Re: Data Persistence

[Mike Bonner via use-livecode]

Putting text into a field pro-grammatically doesn't fire the openfield and
closefield handlers so yes, you'd need to add code to your button.  You can
either write the code directly, or you can use send (or dispatch) and have
the field do it.. IE send "closefield" to field "whateverfield"...   But if
it were me, I'd just add the code to the button itself.

Actually, I'd probably have the code once, in the card or stack script that
accepts parameters like the long id of the field, data to be saved and
whatever else so that you have a single handler that will work for all of
your saves.

Something like

on saveIt pLongId,pText
-- code to save pText and associate it with control pLongId
end saveIt

Then you can do..
on closefield
 saveit (the long id of me),(the text of me)
end closefield

Or in a button..
on mouseup
put "Whatever text" into field "myField"
saveit (the long id of field "myField"),the text of field "myField"
end mouseup

Just some thoughts.

Version 7.1.0 doesn't seem to work.  (the version used by on-rev.)  Pretty
sure its been in this non-working condition for a while.  (again, my faulty
memory might be wrong)   I'll try and set up a test for later versions, but
pretty sure things were still working in the 6.x range of server engines.

Its been a while since I messed with sessions, but that looks right.  I
seem to vaguely remember that there is some version of LC server where
sessions is broken, but I can't recall for sure.  What version of server
are you running?   (IIRC sessions was implemented some time around 4.6.3?
And a later version was broken and later fixed)  I'll see if I can relocate
the info.

Re: Using the $_POST global in LiveCode server

[Mike Bonner via use-livecode]

I don't really understand what I've read yet, but I think what you're
looking for is Post/Redirect/Get (prg)  Basically.. Accept the post,
process it, redirect to another page without the post. (One example I read
basically placed the generated html into a session variable and displayed
it after the get, then cleared it from the session so that a reload
wouldn't show anything)

Lots of examples in php, not sure how to implement with lc.

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,
and not sure how to handle the back button either.

Re: Data Persistence

[Mike Bonner via use-livecode]

No, the memory db is in memory, the file db is still a file.  Also forgot,
you should probably quote the filename 'pathtofile.db' otherwise it gets
confused (unless you use a file with no extension.

The nice thing about this is you can have your nice persistent file db,
open a memory db, then do a create table main.tablename as select * from
attachedtable.tablename at which point you have the speed benefits of using
an in memory database.  Just gotta keep both updated if you make changes
that need to be persistent, but thats no different than loading an array,
and having to keep the disk based encoded array up to date with changes.
Faster if anything since you don't have to write the whole thing every time.

You have to declare it as a global in every script where you use it.   It

Sorry.. To elaborate, yes you can attach a disk based db to a memory db.
Then you use dot notation to specify which database you're working on.

So it would be a regular attach-- attach pathtodatabase.db as dbname
Then any place you would specify a table name it would be dbname.tablename

Re: Local images and the browser widget

[Mike Bonner via use-livecode]

Decided to try using the httpd library, and it seems to work pretty
nicely.  If you want to set up a very simple web picture viewer (VERY
simple) the following code is a working but minimal start.

local sBaseDir
on mouseup
   httpdstart "newrequest",,"My Picture Server" --start the server on
port 
   put specialfolderpath("desktop") & "/pics" into sBaseDir -- Set this to
the folder that contains your pictures
end mouseup

on newRequest pSocketId,pRequest -- handle requests
   if pRequest["resource"] is "/" then -- if the request has no filename,
give the directory index of jpg files. (I only coded for jpegs)
  put files(sBaseDir) into tFiles
  repeat for each line tLIne in tFiles
 put merge("[[tLine]]") & cr after tData
-- build up the response data for each file
  end repeat
  httpdresponse pSocketId,200,tData -- send the index
   else
  put "Content-Type: image/jpeg ;" into pHeader -- set the content type
to jpeg
  put URL("binfile:" & sBaseDir & pRequest["resource"]) into tData --
read the image file and pop it into tData (binary mode)
  httpdresponse pSocketId,200,tData,pHeader -- send the picture data,
200 ok code, and set the correct header for picture data
   end if
end newRequest

If your filenames/paths have spaces, you'd have to jump through some hoops
to get it to work, and your base path has that space in it, so not sure how
to get it working. Actually, nevermind.  If you change spaces in your
baseurl to "\ " it may work?  I couldn't make it work here (on windows)
despite trying a whole bunch of ideas, so I cheated and made sure there
were no spaces.

Re: Local images and the browser widget

[Mike Bonner via use-livecode]

If you just need to see the image, you can do it by changing your method..

