Tuesday, October 16, 1990 10:00 p.m. Eastern Time
|
|
Topic: Programming Environments
|
|
Forum Leader: Dave Sugar (AFL Dyfet)
|
|
|
|
AFL Dyfet Okay, I guess we are ready to get started...:)...What do you wish
|
|
to know about
|
|
AFL Dyfet Shanoj?
|
|
ShanoJ Anyone here have any Scheduler experience? It's really beginning
|
|
to annoy me.:(
|
|
ShanoJ Well, I need to use the Scheduler for Twilight, and it just
|
|
doesn't seem to
|
|
ShanoJ work for some people... :( I call _SchAddTask, after checking to
|
|
make sure the
|
|
ShanoJ busy flag IS set, and the task never gets called!! :(
|
|
WinkieJim Shano, BTW, Twilite disables my keyboard from working :)
|
|
ShanoJ Well, the next version of Twilight (due out for the Twilight Time
|
|
contest)
|
|
ShanoJ should fix ALL of those problems. Thing is, unless I can figure
|
|
out what's up
|
|
ShanoJ with the Scheduler, it STILL isn't going to be able to save the
|
|
screen on some
|
|
ShanoJ people's GS's.... :(
|
|
Function Does anyone have any source code for cataloging a disk under
|
|
GS/OS?
|
|
A2GS No....but I can get some to you...
|
|
Function That would be great if you could.
|
|
WinkieJim Function, all you have to do is use the GEtDirEntry function to
|
|
get the
|
|
WinkieJim files in any directory
|
|
Function Yeah, I know how and have even done it. I just need to make some
|
|
things work
|
|
WinkieJim where are you having problems?
|
|
Function I need to print all of the info to the screen using the console
|
|
driver. The
|
|
Function console driver is not the problem either.
|
|
Function Whenever I try to print stuff to the screen it comes out as
|
|
control chars
|
|
WinkieJim inverse you mean?
|
|
Function yeah
|
|
WinkieJim Well the filenames and pathnames GS/OS gives, has the high bit
|
|
clear.
|
|
Dave Lyons (Not necessarily! Standard legible characters have their high
|
|
bits clear, but high-ascii is
|
|
Dave Lyons permissible in some file systems, like AppleShare.)
|
|
WinkieJim Ok, well standard ProDOS names then.
|
|
Function I can print the names fine, just not the blocks, filenames and
|
|
mod/creation dat
|
|
WinkieJim you either want to try setting the high bit or set the output
|
|
filter to do it
|
|
WinkieJim for you.
|
|
AFA Gary J You're using GetDirEntry, right Function?
|
|
Function yes
|
|
AFA Gary J Are you converting the mod/creation date, etc. to ASCII
|
|
characters before
|
|
AFA Gary J trying to print them? (Function)
|
|
Function no. I have no idea how
|
|
AFA Gary J That's why they're inverse, etc. then.
|
|
Function I know. I just don't know what to do
|
|
WinkieJim First byte= Seconds
|
|
WinkieJim 2=Minutes
|
|
WinkieJim 3=Hour
|
|
WinkieJim 4=Year
|
|
WinkieJim 5=day
|
|
WinkieJim 6=month
|
|
WinkieJim 7=null
|
|
WinkieJim 8=weekday
|
|
WinkieJim just turn it in the appropriate number or word (month 1= January
|
|
12 Dec...)
|
|
AFA Gary J Most of the dir info stuff comes back as pure hex values. Some
|
|
things like
|
|
AFA Gary J dates/time is in a format like WinkieJim is displaying :)
|
|
AFA Gary J You can use the Integer Math toolset to do the conversion to
|
|
ASCII for you.
|
|
|
|
WinkieJim Ok big question for you all:
|
|
WinkieJim I have a NDA with a menu bar in it's info bar.
|
|
WinkieJim The menus come from resources.
|
|
WinkieJim When I resize the window or move some thing in front of it (not
|
|
when I move it
|
|
WinkieJim around the screen) it will freeze at the DrawMenu call.
|
|
WinkieJim The resource file is available (I know this due to NL 3.0 :)
|
|
WinkieJim (before when the rescource file wasn;'t avail it would crash, but
|
|
now it freezes up)
|
|
WinkieJim I've followed TEch Note #3 to the letter and still can't see where
|
|
it is
|
|
WinkieJim messing up.
|
|
Dave Lyons WJ, how do you know it's available *during* the info bar draw
|
|
call?
|
|
Dave Lyons You *do* have to do the Get/SetCurResourceApp bit in your info bar
|
|
defproc.
|
|
WinkieJim I call SetResourceApp with my user ID in the info bar defProc.
|
|
WinkieJim I also put a break in just before the DrawMenu call and went to NL
|
|
and saw
|
|
WinkieJim the resource file was available.
