Tutorials on using Arrays in REV

[Thomas McGrath III]

Where is the best place to find tutorials on using arrays in RR?

I tried using XML in my project and have not been able to smoothly use  
it for what i want so I am thinking that arrays would be better.


Thanks Tom McG

Re: Should I have to check compiled programmes?

In my opinion, you should definitely expect to check standalone apps 
thoroughly. There are a number of things that can cause differences 
between IDE and standalones, plus making sure you have the correct 
standalone settings and inclusions. Beyond that, it's important to 
test installers, test your software on another computer, and so 
on--there are a lot of potential gotchas and the final round of 
testing helps to minimize them.

Since he never really opens the stack per se, but loads it into memory 
with "start using", does he have to use the "close" command or should he 
use "stop using"?

Re: RevZip

[-= JB =-]

Both you and Len said to use RevZipOpenArchive.
That is what I used and the docs say to check the
result for any errors.  I did and the result said it is
not a Zip Archive.

After reading all the replies and have decided not
to bother using RevZip.

Yes, see this bug 

It happens if you add or remove files from a zip that was not
originally created in Revolution.


 Also I don't see any command to open a file that is not a
 zip archive and compress it unless I already have a zip
 archive open.


You need to specify a file name, open that file as a zip archive ready
for updating, add new files to it, then close the zip file. Check the
docs for the following commands:
revZipOpenArchive
revZipAddItemWithFile
revZipCloseArchive


 Is RevZip used only for some special RevZip files or is
 it for any Zip Archive?


In theory, it works for any zip file, but at the moment, you can only
edit zip files created in Rev. Unfortunately, this makes the zip
library almost useless, since the only way to test whether a zip file
will work is to risk corrupting it permanently and losing any data in
it.

unhappy barber's pole

[Colin Holgate]

Ok, I bet this will be one of the most subtle bugs ever to be reported!:

The Image Library has a number of animated barber's pole. The last  
one, ID 210067, has its 3rd and 4th images reversed. That is, the  
frame that should be number 3 is showing the image from frame 4, and  
vice versa.

CGI's on a linux server

[Michael Doub]

I have been able to install the current engine on my ISP's linux server in
cgi-bin and am able to run the simple hello world script.  I am now trying

I have given up on using Rev zip feature and use shell for Mac and

Here is a small snippet I last used in on of my apps.  If anything is

Hi Colin,

Good to hear from you again, and very good to see you in this forum.

Yes.  Some of these are "normal oddities", an excellent phrase!

I think you are in a valuable (to Rev) moment, and I urge you to give us the 
benefit of it.  Two things can happen when someone - especially someone 
experienced - encounters Revolution.  They run across a whole bunch of strange 
behaviours, throw up their hands in exasperation, and walk away.  Or they run 
across these strange behaviours, find their way around them, and find ther way 
past them to the productivity that they can nonetheless achieve; and quickly 
cease to see the quirks.  That's better, but unfortunately it means that the 
chances of the quirks being resolved are not increased.  I hope you'll do the 
second, but before you acquire the blindness that the rest of us now enjoy, I 
hope you'll make good use of your password to report all the oddities you see.


When I first started working with Metacard and shortly thereafter Revolution, 
I generated a slew of reports just as you are doing now.  (Unfortunately at 
that time neither the Metacard nor the Revolution teams, in different ways, 
were very responsive.  It was quite a long struggle from their friends/clients 
to persuade them that an open bug database would be a good thing.  I'm 
delighted to say that RunRev is now very different in its attitude, and 
genuinely listens to its users, and is far more dedicated to balancing 
development of new features with improvement and fixing of the existing 
product; and also substantially better equipped to do so.)  But now of course, 
I no longer notice most of these issues, until I witness a new colleague 
attempting to use the product - at which point I often find myself blushing, 
sputtering, and waving my hands.  After a few months, I think we unconsciously 
swerve past the open manholes etc, without even seeing them - as a result they 
are never reported, and have no chance of being fixed.