Instead of setting the htmltext, it should work to set the url to  "
http://Users/steve/Dropbox/ITB%20pubEngine/tempMedia/99578
6d6-4429-4821-8b21-8e811289e12c.jpg"

I'm not expert, but I think there is some type of cross-domain security
thing interfering here.  A web page shouldn't be able to force access to a
file on your system due to security, unless the page originates with you.
And I THINK that directly setting the html basically means there is no base
domain, so it will refuse to show the image.  Again, not an expert, so i'm
just making a wag.
If you need more control, you can likely create an html file on the fly and
point your url to that, at which point you can use relative addressing for
your pictures.  So, if you created the html file with your code in the same
folder as your stack, you could then place..  into the file and it will likely work.

Another thing you might look into is running your own simple http server
(which LC now makes easy) so that you can set up a simple server and set
the url to http://localhost:8080/index.html  (or whatever port number you
wish, and again, use relative pathing.

Either of these 2 methods is easier than using long, easily mangled
absolute paths.   I haven't delved into the self run server yet, but I
suspect you can do interesting things with it. (Or use the old revhttpd
stack which I HAVE used, and know that it works really well and can do
awesome stuff too)

Re: set the filename of image bug?

[Mike Bonner via use-livecode]

If you think the stack is corrupted, you might send it to
supp...@livecode.com so they can look at it, and/or post a bug report and
include the stack there so that it can be looked at. (assuming there is
nothing sensitive in the stack)

Re: set the filename of image bug?

[Mike Bonner via use-livecode]

If it works for Klaus, and fails for you, it makes me wonder if something
has gotten munged in the imgUrl variable.

You might try putting an "answer imgUrl" (or use the variable inspector) to
confirm that everything looks right.

(worked fine for me too)

Re: Problem saving image for file

[Mike Bonner via use-livecode]

It's just how file systems work.  If the beginning character is / that
means it starts at the root of the file system.  Since you had already set
the defaultfolder, and wanted to go relative to there, you would just
specify the folder name/filename.  Or as I said, pre-pend a dot.   In fact,
2 dots .. stands for the next folder towards the root so you can do weird
things like dir ../../..  which will list the contents of a folder 3 levels
above the current.

You also don't need to actually set the defaultfolder, you could do as in
your example...

set the itemDelimiter to slash
get the effective filename of this stack
put tTempCrop into URL "binfile:" & item 1 to - 2 of it &
"/tempMedia/testimage.jpg"

In the case of the above you DO need the slash before tempMedia because
there is no trailing slash when you get item 1 to -2 of it.  But, item 1 to
-2 of it is a path starting from the root so you end up with an absolute
path rather than a relative path.  IE it would be something like
/home/username/desktop/mystackfolder/tempMedia/testimage.jpg

Re: Problem saving image for file

[Mike Bonner via use-livecode]

If you use the path /tempMedia that forces it to the root of the
filesystem and if there isn't a folder /tempmedia, it'll fail.  Either
leave off the preceding slash, or prepend it with a . <--(a dot) which
designates the current directory.

Re: Data Persistence

[Mike Bonner via use-livecode]

On the subject of sqLite/memory databases and preferences/data persistence,
rather than using an array, and doing the encode/decode stuff, would it
make sense to do the following..
1. open an empty in memory database
2. attach a disk based database
3. copy the required table(s) from disk base to memory base

At this point, for data reads you have a super fast sqlite in memory
database.  For updates, do a double update, both in memory, and disk.

It seems like this would be more efficient than re-encoding an array every
time there is an update and writing the whole thing out to disk each time,
rather than updating just whatever small change might need to be made to
sqlite.

The affects and requirements would be similar. Update the array, (1 update)
ecode and write to disk (second update)  vs update in mem sqlite, and
update attached sqlite database.

Does my thinking make sense?

Re: drawing a Barcode without a Barcode font

[Mike Bonner via use-livecode]

Not sure if it will work for your purpose, but as a test I created for
graphic lines, 1 narrow black, 1 wider black, duplicated them and set the
blendlevel of the copies so that they're transparent.

Grcs are named narrowB, wideB, narrowC and wideC (b for black, c for clear)

Then used the following code (and your example string from above with the
WWnNw stuff) to generate a barcode.

on mouseup
   put empty into tLast
   put field 1 into tChars -- the field with your wNnnW string
   set the casesensitive to true -- to differentiate case of course
   repeat for each char tChar in tChars
  switch tChar
 case "N" -- checks the char, and clones the matching bar.
--if its the first time through, places it at a
start location
-- then uses the id of the most recent bar for
placement purposes
clone grc "narrowB"
if tLast is empty then
   set the topleft of the last grc to 10,50
else
   set the topleft of the last grc to the topright of grc id
tLast
end if
break
 case "n"
clone grc "narrowC"
if tLast is empty then
   set the topleft of the last grc to 10,50
else
   set the topleft of the last grc to the topright of grc id
tLast
end if
break
 case "W"
clone grc "wideB"
if tLast is empty then
   set the topleft of the last grc to 10,50
else
   set the topleft of the last grc to the topright of grc id
tLast
end if
break
 case "w"
clone grc "widec"
if tLast is empty then
   set the topleft of the last grc to 10,50
else
   set the topleft of the last grc to the topright of grc id
tLast
end if
break

  end switch
  put the short id of the last grc into tLast -- the id of the most
recently placed bar
   end repeat
end mouseup

Spacing and line size might need to be tweaked, but it seems like this
would be relatively straight forward.