|
|
Dave Lyons Oh, okay. How 'bout the port? Did you do a SetPort to anything?
|
|
I believe DrawMenu/etc will
|
|
Dave Lyons toast if the current port is invalid.
|
|
WinkieJim And as I said, it will work if I don't cover the menu bar with
|
|
something else
|
|
WinkieJim or resize the window
|
|
WinkieJim Wouldn't a call to set the window's port in a info draw cause
|
|
problems?
|
|
WinkieJim (i.e. doesn't the window manager call StartInfoDraw and doesn't
|
|
that set the
|
|
WinkieJim current port corectly?
|
|
Dave Lyons (Good point...I think you're right)
|
|
WinkieJim (TechNote #3 doesn't do any port setting)
|
|
AFA JoeyS (technotes can't set ports)
|
|
WinkieJim Ha Ha Joey :)
|
|
Dave Lyons Still, check in Nifty List right before it fries & see what the
|
|
port is set to (it's probably the
|
|
Dave Lyons window manager's port, which should be okay).
|
|
WinkieJim :) Tech nbote #3 states: Do not switch to the windows port for
|
|
drawing :)
|
|
WinkieJim The things that gets me is that it doesn't freze if I just move
|
|
the window a
|
|
WinkieJim little around the screen.
|
|
Dave Lyons WJ, if you just move the window around it's just copying the
|
|
picture of your window, not calling
|
|
Dave Lyons your info bar defproc or content defproc to draw anything.
|
|
WinkieJim But will if I resize the window or move it so the info bar is
|
|
obscured by
|
|
WinkieJim something.
|
|
WinkieJim that' pretty much what I assumed, but it still leaves with me
|
|
wondering, why?
|
|
WinkieJim :/
|
|
WinkieJim I don't suppose adding menu items to the bar after creating it
|
|
would cause
|
|
WinkieJim problems?
|
|
Matt DTS (To the bar, yes. To menus in the bar, no. :)
|
|
WinkieJim nope the menu titles remain the same...I just add menu items to
|
|
the end of two
|
|
Dave Lyons Does your menu pull down okay?
|
|
WinkieJim of the menus and call calc menu size right after.
|
|
WinkieJim It pulls down, selects and works perfectly otherwise.
|
|
Dave Lyons And the newly-added items are in there, right?
|
|
WinkieJim Yup. (originaly off the menu area until I figured out to call
|
|
CalcMenuSize, but
|
|
WinkieJim they are there and work perfectly.)
|
|
Dave Lyons I dunno...send me the object & I'll see what I can do.
|
|
WinkieJim Thanks, dave. I'll get it out asap. dang thing is driveing me
|
|
batty and is
|
|
WinkieJim preventing me from going to beta test stage.
|
|
AFA Gary J Programming environments tonight...uh.. let's see. Anyone here
|
|
using the
|
|
AFA Gary J MAX/Edit editor?
|
|
AFA Gary J I actually like the Orca editor well enough, but I need the
|
|
ability to edit
|
|
AFA Gary J more than one file at a time (and it would also be nice to be
|
|
able to edit
|
|
AFA Gary J files > 64K). Would MAX/Edit be overkill for such miniscule
|
|
wants?
|
|
Matt DTS I have a problem with MAX/Edit (and it's ancestor, the SDE editor)
|
|
in that...
|
|
Matt DTS ...it uses new user IDs for each file it edits and does NOT
|
|
dispose of them when you quit the editor.
|
|
Matt DTS This is how it does the "You can switch from Merlin to APW with
|
|
your files intact" bit. The memory is
|
|
Matt DTS not purgeable, either.
|
|
AFA Gary J Hmmm. That's not good.
|
|
Matt DTS If keeping files in memory is really that important to you, this
|
|
is the way to do it, but I'd rather
|
|
Matt DTS use the memory in my current application and do a bit of disk
|
|
access when I reenter the editor instead
|
|
Matt DTS of having to explictly unload files I'm editing before quitting to
|
|
free their memory.
|
|
Matt DTS GA.
|
|
AFA Gary J I'm not really concerned about the source staying in memory. I
|
|
just want to
|
|
AFA Gary J switch between multiple files while editing. <done>
|
|
AFL Dyfet Okay, who wishes to inject a new question at this point??
|
|
ShanoJ APW 2.0? ZapLink?
|
|
AFL Dyfet Go ahead Jonah...
|
|
ShanoJ Welp, does anyone know how APW 2.0 is coming along, and whether
|
|
there are plans
|
|
ShanoJ to add the ability to set the OMF bits with ZapLink?
|
|
AFA Gary J That would be a nice addition, Jonah.
