The Comp.Sys.Mac.Programmer Digest is moderated by Mark Aiken
([e-mail]).

The digest is a collection of article threads from the internet
newsgroups comp.sys.mac.programmer.help, csmp.tools, csmp.misc and
csmp.games. It is designed for people who read news 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
may still be able to post messages to the group by using a mail server
like anon.penet.fi (mail [e-mail] for more information).

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
ee.mcgill.ca).  Article threads are not added to the digest until the last
article added to the thread is at least two weeks 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 digests can be obtained by email, ftp or through the World Wide Web.

Subject: Best way to support music?
Date: 25 Nov 1996 03:39:13 GMT
Organization: University of Pennsylvania

I'm writing an application where it would be appropriate for the user to
import some kind of music file created by another application and play it.
What would be the least-effort, most effective way to do this?

Would the MOD format be a good one to support?  I know that it used to be
possible to use the music-synthesizing code resources from Sound Trecker
for this purpose, although I can't find the interface or documentation for
any recent version of those resources.

What could QuickTime do for me?  Other than movies, it does provide some
kind of support for real-time music synthesis, doesn't it?  Can I easily
use imported MIDI data with QuickTime?  Which manual should I RTFM?

Thanks.

     Check out PlayerPro 4.5.3 Demo available all over the web.  (I found
at the MIT Hyperarchive)  It uses the same MOD format familiar from the
old Amiga days, still an _extremely_ popular format for in-program music.
It supports four voices, and the format is extremely simple.  I'm unsure
whether PlayerPro's docs cover the MOD format, but docs are Certainly
Available from those Amiga people!

     I used MODs awhile ago and enjoyed the ease and portability of both
the format and the player.  The current Mac version supports QT
instruments and samples, and gives insight into the workings of Mac
sound.  The demo version also includes a fully functional sound editor you
might find useful, though the interface is -quirky-.  Cut, amplify, echo,
and all that are in there, faster than SoundHack, more stable than
SampleEditor.

Look for PlayerPro and its developer's kit. Last time I checked, you could
use the PlayerPro libraries in your programs for no charge, and the
package was well supported with updates.

I, too, really want to be able to use MODs in my programs.

I also found the SoundTrecker libraries on InfoMac, but they are really
old and don't support CodeWarrior.. they only support THINK.

Does anyone know of any method to get a new version on these
SoundTrecker libraries?

[Summary: Someone else and I both wanted to find a newer version of the
Sound Trecker API that would work with CodeWarrior, and Karl mentioned
PlayerPro.]

Thanks, Karl!  I got it off of InfoMac.  The player is pretty dam'd
expensive for shareware,

but the API is 100% free for any use!

I find that really impressive.  It's in CodeWarrior format, too!  Thanks

The PlayerPro libraries are good and free. If you want to manipulate the
music files, you will need the PlayerPro application which is shareware,
although I believe the fee is a ridiculous $100 or thereabouts. I paid
before he put the price up. This stuff should all be on info-mac.
Apologies if the price is not correct.

I notice that in the Mac Warehouse catalog, the price of Codewarrior is
more than four times the price of Symantec C++.  What is the difference
between these two compilers?  Is Codewarrior really more than four times
better?

I've been a long time user of the THINK C product which was bought by Symantec
years ago. I've developed shrinkwrap with it for some well know companies.
It's a very professional tool set. IMHO the IDE is still ahead of CodeWarrior.

HOWEVER I no longer use it because of Symantec's long standing lack of support,
lack of continued development and arrogantly unresponsive attitude.

With all its warts, some of which will disappear in time I'm sure, CodwWarrior
(and ETO) are the professional tools I use these days on a daily basis.

The most impressive things about Metrowerks are:
(0) They listen AND respond to their customers
(1) They listen AND respond to their customers
(2) They listen AND respond to their customers

The major weakness' in their IDE (versus Symantec) imho:
(0) no ability to have multiple projects open simultaneously
(1) no ability to nest projects (great for doing builds)
(2) mildly less mature compiler

A major strength is the PowerPlant framework/class library which is pretty well
the best thing since sliced bread.

Sad as I am to see Symantec repeatedly dropping the ball I am thankful that Metrowerks
is there to pick it up and score.

Go with CodeWarrior... you'll not regret it.

Well, I'm not sure what the Symantec package includes, but with
Codewarrior you get C/C++, Pascal and Java language support.  For
platforms, you get 68k, PPC, Windows (95/NT), Magic Cap and BeOS.  Once
you pay $399, its only $199 per year after that to renew your
subscription.

