Try:

  send "arrowKey" && quote & "down" & quote to fld "fileList"

But personally if there is a better way, like to activate the same handler
that is activated when "arrowkey down" is triggered, that would be best,
IMHO...

Loading Application into Memory

[Steven Axtell]

I am writing a textbook-like application that consists of text and JPEG 
figures.  The total size of the application is about 500 KB.  When I launch the 
application, the first card comes up fast.  When I select a button to bring up 
a second card, there is a fair amount of delay (about 2 seconds on a Windows 
Pentium III, 1 GHz, 512 MB machine) before the second card comes up.  It's as 
though the application is loading into memory at that time.  After that, all of 
the cards come up fast.  What can I do to get the application to load into 
memory at launch?  Also, what would I need to do to show a card briefly while 
the application is loading into memory?

Thanks,
Steve Axtell

Sending ArrowKey("down")

[Sivakatirswami]

I have an arrowkey handler in a list field. when the user arrows down, 
stuff happens...


I would like to be able to pass that arrow key down from a field  but i 
can't get it to work:


the idea is: someone is typing in this field and when they are done, 
they hit tab and the arrowkey msg is sent to the list field.


on tabkey
 send arrowkey("down") to fld  "fileList"
end tabkey


doesn't work

on tabkey
 send arrowkey(down) to fld  "fileList"
end tabkey

also doesn't work.

The field is not in a group, there is no group on the card
and thus the field does not have tabbed behavior explicitely set,
but still if I tab from the field it goes to the next field on the card.

But the tabkey msg is sent, because  I do get  an error message say
"error in function: arrowkey("down")

The docs say:

"  Note:  Sending an arrowKey message does nothing unless there is an 
arrowKey handler in the message path. This is a difference from 
HyperTalk's handling of the arrowKey message."


So, it appears like it should work, but there's no example in the docs 
on just exactly how to send an arrowKey message, which one assumes must 
require a parameter to indicate which of the  four arrow keys one is 
emulating.


I'm missing some thing simple

TIA

Re: finding repeating patterns

[jbv]

for those interested, here's something much faster :

on mouseUp
  set cursor to watch
  lock screen
  put fld 1 into myST
  put number of chars of myST into n
  put "" into myL
  set the casesensitive to true
  put 1 into k
  repeat while k<=1000
repeat with i=100 down to 6
  put k+i-1 into b
  get char k to b of myST
  put myST into a
  replace it with "" in a
  put ((n - number of chars of a) / b) into c
  if c>=2 then
put it & tab & c & cr after myL
add b-1 to k
exit repeat
  end if
end repeat
add 1 to k
  end repeat
  put myL
end mouseUp

Re: finding repeating patterns

[jbv]

Dar,

I came up to something similar... Here's a (very raw and quite slow) first 
approach
(it checks only groups of 6 to 20 chars) :

on mouseUp
  set cursor to watch
  lock screen
  put fld 1 into myST
  put "" into myL
  set the casesensitive to true
  repeat with k=1 to 1000
repeat with i=20 down to 6
  put k+i-1 into b
  get char k to b of myST
  put myST into a
  replace it with "" in a
  put ((number of chars of myST - number of chars of a) / b) into c
  if c>=2 then
put it & tab & c & cr after myL
exit repeat
  end if
end repeat
  end repeat
  put myL
end mouseUp

This brute-force method came to my mind.  Decide on a min and max  
length of patterns.  Try all possible substrings.  (Outer loop is  
start position, inner loop is end char based on min & max length.   
With each one check in an array.  If not there put 1 otherwise  
increment.  Look for counts greater than 1.


If the repeating pattern must come right after the starting pattern,  
then this does not apply.  In that case, just look for the repeats of  
the substring after the trial string.  The problem is that "xaxaxaxa"  
would be counted as a repeating of "xa" and a repeating of "xaxa".

Re: finding repeating patterns

[jbv]

well, I just realized that my question isn't very clear...

I DON'T WANT to find how many times pattern "ta" appears
in string "tatata" (for instance)...

What I want to find is : is there any repeating pattern of chars
in any string, which are they and (that's easy) how many times
each pattern appears in the string...

The Amazon [so-called] Web Services just dazzle me.  Storage, queues,

Fwd: Question: MacOS X Bundled Apache Server or Embeded Web Server?

[Pierre Sahores]

Katir,

I forgot to precise, in the previous mail, that the tasks queued to  
the Rev deamon is'nt managed by the Rev deamon it-self (Rev is not so  
good in about this) but by Apache+PHP, so the Rev deamon always just  
know about one task after the other and never twice at once. Because  
Apache does this part of the job in multi-thread mode, the result is  
for us that the global server-side process "Apache+PHP+Rev" works  
just alike a 100% multiprocess system would do with just a small  
difference : it works then time faster than the Tomcat, JBoss or  
Websphere based solutions...


Best,

Pierre

Hello Katir,

In theory such a process will block your framework for 10 seconds  
as you expect. In practice, there is, for sure, a way we can design  
the entiere "n-tier" process your are thinking about to have the  
blocking part of it on the client-side part of the solution (AJAX  
xmlhttprequest object calls if the client app is a webbrowser, Rev  
scripting if the client-side app is a Rev one), so you will never  
need to slow-up and breake your server-side queue of tasks. In this  
case, the fact that Rev is not multi-threaded will never be a  
problem because, even if some ones can doubt of this, J2SE deamon  
are running up to teen time slower than Rev deamons (Linux and OSX) :


J2SE supports 3 threads max at once while Rev is queuing each task  
= 3 * 10 times unit for J2SE and, only, 3 * 1 times under a Rev  
server-side deamon to have the same quantity (and quality !) of  
queries served to the clients. As you can expect, even if Rev is  
not multi-threaded, the work will be well done by Rev because its  
ablity to speed-up the responses to the queue of requests...


If you give me some more details about the process, you are  
thinking about, i'm sure we will be able to design the solution  
without having to manage synchronious blockings on the server-side.


Kind Regards,

Pierre

You can also define a nice icon for the CD by putting the ico file on  
the root level

of the CD-Rom and adding these line to the file:

icon=nice_icon.ico
open=name_of_your_app.exe

The icon is of course optional.

There was a trick on Mac to autostart CDs. I don't know if this is

This anti-feature is no more available on a Mac!

Since one of the rare Mac virii (the so called "autostart virus, I  
think it was programmed
in HyperCard?) used this leak in earlier days, Apple completely  
diabled this feature.


Unfortunately, and since CDs do NOT appear on the windows desktop  
like they do on the Mac,

the autorun feature is almost a MUST for windows distribution on CD.

Most windows users are completely lost and do not know what to do  
without this "feature",

which of course a heartfelt invitation for malicious code :-)

icon=harmless_kitten_or_something.ico
open=evil_app_that_will_erase_the_complete_harddisk.exe