|
|
ShanoJ Hell, that would be a NECESSARY addition. With all of the 3200
|
|
color stuff I
|
|
ShanoJ do, ZapLink is basically useless to me without it. :(
|
|
AFA Gary J Must be bank aligned, etc., eh?
|
|
DVS Softwr Would my OMF program in the libraries do the trick?
|
|
ShanoJ Actually, it's the nospecial bit that's important. I need to get a
|
|
lot of $01
|
|
ShanoJ space, and I can't have my program loaded there... :(
|
|
AFA Gary J Your OMF program sets the KIND field, correct?
|
|
DVS Softwr what does he need?
|
|
ShanoJ Dunno, DVS, what does your program do (I haven't seen it, sorry...
|
|
:)
|
|
AFA Gary J That would work for you then, Jonah. That's in the KIND field.
|
|
AFA Gary J Jonah, do you really have trouble with your program trying to
|
|
grab $01 if you
|
|
AFA Gary J don't set the KIND field to not load in $01?
|
|
ShanoJ Well, I do SOMETIMES. It shouldn't be a problem much, because it
|
|
tries to grab
|
|
ShanoJ $012000, which should be pretty much reserved for QDII Shadowing,
|
|
but I thought
|
|
ShanoJ I should be safe and make sure that it can't be loaded there....
|
|
AFA Gary J Is your program an EXE file or a S16 file (when you're developing
|
|
it)?
|
|
ShanoJ S16. Has to be, or else APW uses that memory and I'm screwed. :(
|
|
AFA Gary J Yes.
|
|
AFA Gary J I was just wondering. I have some programs that use $012000, and
|
|
as long as
|
|
AFA Gary J they're S16 files, I don't have trouble with them trying to
|
|
reside in $01. But
|
|
AFA Gary J the main segment is rather large. That probably makes a
|
|
difference.
|
|
ShanoJ Matt, Dave, what's the official position on that? If you HAVE to
|
|
use the
|
|
ShanoJ $012000 space, should you set the nospecial bit in the KIND field,
|
|
or is that
|
|
ShanoJ only extra work?
|
|
WinkieJim If you don't set it does it usaly load there?
|
|
AFA Gary J I would tend to want to do it before releasing the program upon
|
|
the world, just
|
|
AFA Gary J to be safe.
|
|
WinkieJim gary...that's what I was just thinking of :)
|
|
Matt DTS If you "have" to use any specific address, you have to be prepared
|
|
that you can't get it.
|
|
Matt DTS Just because you didn't load there doesn't mean that some DA or
|
|
INIT didn't. You can try for it
|
|
Matt DTS but you have to handle it gracefully if you can't get it.
|
|
AFA Gary J What, Matt?? No SysFailMgr call? :)
|
|
WinkieJim I usually just crash into the monitor...no system errs for me :)
|
|
Dave Lyons I believe when GQUIT loads applications it asks the loader *not*
|
|
to use special memory--and then if
|
|
Dave Lyons that fails it trying loading again, with no restrictions.
|
|
ShanoJ Ya, but the $012000 space should be fairly safe, as if a DA or INIT
|
|
was loaded
|
|
ShanoJ there, P8 is screwed, too...
|
|
Matt DTS Maybe no one's tried to launch P8 on that system in a while. Be
|
|
prepared for when you can't get it.
|
|
Dave Lyons Properly-loaded DAs don't have code in special memory--but they
|
|
might allocate non-special memory,
|
|
Dave Lyons so grab $012000 before you call DeskStartUp.
|
|
ShanoJ Heh, I actually AM prepared, Matt! For once in my life I checked
|
|
for a valid
|
|
ShanoJ handle. See, I'm learning. Slowly but surely... :)
|
|
AFA Gary J I have a CDA that does NOTHING but grab $012000, just so I can
|
|
test my
|
|
AFA Gary J software :)
|
|
AFA Gary J (It's also fun to see how other software products handle the
|
|
situation too :)
|
|
|
|
ShanoJ Anyone have any thoughts on how to display 3200 color pictures
|
|
from an NDA?
|
|
ShanoJ I need to shut down all of the interrupt sources, but that's a
|
|
no-no when the
|
|
ShanoJ main program isn't the one doing it.... :(
|
|
Matt DTS Jonah: There are some tasks desk accessories should just leave
|
|
alone.
|
|
|
|
ShanoJ Does Prizm work well/reliably for anyone here?
|
|
AFL Dyfet (I don't use Prizm myself..prefer the shell)
|
|
AFA Gary J (same here)
|
|
ShanoJ Ya, me too. That's why. :(
|
|
AFL Scott Prizm is very unreliable, IMHO. I have it crash or trash the
|
|
target volume
|
|
AFL Scott regularly.
|
|
AFL Dyfet I never found problems with Prizm simply because I never really
|
|
used it :)
|
|
AFA Gary J (trash the target volume? ugh. That's serious)
|
|
AFL Dyfet I had to re-construct my hd recently, Scott...What a pain :(...