Simple answer would be "no", but really it depends on what you are
doing. If you are interested in learning C++ or doing some programming
in your spare time than either environment will probably do you fine. If
you have special needs (want to write Windows, Magic Cap, or BE (this
may be all of us soon)) you should go with CodeWarrior, since Symantec
does not provide solutions for this. In either case I'd suggest looking
at both products.

So when will Visual Cafe Mac be released? The PR1 release is barely useable
right now. It takes several minutes just to change a component name on my
PowerMac 8100, and the debugger is far too limitedbe useful. I have taken
to laying out a screen in Visual Cafe, and then using Codewarrior 10 to
edit and debug the code!

Visual Cafe will be released REAL SOON NOW. That's exactly what I've
been told to say so as to not give our competition any hints as to the
date. But if I was to hint at it, and I'm certain our competition could
guess at this (so I'm not giving anything away), we would probably want
our launch to be at a big mac event early in the year.

Typing performance problems? Yep we had em. They will be fixed in the
release. As for the debugger, we have made some additions (watch window)
and it is now pretty stable and fast, but is there anything in
particular we're missing. Run into anything else annoying?

Appreciate the feedback!

Hey I don't feel anger...I'm not paid to run Symantec. This is about the tools of our trade.

As the new artisans and craftspeople we choose what for us are the best tools.
Symantec, Metrowerks, Appmaker,  and for that matter a renewed Apple MPW team,
provide us with them.

I just periodically go shopping for nifty new tools to make my life easier.

Symantec management would appear to continue to suffer from severe rectal myopia.
Their *engineers* have done a great job...and many of the great ones have moved on to
more fertile environments. Many of them are still there.

However personally speaking I no longer expect, based on the evidence, to see any sustained
effort on Symantec's part to support and enhance their IDE. They are all chanting the Java
mantra these days.

Fortunately or unfortunately that is not the arena in which I need tools.

Just my 0.02¢.

Mick and others have reported the straight story on this--CW support is
tremendous. I use Sym, CW, & MPW. One thing Metrowerks has done to Sym
is to get them going in the right direction in some ways. I hope that
they continue to boost up their SW and support so that we'll continue to

-make a .SYM(using CW) file and .dsi file(just a text file) containing

It's THE debugger to use debugging code resources, esp. ones that have code
that runs at interrupt time (like completion routines).

Well this is a tough one.
If your INIT patches a trap then there's no way I know of to reinstall it
without rebooting.
Here's some things I use:
Ä Work on 2 machines. Debugging an INIT on the same machine is a pain :-)
Ä Write your own DebugStr routine - here's the one I use:

void DebugMessage(Str255 p, short errNo)

{
  Str63 errstr;

  if(errNo==0)
     DebugStr(p);
      else
       {
        DebugStr(p);
        NumToString(errNo,errstr);
        DebugStr(errstr);
        }

  }


Ä Call this routine in strategic places, i.e. before and after patching the
trap, in the patch, and in error checking. The good thing about it is that
you can control the flow,
like :
DebugMessage("\p Entering the function foo() ",0);
and check for errors:
DebugMessage("\pTried to call Bar().Error returned is ",errNo);

Ä Check for errors!
Memory , Resource and File Manager errors should be checked religiously.
Always call MemError() after each memory allocation and ResError() after
each Res Mgr call.
Ä Don't assume anything in an INIT.
You're operating in a very hostile environment :-)
You can't allocate too much memory, you can't get to your globals without
SetCurrentA4()/SetA4(), your resource file is closed, you don't have the
access to the events ( unless it's a JGNE filter)  etc, etc...
Writing an INIT is sorta like sneaking into someone's house in the middle of
the night and trying to do a spring cleaning  :-)

But it's fun:-)

Good luck

HTH, Andy

Are you serious? It's like asking if Microsoft is going to port the
Windows Explorer to the Mac.
DirectX was developed my Microsoft so games makers could access
video(and sound) at the lowest-levels while in Windows. That is why Win
3.1 never had any realtime 3-d games but DOS did. (In DOS programmers
can do whatever they want)

    If you use CodeWarrior you will soon be able to use GameWerks
that will allow you to develop one game that works cross platform.  On
the Mac it uses Game Sprockets and on the PC it uses DirectX.

Actually, Microsoft IS releasing DirectX for the Powermac platform.
I don't know if it's available yet, or how well it performs.
I suppose it will be most useful for the translation of Win95 games to
the Macintosh.

What you could do is CopyBits your image into an old-fashioned 1-bit
grafport (thereby turning all the colors to black-and-white), then use
CalcMask or BitmapToRgn.