So please make good use of your password when it finally arrives!  I think 
Revolution is the true and a worthy descendant of HyperCard*, and I hope 
you'll find it so.  There's much here to appreciate, including many thoughtful 
and excellent extensions to the language and architecture.  But Revolution 
also partly pays the price for spanning several platforms; and also its 
history, which I won't bore with you now, means that the IDE has developed 
separately from the engine.  Stick with it, it's worth it - but please do 
report the things that strike you as odd - you'll mostly be right!


- Ben

Re: How to set a field to Caps or TitleCaps

[Mark Schonewille]

Hi Hugh,

That should be something like this

on keyDown theKey
  put toUpper(theKey) after me
end keyDown

for all caps and...

on keyDown theKey
  if me is empty or char (word 2 of the selectedChunk) of me is space  
then

put toUpper after me
  else pass keyDown
end keyDown

to have the first char of each word in upper case. You'll have to add  
a few lines to handle exceptions, such as backspace, punctuation etc.  
You want to use matchtext with regex to check for punctuation.


Or do you mean that you really want titles to be in all caps? Perhaps  
that could be something like


constant dot = "."
on returnInField
  if not (the last line of me contains dot) then
put toUpper(the last line of me) into the last line of me
  end if
end returnInField

Obivously, there might be problems with this. If it doesn't work for  
you, you might want to be more specific about when this should happen.


Best regards,

Mark Schonewille

Don't pass the message. You can't replace the keystroke that is passed 
to the engine, but you can put a different keystroke directly into the 
field instead. Change the handler to:


on keydown tk
 put toUpper(tk) into the selection
end keydown

Make sure you place this handler only into the field it controls, or 
else check to be sure the target is a field you want to work with. 
Otherwise all typing in the card or stack will be blocked.

Re: question regarding print out of objects listing from the application browser

[Joe Lewis Wilkins]

Would this need to be cross platform, or would a Mac solution be  
acceptable?


Regardless, I think I would lay everything out using Rev stacks, take  
screen shots of the finished stacks/cards/etc., and assemble one or  
more PDFs of the results. On either platform, this could be done by  
creating the layouts of the screen shots, along with any descriptions  
you need/want using MacDraft or PCDraft. Very easily done. I do it all  
the time on Macs. You can create multi-page PDFs of various page sizes.


I hope I've understood what you're attempting to do.

Joe Wilkins

Apologies in advance if this information is something easy to find in
the on line help or list archives, but here goes anyway.  I think it
relates somewhat to the discussion recently about distributed  
development,

keeping things in text files, etc.


Context:

As part of the set of technical design documents for a software  
project,

I am thinking of creating a prototype in REV.  This would then be an
easy way to 'catalogue' the entire set of objects in the application.

In other words, the REV stack would be a spec for developers with each
button, each field, each label, each menu choice organized visually,  
in a
semi- working prototype they could actually run, as well as,  
providing the

"application browser" tool to see a hierarchical view of, and navigate
amongst objects.  It would even be possible to list comments for each
object using the associated script.  Various methods or functions and
handlers could also be stubbed out or written in psuedo-code, either  
at

the object level or in the stack or card scripts.

Prototyping seems like a nice way to create a technical design spec.

Problem:

To read this "spec", you need REV.  (hey, buy it, right!?  or download
free trial).  What about the audience of non technical users or  
business

stake holders - what if they want to see a PDF or something?

Solution:

Unknown?  Is there an easy way to print out or save in text form the
same info being displayed in the application browser, and/or various
object scripts?

I can think of a 'hard way', hopefully someone will have a tool to
suggest for an easy way?

Re: Error -43 starting recording

[Peter T. Evensen]

Hi, Eric,

That doesn't really help.   I'm still getting the error.  The second 
link only apply to streaming Real Audio media.  I don't understand "File 
not found" (if that indeed is what error -43 means with record sound 
file) means in this context.  It's supposed to be creating the file.