Re: Docker

Sounds like there is a need for a new Dropsock service so that socks can be
posted and shared freely. Or perhaps a bitSock system where those who are
advantaged can solve sock chain transactions, but it would require everyone
to set up a digital hamper to store any earned sock currency.   Next thing
we know, people will be daisy chaining dryer elements to increase their
sockchain computing power, pricing the rest of us out of the market.  Wet
sock wearing will be on the rise.

Re: Docker

[Mike Bonner via use-livecode]

Mostly i'm looking to learn how things work, but the end goal is to a) have
a front lc based controller (httpd) that can hand off jobs to a pool of
docker "processors," and getting a handle on how to dynamically spin up
more instances based on demand.  (kubernetes?)  I don't know enough yet to
use the right words.  I could do all this exploration without lc, but it is
so much easier to put together whatever processors I want in lc, so that I
can spend most of my (limited) energy focusing on the docker side.

One thing I may try to set up..  I have an old HP z800, with 24 possible
threads, and I also have most of the (english) files from project
gutenberg. I'd like to process and index all those files into a searchable
database, using 24 docker images at once, each assigned to a core.  IE take
advantage of my knowledge of LC, while at the same time, bypassing its
single thread limitations.

I have a similar goal with a bunch of climate data from
https://www.ncdc.noaa.gov/cdo-web/datatools that I want to use to calculate
worldwide temperature trends.  (Both of these things, as well as all the
docker stuff are over my head right now, but maybe I can close that gap.)

Hoping someone can help me shortcut this..
If I start with an alpine image, what things do I need to add so that LC
executables will run?  (using the -ui flag)
Or would I be better off starting with another base?   I'm looking to end

Re: What are possible reasons for memory consumption ...

[Mike Bonner via use-livecode]

Or alternatively, check the pendingmessages and only send if there is not
already a message for the handler in question in queue.

I've had situations (in my case, bad coding) where I thought I was starting
a looping handler once ,but had left a call to that handler elsewhere
accidentally during the re-think process.  In those cases, even if it is a
seldom run handler that has the mistake, every time it is called, a new
instance of the loop starts.  In my case, (since I have trouble tracking
details as complexity grows beyond a certain point.. Small scale I'm great,
large scale, not so much) I've just made it a habit to always do the
pendingmessage check before sending again.  (I have lots of little rules
like this to help me manage my own personal limitations in a consistent
way.. Like always including a way to exit a tight repeat loop during
development at least, to avoid issues with runaways.)

Hmm. I tend to run on about things lately don't I?  Feel free to ignore any
extraneous blab.

Re: odbc "information type out of range"

[Mike Bonner via use-livecode]

I have no way to test it, but if you change your insert to..
insert into employee (empno) values (double(-1))

Does it make a difference?

Re: Capture Keystrokes & MouseMovements without being in focus?

[Mike Bonner via use-livecode]

Cool, yep.  For that purpose it should work great.

Its interesting when using this method for a game.. One can be typing code
into the script editor, and the game does interesting things because its
still looping.  Not that I have ever inadvertently done such a thing...

Re: Capture Keystrokes & MouseMovements without being in focus?

[Mike Bonner via use-livecode]

The only way I know of is to start a relatively fast send loop and check
the keysdown().  For some things it works fine but for most other things
its not a good answer since you can see if a key is down, but not how long
its down, or tell if it has been pressed, then pressed again before the
next loop cycle. All you can do is see that the key IS down.

If you wanted to say.. Have a loop processing something in the background,
you could have it check the keysdown for  and
if they're present, use revspeak to say how far along the process is.  If
you want to do a real, accurate logging of keys though, I'd say its a no go.

Re: Script Only Stack Behaviors and Nesting

[Mike Bonner via use-livecode]

Curious if this would be useful.  It occurred to me that one could use
getters and setters in the behavior if one wanted a "central" location for
data for objects using that behavior.

Not as easy as just using an actual property set, but might end up being
faster?