If the pict was made with a transparent _CopyBits, you're done.  If not,
draw it into a GWorld and copy the result to the destination.  (Do it in
bands if there isn't enough memory.)

Hey Folks,

I previously posted about StandardPutFile and creating without calling it.
I guess I was vague about what I needed to know.  Basically, I wanted to
know what I had to do in order call FSpCreate(), without having a value in
the systemScript field.  If I call FSMakeFSSpec() with the VolRef and
DirID for the Folder I want; but what do I put in the filename section.
nil??  Then what do I do to create the file with FSpCreate.  If the spec
it returns will work, and my creator ad types. What goes in the ScriptCode
field,  smSystemScript,  What will this name the file.  After this can I
just call FSOpenDF() with this FSSpec And get the correct refnum. I guess
I'm just not clear on what exactly a file spec contains.  Or what's needed
exactly to create a file.

Thanks,

Matt

Nope, you put the name of your scratch file. For instance
"\pMyApp.scratch". Since this is one thing the user should never see, I
think you can safely hard code it into your code...although there's
nothing wrong with storing it in a resource.

Yes.
 > What goes in the ScriptCode

I would think the current script system. I think you can also just put
nil, AFAIK this should get you the Roman script system, which is always
present.

Pretty much what you wrote above. Just supply a filename and you should be OK.

Let me see if I can walk you though it.... (Sorry about the pascal, but my
C is really embarrasingly sloppy)

If I remember correctly you were looking to make a temporary file so...

{First we call FindFolder to get the volume reference number and the
directory ID of the temporary items folder:}

myErr:=FindFolder(kOnSystemDisk,kTemporaryFolderType,true,theVRefNum,theDirID);

{Now we can create the file spec:}

myErr:=FSMakeFSSpec(theVRefNum,theDirID,theFileSpec);

{After the file spec is created we then can create the file.
theCreatorCode is generally the same as the creator type for the
application and theFileType can be pretty much anything you want or need
it to be. ('TEXT" for a text file, etc.):}

myErr:=FSpCreate(theFileSpec,theCreatorCode,theFileType,smSystemScript);

{Once the file is created it can be opened:}

myErr:=FSpOpenDF(theFileSpec,fsRdWrPerm,theFileRefNum);

{Do stuff with theFileSpec here....}

{Make sure to close the file when you are finished with it:}

myErr:=FSClose(theFileRefNum);

{And since it is a temp file it should be deleted:}

myErr:=FSpDelete(theFileSpec);

I hope that helps.....

typedef struct FSSpec

typedef FSSpec   *FSSpecPtr,*FSSpecArrayPtr,**FSSpecHandle;

Say you want to create the file "MyFile", in the directory "Some Dir"
which has the ID 12054 in the disk "My Disk" which has the volume

I am trying to get a FatComponent (QT Data Handler) running on the Mac.

I have built the Code Warrior Example 'FatComponent' and it works.

But, my component does not Open at all with the OpenComponent call.  It
seems that Registration went OK.   Since there are no error codes from
OpenComponent I have no idea why my component is being opened, the
component;'s Open code is not even called.

Are there any Component writers out there?

Your component has to be opened before it can be registered.  When
registering (like at boot time) your dispatch function first calls the open
function, then calls the register function, and then the close function, if
your open function never gets called then either your dispatch function is
messed up or something really strange is happening.

Have you put a DebugStr as the first line of the open function?

If you use the thing command in MacsBug, does your component show up in the
list?

   I am not sure this is true.  It sounds like a chicken and an egg
problem.  I have seen Components
that register other components at boot time.  Some one has to register the
component before it can be called.

   If I use the PPC component I get:

The EntryPoint is from EBBE's deamon seed.  So, I hacked my thing resource
to point only at the 69K version of my component and it registers and runs
fine.  It seems that I am making some mistake in the PPC  coding.

One short reference in  A_Fragment_of_your_Imagination leads me to believe
that the CFM is having trouble with the RoutineDescriptors in the code or
the UPPs.  I removed all of the RoutineDescriptors
and got closer, but the PPC code is still not loading.

A bit more detail:

Make a Get Data event passing 'the selection' in as the direct object.
Returns an object specifier which you can pull apart to find the
selected objects.

Very easy really (afternoon's work at most if you read Greg Anderson's
article - which IMHO is one of the best develop ever published).

If you are not using System 7.5 or later, then forget it. I do know
how to do it in pre 7.5 systems, but it is a totally unsanctioned
and evil hack which I fear to share with the world.