Anyone ever see this?

I am on Windows XP, running Rev 2.8.1

I had this working a while ago.  Now when I come back to the project, 
it isn't working.

question regarding print out of objects listing from the application browser

[Sadhunathan Nadesan]

Apologies in advance if this information is something easy to find in
the on line help or list archives, but here goes anyway.  I think it
relates somewhat to the discussion recently about distributed development,
keeping things in text files, etc.


Context:

As part of the set of technical design documents for a software project,
I am thinking of creating a prototype in REV.  This would then be an
easy way to 'catalogue' the entire set of objects in the application.

In other words, the REV stack would be a spec for developers with each
button, each field, each label, each menu choice organized visually, in a
semi- working prototype they could actually run, as well as, providing the
"application browser" tool to see a hierarchical view of, and navigate
amongst objects.  It would even be possible to list comments for each
object using the associated script.  Various methods or functions and
handlers could also be stubbed out or written in psuedo-code, either at
the object level or in the stack or card scripts.

Prototyping seems like a nice way to create a technical design spec.

Problem:

To read this "spec", you need REV.  (hey, buy it, right!?  or download
free trial).  What about the audience of non technical users or business
stake holders - what if they want to see a PDF or something?

Solution:

Unknown?  Is there an easy way to print out or save in text form the
same info being displayed in the application browser, and/or various
object scripts?

I can think of a 'hard way', hopefully someone will have a tool to
suggest for an easy way?

Re: Fixed Width Fonts #2

I'm not sure why it showed up two months later, either.  I think we

Scott,

Thanks for your help.  Curious thing, though.  I created a script  
( below) which works fine when I run it line by line in the  
debugger, and _sometimes_ when I run it from a button, and then the  
next time(s), from the same button, it just chugs along and and  
returns nothing.  Any ideas?


on mouseUp
   global gFixedWidthFonts

   put empty into field "fixedWidth" of cd 1 of stack "FixedWidth"
   put "i" into field "skinnyLetter" of cd 1 of stack  
"FixedWidth"

   put "w" into field "fatLetter" of cd 1 stack "FixedWidth"

   put the fontnames into vAvailableFonts
   sort lines of vAvailableFonts

   repeat with x = 1 to the number of lines of  
vAvailableFonts   set the textfont of field "skinnyLetter"  
to line x of vAvailableFonts
   set the textfont of field "fatLetter" to line x of  
vAvailableFonts


   wait .05 seconds -- needs time to evaluate, maybe? dunno
   put the formattedwidth of fld "skinnyLetter" into vSkinny
   put the formattedwidth of fld "fatLetter" into vFat

   if  vSkinny = vFat then
   put line x of vAvailableFonts &return after field  
"FixedWidth" of cd 1 of stack "FixedWidth"

   end if

   end repeat

  put field "FixedWidth" into gFixedWidthFonts

Re: while I await my password...

[J. Landman Gay]

Colin Holgate wrote:
While I wait for my bug reporting password (are those created 
manually?),


I'm not sure if they are manual or not, but you should have received it 
by now. Could the reply have gone into your spam box? You might try 
logging in anyway just to see if it is registered yet.


I'll list some of the things that seem odd to me, to give 
you a sense of what I mean, and for you to say if it's normal oddities:


Place some little arrows, and resize them (you probably don't have a 
good reason to do that, but do it anyway). As you resize them they will 
change between arrows, a horizontal scroller, and a vertical scroller, 
depending on the width and height you make it. For example, something 
roughly square will be the arrows, something a bit narrower will be a 
vertical scroller. The inspector continues to report that it's little 
arrows, unless you deselect and reselect them, then it changes to the 
type it looks like. The final application shows the type it ended up 
like on Mac, but shows resized little arrows on Windows.


