RE: Protecting your Rev apps - freeware options

[MisterX]

Just a couple notes on my experience.
- Freeware is not rewarded usually.
- Shareware neither
- blocking features = more problems in maintenance
- a demo, light and pro version seems better for all purposes (or budgets)

If you want protection for your efforts, leave the demo downloads and wait
for a pro version purchase request. By far the best examples among many
disable save and print (output) features. They dont block the user from
seeing or using the software and if they really need to save they simply
pay.

But anti piracy features are ALL futile. There isn't one I haven't seen
busted whether hardcoded or based on a physical (CD or dongle) protection or
a serial number. Look at DVD regions and protections - millions wasted in
research for nothing except less sales, disapointed customers who can't play
their dvds, incompatible (obsolete) dvd players, and so on...

I tried the freeware path. Then the shareware path. Im still trying to get a
second paypal donations after months of releases, improvements of many
freewares and sharewares.

The economics of it is sad. In the end, the freeware or shareware author
gets discouraged, changes market or builds limited demos and builds less
free features so the yellow leeches end up loosing anyway! In the end the
leech pays more in effort and time than they would have if they had donated
even just a simple burger menu for the author which would have kept the free
flow of free software - usually better featured than most commercial
softwares!

As many other freeware authors, they give ya instant free software, free
updates, free support, quick feedback and fixes where as commercial products
demand support fees or paying upgrades. Which is more expensive? Plus if you
need a feature, just asking or supporting the user gets you that feature
quite fast - compare THAT to commercial software anytime!

Personally, im quite impressed with how Flstudio.com did it. FruityLoops is
a music hypercard (forget midi software for RunRev!) built over Delphi (PC
only) for music production (GarageBand is just a lame lame music box
compared. They have a free fully working demo (no save) on Tucows. Once you
buy it, all updates are free! You can purchase new plug-ins when they are
released and add them to the whole (eg VSTs or DX effects or synthesizers).
The best of it all is that all updates are also free! They have 3 forums for
chat, files and tech. They are truely formidable and selling extremely well!
Their company started also like RunRev! The music business in this case is
quite like RunRev... 

Last but not least, sponsoring freeware authors also increases greatly their
motivations to make more and better software than what's available.
Remember, the best things in life are free. Your donation is just an
opportunity cost between money your would just waste any day on a wimsy
gadget and better software you could use to improve your computer toolset
the rest of your life and literally for free!

Currently Im going to stop doing freeware and work on better paying
solutions. I will bring out less nitrous plugs in (except in my tool chest
where they currently sprouting like mushrooms!) Maybe later there will be
more utilities seeking users wanting to help out but right now, the best
solution seems to create real executables that you can dump on tucows, and
the larger public.

Imagine I have a lego box. If you contribute to it, you can play with it. It
costs you a few lego pieces only. Then instead of playing with your punny
300 pieces you can play with everyone pieces! Interestingly simple and
devilish metaphor i think because if that was applied to science instead of
patent protection, the sharks leeching on the system and market wouldn't
raise the cost of products and taxes to support the bureaucracy behind.
That's just an iceberg tip in an artic ocean...

Try this... put this in a button:

on mouseUp
  put "Call Mom,Buy groceries" into tSubjects
  put "3" into tPriority
  
  put "tell application `iCal`" & cr & \
  "copy `"  & tSubjects & "` to TheItems" & cr & \
  "set AppleScript's text item delimiters to {`,`}" & cr & \
  "set TheItems to text items of TheItems" & cr & \
  "repeat with m from 1 to (count of TheItems)" & cr & \
  "set the NewToDo to make new todo at the end of the todos" && \
  "of the calendar 1 with properties {due date:(current date)," && \
  "priority:" & tPriority & ", summary:(item m of TheItems)}" & cr & \
  "end repeat" & cr & \
  "end tell" into tAS
  
  replace "`" with quote in tAS
  do tAS as AppleScript
end mouseUp

This is how I work with AppleScript - I substitute left angle quotes for
real quotation marks while building the script and replace them with quotes
later, and I try to format it with the same line breaks as it would be if it
were being typed (note the \ line continuation characters).

Hope this gives you some insight on how to work with AppleScript in Rev...

Newbie find, search command reprise ...

[Alex Tweedly]

Earlier this week, it was said:

The filter command is the fastest method, but be careful as it is a
destructive search i.e. it deletes the liens that don't match, so copy
your original data into a variable, filter that and keep the original
intact.
and a few people said minor variations on this; summary of them being that 
"filter" was fastest, though not always most convenient.

Well, it ain't always so.
I ran into some performance issues with my latest app this evening - 
something that I expected to be almost instantaneous took a long time. I 
assumed it was just a bug, but eventually convinced myself it wasn't - it 
was just taking too long. So I looked more closely at the parts where I was 
using "filter" quite heavily.