Hi,

You can use the copy/paste feature (scrap manager) with jGNE (a patch to
the MacOS GetNextEvent function).

1. Get an event with jGNE that tell you about a mouse down or/and a key
down.
2. Save the content of the scrap area (in an other buffer).
3. Generate a copy to see if scrap is empty or not. If not, you've get
the name of the interest file/folder. If it's empty, generate a 'return'
keydown event with the PostEvent function; redo the copy and it's now
ok.
4. Restitute the saved scrap buffer to the real one.

Remark : there is surely a best way to do this...

You're darn tootin' there is! I'm not even sure if this would work.
There is no supported way to get the Finder selection in any system
version prior to 7.5 (there is a sneaky, underhand method of vast
and sinister skankiness in earlier versions - it is abstruse in the
extreme).

The way to do it 7.5 is send a Get Selection apple event to the Finder.
Read Greg Anderson's article in develop 21.

KeyMap is now defined as:

unsigned long KeyMap[4]

so by checking myKeyMap[125] you are looking at some long in memory
a loooong way off the end of the Key Map.  ;-)

You'll need to work out which long contains the key you want,
and then check the appropriate bit with something like

if ((myKeyMap[2] & (1 << kArrowKeyByte)) != 0)...

(I made up those numbers).

Matthew,

Here is a function youc an call with the keycode to see
if that key is down:

Boolean
KeyIsDown( UInt16 keyVal ) {
   UInt8 theKeyMap[16];

   ::GetKeys( (UInt32 *)theKeyMap );

   return( (theKeyMap[keyVal >> 3] >> (keyVal & 7)) & 1 );

} // end KeyIsDown

You could alternatively get the same info from the event
record if you are going through an event loop.  If you
have Think Reference or the Inside Mac reference youshould
be able to get what values respond to what keys.

For the up arrow you would call as follows:

     if ( KeyIsDown( 0x7E ) ) {
         // Do something
         }

Hope this helps,
Matt

Right, and for the lazy, the real numbers are:

  myKeyMap[3] in which case the up arrow key is 64.

Of course you probably want the other arrow keys too, but knowing you
should be checking myKeyMap[3] you can easily find those values.

Hi Bill,

the answer is in the Process Manager.

see the routines  GetCurrentProcess(), GetProcessInformation(),
and the ProcessInfoRec structure.

Use PBGetFCBInfo:

    FCBPBRec pBlock;
    OSErr err;

    pBlock.ioNamePtr = nil;
    pBlock.ioVRefNum = 0;
    pBlock.ioRefNum = LMGetCurApRefNum();
    pBlock.ioFCBIndx = 0;
    err = PBGetFCBInfo(&pBlock, false);
    if (err != noErr) {
        /* pBlock.ioFCBVRefNum = vol ref num of dir containing app. */
        /* pBlock.ioFCBParID = dir id of dir containing app. */
    }

I'm not 100% sure about this one, but I've done some similar things.

Use the Process Manager to get Process Information on the current process.
Within this data structure there should be the FSSpec of where the app is
held on disk.

Bill,
other suggestions which have already been made may work as well... here
comes mine:
 1. take the handle to any of your resources (when initializing your
    program, you will probably get a menu handle, for ex.) and call
    HomeResFile (thisHandle) . You'll get the refNum of your program's
    resource file. If you still didn't open other files, you could
    likewise get CurResFile.
 2. Take this refNum and get the FSSpec - if I'm not completely wrong,
    there is a function in MoreFiles which does this. (Sorry, I cannot
    check for the name right here)

May it help,

Roger

This will work, but it's talking to low memory globals, which the
Apple Thought Police say is bad karma. I use GetCurrentProcess()
followed by GetProcessInformation() to do this trick.

something like (off the top of my head)

ProcessSerialNumber     psn;
ProcessInfoRec          pInfo;
FSSpec                  myAppSpec;

GetCurrentProcess(&psn);

// initialise the fields - length of record, pointer to myAppSpec etc.

GetProcessInformation(&psn,&pInfo);

lo,

the following function expects a ptr to an already allocated FSSpec
structure.  when it returns it fills out the FSSpec with data that points
ot your application.  this gives your application name and the disk ID
that its running on and the id of the directory its running in.