|
|
AFL Scott (that's why I don't use it! :))
|
|
ShanoJ Ya, I had it erase source files, refuse to compile stuff, etc,
|
|
etc, etc.
|
|
ShanoJ Too bad, too, it COULD be really nice. :(
|
|
|
|
Nuzz is it too late for a question?
|
|
AFL Dyfet No Nuzz...ga...
|
|
Nuzz I'd like to know how GSOS formats the Text in the ClipBoard
|
|
window
|
|
Dave Lyons Well, GS/OS doesn't have anything to do with the clipboard.
|
|
Dave Lyons Are you asking about the Finder's "Show Clipboard" window?
|
|
Nuzz Yes, finder, sorry
|
|
Dave Lyons I believe it just calls LETextBox2 with all the text, and with a
|
|
rectangle the width of
|
|
Dave Lyons the Clipboard window. LETextBox2 is doing the word wrapping.
|
|
Nuzz is Scrap type 64 a line edit scrap?
|
|
Dave Lyons Scrap type $0064 is Text Edit style information--goes along with a
|
|
Text scrap.
|
|
Nuzz If there is style info, does the finder use this when showing
|
|
clipboard?
|
|
Dave Lyons Nope, the Finder only uses the Text and Picture scraps ($0000 and
|
|
$0001).
|
|
Nuzz Dave, just so I have it straight, you're saying that Finder will
|
|
word wrap to
|
|
Nuzz the size of the window (Horz), irregeardless of how the text was
|
|
"cut"
|
|
Nuzz <bad spelling>
|
|
Dave Lyons Yes, I think that's what it does. Carriage returns still force
|
|
new lines, but so does wrapping.
|
|
Nuzz Hmm, I've cut some TextEdit stuff and the finder seems to respect
|
|
the original
|
|
Nuzz word wrap.
|
|
Nuzz <without a CR>
|
|
WinkieJim it might just be luck...
|
|
WinkieJim (i.e. both windows the same width)
|
|
Nuzz Nope, the TE lines are much narrower than the Clip window
|
|
Dave Lyons Are there any carriage returns in the text you cut?
|
|
Nuzz Not on all lines
|
|
Nuzz I looked at the lines in question and there are no CR's at the
|
|
wrap point
|
|
Nuzz yet the clip window is just as the TE
|
|
Dave Lyons Looked at the text in Text Edit, or the $0000 Scrap on the
|
|
clipboard?
|
|
Nuzz The $0 Scrap type
|
|
Nuzz I looked at it with NL
|
|
Dave Lyons That's strange. I'm sure it's not using the $64 scrap...the
|
|
Finder doesn't even start up TE.
|
|
Nuzz I am trying to duplicate this.
|
|
Nuzz Right now, MY Clipview window only wraps at CR's. Cuts off words
|
|
that are wider
|
|
Nuzz than the window
|
|
Dave Lyons I just tried it (Copy from a Text Edit control) and it shows up
|
|
with no wrapping in the Finder.
|
|
Dave Lyons (Oops, I take back the part about the Finder using the *current*
|
|
width of the Clipboard window--
|
|
Dave Lyons it seems to have a hard-coded width.)
|
|
Nuzz I'll try it again, and get back to you on it Dave. Thanks for the
|
|
help
|
|
|
|
WinkieJim SPeaking of LETExtBox...anyone know how to find out how high in
|
|
pixels the text
|
|
WinkieJim in a LETextBox2 is?
|
|
Dave Lyons WJ, I don't know of a way (that would be too easy).
|
|
WinkieJim :/
|
|
Dave Lyons If you have a *lot* of text, I don't recommend using LETextBox/2
|
|
anyway--they aren't very fast.
|
|
WinkieJim I hate to have to have a super long vertical data area with only
|
|
2 lines of
|
|
WinkieJim text :)
|
|
Dave Lyons You don't *have* to, WJ...look at the Macintosh Finder's
|
|
solution--the scroll bars are never active!
|
|
Dave Lyons (Good solution, eh?)
|
|
WinkieJim I know I don't have to and don't want to, but if I can't find the
|
|
length of
|
|
WinkieJim a LETextBox2..I have no choice
|
|
WinkieJim because the information displayed can be almost anylength (well up
|
|
to $FFFF)
|
|
WinkieJim and with word wrapping it could end up anywhere in hight.
|
|
Dave Lyons I don't think the height can exceed $3fff, or QD would crash.
|
|
WinkieJim ($FFFF in size of the text data)
|
|
Dave Lyons (By the way, don't call LETextBox with length=0. It'll toast on
|
|
you.)
|
|
WinkieJim I'll put a check in for that one...
|
|
|