Input data : 10,000 lines, 1.5 Mb; the lines are all much the same size.
Search data: fairly long strings (32 characters each).
Success rate: each string happens between 2 and 5 times in the input.
In this case, "filter" appeared to be really, horribly slow - so I came up 
with a simple benchmark to check it.

on mouseUp
  put the millisecs into tStartTime
  set the itemDel to TAB
  repeat 4 times
put gFiles into tFList
filter tFList with "*cb2f8d231f68c5d70b3e62ed0a3c4c8f*"
  end repeat
  put "took " & the millisecs - tStartTime && the number of lines in 
tFList & cr & tFList & cr after msg

  put the millisecs into tStartTime
  put empty into fList
  repeat 4 times
repeat for each line L in gFilesput gFiles into tFList
  if  "cb2f8d231f68c5d70b3e62ed0a3c4c8f" is in L then put L & CR after 
tFList
end repeat
  end repeat
  put "took " & the millisecs - tStartTime && the number of lines in 
tFList & cr & tFList & cr after msg

The first version took 800 msec, while the second one took less than 1 msec.
I thought it must be because of the need to copy the input string to avoid 
destroying it (though I do need to do that in the real example), so I 
modified it to

  put gFiles into tFList1
  put gFiles into tFList2
  put gFiles into tFList3
  put gFiles into tFList4
  put the millisecs into tStartTime
  set the itemDel to TAB
  filter tFList1 with "*" & "cb2f8d231f68c5d70b3e62ed0a3c4c8f" & "*"
  filter tFList2 with "*" & "cb2f8d231f68c5d70b3e62ed0a3c4c8f" & "*"
  filter tFList3 with "*" & "cb2f8d231f68c5d70b3e62ed0a3c4c8f" & "*"
  filter tFList4 with "*" & "cb2f8d231f68c5d70b3e62ed0a3c4c8f" & "*"
  put "took " & the millisecs - tStartTime && the number of lines in 
tFList & cr after msg

Note that the time reported excludes the four copies; this still took 760 ms.
So at least in some (reasonable) cases, filter is far from being the 
fastest.  I suspect that the offset method Jacqueline suggested would be 
even faster - but since it was already less than 1 millisec I didn't pursue 
that thought.

Re: moving content of variable

[Ben Rubinstein]

I've made some progress here.  You may not be able to do copy, set, or get
to Revolution (though I suspect you should be able to); but you can do "do
script" and "evaluate".

I think you ought to be able to do something along the lines of

tell application "Revolution"
evaluate "global gBlah; get gBlah"
set x to the result
end tell

and hence copy the value of a Rev global variable to a variable in
AppleScript but I've not managed to do so.  Perhaps I just haven't
stumbled upon the right way to approach it.

Nor have I been able to use the equivalent of my old HyperCard trick,
invoking a function or handler to set or get a value.  I think this may be
because the default stack in this instance is not necessarily the one you
first thought of.

So it seems - at least without further research - that you're limited to
built in functions, and/or expressions which permit specifying a particular
stack.

However, what I have been able to do is read custom properties.  This works:

tell application "Revolution"
evaluate "the uTempStorage of stack \"MyStack\""
set x to the result
end tell

So it is at least possible to move a complex string from Revolution to an
AppleScript variable.  (Presumably it would also be possible to refer to a
field in the same way.)

I've not yet established a way to move a complex value back.   It is of
course possible to move one complex value back, in that Rev can get the
result of invoking an AppleScript; however, if the AppleScript needs to
return multiple values, you might have to combine them with some delimiter.
But I think we have at least the basics, even if it's not very elegant.

It would certainly be preferable to able to use set/copy/get.

(BTW,, if you get into this, one gotcha you should be aware of: in
AppleScript, 'return' is the character with code 13 ('\r').  In Transcript,
it is the character with code 10 ('\n', linefeed).  I have come to accept
that this was a reasonable design decision; but what I still find insane is
that Transcript has introduced a new constant 'CR', which has the same
value.  (CRLF, on the other hand, has the value '\n\r').  There is no
constant that has the value '\r'.  You'll need to do something like "replace
return with numtochar(13) in x' on the way into AppleScript, and "replace
numtochar(13) with return in x" on the way out.)