//    -------------------------------------------- OurProcessInfo
OSErr
OurProcessInfo(FSSpec    *theFS)
{
    OSErr                    iErr = noErr;
    ProcessSerialNumber        processNumber;
    ProcessInfoRec            processInfo;

    iErr = GetCurrentProcess(&processNumber);
    if (iErr)
        goto bail;

    processInfo.processInfoLength = sizeof(ProcessInfoRec);
    processInfo.processName = NULL;
    processInfo.processAppSpec = theFS;

    iErr = GetProcessInformation(&processNumber, &processInfo);

bail:
    return iErr;
}

I would check out the MoreFiles library for stuff like this. MoreFiles
comes with routines for looping through directories and the files in them
so you don't need to do the work for it. Try Apple's Web site to download
MoreFiles.

I would say it is better to do something like

OSErr  fileErr;
short index=1;
do
  {
  pb.dirInfo.ioDrDirID=dir_id;
  pb.dirInfo.ioFDirIndex=index++;

  fileErr=PBGetCatInfoSync(&pb);

  }while(fileErr==noErr);

since this eleiminates the need to county the files in the first
place. This is a matter of personal taste however.

Richard then mentions methods of tracking directory contents while
stuff is going on underneath - this is a perennial probelm and one which
I solve with linked lists, as he suggests. However, System 7 users
might like to consider the following: using FSSpecs is wasteful since
they take a minimum of 70 bytes even with optimal (memory-wise)
packing. I use file IDs instead. I have routines like the following:

#define kMaxFileIDs 100

typedef struct FileListElem
  {
  struct FileListElemPtr     *next;
  short                      numIDs;
  short                      refNum[kMaxFileIDs];
  long                       fileID[kMaxFileIDs];
  }FileListElem *FileListElemPtr;

In the directory scanning routines I do something like this:
FileListElemPtr    listHead=NULL;

AddListElem(&listHead);

fileErr=PBGetCatInfoSync(&pb);

if((fileErr==noErr)&&((pb.hFileInfo.ioFlAttrib&0x10)==0)) // it's a file
 {
 if(listHead->next.numIDs==kMaxFileIDs)
   AddListElem(&listHead); // add an element to the list

 FSMakeFSSpec(vRefNum,dirID,name,&tempFSS);
 CreateFileID(&tempFSS,&fileID); // function to make a file ID
                                 // and return it
 listHead->next.refNum[listHead->next.numIDs]=vRefNum;
 listHead->next.fileID[listHead->next.numIDs++]=fileID;
 }

You can then do you stuff by iterating through the list. I use arrays
of refNums and fileIDs to cut down on the number of list allocations.

but I don't know how to supply our www address as an argument.
I do know how to send a high-level event with LaunchApplication()
to get an app to open or save a file, but supplying a www address
to Netscape has nothing to do with files.

In Windows this is easy, its just an argument to the app, and the
app uses the old argc, argv[] business.  How do I do the same thing
on the Mac.

Thanks in advance,
Joel

Use the code on <ftp://ftpdev.apple.com> called LaunchWithDoc or read
technote 1002 at <http://devworld.apple.com/dev/technotes/tn/tn1002.html>
which has sample code included.

No sweat.  You need to send an AppleEvent to NetScape.  You want to use
the Get URL AppleEvent (suite id = 'GURL', event id = 'GURL').  If you're
not familiar with AppleEvents, the following code should help.  Error
checking is an exercise left to the reader, as are the MyLaunchApp and
ApplicationIsRunning calls.

8<-------------------------------------------- cut here
OSErr SendURL( Str255 theURL, FSSpec browserFS)
{
    AEAddressDesc        theTargetApp;
    AEDesc                theURLDesc;
    OSErr                err                =
0;
    AppleEvent            aeEvent;
    ProcessSerialNumber    thePSN;

    if ( !ApplicationIsRunning( browserFS, &thePSN))
    {
        err = MyLaunchApp( browserFS, &thePSN);
    }

    err = AECreateDesc( typeProcessSerialNumber, &thePSN, sizeof(
thePSN), &theTargetApp);

    err = AECreateAppleEvent( 'GURL', 'GURL', &theTargetApp,
kAutoGenerateReturnID,

kAnyTransactionID, &aeEvent);
    AEDisposeDesc( &theTargetApp);

    err = AECreateDesc( typeChar, &theURL[1], theURL[0], &theURLDesc);
    err = AEPutParamDesc( &aeEvent, keyDirectObject, &theURLDesc);
    AEDisposeDesc( &theURLDesc);

    err = AESend( &aeEvent, nil, kAENoReply, kAENormalPriority,
kAEDefaultTimeout,nil,nil);
    AEDisposeDesc( &aeEvent);

    return err;
}

If that's all you want to do.. there is NO PROGRAMMING NECESSARY!

