I tried everything I can think of but I can't get THINK Pascal 4 to:

   1 Wordwrap the Text window, or

   2 READ a char or integer without a CR to mark end of input

I've tried TP4 and TP4.01 on IIsi and SE machines with System 6.0.5 and
7.0.1 (with TuneUp 1.1.1) and INITS on and off.

Any WRITE or WRITELN with a parameter wider than the Text window writes the
whole parameter (which can be checked by zooming the Text window) but simply
continues it out of view under and to the right of the scroll bar. Also, a
WRITE leaves the cursor immediately to the left of the scroll bar,
effectively in the middle of the output.

More seriously, a READ statement waits for a CR before processing any input.
The problem, of course, is that this can easily leave the CR (converted to
a space) in the input stream waiting for the next unsuspecting READ/READLN.

Has anyone else found these problems? Am I imagining them? Am I missing
something? Are there controls or workarounds for these problems? Are these
'features' and not bugs?

These are standard problems with Pascal.  If you want to do anything more
fancy than single line IO you have to go to the OS.  In this case, that's
the toolbox and the Window Manager.  You could use TextEdit if you were
inclined, but the gist is that it's a limitation of Pascal.

I had to write a lot of custom VMS IO routines to do real time games in Pascal
while I was in college.  It's not fun, but it's not that hard either.  The
simplest thing is to write a real Macintosh application using the THINK Class
Library.  Of course, that's just one more learning curve to climb.

Subject: PlotIconID - Why are my icons B&W?
Organization: Qualcomm Incorporated
Date: Mon, 1 Jun 1992 01:26:44 GMT

I'm trying to use System 7's handy PlotIconID function to display small
color icons in a dialog box, but the icons always appear black & white.
There are two places I'm attempting to plot the icons in the dialog:
a user item, and within an LDEF.  I should also note that the dialog itself
is being tossed about via SFPGetFile and extensions I've made to standard
get file.

All my icon resources are defined, the destination Rect for each icon is
16 x 16 pixels, and I am able to draw color pictures in the dialog... but
no color icons.

Any insight ino this problem?

Thanks!!

You need to create a 'dctb' resource for your Dialog. Set all
   of the fields to the default (black or white, as appropriate).
   When you load the dialog, it is now smart enough to make it a
   Color Grafport.
If you have problems, you can mail me and I'll drop a binhex
   Resedit file with the above resource. WARNING: The dialog
   editor in ResEdit 2.x has been known to die horribly. You
   should only create/modify copies of your resource file, and
   copy them across later. (This is from experience!!!)

Sounds like your not calling "GetNewCDialog" but rather the old B & W
version of the call...

Don't ask *ME* why, but you can draw color pictures in grafports using
DrawPicture, but you can't plot color icons that way. You need to have a
Cgrafport setup...

You use a custom DITL. You should create a 'dctb' resourcce for that DITL so
that the Dialog Manager calls made by the Standard File package result in
color grafports. I'm told that an empty 'dctb' can be made, and I would
vote that that's the way to go, otherwise, do as ResEdit does, and have a
wierd color for the Title color entry (which is unused in Standard File).

My assumption is that the Icon Utilities stuff checks the grafport. I could
be wrong. An indicator that you need a 'dctb' is if the gray text in the
buttons is dithered instead of true gray. The button controls draw in the
grafport, whereas the window frames and scroll bars are drawn in the window
manager port.

I had the rather bizarre situation in a MacApp program that PlotIconID /
PlotIconHandle would plot a cicn, rather than the claimed ic?? family. So until
I made a cicn I had b/w icons being plotted.

Subject: Quadra, SFPGetFile, Bus Error = HELP!
Organization: Simon Fraser University
Date: Fri, 29 May 1992 19:50:27 GMT

Hi,

I have just started fooling around with macintosh programing (as opposed
to using the mac to write ANSI C code for research).  Here is my problem:

I am playing with the TinyEdit application in THINK C 5.02 trying to find
out why an error is occuring.  I have narrowed it down to the following
scenario.

I have declared a ChooseFile routine in the CEditApp which overrides the
one in CApplication.  If I make it exactly the same, of course it works
fine.  Then I use ResEdit to copy the standard dialog resource (id=-4000)
into my TinyEdit resource file, and give it an id of 128 (I have tried
many different id and get the same problem).

Now I modify the code so that it calls SFPGetFile with my new id (128).
Since the resource is exactly the same as the copied standard one (-4000)
I expect that it should all work fine, but instead I get a bus error. I
have reason to believe that this is only happening on Quadras, and it
happens with or without the cache switch on.  Here is the code snippet -
can anyone help?

Thanks,
Peter



void CEditApp::ChooseFile( SFReply *macSFReply)
{
   Point      corner;
   Boolean    wasLocked;
   short      id;

   id = 128; /* this is my copy of resource -4000 */
                                        /* Center dialog box on the screen    */
   FindDlogPosition('DLOG', id, &corner);

   wasLocked = Lock( TRUE);

   SFPGetFile(corner, "\p", sfFileFilter, sfNumTypes, sfFileTypes,
              sfGetDLOGHook, macSFReply, id, sfGetDLOGFilter);

   Lock( wasLocked);
}

My first wild guess is Boomerang, or some other Standard File patcher.  I had
some problems with my Quadra and Standard File for a while.  I am now running
Super Boomerang 3.02 and not having any trouble.