I haven't worked much with this, so I'm just guessing, but I bet you 
have to build a statement using "do". For example:

put "tell application" &"e& "HyperCard" "e&& "to copy" && 
theItems && "to theItems" into myScript
do myScript as AppleScript

I think that should work. Rev supports only the "dosc" appleevent for 
script executions.
:-) There is light at the end of this tunnel... but I can't tell if 
it's the exit or an oncoming train :-)

babbling on...
the 'tell application Hypercard' etc works just fine and it explains 
why HyperCard was launching when called from the script from 
Revolution, but at this point, HyperCard doesn't know anything about 
the variable because all the content is in Revolution. How do I get it 
out of Rev and into the applescript variable?

tell application "Revolution" to copy card field "theItems" to theItems
would be ideal.
and even if I wrote a script in Transcript and called it from 
Applescript as a dosc event, still doesn't transfer the content of the 
variable (?)

perhaps some kind of function, parameters, or clipboard thing
so I've tried setting the clipboarddata["text"], but the applescript 
balks at getting the clipboard, or I am not calling the applescript 
correctly.

The Transcript:
on mouseUp
put card field "TheItems" into TheItems
answer TheItems &&"1" -- just to test that it was working
repeat while last char of TheItems is return
delete last char of TheItems
end repeat
set the clipboardData["text"] to TheItems
--tell application "HyperCard" to copy variable "TheItems" to TheItems
-- was launching HyperCard in Classic, perhaps responsible for Rev's 
crashes
do card field "TheItems" as Applescript
--do the SendListToiCal of me as applescript -- don't know if this 
works as I am working with the card field script
put empty into TheItems
put empty into card fld "TheItems"
end mouseUp

 the Applescript:
display dialog the clipboard & " 2" --nada no response nothing
--set TheItems to the clipboard
--display dialog TheItems &" 3"
set AppleScript's text item delimiters to {return} --probably have to 
deal; with this 10/13 thing later
set TheItems to text items of TheItems
set AppleScript's text item delimiters to {","}
set TheItems to text items of TheItems
set AppleScript's text item delimiters to {""}

tell application "iCal"
	repeat with m from 1 to (count of TheItems)
		set the NewToDo to make new todo at the end of the todos of the 
calendar 5 with properties {due date:(current date), priority:3, 
summary:(item m of TheItems)}
	end repeat
end tell

 There is a crack in everything. That's how the light gets in.

Subject: Protecting your rev apps

Dear Revolutionaries

Is there any way to access something like a unique ID
number for the computer currently running the rev app?

It is my understanding that Intel starting giving all
CPUs a unique IDs a few years back, probably to help
MS combat software piracy. I don't whether other chip
makers do the same (AMD for example).

More generally, my question is:

Is there any way of obtaining or generating some kind
of unique ID for an individual computer, for licensing
purposes. I have read a lot of discussion in the rr
archives about using crypto keys and hidden license
files and so on. It seems like getting the CPU ID
(perhaps through the Win API) would be like the best
way to do it.

I had another idea for this - if you write files to a
disk, the exact addresses and distribution of file
fragments will arguably be unique on anything except a
newly formatted disk. To get around even this
limitation, what you could do is use a random number
sequence to generate a whole bunch of random files of
differing lengths and to delete a random subset of
them and expand a random subset of the ones that
remain by a random number of bytes. The remaining
pattern of files on the hard drive would then act as a
kind of digital signature that you make a digest of
using their hardware addresses on the disk (sector and
block numbers) and their random contents. Even if
somebody copied all these files to another computer,
their distribution on the new disk would not be the
same and only by imaging the entire original hard
drive and outputting the result onto another drive,
could you reproduce this (unless you had access to
your hard drive at the hardware level and could write
bit sequences to specific sectors and blocks). You
might even be able to make this tougher to do by
incorporating the index of bad blocks for the original
drive, into the digest. Could such a dsik drive
fingerprint scheme be feasible (or maybe its already
been done)?

Replies to my this and to my original question would
be greatly appreciated.

Best

Gordon

I've had that panel of the Help documentation open for a few hours now. 
This is how I would have done it in Hypercard...

with TheItems as a global:
tell application "HyperCard" to copy variable "TheItems" to TheItems

Which object do I address the copy/set command? Revolution doesn't have 
the dictionary to Get, Set or Copy.
I haven't worked much with this, so I'm just guessing, but I bet you 
have to build a statement using "do". For example:

put "tell application" &"e& "HyperCard" "e&& "to copy" && 
theItems && "to theItems" into myScript
do myScript as AppleScript

I think that should work. Rev supports only the "dosc" appleevent for 
script executions.

This bears repeating. When I started experimenting with rev I
converted some of my old HC stacks with some trepidation, since they
made heavy use of externals to get the required speed from the math
calculations. I was pleased and muchly surprised to find that rev's
internal math handlers were fast enough that I no longer needed to
spawn the tasks out to external handlers.

This sounds like what I want to do. I have a card field which holds a

put it into my Applescript variable, and the script will turn it into a 
comma delimited string, and follow through to iCal.