Simply save a text file with only the url as its content.

Then edit the creator of the file to 'MOSS', which is Netscape's
creator, and the type to 'URL ' (u-r-l-space).

That's it!  The file is now a Netscape url file.

  When double-clicked, it will lead to you the url!

Ambrosia has this in their two latest games, Avara and Bubble Trouble..
they have files which link to their homepage.

I have an app that launches an program via the Process Manager. I want the
Process Manager to send an 'odoc' Apple Event to the lanuched program. To
do this you send a Data type AppParameters along to the Process Manager
(Page 2-20 Process Manager Reference book Inside Mac). The problem is: How
in the world do you specify the file to be opened in the messageBuffer of
the AppParameters data type. I've tried passing an AEDesclist in there,
but that doesn't work. Any suggestions where I can look. I'm getting a
blister on my thumb, thumbing through Inside Mac. The only thing I can
find is on 2-21 in Process Manager Reference. Is says: The nature of this
data varies accourding to the event being sent. That's not much help!

Oh, but you got soooo close. What you need to do is build an 'odoc' Apple
event, specifying the Finder as the target, and the document to be opened
as the direct parameter, the pass this as the appParameter.

As has already been stated, see tech note 1002 for the details

Apple has a "code snippet" for this, named LaunchWithDoc.  You can find it
on developer CDs, or on the web site.

Almost, but not quite. You forgot one crucial step:

After you create the 'odoc' event with the Finder as the target, and the
document as the direct parameter, you need to call "AECoerceDesc" to a
"typeAppParameters" Apple Event descriptor. The data handle of that Apple
Event can then be used for the AppParamters flag.

P.S. - I'm not sure if the actual type is "typeAppParameters" but it is
something close. Again, all the details are in technote 1002.

Given an application's 4-character signature, is there any way to launch

It appears that to use PBDTGetAPPLSync I need to know what volume the
application is on. LaunchWithDoc2 (in Snippets) does a bunch of looping...
is this the only approach?

Not that I know of.  You can tell the Finder to launch an application
given an FSSpec, though.

Directly?  No, not really.  I've got a LaunchBySignature routine, but it

Install a CFM Termination routine. In MW look in the Linker
pref panel (I think). Type in the name of the routine that you
want called when your app exits.

You can use the CFM Termination routine to do what an ExitToShell patch
would do for non-CFM 68K code. Otherwise, you just need to create a
RoutineDescriptor to your patched ExitToShell instead of passing just a
ProcPtr to SetToolTrapAddress.

"The Client/Server Toolkit for C and C++ Programmers"
New Book From NobleNet Turns Programmers Into Client/Server Experts

New York, October 8, 1996 --  NobleNet, Inc. today announced the availability
of its newly published book that turns C and C++ programmers into
client/server experts.   Co-authored by middleware experts Steven Lemmo and
Rich Grehan, The Client/Server Toolkit for C and C++ Programmers  is a self-
contained instructional tool that teaches programmers how to distribute any
application or Application Programming Interface (API) across a network.

The CD-ROM software included with The Client/Server Toolkit features a unique
Windows-based client/server simulator that lets programmers gain hands-on
experience in client/server partitioning.  Programmers are guided through four
"real-world" client/server projects: distributed ODBC database, scanner
device, image engine, and datafeed.  The authors expertise combined with a
Rapid Application Development (RAD) environment, demystifies the art of
distributing complex applications.

"I learned more about client/server development in the last three days of
reading your book than I learned in the past few years of doing C and C++
programming," said Pascal Specht, Technical Sales Engineer at Precision
Software in Paris, France.

"Our new book will help any C or C++ programmer that wants to learn about
state-of-the-art client/server computing," said Steve Lemmo, co-author and
Chief Technology Officer of NobleNet.  "The techniques taught in the book will
help programmers learn to use the powerful Interface Definition Languages
(IDLs) found in today's most popular distributed computing middleware."
Beginning with a monolithic application, readers learn how to separate
programs into independent parts that communicate with each other.  While other
books on client/server computing include sample code, The Client/Server
Toolkit goes further and delivers a true client/server Software Development
Toolkit (SDK) designed for application partitioning.  Unlike other approaches,
programmers learn to build client/server applications using industry-standard
RPC technology that requires no source code changes.

"The Client/Server Toolkit is ideal for programmers that want to get a quick
immersion into client/server computing with tools that require very little
effort to learn,"  said Vincent Russo, Assistant Professor of Computer Science
at Purdue University.  "I like the fact that the book is totally self-
contained.  It has a wealth of real-world examples that provide the reader
with a thorough understanding of client/server development.  And the simulator
gives programmers hands-on experience with building and running real
client/server applications."

