Re: background images

[Tim Selander via use-livecode]

Thanks, Peter.

I added a little opencard script to load the image for each card, 
which is fine and solves the immediate problem.
But I was quite certain that in the past, I had a stack, with an 
image control in a background that would keep a unique image for 
each card without scripting. I must be dreaming/getting forgetful 
in my old age!

That’s where a image that is not part of the group is useful; it’s only on that 
card. Otherwise you would have to set the background image dynamically on 
preOpenCard based on stored data about that image/card combination.

The table name is "contactInfo" and the list of the table's fields is in the 
paranthesis.

The VALUES(:1,:2  syntax is something I haven't seen before. I assume that 
you need as many numbers as you have fields?

You say to use variables, and I am assuming in the "revExecuteSQL" line. Is that correct? 
I tried the list of variables both with the quotes you used, and without just to see. I also tried 
replacing the revExecuteSQL comman with revdb_execute. Both result in this error: {execution error 
at line n/a (External handler execution error: revdberr,syntax error) near "revdberr,syntax

I appreciate your taking the time to educate me.

Here an example :

put fld "name" into tName

put the label of btn "title" into tTitle
put fld "first_name" into fFirst_Name

put fld "address" into tAddress

put fld "citycode" into tCitycode

put fld "tCity" into tCity

Hi Tim,

That would be correct. To have a different image on every card, you could:

1. Have an image control that’s not part of the group on every card
or
2. Some other method of dynamically loading the image data into an image that 
is part of the group, such as on openCard:

put URL tURL into image “My Image" of this card

where tURL is a path to a local or remote file.

Player controls would use similar methods as above.

Re: Writing a UTF8 text file to server -- solved

[Tim Selander via use-livecode]

Just for posterity...

Tried many combinations of various commands opening the file 
as a binfile instead of a text file solved my problem


Changed:
open file vfile for utf8 text update

To:
open file vfile for binary update

At which point the same command:
write vdata to file vfile at end

properly saved the data as utf8/kanji to the file on the server.

All's well that ends well.

Re: Using the $_POST global in LiveCode server

[Tim Selander via use-livecode]

Thanks, Mike.

This seemed like a good hint/possible solution.

Another though has just occurred to me also..  If you use session
variables, you can store the search term in the session, and since the
browser will re-post on reload, if $_POST and your session variable contain
the same search term, its possible (likely?) that it was a reload rather
than a new search, then don't do the search. Not sure if this is helpful,

However, when I tried

and the server returned the error

file "/home/pba/public_html/lifelinesearch.lc"
  row 2, col 1:

This snippet is at the very top of the page, so row 2 is "start session."

Am I misundertanding the syntax of 'session'?

Thanks,

Tim

Using the $_POST global in LiveCode server

[Tim Selander via use-livecode]

Hi,

Is it possible to change, or even delete, the $_POST[] array in LiveCode 
server? I want to clear it after my script has pulled out the info it needs.


Or, maybe there's another way to skin the cat. I have a search page that 
returns a list of our online TV programs. But even if the page is 
reloaded, the previous search term is still "live" in the $_P, so the 
page returns the previously searched list of programs. If a user reloads 
the page, I want the page to come up with no program list until they 
enter a new search term.


Any pointers?

Thanks!

The problem you are having is that your text-file is UTF-8, but the engine
doesn't know that - you need to explicit decode it into a LiveCode string
using textDecode. You can then manipulate it as chars etc. correctly with
Unicode. That solves the 'getting data into livecode in the form needed'
problem.

The other side of the problem is the text encoding used when you do 'put'.
By default this is 'native' - by setting the outputTextEncoding at the
start, the engine will automatically encode any strings you 'put' with the
encoding specified.

Hope this helps!

Mark.

Re: UTF8 on LC server

[Tim Selander via use-livecode]

Hi Mark,

Here is the script. The files I'm using are 
bamboobabies.com/getjapanesetext.lc, and the text it is getting 
is bamboobabies.com/news.txt.


In the script, there are two lines reading the text file that 
I've taken turns commenting out


If you can give me any hints, it would be greatly appreciated.

Tim Selander








workbench



--This line loads readable japanese text, but putting char 500 to 
550 breaks beginning and ending kanji

put url "http://bamboobabies.com/news.txt; into vText

--When this line is used, none of the put text is readable
--put textDecode(url "binfile:bamboobabies.com/news.txt", 
"utf-8") into vText


put line 1 of vText

put ""

put char 500 to 550 of vText
 ?>

You should be fine using 'character' on any unicode text - it
uses the Unicode grapheme (specific name of 'character's as
human's 'think' of 'character's) breaking rules to find the
boundaries.

That being said, I think codepoint (from memory) should also be
okay on Japanese text as I don't think the Japanese/Chinese
scripts have any multi-codepoint characters - they just use
codepoints with value > 65535 for less used ideographs (the
'supplementary plane'). [ Korean script can be encoded with
Hangul, which *does* require the use of character as a single
Korean Hangul ideograph can be composed of up to three codepoints ].