Yes. How do I pick up that string of literals. Applescript can't
set theItems to card Field "TheItems"
cause it doesn't know what it is. I need to set the variable from Rev's

 There is a crack in everything. That's how the light gets in.

Ooh, good question.  For some reason this hasn't come up for me so far in
Rev.  

I never discovered the technique you describe above for HyperCard; I used to
have a couple of functions (or perhaps a function and a handler) in the
stack script, called something like "setHCglobal" and "getHCglobal", and I
called those in an AppleScript.

But I've just tried that method in Rev now, and I get an execution error.
Presumably this is because as you've observed it doesn't have the dictionary
entries.

As it happens I've been able to get away so far with taking an applescript
that has a placeholder, and replacing the placeholder directly with
literals.  But obviously that only works for short values that don't have
any inconvenient characters such as returns or quotes.

I hope someone can up with a good answer to this.

Re: Network - Running A Standalone Application From A Network Server

You should probably look into PostgreSQL while you are at it too

and have been quite happy with it so far.

Greetings All,
I have written a standalone estimation package for our company using 
Revolution. About a half dozen people use the program. We tried 
putting the app on the company server, but it runs awfully slow. This 
whole process raises several questions:

1. Can a standalone stack, running on a server, actually be used by 
more than 1 person at a time without problems?

2. Related Question: When somebody opens this stack on the server. Is 
it actually running on the stack, or does the program run on the 
indivual's computer?

3. Related Question: When a person is working on an estimation 
project, all the values for that project are temporarily stored in 
various fields within revolution. This info is later saved on a 
server as a text file. Am I correct in assuming that if more than 1 
person is running the app off the server, if indeed this is possible, 
that it could create quite a mess?

4. Related Question: Since this is a new program, I am coming up with 
a new version at least twice a week. If having several people running 
the stack off the server is not possible, is there a way to quickly 
update the stack on everybody's individual computers with a newer 
version?

I hope all this makes sense.

RE: GM Scanner2.0e improvements

[MisterX]

Hi everyone,

The persons who downloaded the GM scanner should redownload it again. I've
improved it a bit more, added more explanations.

http://monsieurx.com/modules.php?name=Downloads&d_op=getit&lid=72

Believe it or not I had 3 controls with GM settings misbehave already! (fix
uploaded yesterday 5pm). 2 of these are my fault for copy pasting and
forgetting about GM settings. That copy paste GM settings feature is nice
but treachourous too, in fact, the third misbehaving control, the about
field, was resized correctly and somehow it resized itself wrong after!
buuh! Asking support for an update was not worth the trouble either! The
only right thing to do that I could find, was to write a fix myself now...

If you think it's not worth the trouble, I believe RunRev 2.5 stacks (or
previous) maybe affected if they use the GM. Im only trying to prevent
support accidents and development barriers. Hence GMScanner also gives you a
way to fix and explains how to avoid the bug.

It you have lots of stacks, i might add a folder and cards scanner for large
stack lists with filtered reports and auto-clearing/navigation. While it's
easy to do, it would cost you less programming time and effort to make a
small 5 euro donation to monsieurx.com to do it for you. ;)

The GM is great and this is not a recommendation not to use it - on the
contrary, it will save you hours of work and it's quite competent for
complex GUIs too!

Actually, I don't view this as a limitation at all.  It makes more

A single running instance of an App is a feature, not a limitation.

RE: Newbie: find, search command

[MisterX]

there's many ways actually...

you can use the LineOffset(string,container,startingline) function

but if you dont care what line it was, check out 

filter alist with "*xmas"

which is much faster and just returns those lines...

You could also repeat for each line, each item but that's not very efficient
after a few 100 lines...

moving content of variable

:-) I could do this with globals in HyperCard/Applescript. Revolution,

I think you'll be happy. After an initial unlearning curve -- you have

There are some issues if you imported your original HC stack. Crashes 
are often because the stack wasn't compacted well enough in HC before 
the import. Try going back to HC, and compact three times in a row, 
doing nothing else in between. Then bring the stack into Rev. I can't 
tell you how important this is. Stacks that crashed for me intially 
behaved fine after I did a triple-compact in HC first.

If the problem still occurs, try setting the hcAddressing of the stack 
to false. This turns off the HC-specific object referencing 
requirements, but also seems to help in some other ways. I'm not sure why.

Make sure you save the stack to disk immediately after bringing it into 
Rev. That seems to help too.

5) and I forget because I was interrupted by my daughter... h

If your XCMD doesn't work, you might try just issuing AppleScript 
commands to QuickTime Player. I haven't looked, but I suspect Player 
would support this sort of thing.

