCDEF(int idCDEF){
    fakeCDEF_h fakeH = (fakeCDEF_h)Get1Resource('CDEF',idCDEF);
    (*fakeH)->jmpInst    = JMP_INST;
    (*fakeH)->addrCDEF    = (ProcPtr)&WindCDEF;
    return fakeH;
}

fakeCDEF_h fakeH;

fakeH = installCDEF(COMP_ID);

myControl = NewControl ( myWindow, &compassRect,
 "\p.", true, 0, 1, 359, 16 * COMP_ID, 0 );

at cdef resource COMP_ID is a fake cdef

i imagine JMP_INST is the important one to change.

anyone?

The problems I was having when calling "Process1Event()" inside a computation
loop to allow a TCL app. to go into the background while still calculating have
been solved.

The culprit was a manually created (i.e. non-TCL) movable-modal dialog that I
had put up when the computation started.  When the switchboard receives update,
deactivate, and activate events from the Toolbox it assumes that all its mac
windows were created by the TCL and expects a reference to a CWindow subclass
to stored in the window's refcon.

Moral:  Be very cautious about using non-TCL created windows in a TCL app.

The last paragraph of page 475 in the THINK C v5 OOP manual describes what your
application must do if it wants to support a window that is not handled by the
TCL.  Included is a warning that you *MUST* override CDesktop::DispatchClick(),
CDesktop::DispatchCursor(), CSwitchboard::DoUpdate(),
CSwitchboard::DoActivate(), and CSwitchboard::DoDeactivate().

Does anybody know if you also need to override the CSwitchboard::DoKeyEvent()
method as well?  Probably you can think of externally supplied windows that
would like to see both MouseDown() and MouseUp() and not just a "click"--do
these methods also need to be over-ridden?

Just curious--has anybody ever put an external window into their TCL
application?

Just call the following routine with the refNum set to CurResFile(). You
could rewrite it to use other than FSSpecs.

Fellow Think-C programmers,

This is my first posting to this group.  Hopefully it is the correct
forum for a generic Mac programming question.

I'm writing a small program and would like it to be able to tell the
Finder where to position newly created files and folders inside of its
folder display windows.  It's putting the file icons where I want it
to, but I'm having trouble with folder icons.

I have tried using PBGetCatInfo() on a folder, modifying the
dirInfo.ioDrUsrWds.frLocation field, then doing a PBSetCatInfo().
This usually works on folders that have not been recently created -
although sometimes the finder window has to be closed and re-opened
for the icons to appear in their new locations.

When I try the following:

FSpDirCreate();
PBGetCatInfo();
/* change dirInfo.ioDrUsrWds.frLocation */
PBSetCatInfo();
PBGetCatInfo();

the dirInfo.ioDrUsrWds.frLocation field shows the requested icon
position, but the Finder winds up putting the folder wherever it wants
to.

Is there an approved way to get the Finder to do what I want?
Where can I find a list of Apple Events supported by the Finder?

Any help that you could share with me would be greatly appreciated.

Hello,
Would you please add my name to your list of subscribers. Also, could you tell
me how to access past messages from other subscribrers. Thanks.

Now for the help. I have been trying to make a polygon on the screen. I have
Macintosh Revealed and it has a code segment in pascal to create a polygon
on the screen. I tried to translate the code to C but have been unsuccessful.
This is what I tried:
   PolyHandle       thePoly;

   thePoly=OpenPoly();
   MoveTo(150,50);
   Line(100,0);
   Line(0,100);
   etc,  etc,
   ClosePoly();
   FramePoly(&thePoly);
   KillPoly(&thePoly);

This doesn't produce any polygon on the screen. But if I remove the OpenPoly,
ClosePoly, FramePoly, and KillPoly, the lines will draw on the screen. Can
anyone help me?

Another area of help I need is on pointers and the handlers for the pointer.
Thank you in advance,

Newsgroups: fa.think-c

I am having problems with a routine that unpacks a MacPaint file.
The code came from _Macintosh Programing Secrets_ 2nd edition on
page 288:

for (scanline=0; scanline < 720; ++scanline){
    UnpackBits( &sourcePtr, &destPtr, 72 );
    destPtr += (rowBytes - 72 );
}

The curious thing is than UnpackBits is not incrementing sourcePtr
completely - (for example 0x2BC304 to 0x2BC306).

When I run this under the Debugger, the screen freezes up and
occationaly the menuBar has garbage in it.  The sourcePtr is a
valid file, and destPtr is a baseAddr to a valid GWorld PixMap.

What gives?

Hi,
   I just ran into something annoying last night.  A friend of mine is using
his Mac to create a program for a unix machine, which normally thinks that ints
are 4 bytes.  So I told him to turn on the 4-byte ints switch in the
preferences.  I figured that once you did this, you could do this:

  printf("the int is %d\n", i);

And have it work correctly.  Well it doesn't.  The only way to get it to work
is the following:

  printf("the int is %ld\n", i);

If you have run across this before, please ignore this post.  If not, it is
just FYI.  Took me about an hour to figure out what was wrong with my machine
last night. :)

hello Mike, quick response off top of head, but with reasonably high
probability of success is: he needs to recompile the ANSI source code with
32bit ints.  This is mentioned in a note on p172 of the THINK C 5 User
Manual; also see p12 of the Library Reference Manual. You need to do this
for each combination of compiler options, eg native floating-point 4byte
ints ... you plan on using. In my case I've got three versions of the ANSI
library -  normal, one with 32bit ints, and one with 32bit ints/64bit
doubles.