Although The Client/Server Toolkit is written for C and C++ programmers,
examples are given that show "drag and drop" programmers how to create
client/server applications utilizing popular GUI front-ends such as Visual
Basic, PowerBuilder, Delphi, and Developer 2000.  Distributed with the book is
a free version of NobleNet's powerful standards-based RPC product used by
client/server developers world-wide.  Programmers are presented with client
and server Windows connected by a simulated network.  Using NobleNet RPC,
applications developed on the simulator are easily deployed to over 40
platforms including 26 UNIXes, Windows 3.1, 95, and NT, NetWare, Macintosh,
OS/2, and VMS.  More than 20 Windows-based TCP/IP stacks are supported to
ensure operation in existing multi-vendor environments.

Co-author Steven Lemmo founded NobleNet, engineered NobleNet's first software
product, EZ-RPC(R), and led the team that developed the company's NetWare and
Windows-based middleware tools.  With an in-depth understanding of both
communication and application software, he is a sought after consultant on RPC
programming.  Steve has over fifteen years of experience in software
engineering and tools development in companies such as Computervision Corp.,
Sun Microsystems, Inc., and Xerox Imaging Systems, Inc.  He is widely
recognized as an expert on distributed computing and is frequently called upon
to appear at industry forums.

Co-author Rick Grehan has been on the editorial staff of BYTE Magazine for
over 11 years.  He is currently the Technical Director of BYTE Labs and the
author of BYTE's monthly CodeTalk column.  His articles have appeared in BYTE,
Embedded Systems Programming, and Forth Dimensions.  In addition, he was a
contributor to the 1993 edition of The Encyclopedia of Microcomputers,
published by Marcel Dekker, Inc.  Rick is also the designer of BYTE Magazine's
BYTEmark benchmark suite.

The Client/Server Toolkit for C and C++ Programmers is published by NobleNet.
The 350 page book with CD-ROM can be ordered for $49.95 by calling (800)-250-
6427 or (508)-893-0398.

NobleNet offers tools for distributed client/server development for procedural
and object paradigms. Incorporated in 1991, NobleNet is a world leader in
Remote Procedure Call (RPC) technology and has won numerous awards for its RPC
product family.   NobleNet also distributes IONA Technologies' industry-

Yes I know, but Shutdown Items only opens the file in the application that

     You might be able to do something with the "Shutdown Items"
       items folder in the system.  Simplest solution would be
       to include a graphic document in that folder with the

So write a little Applescript that displays a picture for a few seconds,
then exits.  To display the picture, I think you could use
GraphicConverter, JPEGview, clip2gif, etc.  Put the Applescript in your
Shutdown Items folder once you've got it working.

Firstly your signature is bigger than your message!

The process Manager will do the job for you.

You want to call GetCurrentProcess to find your own Process Serial Number
, then SetFrontProcess passing the Process Serial Number returned.


Dave

ie,

OSErr iErr;
ProcessSerialNumber PSN;


iErr = GetCurrentProcess(&PSN);

iErr = SetFrontProcess(&PSN);

/*add error handling*/

You may like to check if you are the front process by calling:
iErr = GetFrontProcess(&PSN);
and comparing it against your process serial number using _SameProcess
OSErr iErr;
ProcessSerialNumber PSN,PSN2;
Boolean result;

iErr = SameProcess(&PSN,&PSN2,&result);

The result is a Boolean.
You must use SameProcess to compare two processes, the interpretation of
the bits in the process serial number is internal to the process manager.

  A couple of gotcha's..
  Note that SetFrontProcess() is a request to send to the front. You aren't
  in the front when it returns, and you may not come to the front at all !

Anybody have any source for such a task?  Perhaps even some pointers in

Check out the updated Color Gamma library which can fade a monitor at any
depth to a given color. Demo and source are available at Info-Mac and other
archives:

You need to use a gamma fade. There is code on the net; do a search for
"gamma fade". The source I've seen is in Pascal.