Ah! That makes sense.  Presumably Apple decided to place the same limitation
on (the GUI in) X that they had in Classic, to avoid scaring the horses (and
app developers who might have counted on the previous behaviour). Thanks for
clearing that up, Frank.

New to Revolution. May be a convert from HyperCard :-) Playing with 
the 30 day demo.

1) I have a button in my HyperCard stack -with a Hypertalk script- 
which has as its content a small applescript. So "do me as 
applescript" in the Hypertalk script executes. Where is the best 
place to put this snippet of applescript in my Rev Stack? Or, even 
better than compiling it again everytime, is there a better way to do 
this?

2) A question too about overhead. This is a small stack I want to 
run, basically one card that requests to a network and an applescript 
to send stuff to iCal. If I buy Dreamcard, I need to run it to access 
the stack. Upgrading to the Studio edition will allow me to build 
standalones... and it will just be stuff I'm running on this Mac, 
perhaps three or so stacks concurrently, OSX dual USB iBook. What is 
going to be the best use of Memory?

3) :-) I have had Rev quit a couple of times developing this little 
stack, as Rev pages in and out of RAM, I think. Maybe it's the calls 
to the applescript, which seem to launch HyperCard in Classic. So I 
need to get that applescript up to where I can deal with it.

is an AppleEvent thing, I think.

You may want to check out the Enhanced QuickTime External at

where's my blinking cursor?

[MisterX]

Hi everyone,

As you know, I work in weendoz 2K.

In some fields you do see the cursor blinking, but when you have some links
in the fields, or keyup/down handlers in the script or styles on some other
occasions , the cursor doesn't blink at the current text insertion point
like my old apple ][ did!

Go figure where your cursor is now! Click again just to make sure each time
or start doing shift arrow moves which are a big productivity stopper if you
write a lot... After a few hundred times per document, it gets annoying
too...

Is there a bugzilla for this? Anyone know a solution? If I enter a bugzilla
will you vote for it? (otherwise, i wont - just kidding ;))

Regards,
Xavier

Probably not.  There may be a difference between operating systems 
here.  On
Mac (classic) an app can only be once; the file on disk corresponding 
to the
application is locked while the application is open.  On Windows (in
general) apps are loaded into (at least virtual) memory, and an app

Someone who knows what they're talking about may be able to give more 
detail
here.
An OS X program can have multiple running instances.  Additionally, 
Fast User Switching in OS X 10.3 allows several users to be logged in 
simultaneously on the same computer.  Having one user running a 
particular program does not prevent other users from running it at the 
same time.  It's partially due to the UNIX clone sitting under OS X.

Note that in general, trying to start a second instance of the same 
program within a single user login session from the GUI doesn't work: 
the behavior is the same as for OS 9.  But you can start a new instance 
from a terminal window just fine.


2. Related Question: When somebody opens this stack on the server. Is
it actually running on the stack, or does the program run on the
indivual's computer?
Not quite clear about your situation.  Two possibilities:
- there is a standalone on the server.  User has a share mounted from 
the
server, and launches the standalone from that network drive.  In that 
case,
it's running on the individual's computer; but it may be still 
accessing the
network drive (the operating system may not simply load everything 
into the
memory of the user's computer, it may still read some parts off the
(network) disk).
- there is a stack on the server, and the users have either the 
revolution
app, Dreamcard Player, or a simple 'launcher' standalone on their 
machines.
In this case, it's simpler; the app (whichever of the three) is 
running on
the user's computer: when the app opens a stack from the server, the 
whole
stack is read into memory (on the user's computer).

3. Related Question: When a person is working on an estimation 
project,
all the values for that project are temporarily stored in various
fields within revolution. This info is later saved on a server as a
text file. Am I correct in assuming that if more than 1 person is
running the app off the server, if indeed this is possible, that it
could create quite a mess?
Fields within a stack shouldn't be a problem.  This always takes place 
in
memory, which will always be on the user's computer.  (I'm assuming 
you're
not doing anything exotic like Citrix in all of the above, btw.)

When you save the data to the server, you obviously need to take 
precautions
against one user overwriting another user's data, or one user being 
locked
out by another.
In other words, if the same file is always used, you've got some 
potential issues.  If a different file is used each time (or for each 
user, perhaps), there shouldn't be a problem here.


4. Related Question: Since this is a new program, I am coming up with 
a
new version at least twice a week. If having several people running 
the
stack off the server is not possible, is there a way to quickly update
the stack on everybody's individual computers with a newer version?
I don't think the stack off the server should itself be a problem.
Revolution, or any standalone built round it's engine, will read a 
stack
into memory completely and operate on it there.  Problems may be if 
you're
not talking about a stack off the server, but about a standalone off 
the
server; and when it comes to saving data.