Right, all normal, except for maybe the last part. In reality there is 
only one "scrollbar" type of object. The way it looks depends, as you 
noticed, on the dimensions. The engine will automatically resize the 
arrows if the rectangle is small enough; otherwise it draws a regular 
scrollbar. The orientation of the scrollbar depends on the ratio between 
the height and width.


Rev attempts to make the distinction for you by putting different types 
of scrollbar settings into the tool palette, which makes it look like 
they are different, but they aren't. Rev does the same thing with 
buttons; there is only one button type, and the appearance and behavior 
depend on the button's style propery. The tool palette makes it look 
like there are different types of buttons, and the inspector reinforces 
this by removing certain settings depending on which button it is 
displaying.


The inspector is apparently not updating its pane info when you resize 
the scrollbar. This may be considered a bug, I suppose.




If you make a scroller by starting with little arrows and glitching it 
as above to become a scroller, or if you intentionally select it to be a 
scroller in the inspector, the final scroller does not scale correctly 
when you drag the thumb. If the mouse is over the thumb at the top of 
the channel, by the time you've dragged to the bottom of the channel the 
thumb is nowhere near the mouse position.


With little arrows (just drag them out to make them, and don't mess with 
the size), the bottom arrow is deemed to be under the mouse right up to 
over half way up the upper arrow. The upper arrow is only active in the 
top half of the arrow.


Bug.



Drag out a QuickTime object and connect it to a movie. Resize the 
object, do a save of the stack, close it, and open it again. The object 
is also back at the natural size of the QuickTime movie, and not at the 
size you made it.


Normal behavior, and works the same in image objects too. Images and 
players will resize to fit their media at the next redraw of the card 
(you will see the behavior you describe if you just go to another card 
and back, too.) To prevent this, set the lockloc of the image or player 
to true. That will disable the auto-resize feature. Auto-resize is handy 
if you want to use only one object to display different files at 
different times, but if you are only showing one file permanently, 
locking is the answer.




Default buttons don't behave like OS X default buttons. They constantly 
pulse. What is supposed to happen is that when you click on them they 
stop pulsing in the brighter state, and if you roll off them they become 
empty, like a non-default button. In  Rev they just continue to pulse.


Probably a bug. The default button style on OS X was a problem for a 
while and used considerable CPU cycles. That was fixed, but it sounds 
like newer OS behavior hasn't been implemented. Didn't they always pulse 
in older implementations of OS X?

Re: Should I have to check compiled programmes?

[Len Morgan]

Is it possible that the button that causes the problem is the last one 
(or first one - i.e., a boundary condition)?  If so, try adding a 
"dummy" number to the end or beginning of the list and see what happens.


len morgan


It's nothing clever - just an mouseUp
with generic code which is used by
a number of other buttons - which all
work. Just a matter of checking if the
label "12" is in a list "10,11,12" and
acting accordingly. It was in the list
and the other numbers were found.

As I said, it ran OK in the IDE so it's
something that happens during
compiling.

Re: RevZip

I think you are looking for the revOpenArchive (or something close to 
that).  Once you open it, you have to use the Rev commands to get a list 
of the contents and then loop your way through it to get the individual 
files.

It was certainly plenty fast enough, especially when you think that a 
Macintosh Plus was 8 MHz, and it ran HyperCard ok. Having a machine 
that is 300 times faster, not counting the number of bits and caching 
improvements, should yield something that works!

Re: Should I have to check compiled programmes?

[Thomas McGrath III]

Ross,

I responded to this in the RR Forums this morning. I think you have  
something going on in the code or environment related issues. The  
compiler has been running smooth for a while now and I don't think  
your problem lies there.


You may want to check the obvious causes:
Library not installed/included
SubStack not check for inclusion
Pathname changed (Static versus Dynamic)
If then (if the environment is "Development" then...)
Also, Since you are working with numbers as labels I would look into  
the naming (not label) of these buttons. I would check if you are  
using a naming scheme that could be causing your problem.