Of course, it could be something completely different.

I would also like to hear from you.  I am the Apple Events Registrar.  It is
my job to preach the gospel of standard Apple Events, discourage the use of
profane and blasphemous AE, keep the holy list of constants and arbitrate the
conflicts therein.

I am an advocate of the object model and will speak of it on any occasion.

ideals, but I've been known to stray by the wayside (typically after a few
beers ;).

Yes, I know.  This is probably the stupidest question ever asked, but I need to
know:  How do I open the data fork of a file whos resource fork is already open?

Basically, I am writing an INIT that needs to read from its data fork.  How can
I get to it?  All of the file accessing stuff that I can find needs to have the
name and volume reference number or whatever.  But if the resource fork is
already open (it has the INIT code and other resources), how can I get at the
data fork?

Call PBGetFCBInfo() to get the name, vRefNum and dirID of the resource fork,
which you can then pass to one of the Open calls to open the data fork.  In
C, and using FSSpecs:

    FCBPBRec    fcbpb;
    FSSpec      fss;

    fcbpb.ioNamePtr = (void *) fss.name;
    fcbpb.ioVRefNum = 0;
    fcbpb.ioRefNum = CurResFile();
    fcbpb.ioFCBIndx = 0;

    if (PBGetFCBInfoSync(&fcbpb) == noErr) {
        fss.vRefNum = fcbpb.ioVRefNum;
        fss.parID = fcbpb.ioFCBParID;
    }

The problem is, I want to send an AppleEvent to another program
running on my machine, that I launched.  I get the ProcessInfoRec
using the process serial number returned in the launchParamBlockRec
structure.  Using the following I set up the target address,
insert some other information and send the event.  AESend() returns
- -903 (noPortErr - Unable to open port or bad portRefNum).  I
get the same error if I use the code inside the 'notdef'.
I've turned on "program linking" from the "Sharing Setup" control
panel, though I don't think it has any thing to do with it.

BTW, noPortErr is not mentioned as a possible result code at
the bottom of the AESend() section.

Every time I've received this error number, it's because I was trying to send an
AppleEvent from a non-AppleEvent application. For instance, I once tried writing
an MPW tool that told the Finder to quit. Under MPW 3.2, I'd get this error, but
it would work under MPW 3.3a9. In another program I wrote, I forgot to set the
High-level Event Aware bit in the SIZE resource, and was getting that error
number until I set the bit.

Make sure that both programs have the "high level event aware" flag set  in the
'SIZE' resource.  I had experienced the same problems you've mentioned, when
I realized I'd never created a 'SIZE' resource for the app sending the Apple
event.  After creating the resource and setting the correct flags, everything
worked fine.

Remember that both apps have to be high level event aware.

b) signal my application when the command key is hit.

The second I can deal with.  But displaying the special shift and option

This may or may not solve your problem, but I've got an MDEF that
supports all of the modifier-key alternatives. I also have the pascal
code to solve #2 for you.

It currently has one drawback: it uses the icon field of the MENU
resource to indicate which modifier keys to match against, so you can't
use icons in your menus.

I recently discovered that these special MDEFs used by many popular
applications also assume that they should use Chicago 12 for drawing.

Use TextFont(0) and TextSize(0). You'll get the correct results for any

Subject: Background Printing Question?
Organization: University of Tennessee
Date: Mon, 1 Jun 1992 18:09:01 GMT

For some reason when my program goes to print it will not recognize
that BackGround Printing is turned on.

thePrRecHandle^^.prJob.bJDocLoop is always 0 for draft printing even
though the file is saved to disk and then printed by PrintMonitor.

Is there another way to determine whether or not background printing
is turned on?  Any ideas?

Danny McCampbell

PS  If background printing is on, I was just wanting to let users
know the file was being saved to disk and would be printed in the
background.

I posted this once before but I am not sure it went through so I am posting
it again.

I am checking to see if thePrRecHandle^^.prJob.bJDocLoop = bSpoolLoop
so I can bring up a dialog telling the user that the file will be saved
to disk and then printed in the background.

Unfortunately the result always is 0 for draft printing although if
background printing is turned on it spools the job anyway and prints
fine.

Can anyone help me out on why this is happening.  Is there something
else I need to check for to see if background printing is turned on?

Thanks in advance.

It won't work, because bJDocLoop is a vestige from the days when the only kind
of printer was the ImageWriter.  It only tells you whether you are supposed to
call PrPicFile, in the case where a) the printer is an ImageWriter and b) it is
using the ImageWriter-specific spooling mechanism.

The background printing mechanism introduced with MultiFinder is completely
different, and does not require you to call PrPicFile.  That's why it always
tells you it's doing "draft printing."

> Can anyone help me out on why this is happening.  Is there something

There's nothing provided by the printing code to tell you this.  You might be
able to find a hack, but it would be unsupported.

