Possibly one:  have you started using the new "private" keyword?

article about these topics:

Functionally (all puns intended), "command" is synonymous with "on".

"Command" was added to distinguish between message handlers and  
commands, though that distinction is stylistic; AFAIK they can be

Possibly one:  have you started using the new "private" keyword?

E.g.:

private function EmpName
  return fld "FirstName" && fld "LastName"
end EmpName

By specifying a command or function as "private" means it can only be 
accessed by other handers in the same script.


This has two benefits:

1. It helps keep some handlers from being called, things like internal 
utility functions in a library stack.


2. Speed:  being available only to the local handler, they trim a fair 
bit of the message-passing overhead.  While the time to call both a 
private and public handler is too small to be noticeable in a single 
call, access time to private handlers benchmark about 30% faster, so for 
frequently-accessed handlers it can be useful.

Limit Photo Size on Upload

[Sivakatirswami]

Thanks to Sarah's wonderful example I'm building a little photo uploader.
( I don't understand all the parsing of the multipart form data, 
exactly, but enough to customize

for my needs...)

I'm worried about abuse... maybe too paranoid... I don't know, but I 
would like to limit file size of uploads to 2.5 MB photos.


When do we do that?  I don't think a file browser
(  ) knows how big the file 
is to actually stop the upload...


so you have to handle it *after* receiving the post, right?

if $_POST_RAW is not empty then
# includes headers and filename and caption of course but no need be too 
precise


 if len($_POST_RAW) > 2636822 then

 # exit out of processing the post
 # and return some response to the user "File Too Big."

have I got this right?

command enableScrollbarIfNeeded pFldName

[jim sims]

In the dictionary user notes for formattedheight, the word "command"  
is used where "function" might be used.


Can someone please explain the significance of that to me? Is it  
different from a function?


---
I use the formattedHeight property in a handy routine to turn on/off  
scrollbars as needed. Just call it every time you change the content  
of a field.



command enableScrollbarIfNeeded pFldName
   if the formattedHeight of fld pFldName > the height of fld  
pFldName then

  set the vScrollbar of fld pFldName to true
   else
  set the vScrollbar of fld pFldName to false
   end if
end enableScrollbarIfNeeded

Hi,

Does anyone on this list know, if there are problems with the pdf
dictionary of Revolution on ebook readers.


I have a Sony 700 and it reads PDFs. If the PDF is an image, you can 
resize it to any scale and then scroll it by moving the image around the 
screen. If the PDF has flowable text, then the text will display as 
pages on the screen without having to resize it. You can search and 
annotate with the Sony 700. You can also set the text size to your 
preference. The Sony eReader does not have an internet connection, but 
I've never missed it. I load all my books from my Mac using the free 
software Calibre, which will convert almost any format to any other 
format, including Sony's. It will also convert PDFs to native text 
documentation.


I chose the 700 because I wanted a backlight, but the 505 is good if you 
read mostly in daylight. I don't know if the 505 accepts PDFs directly 
but Calibre supports the 505, so it can convert PDFs if you need to.


I just tried converting the Rev User Guide from PDF to Sony's "lrf" 
format, and it worked fine. It would also have worked on the Sony 
without conversion.


I've been using ebook readers for years, and I love them. My last one 
was worn down to the metal before I gave it up, I'd worn off all its 
skin. I'm a strong advocate for saving trees, and I like the convenience 
of being able to carry around hundreds of books in a device that is only 
a few ounces.

I have heard rumors (on the Kindle boards)  that at an international

Yes, I believe keyword searching is also not possible.  I KNEW there  
was a reason I had my Rev Dox on the DX but wasn't using them much.   
Or maybe that's just  because I haven't had time to use Rev at all

I have the Kindle 2, Kindle DX and used to have a Sony 505.

I would recommend using the Kindle DX, since it will give you nearly  
full size display of your PDF (albeit as a graphic PDF, not a reflowed  
text PDF).  I've tried the Sony 505 (same size screen as 600) but PDFs  
were so small I couldn't read them.  Same problem would be present if  
the Kindle 2 were capable of native display of PDFs (without  
conversion to AZW)--and I can't recall offhand if it even can.


Long story short, the only thing that does this adequately at present  
is the Kindle DX.  The only downside to reading PDFs on the DX is that  
the page is displayed as a graphic not as reflowing text, so can not

No, it doesn't. The docs for it say

downloads.

When you do, e.g., put URL ("file:abc.txt") into temp
control doesn't return to you until the put is complete.

Re: search for regular expression in text and put the results into an array

[Michael Kann]

The first script that got away didn't count the frequency correctly. This one I 
hope does so. I also noticed that the other one referred to teams in the 
scripts and restaurants in the data. I guess I got hungry halfway through the 
project. I also changed fld "a" to fld "input" and fld "b" to fld "output"

I took out the part where it lists the restaurants as they appear in the raw 
data. Now you only get the frequency, which was the original intent. 

Sorry if I caused too much trouble with the last script. I'll be more careful 
in the future.


on mouseUp

put fld "input" into v
put empty into fld "output"

put "" into  aTag
put "" into bTag

replace return with "*" in v
replace aTag with return in v

replace bTag with "@" in v
filter v with "*...@*"

set the itemDelimiter to "@"

repeat for each line curLine in v
put item 1 of curLine into curRestaurant

Would you count the number of lines, multiply by row height, and use  
this as the "formatted grid height", and resize the height of the  
group to this number?

Revolution Media 4.x and Revolution Player 3.x

[Dom]

As a former user of Revolution Media 3.x, I used Revolution Player to
run stacks without launching the development environment...

I am wondering if I still can use the old Revolution Player (3.x) to run
stacks created with the new Revolution Media 4.x?