In terms of quickly updating the stack, you can build a 'shell' 
standalone
which doesn't do much except start up, and open a stack containing all 
the
good stuff of your app.  (These are sometimes referred to as 'splash 
screen'
standalones, since they often display a splash screen and then pretty 
much
hand over to the stack with the real stuff.)  Depending on your setup, 
this
could be a stack loaded each time off a file server; a stack loaded 
each
time from a web server; or a stack loaded from a local copy, with some
provision to check for updates, and download and replace the local 
copy.

Re: mySQL Query... need some help

[Frank D. Engel, Jr.]

Also, if your field is accepting user input, be careful about 
"escaping" the strings.  Otherwise, if the user inputs text with a 
quote delimiter (') in it, the query may fail in the database, or give 
unexpected results.  Run each text field you aren't absolutely sure of 
through a function something like this:

function quoteString inText
  put inText into x
  replace "'" with "''" in x
  return x
end quoteString
Now you are looking at something more like:
put revDataFromQuery(,,databaseID, "SELECT * FROM mybuddies WHERE 
FirstName = " & quoteString(field "myQuery"))

On Dec 17, 2004, at 5:05 AM, Ben Rubinstein wrote:
on 17/12/04 3:58 am, docmann wrote
on mouseUp
  get revDataFromQuery(,,"SELECT * FROM mybuddies WHERE FirstName =
field 'myQuery'")
end mouseUp
I can see two issues here (I won't say that there may not be other 
ones!).

The first one is that you need at least two parameters to
'revDataFromQuery': database id, and SQL query.  You've got the SQL 
query,
but not the id.  But I'm guessing you may have just left that out of 
the
message?  Anyway, you need to open the database before you can call
'revDataFromQuery': see revOpenDatabase for more information.

The second problem is that the query string passed as a parameter to
'revDataFromQuery' is actually passed directly to the database, in 
this case
MySQL.  So MySQL gets this query:

SELECT * FROM mybuddies WHERE FirstName = field 'myQuery'
But MySQL doesn't know anything about your Revolution fields.  So you 
need
to get the data out of the Revolution field before passing the query to
MySQL.  You could do something like this, just using Transcript's 
standard
string concatenation operator:

  put field "myQuery" into tName
  put "SELECT * FROM mybuddies WHERE FirstName = '" & tName & "'" into 
tSQL
  get revDataFromQuery(,, iDatabaseID, tSQL)

That way, if the field contains "Bob", then the variable tSQL will be 
set to
(and MySQL will get):

   SELECT * FROM mybuddies WHERE FirstName = 'Bob'
Because this is quite a common pattern in making queries from 
databases -
most of the query is hard wired, but part is dynamic - revDataFromQuery
includes a special feature to make this more convenient.  The string 
you
pass to revDataFromQuery can contain placeholders, which 
revDataFromQuery
fills in from variables, the names of which are passed in as additional
parameters.  In this simple case, it's hardly simpler, but it can be 
useful
in more complicated cases.  The following code will send exactly the 
same
string to MySQL:

  put field "myQuery" into tName
  put "SELECT * FROM mybuddies WHERE FirstName = ':1'" into tSQL
  get revDataFromQuery(,, iDatabaseID, tSQL, "tName")
(Note that the name of the variable holding the value to be 
substituted for
the placeholder is passed, rather than the value - unusual in 
Transcript,
and slightly confusing.)

But one to thing watch re XCMDs; Rev implements the original (or strictly

so that they tested if a particular function was available; but as far as I

the right thing in terms of supplying a polite response, but many (most?)
XCMDs don't check it properly, and crash.  If you have access to the source

a bunch of mine were just using some convenience functions like StrToRect,

checking), so it was trivial to replace these calls).
Well said.
It may be worth noting that while more than a dozen apps once supported 
the HC 1.x XCMD interface, the HC2.x interface was so steeped in 
HC-specific structures that only HC itself ever supported it.

More importantly, most of the things folks had to resort to externals to 
accomplish in HC are built in with Rev, so with a couple of lines of 
revised scripting you can ditch those externals and have the 
functionality you're looking for on all platforms.

Since I first started working with this engine in 1997, I've only used 
one external -- written for Windows, which has since been replaced by 
native commands.  Everything else was replaced with Transcript.

Re: Newbie: find, search command

Yes, but a cr at the end will show a blank line at the end of a field.  
Remember that list boxes are fields, and the selectable lines are lines 
of text from the field.  Since you can hit return/enter and add a blank 
line at the end of the field and have it displayed, you will also see a 
blank line at the end of a list box.