I want to attempt to read 3.5 in diskettes from my Ensoniq synthesizer
in the Mac. I know that this can be done on PCs, but the address marks
and everything else on the diskettes make them look too foregn for the
Mac.

Is there information on reading non-Apple diskettes available? Surely
the same problem occurs with PC diskettes,and Sun diskettes, but both
formats have been cracked by various programmers.

I have a II fx if that makes any difference.

If the physical format of the disks is the same as PC disks, then the Mac
can read the raw data from the disks, however it can't necessarily interpret
what all the data means (i.e., files, directories) unless someone has written
some software to convert the information on an Ensoniq disk into something
that the Mac recognizes...

Please note that there are a least two issues
1.  Getting the mac hardware to read the diskettes as well as telling you
    what has been read,including separating adress marks and data.
2.  If nescessary, transform what you have read ino meaningful information
    the mac can use.

In the case of PC diskettes only issue 2 needs to be dealt with as a mac
with a superdrive has readily bult in routines that do everything else for you.
You simply request a certain block number to be read, and the built in driver
will do it.

In the case of Ensonique diskettes you also has to deal with issue 1.
(Ensonique diskettes have much in common to PC diskettes but uses 10 sectors
 pr. track numbered in the tagmarks as Track 0 to 9, whereas MS-DOS uses
 9 sectors numbered from 1 to 9)

Since you have a IIfx, you should be able to make a device driver control
call to the driver giving you the raw data. In the Tecnical Note 272 is
described the call "Diagnostic Raw Track Dump (csCode=18244)".  This is
not supported on all Macs and for those not one has to find other ways to
read the raw data.

This should solve the problem for you, but not for the rest of us.
(I have found that a PC is the next best solution.
It can easily be set up to read Ensonique diskettes)

This may be a silly question but:
I am putting some buttons on my window and SICNs are about the right size.
what I need to know is how to draw them from the resource fork to the

in a different form than in the SICN resource.  I know I could convert this

The THINK Class Library has a number of utility routines that are of

TBUtilities.c for more information (I don't want to post their code).

See Technote #252: "Plotting Small Icons" (which shows the copybits method) or
#306, which talks about 7.0's icon plotting routines.

What is the best way to draw a button in a window?  I'm currently
drawing it with QD, and hiliting it, unhiliting it, etc when checking
for mousedown in the button's rect.  My problem currently is, how do I get
the button to unhilite when the cursor leaves the rect, but still in
a mousedown?  I'd love to hear that there is a way to easily create a button
in a window like in a dialog, but I can't find any reference
to it in IM.  Any suggestions?

Thanx,

<< What is the best way to draw a button in a window? >>

Depending on how much of a window this is, you may want to use a DLOG/DITL
and simply treat it as a normal window. This will give you automatic
button handling (ie: via IsDialogEvent(), etc.)

You can add controls to any window using NewControl/GetNewControl.
When you get mouseDowns in your window use FindControl to
determine which control, if any the mouseDown occurred in.

Read the Control Manager section in IM Vol 1 for detailed information.

Subject: vdig component for DigiVideo (Q)
Organization: University of Tasmania, Australia
Date: Wed, 3 Jun 1992 05:25:47 GMT

I am attempting to use the DigiVideo vdig component that was on the
beta QuickTime CD. The DigiVideo card was manufactured by AAPS, later taken
up by Sequel Development.

Does anyone know if there is an updated version available (perhaps on the
release QT Development CD)?

My specific interest is to switch the vdig component into a mode where
it grabs greyscale images rather than colour (our camera is B&W).
I am expecting to do this using VDSetInputColorSpaceMode; I assume if I am using
the sequence grabber to drive the vdig I can
coerce the result of ComponentInstance SGGetVideoDigitizerComponent(SGChannel c)
to a VideoDigitizerThing (am I right in thinking they refer to the same object?).

Having posted this question directly to Sequel via AppleLink without response
(are they still in business?) and to the QuickTime discussion folders
on AppleLink also without response, perhaps the Internet community
has the answer.

Any suggestions/comments appreciated.

I'm not familiar with this video card, but what happens if you call
VDSetPlayThruDestination and specify a pixmap from an eight-bit greyscale
offscreen GWorld? Would that work?

Another trick that may work with cards that don't autosense NTSC/PAL mode
(it certainly works with our Moonraker) is to call VDSetInputStandard and
specify the wrong one. That is, specify NTSC if your source is actually
PAL, or vice versa. Of course, this assumes your card is able to handle
both signals, and will sync to the actual incoming scanning frequences,
not the official ones for the standard you specify. What happens is that
it looks for the colour information in the wrong format, doesn't find it,
and give you a black-and-white signal instead.

What a pity my VideoSpigot LC is too smart to be fooled by this trick :-}...

I can't remember offhand what VDSetInputColorSpaceMode does, but, yes,
all references to "thing" in the pre-release interfaces are now "component",
so a "VideoDigitizerThing" is now a "VideoDigitizerComponent". Are your
interfaces all up-to-date?