The fact it is breaking on Japanese text in the way you suggest
makes me think you aren't textDecode()'ing your UTF-8 input files:

e.g.
put textDecode(url ("binfile:"), "utf-8") into tText

Without decoding as utf-8, the engine will thing your file is
'native' (single-byte encoded), so each byte of the file will be
seen as a separate character.

Internally the engine uses either single-byte or double-byte
encodings for strings (the latter being UTF-16) - which is not
user-visible, you just need to make sure that incoming data is
decoded correctly.

Can you share the code you are using to read in the text data and
code which is breaking on server?

Warmest Regards,

Mark.

P.S. 'word' in LC is still any sequence of non-space characters
separated by spaces, or any sequence of characters delimited by
quotes - it takes no account of the script of the text, nor
actual word-boundaries. If you want human-style word boundaries
then you should use trueWord (which uses the standard Unicode
word breaking rules).

Re: UTF8 on LC server

[Tim Selander via use-livecode]

Hi Kee and Alex,

The original documents I'm working with are UTF8, so that's that I've 
been using. So converting them to UTF16 is recommended? I'll try that.


Alex, desktop is version 8 something, and the server is the one 
installed on the on-rev host; can't remember what the key in $_Server 
for than info is, and Googling failed me this time...

LC Server serves pages with a default "Content-Type" header of:

That would prevent the display of Japanese characters.

Try putting:

UTF8 on LC server

[Tim Selander via use-livecode]

Hi,

In LC, if I have a field or variable in Japanese (double-byte) 
and get, say, the 5th character, it returns the correct 
double-byte character. But on LC server (on-rev hosting) 
"character" commands get single bytes, breaking the Japanese 
character turning it into gibberish.


Is there any way to get LC Server to handle double-byte 
characters the same way LC desktop does?

Parse that and voila, you have your info.

And this works fine in a button:

But this does not in the table field:

I always get "line 1 of field 3"  ()

  Kluge city to get the line from the selectedLoc, but that would indeed

Is it that in a table field, if only one "cell" is selected, the
selectedLine just does not compute?

Hi,

Editing a table field (not datagrid) and need to track the number 
of the line that is being edited. If I click into a new line, 
"selectionchanged" will let me figure out what line I'm editing. 
But if I hit return or tab to go to a new line, how can I track 
what line the cursor is in? Rawkeyups and downs are being sent, 
but I have been unsuccessful in trapping them in the table 
field's script.


Any ideas?

Have never written a CGI in my life but you got me thinking; a

So now my .lc script on my on-rev serve puts the url of the .php

FTP is probably not the best solution for this, for reasons too
numerable to list this morning.

But for the task as described, other simpler, more efficient, and
more secure alternatives exist:

Can you run a CGI on the server holding the MP3 files to obtain
that list?

Or, if they're within you're web root, can you use Apache's
directory listing?

My company gave up on hosting our email and website at on-rev.com <http://on-rev.com/> 
<http://on-rev.com/ <http://on-rev.com/>> back when they were having lots of

(gmoserver.jp <http://gmoserver.jp/> <http://gmoserver.jp/

Any ideas why the connection would be refused when coming from on-rev, but not 
LC desktop? Anyways around this?

Re: Goofy question #7234

[Tim Selander via use-livecode]

Hi Richmond

This works (both scripts in the button):
on mouseUp
put goRed()
end mouseUp

function goRed
set the backGroundColor of card 1 to red
end goRed

I think the general idea is that a function returns information. So 
date() returns the date. But just having a line "date()" in the script 
causes an error because you haven't told it what to do with the info 
being returned. So you need "put data()" and then the info will go to 
the message box.


Your function doesn't return any data. That's your choice when you write 
it. But the engine is still expecting a function to return info, so you 
still have to say "put" trigger the function.


You could write your function with a parameter:
function goRed foo
set the backGroundColor of foo to red
end goRed

Then call the function like this:
put goRed("card 1")
put goRed("card 3")
etc., and the one function can be used to turn both card 1 and card 3 
(and any other object you specify in foo) red.


Hope that helps.

Re: Messages sent while mouse is down?

Yes, that had occurred to me, but my explanation was too 
simplistic. While it is a Scrabble-esque game with tiles, the 
tiles are hexagons and are staggered on the board. (pic--

That still might be calculate-able, but is beyond my math skills!

For those who don't know the game, it had a solid screenful of
Scrabble-like lettered tiles. Click and drag the mouse through
adjacent letters to make words.

Without clicking, simply moving the mouse through the tiles
(fields) triggers mouseenter, mouseleave, etc. which makes it
easy to pick up the letters.

But when the mouse is down, it seems mouseloc() is the only thing
I can get. Using a variable what has all the field rectangles, I
can use the mouseloc() to ultimately identify the field under the
pointer, but it's too slow...

Does a moving mouse with the button down trigger any other
messages besides mouseloc()?