The original poster specifically stated that he wished to display these 
results in a list box (which is a field), so this is definitely an 
issue for him.  Trust me, it took me a while to work this one out 
myself, and I've been using something similar quite heavily (although I 
let PostgreSQL do most of my sorts and searches for me -- I just format 
the results...)

Come on in, the water's lovely.  I am a deep, deep, HyperCard loyalist;
"Bill Atkinson is my hero" t-shirt worn to shreds; will always bleed in one
colour, etc.  Revolution is unquestionable the onlie true descendant;
incorporating just about everything that was good about HyperCard, with some
really fantastic advances.  I used RealBasic for a few years, and there are
some nice things about that product, but overall I find Revolution
infinitely better.  We're still dealing with IDE issues, but getting there;
the engine is very solid; and most importantly the development team is
excellent.

No alternative to compiling it again everytime - ie Rev, like HyperCard,
simply supports the 'do x as applescript' construction.  Best place to put
it?  Every object in Rev - stack, card, group, field, button, etc - can have
unlimited custom properties.  So no need to store this sort of thing in the
script anymore (effectively the only custom property available in HC).  So
put the applescript into a custom property called eg "uAppleScript", and
then eg "do the uAppleScript of me as applescript".

Note sure it makes much odds; if you can make it work with Dreamcard Player,
you should be able to use that to run your stacks without the memory
overhead of the IDE.

Hmpph.  I use AppleScript from Rev quite a bit, never does me any harm.  Not
necessarily communicating with Classic apps, though I'd have said I do

If you can make it reproducible - and even if you can't, but can give a good

I know nothing about MIDI.

But one to thing watch re XCMDs; Rev implements the original (or strictly
speaking, I think, the 1.1) XCMD API; but not the subsequent enhancements
(most of which came in with HC 2, IIRC).  In theory, XCMDs could be written
so that they tested if a particular function was available; but as far as I
know, few if any ever did.  If an XCMD makes an unsupported call, Rev does
the right thing in terms of supplying a polite response, but many (most?)
XCMDs don't check it properly, and crash.  If you have access to the source
code of the XCMD, you can very likely code round the missing calls (I found
a bunch of mine were just using some convenience functions like StrToRect,
which it weren't in the earlier API (and blush, of course I wasn't
checking), so it was trivial to replace these calls).

So first point, save before you test XCMDs, you might crash; secondly, test
them hard!

Good luck, have fun.

Applescript error?

[doug rogers]

Begin forwarded message:
From: doug rogers <[EMAIL PROTECTED]>
Date: December 16, 2004 8:38:15 PM EST
To: [EMAIL PROTECTED]
Subject:
New to Revolution. May be a convert from HyperCard :-) Playing with 
the 30 day demo.

1) I have a button in my HyperCard stack -with a Hypertalk script- 
which has as its content a small applescript. So "do me as 
applescript" in the Hypertalk script executes. Where is the best place 
to put this snippet of applescript in my Rev Stack? Or, even better 
than compiling it again everytime, is there a better way to do this?

2) A question too about overhead. This is a small stack I want to run, 
basically one card that requests to a network and an applescript to 
send stuff to iCal. If I buy Dreamcard, I need to run it to access the 
stack. Upgrading to the Studio edition will allow me to build 
standalones... and it will just be stuff I'm running on this Mac, 
perhaps three or so stacks concurrently, OSX dual USB iBook. What is 
going to be the best use of Memory?

3) :-) I have had Rev quit a couple of times developing this little 
stack, as Rev pages in and out of RAM, I think. Maybe it's the calls 
to the applescript, which seem to launch HyperCard in Classic. So I 
need to get that applescript up to where I can deal with it.

4) And the 'request from server' gives me back a -1701 error , which 
is an AppleEvent thing, I think.

5) and I forget because I was interrupted by my daughter... h 
you can't help me with that :-) Oh! MIDI! I have another stack which I 
would like to work on which depends on an xcmd (XCMD?) which does a 
call to Quicktime to export out a MIDI file. Anyone working on this 
kind of stuff?

There isn't much that you can do to deliberately crash the

I need a web server for a private LAN. It would be great to use Rev for

The client and the server we both created before André released

Probably not.  There may be a difference between operating systems here.  On
Mac (classic) an app can only be once; the file on disk corresponding to the
application is locked while the application is open.  On Windows (in
general) apps are loaded into (at least virtual) memory, and an app
corresponding to a file on disk can be open multiple times.  On MacOS X I'm
not sure; I know that an application writing to itself, possible on Mac
Classic but not on Windows (which corresponds to their respective positions
as to whether the running app uniquely owns the file it sprang from) is not
possible on X; however, it doesn't appear that an X app can be open twice.
Someone who knows what they're talking about may be able to give more detail
here.