Try this:

#define BACKWARDS_HALF_SPEED       0xFFFF8000 // reverse, 1/2 speed
#define BACKWARDS_1_SPEED          0xFFFF0000 // reverse, normal speed
#define BACKWARDS_2_SPEED          0xFFFE0000 // reverse, 2X speed

// some variables...
Movie gMoviel;
MovieController gController;
....
// later in your code, when you want to play
// an opened movie backwards, do this:
ComponentResult  result;
// play backwards at normal speed
result = MCDoAction( gController, mcActionPlay, (Ptr)BACKWARDS_1_SPEED);

Hope that helps,

Heres how is MCDoAction: (in C)

MCDoAction( theController, X, (Ptr)True );

X =   0xFFFF8000 back half speed
      0xFFFF0000 back normal
      0xFFFE0000 back double speed

or sometthing like this. Or while the movie's open shift double click the movie.

Hi all!

I know how to show/hide the menu bar with my own code, but I remember

like a part of QuickTime 2.1 or something.

Any information on this? (docs, what headers, prototypes, minimal system

John,

Maybe what you're referring to is one of the QuickTime samples, a
MovieController component written by John Wang in Apple DTS. The
MovieController inherits everything from the standard MovieController
component but also lets you hit the tab key to play back full-screen
with no menu bar. Check out the source code to this sample.

Another approach might be to use the DrawSprocket, but depending on what
you're doing this might be overkill, and it only runs on PowerPC.

BeginFullScreen and EndFullScreen were introduced with QuickTime 2.1.
When your code is bracketed by these calls, QuickTime will hide the
menubar, clear the screen corners, and create a background color matte if
necessary.

These functions are documented in the QuickTime 2.1 developer note which
is available on the Internet at:

<ftp://ftpdev.info.apple.com/Developer_Services/Development_Kits/QuickTime/Programming_Stuff/QT_2.1_for_Developers.sit.hqx>

Actually QuickTime has calls specifically for this.


Check in Movies.h QT header.  These will auto-resize a multisync monitor to
display a smaller image if you want as well. Check out the flags in the
same file.

You can only tell if your process is the front-most process. Basically you
call GetCurrentProcess and GetFrontProcess and compare the two
ProcessSerialNumbers.

But there is no way to tell if your program is hidden. Only the System
know that, and it's not telling.

No, there must be a way. In Script Editor, we can find out
the value of property 'visible' of object 'application process'.
That means sending an appropriate Apple Event to Finder (or compiling
and executing a script from within the application). But I believe
there is something less complicated.

Subject: [Q] Useful error messages?
Date: 7 Dec 1996 18:10:41 GMT
Organization: University of Texas at Austin

Currently, whenever my program encounters an error as the result of a
toolbox call, it will call an error handler with the result code of the
call. For example, a missing resource will result in the handler
displaying a dialog:

Sorry, a fatal error occurred.
System error: Unknown error (ID -192)

How do I make my code display more informative messages, like

Sorry, a fatal error occured.
System error: Resource not found (-192)

There must be a way of doing this, since I see alerts like this in the
system software and in other programs. Considering the number of errors
that one can potentially get, I find it unlikely that every program is
expected to know the meaning of all these and include appropriate English
error messages. Using CW10, in case this is in a header file somewhere.

Any hints on how to do this will be very welcome.

Thanks,
-Stian

The way my application currently works is to tell the user:

Sorry, a fatal error has occurred:
Wrong password (internal error ID = 5)
[Quit]

for system errors, it currently says:

Sorry, a fatal error has occurred:
Unknown error (system error ID = -192)

The ID number in the case of system errors is obtained either by a call to
ResError(), QDError() or whatever is appropriate, or simply as the return
value from a toolbox call.

In this project, 90% of the code is for handling things like multitasking,
Apple Events, window updates, errors, etc ad nauseum. My next project will
probably be to write a tiny application shell for use in future projects.
(I know that many already exist, but I think I want to write my own to
keep it lean and small.)

For now, I guess my users will just have to put up with Unknown errors.
Most such errors are handled internally in my application before they ever
reach the error handler, so a missing resource would most likely result in

Sorry, a fatal error has occurred:
AccessMaster has been tampered with (internal error ID = 8)
[Quit]

So hopefully, system errors shouldn't show up too often. And if they do,
hey, it'll be freeware - you get what you pay for ;-)

I've seen a publicly available set of STR# resources with strings for
the most
common type of error you get in a Mac app.  The index of the string
corresponds
to the error number, so it should be as easy as...

void DoError( OSErr inErr ) {
    Str255 errStr;
    GetIndString( errStr, myErrorStrings, inErr );
    ParamText( errStr, "\p", "\p", "\p" ); // or whatever
    Alert( myAlertRsrcID ); // Not sure of the exact form of this call...
}

Search the info-mac site for these resources...

Hi,

 Isn't it possible to use <errno.h> and <string.h>  to be able
to call strerror() ? and thus get the text that goes with the error???