Since your code is top secret maybe you can share what types of things  
you are doing behind the scenes with the code i.e. Loading a picture,  
URL, accessing an external data file, mySQL etc.

Welcome to this list.
Your first send did show up here.
But it's difficult to reply:
Is it an affirmation or a question?
As for me, if standalones may have problems (due to some missing  
inclusions or, of course, my code :-), I did not encounter the issue  
you report.

Re: Arrays and Recursion: Scrabble with Revolution

[Mark Schonewille]

Hi John,

Probably, you are using a slightly older version of Revolution. A nice  
addition to the Scrabble stack would have been a version check to see  
if private handlers are supported. You did the right thing, changing  
the private handlers into "public" (or should I say generic?) ones.


Best regards,

Mark Schonewille

Just be aware that since you are modifying the file on disk anyone can  
open your database file while it is open in your application or make a  
copy of it while it is open in your application and then open it  
whenever they would like (at least with SQLite).

Re: Loading random files

[Mark Smith]

Alan, if you have a list of files, words or anything else, for that  
matter, called 'tList"


put any line of tList into tFile

will choose a line at random.

However, bear in mind that the choices are not guaranteed to be ones  
not already made, so you may want to do something like this:


put random(the number of lines in tList) into tLine
put line tLine of tList into tFile

delete line tLine of tList -- make sure it doesn't get chosen again

Best,

Mark

Opps!

Just realized that the IP Addresses are wrong in the example, in the 
real app it's ok. I forgot that my router munges the the LAN IP 
Addresses, so where I've put 192.168.1.101, read 192.168.1.87 and 
where 192.168.1.102 read 192.168.1.105.


Another question is:

Why do I get a read error and not a write error:

socketError: 192.168.1.87:6000|looktowindward Error 54 reading socket

I'm not reading on the Client, I'm trying to try data.

You don't get a read error. You get a socket error (-- Connection reset 
by peer. This occurs when an established connection is shut down for 
some reason by the remote computer.) which the error string misleadingly 
indicates was a read error. This probably comes from your system (which 
OS etc. are you using ?), and is merely passed along by Rev.


It probably does happen when you try to write to the socket after it has 
been closed.


I'd recommend adding a 'socketClosed' handler and see if that helps ...



Questions:

Why do I sometimes not get a socketError or a socketTimeout ?

Why does it sometimes repeat (as it should) for a few times and then 
stop?


Don't know :-(  but try adding the socketClosed handler and see if that 
helps. I have also asked some questions / made some suggestions below.

If it doesn't, resend this log

Here is the code:

The mouseUp handler are in the main stack of the app and the


The following is including in the App using the "start using" command:


--  StartServer

function StartServer theServerPortNumber,theClientAllowList

  get DebugLogString("StartServer - Accept:" && theServerPortNumber)

  put theClientAllowList into sgServerClientAllowList
  accept connections on theServerPortNumber with message 
"ServerContactedByClient"


  return empty
end StartServer


--  ServerContactedByClient

on ServerContactedByClient theIPAddress
  local myClientIPAddress
  local myResult

  put the result into myResult


what do you expect 'the result' to contain at this point ?
  get DebugLogString("ServerContactedByClient:" && theIPAddress && 
myResult)


  if myResult <> empty then
breakpoint
exit ServerContactedByClient
  end if

  set the itemDelimiter to ":"
  put item 1 of theIPAddress into myClientIPAddress

  if myClientIPAddress is not among the lines of 
sgServerClientAllowList then
get DebugLogString("ServerContactedByClient, Bad Client:" && 
theIPAddress)

close socket theIPAddress
I'd recommend a 'exit ServerContactedByClient" at this point - otherwise 
you are about to read from a socket you just closed.