Not quite clear about your situation.  Two possibilities:
- there is a standalone on the server.  User has a share mounted from the
server, and launches the standalone from that network drive.  In that case,
it's running on the individual's computer; but it may be still accessing the
network drive (the operating system may not simply load everything into the
memory of the user's computer, it may still read some parts off the
(network) disk).
- there is a stack on the server, and the users have either the revolution
app, Dreamcard Player, or a simple 'launcher' standalone on their machines.
In this case, it's simpler; the app (whichever of the three) is running on
the user's computer: when the app opens a stack from the server, the whole
stack is read into memory (on the user's computer).

Fields within a stack shouldn't be a problem.  This always takes place in
memory, which will always be on the user's computer.  (I'm assuming you're
not doing anything exotic like Citrix in all of the above, btw.)

When you save the data to the server, you obviously need to take precautions
against one user overwriting another user's data, or one user being locked
out by another.

I don't think the stack off the server should itself be a problem.
Revolution, or any standalone built round it's engine, will read a stack
into memory completely and operate on it there.  Problems may be if you're
not talking about a stack off the server, but about a standalone off the
server; and when it comes to saving data.

In terms of quickly updating the stack, you can build a 'shell' standalone
which doesn't do much except start up, and open a stack containing all the
good stuff of your app.  (These are sometimes referred to as 'splash screen'
standalones, since they often display a splash screen and then pretty much
hand over to the stack with the real stuff.)  Depending on your setup, this
could be a stack loaded each time off a file server; a stack loaded each
time from a web server; or a stack loaded from a local copy, with some
provision to check for updates, and download and replace the local copy.

Network - Running A Standalone Application From A Network Server

[John Miller]

Greetings All,
I have written a standalone estimation package for our company using 
Revolution. About a half dozen people use the program. We tried putting 
the app on the company server, but it runs awfully slow. This whole 
process raises several questions:

1. Can a standalone stack, running on a server, actually be used by 
more than 1 person at a time without problems?

2. Related Question: When somebody opens this stack on the server. Is 
it actually running on the stack, or does the program run on the 
indivual's computer?

3. Related Question: When a person is working on an estimation project, 
all the values for that project are temporarily stored in various 
fields within revolution. This info is later saved on a server as a 
text file. Am I correct in assuming that if more than 1 person is 
running the app off the server, if indeed this is possible, that it 
could create quite a mess?

4. Related Question: Since this is a new program, I am coming up with a 
new version at least twice a week. If having several people running the 
stack off the server is not possible, is there a way to quickly update 
the stack on everybody's individual computers with a newer version?

I hope all this makes sense.
Kind regards,
John Miller

Re: mySQL Query... need some help

[Ben Rubinstein]

> on mouseUp
>   get revDataFromQuery(,,"SELECT * FROM mybuddies WHERE FirstName =

> end mouseUp

I can see two issues here (I won't say that there may not be other ones!).

The first one is that you need at least two parameters to
'revDataFromQuery': database id, and SQL query.  You've got the SQL query,
but not the id.  But I'm guessing you may have just left that out of the
message?  Anyway, you need to open the database before you can call
'revDataFromQuery': see revOpenDatabase for more information.

The second problem is that the query string passed as a parameter to
'revDataFromQuery' is actually passed directly to the database, in this case
MySQL.  So MySQL gets this query:

SELECT * FROM mybuddies WHERE FirstName = field 'myQuery'

But MySQL doesn't know anything about your Revolution fields.  So you need
to get the data out of the Revolution field before passing the query to
MySQL.  You could do something like this, just using Transcript's standard
string concatenation operator:

  put field "myQuery" into tName
  put "SELECT * FROM mybuddies WHERE FirstName = '" & tName & "'" into tSQL
  get revDataFromQuery(,, iDatabaseID, tSQL)

That way, if the field contains "Bob", then the variable tSQL will be set to
(and MySQL will get):

   SELECT * FROM mybuddies WHERE FirstName = 'Bob'

Because this is quite a common pattern in making queries from databases -
most of the query is hard wired, but part is dynamic - revDataFromQuery
includes a special feature to make this more convenient.  The string you
pass to revDataFromQuery can contain placeholders, which revDataFromQuery
fills in from variables, the names of which are passed in as additional
parameters.  In this simple case, it's hardly simpler, but it can be useful
in more complicated cases.  The following code will send exactly the same
string to MySQL:

  put field "myQuery" into tName
  put "SELECT * FROM mybuddies WHERE FirstName = ':1'" into tSQL
  get revDataFromQuery(,, iDatabaseID, tSQL, "tName")

(Note that the name of the variable holding the value to be substituted for
the placeholder is passed, rather than the value - unusual in Transcript,
and slightly confusing.)

Hope this helps,