Unfortunately, THINK C linking doesn't appear to verify libraries have been
compiled with the same options. Having prototypes in scope is *not* a
complete solution either, eg if your project is using 80bit floats and a
library has been compiled with 64bit - because you simply can't
cast/promote between these data types in THINK C [I should check manual on
this example though].
    Also I ran across a related problem in developing a code resource for
Prograph. A library of glue routines (XP_support_I) is supplied which you
include in you project. I thought that #including the prototypes for these
library functions would be sufficient, but things simply weren't working if
I enabled the 4byte int option. As I wrote at the time:

Until XP_support_I is supplied in source code form, or all argument types
in its routines are changed to longs, you cannot use the "4byte Integers"
option. Under THINK C 5 it appears that even though the prototype in scope
says all parameters are shorts, the compiler places unshortened ints onto
the parameter stack - it is left for the *called* routine to extract the
shortened form. There may well be a good reason why the compiler works this
way, but the symptom I was getting was that the XPRIMs didn't appear in
Prograph.

The ANSI library can not in any way "know" that you have turned on 4-byte
ints; the machine code doesn't know from types, it just does the two
byte thing when it sees a %d.  What you may want to do is create a
4-byte int version of the ANSI library.  Make a copy of ANSI, open it
up as a project in Think C, check 4 byte ints, and choose "bring
up to date."  Then, use this modified library in your projects which use
4 byte ints (I assume this will work; I've never tried it, but I've done
similar things with floating point options, etc.).  Hope this helps.

Inside Mac is written in terms of Pascal, which allows you to use fields
of a variant record (a union, in C) without qualifying which member of the
union you're using.

THINK C provides macros, topLeft(r) and botRight(r), which, given a Rect,
will return the corresponding corner point of the rectangle.

The thing to remember is that the Mac system was originally written in Pascal,
so it likes Pascal calling conventions. Any other language is more like ass-
embly language, meaning that in general the programmer must do some manipu-
lations to get certain effects. C is very close to assembly and Think C is
provided with a (hopefully complete) library of toolbox calls, global variables
and structure definitions. The field you ask for is possible to define in C
but was apparantly left out.

BTW, 5.0.3 updater is available via annonymous ftp from Sumex-aim.stanford.edu.

first, some generalitys.

macintosh programs have to be able to function on b/w and greyscale monitors,
color should not be a prerequisite for the general application.

Also, while the TCL is an application framework, it is not a total substitute
for the OS, which keeps it lean and mean.  You see this in the Bartender class,
where the bartender only supplys access methods which involve the data it
maintains in parrallel with the OS menumanager.  Wait for Bedrock, if you want
that much glue inserted between your ap and the native hardware.

now to the specific.

The documentation for color under system 6 is in IM-5, and is modified by IM-6
to reflect system 7 changes, and amplified by certain TN.  For controls, you
should read about the control manager, and also color quickdraw.  The standard
contol procs will colorize themselves via custom color table resources, or you
can author your own control procs (lotsa luck on this one).

Colorized standard controls should come for free in TCL, the OS should handle
all of that for you.  You'll use ResEdit (Resourcerer, SARez, whatever) to make
the appropriate routines, and have your program use color windows wherever
possible (I think CWindow does that automatically, but you should check IWindow
just to make sure).

Now if you want to provide a programmaticly controled appearance, that is
entirely up to you, as neither the TCL, nor the OS have any direct support.

Be warned, that direct manipulation of color behind the users back is often
considered a fiendly action by users, especially color-blind ones.  Also, the OS
has to moderate a shared resource between all active processes, namely the color
tables of the monitor, and thus the actual colors available to your app may not
be stable, especially if your user is running superpaint or photoshop against
your app.

Hope this helps,

I beg to differ, I've been programming Lisp & CLOS for years now and
they're much less like assembler. C of course, is much more like assembler
than most other languages which is why it has a certain utility.

is there a way of filtering out only command keys?  even if i lose stdin
that would be ok. (i'm only using the console for printf stuff because
it seems so painful to try and output c stuff using pascal toolbox
routines.)

any ideas?  thanks in advance.

I'm sending this out on the ThinkC net because I figure that some of you
are crazy enough to be as touched by this as I was.  If not, just disregard
it as programming overload.

Yesterday, after very little sleep and a day of trying to get PenPoint
to do serial I/O on a PC (my first mistake), I went to a local fast food
place to grab a quick bite.  I met a retarded adult who was attracted to
my car by its KCRW bumper sticker (Santa Monica NPR radio station).  It turns
out this guy lives by himself and is an avid radio bumper sticker freak.
He is kind, gentle, and very enthusiastic and I guess I was touched by
the utter simplicity of his existence, the sole goal of which is to collect
radio bumper stickers.  Unfortunately, he has never left St. Louis and has no
living family so he is limited to bumper stickers from St. Louis radio
stations.  I can't possibly convey in words his fascination and obsession
with my KCRW sticker, which, unfortunately, is permanently bonded to my bumper.

So.....  I am asking any of you out there who have have an extra minute and
want to do something incredibly nice for a guy who has incredibly little
going for him in most arenas.  If you would drop a bumper sticker from your
favorite local radio station in the mail to me, I will pass it on to him.
He gave me his name and address and wrote, in the printing of a child,
'loves radio and tv stickers.'

If you are so inclined, send a bumper sticker (or stickers) to me at the
address below.  I promise that you karmic bank account balance will increase
substantially for this small act.

Thanks