  end if

  read from socket theIPAddress for kPacketCountSize chars with 
message "ServerReceivedPacketSize"


end ServerContactedByClient



--  ServerReceivedPacketSize

on ServerReceivedPacketSize theIPAddress,thePacketSize
  local myResult
  local myPacketData
  local myPacketID
  local myPacketCommand
  local myConnectionID

  put the result into myResult


again, what do you expect in 'the result' here ?
  get DebugLogString("ServerReceivedPacketSize:" && theIPAddress && 
thePacketSize && myResult)


  if myResult <> empty then
get DebugLogString("ServerReceivedPacketSize, Error:" && myResult)
breakpoint
  end if

  read from socket theIPAddress for thePacketSize chars
  put the result into myResult
  put it into myPacketData

Note this is a blocking read. That will normally work OK (since the 
client sends the packet size followed by the data), but it is not 
robust. If the client was forced to split the data into different 
packets (e.g. if the data was relatively large), and the subsequent 
packet was lost in the network (i.e needed to be NAK'ed and then 
retransmitted), then this could cause your handler to block for an 
arbitrarily long period - up to the timeout interval.


It's up to you, but I would NEVER do a blocking read - I'd simply do

  read from socket theIPAddress for thePacketSize chars with message 
"ServerReceivedPacketData"


and put most of the following code into that new handler (finishing, of 
course with another "read from ... ServerReceivedPacketSize")
  get DebugLogString("ServerReceivedPacketSize, Packet Data:" && 
myPacketData && myResult)


  if myResult <> empty then
get DebugLogString("ServerReceivedPacketSize, Error:" && myResult)
breakpoint
  end if

end ServerReceivedPacketSize

Re: UI performance and large data set in Table Object

[bjdevlin]

To be frank, Rev's native table object leaves an awful lot to be desired. 
Quite a few people on this list ended up writing their own table object
instead.  I wrote one with resizable columns and column-click sorting that
was based on a normal scrolling field.  It was lightening fast with
thousands of rows.  

Chipp has made his table control publicly available:
http://www.altuit.com/webs/altuit2/RunRevArchived/Archives.htm and look for
'altFldHeader Control'.  It may well turn out that this serves your needs
better than Rev's table object.

Re: Make a cheap web server with simple no-CGI read write on port 80

[delorme]

Hope it is more readable
___

Hi from France!

The idea of this cheap html server came from "chat server" demo stack.
I tried, it works quite fine.
Next is a sum-up:

On Openstack
.  accept connections on port 80 with message GotAConnection

on GotAConnection aSocket
.  read from socket aSocket for 1 line
.  analyze received line (GET or POST)
.  read from socket aSocket with message GotNextLines

on GotNextLines aSocket , ReceivedLines
.  Analyze ReceivedLines
.  Do any processing you want with the user request
.  Make TheHtmlAnswer from pre-made file + replaced text (wanted GET file ou
POST answer)
.  write TheHtmlAnswer to socket 

Any distant web browser then gets the requested .html files (as forms with
submit buttons), or POST anwsers after button clicks (submits) in previous
sent forms.

Is'nt life easy?
The only limit is that only html text is replied (no image) because no
Apache server is used.
Also have to record socket connections context in a gSocketConnectionsTable
because many connections are available (which .htm file must be sent back
when GotNextLines?).
Thank you for your feedback and own return on experience about making a web
server from Revolution.

cannot use that in any calls to revdb. I have to save to a variable  
which exposes my password to anyone with a bit of expertise.


If the ask password command was implemented as a function, I could use  
it in revdatabaseconnect() as one of the arguements. Since the MySQL

RevZip

[-= JB =-]

I was just playing around with the RevZip command and
when I try to open a Zip file the result says it is not a zip
file.  If I check the file info it says it is a zip file.

Also I don't see any command to open a file that is not a
zip archive and compress it unless I already have a zip
archive open.

Is RevZip used only for some special RevZip files or is
it for any Zip Archive?