I see that Mike Bonner has already provided a solution which seems to do
what you want. But just in case there are other people out there who might
need a different solution, here's my stab at it…

If you have a "screenful of Scrabble-like lettered tiles", these "tiles"
are presumably arranged in a rectangular grid, with neatly aligned rows and
columns. If this is the case, the locations of the row-tiles are going to
be separated by X number of pixels, such that row-tile 1 has X-coördinate
A; row-tile 2 has X-coördinate (A + X); row-tile 3 has X-coordinate (A +
2*X); and so on.

Column-tiles will work similarly. Their locations will be separated by Y
number of pixels, such that column-tile 1 has Y coördinate B; column-tile 2
has Y coördinate (B + Y); column-tile 3 has Y coördinate (B + 2*Y); and so
on.

If the grid's horizontal spacing is identical to its vertical spacing, the
separation-values X and Y will be the same, of course. Given the fact that
pixels are not *necessarily* square, it would be imprudent to *assume* that
the grid's horizontal and vertical separation-values are identical, and I
will not make that assumption here.

So.

My solution to Tim Selander's problem completely ignores most of the
mouse[whatever] messages, depending strictly on mouseLoc. Like so:

local dX = 25 -- if the horizontal-spacing value is not 25, put the real
value here
local dY = 25 -- again, replace 25 with the real value as needed
local TimeSlice = 50 -- how often, in milliseconds, the code checks the
mouseLoc. adjust as needed for response time
local GridLocPulse

global GridCell = "1,1"

on GridLoc
   if (GridLocPulse) then send GridLoc to me in TimeSlice milliseconds
   put the mouseLoc into ThisLoc
   put (1 + (item 1 of ThisLoc div dX)) into item 1 of GridCell -- may need
tweaking to account for edge effects
   put (1 + (item 2 of ThisLoc div dY)) into item 2 of GridCell -- ditto
end GridLoc

on GridLocOn
   put true into GridLocPulse
   GridLoc
end GridLocOn

on GridLocOff
   put false into GridLocPulse
end GridLocOff

The above code can go into the script of the card where the tile-grid
lives.

Once every (TimeSlice) milliseconds, this code looks at the mouseLoc and
converts the mouse coördinates into grid coördinates, which are stored in
the global variable GridCell. GridCell being a global, its contents should
be accessible to any handler in any script which includes the line "global
GridCell".

It's probably a good idea to *not* have the GridLoc handler burning
clock-cycles *all the time*. Thus, the local variable GridLocPulse, and the
subsidiary handlers GridLocOn and GridLocOff. GridLocOn activates the
GridLoc handler, and GridLocOff turns GridLoc off.

Hope this helps…

Then all you have to do is hold shift and the loop will exit.

Phil and Mike, Thanks for your pointers -- both look like they

  set the itemDelimiter to "/"
  -- extract host IP address and file path from the URL
  put item 3 of pURL into tHost
  if tHost contains ":" then
put tHost into tSocket
  else
put tHost & ":80" into tSocket
  end if
  put "/" & item 4 to -1 of pURL into tPath
  -- build the command
  put "HEAD" && tPath && "HTTP/1.1" into tCommand
  -- build the http headers
  put "Connection: Close" & CRLF & \
  "Host:" && tHost & CRLF & \
  "User-Agent: Revolution (" & the version & ")" into tHeaders
  -- open the socket, write he request and read the response
  open socket tSocket
  write tCommand & CRLF & tHeaders & CRLF & CRLF to socket tSocket
  read from socket tSocket until CRLF
  put word 2 of it into tResultCode
  close socket tSocket
  -- return our interpretation of the result code
  return (tResultCode = 200)
end qrtHTTP_FileExists

It's working for me but now I can't re-find it so I can't

obviously an extremely bare example.  You'd want to make sure the get

addition, you would probably want to limit the requests to only allowed

From the lc side of things you could do something like this..


http://your.alternateserver.com/checkforfile.php?myfile=theFile.mp3;
if it is true then
   put "http://my.programserver.com/theFile.mp3>"
   else
   put "program not found."

Of course if you DO have lc on the program server you can do the same type
of check and "put" true or false just like you did with php.  (Also can be
done with javascript, asp, etc)

Hi Tim,

Here is a very simplistic way of checking for a file on your server. It

your server. You pass it a filename in the url and it tells you if the file

So the url would look something like this:

Using LC server to check for existence of mp3 on our web server?

[Tim Selander via use-livecode]

Hi,

On-rev.com hosting, using LC server to present a list of our 
AM/FM radio programs for people to listening to on-demand.


Out of a month's 20 programs, 3 or 4 might not get uploaded due 
to copyright issues, etc. Also, mp3's are not on the on-rev.com 
server, but another hosting service we use as well.


Filenaming is standardized, so I know the list of programs. I 
want to hit the server, if the mp3 files exists, present it as an 
program not available" message.


If I wanted to check on the existence of a small text file, it 
would be fast enough for me to just get it, put it into a 
variable and see if the variable has anything in it. But mp3's 
are too big, so too slow.


Locally, I would simply write "if there is a file 'filename'..." 
 -- what's the equivalent command for checking on existence of a 
file on a server?


Thanks in advance.