To test I put the following into a button to use as a behavior..
local sOhBehaveLocalA

on mouseup
   -- sets a value in the local of the behavior object
   -- based on the long id of the object using the behavior
   set the setter[(the long id of me)] of (the behavior of me) to
random(4000)

   -- grabs the whole array from the behavior object
   put the getter of (the behavior of me) into tArray

   -- shows the value assigned to the array entry for the
   -- object using the behavior keyed by long id
   put tArray[the long id of me] & cr

   --cycles through all keys in the array returned by getter
   -- and shows values for all objects tracked by the getter/setter in the
behavior object
   put the keys of tArray into tKeys
   repeat for each line tLine in tKeys
  put tLine & ":" & tArray[tLine] & cr after msg
   end repeat

end mouseup

Then assigned the behavior to several buttons and it works well enough.
LIke I said, i'm not sure there is actually a point to this since there are
so many other ways the same objective could be reached, but thought I'd
toss it out there.  (sorry for the ugly code and silly example) I think I
read somewhere that setting a variable is faster than setting a property,
but.. /shrug

Re: Sort IP List

[Mike Bonner via use-livecode]

Now that is weird because the sort is definitely working for me.OH
wait, you don't set the numberformat in your function.  Do you set it
elsewhere, and if so, does it stick when the function is called?  The sort
is definitely, no question, working for me.

I generate a list of IPs then in the msg box do this..

set the numberformat to "000"
set the itemdel to "."
put the millisec into tstart
sort lines of tList ascending numeric by (item 1 of each +0) & (item 2 of
each + 0) & (item 3 of each + 0) & (item 4 of each + 0)
put the millisec - tstart
put cr & tList after msg -- the list is sorted.

Not sure why it isn't working for you, but on the off chance its a version
difference, i'm on 9.0, community +, stable.

Re: Sort IP List

[Mike Bonner via use-livecode]

Thx for the clue, I see what you mean.

I had tried to get something similar to your value(item 1 of each +0)
method to work and something wasn't clicking, but after seeing yours, I
think I have it working.

sort lines of tList ascending numeric by (item 1 of each +0) & (item 2 of
each + 0) & (item 3 of each + 0) & (item 4 of each + 0)

The above seems to work fine (and I avoided using value() to avoid an
unnecessary function call), you just have to remember to set the
itemdelimiter to "." otherwise you get the error.  This may be faster
because there aren't a bunch of function calls like my first idea, though
I'm not sure how overhead compares since the numbers must still be
evaluated.

Just did some testing and it seems to be way way faster.  100k lines sort
in 3/4 of a second.

Actually, when using the multiple key sort, dont reverse the order since it

Re: Sort IP List

[Mike Bonner via use-livecode]

Ok, now i'm curious about something.. I know its possible to designate
multiple keys to a single sort using the form..
sort lines of plist  by item 1 of each &  item 2 of each & item 3 of
each & item
4 of each
which works fine.
But changing it to..
sort lines of plist  ascending numeric by item 1 of each &  item 2 of each &
 item 3 of each & item 4 of each  -- reverse this for your desired sort
doesn't sort numerically (even if each key is forced to numeric with a + 0)

BTW, I had to go back to comments in an older version of LC to remember how
to do the multiple-key sorts.

Since it ignores the "numeric" part, if one limits ips to all 3 digit
numbers, the sort works as expected despite sorting as  alpha.

So my question is this.. Would it be a reasonable feature request to adjust
sort so that its multiple key format respects the numeric sort type?

Re: Sort IP List

[Mike Bonner via use-livecode]

## was writing this when your response showed up..
Just did some tests.  For reasonable size lists of IP numbers, your method
is clearly faster. As lines increase the disparity shrinks (due to 4
processings of the same lines rather than 1) until around 35000 lines at
which point positions reverse and the disparity grows in favor of the
function(each) method.

After just a bit more testing, the fastest method (for anything over 2
lines) is to run through the whole list first converting it to numeric and
then do a single simple sort, but that leaves you with a straight list of
numbers that would then have to be re-divided into triads, so the post
processing needed kills the whole idea.

As for your response,
Yes  the function is called by sort for each line and returns the numbers
to use to give that line its sort value.  It isn't as fast as I had hoped
most likely because it has to call a function for each line in the list.
With the first method I posted, on my machine, the crossover point is right
around 35000 lines (at least on my system, at 35000 lines it takes 475
millisec to 612 millisec vs the 4xsort)   At 200,000 lines the disparity
grows to over 3 seconds difference, but i'm unsure what max length list
might be reasonably expected.  The 4 sort method is by far the simplest to
code and is plenty fast for list under 10.
The nicest part of your method is that if processing a huge list, its easy
to give visual feedback between each sort if need be.  But again, all this
is likely moot unless the ip list is huge.

Re: Sort IP List

[Mike Bonner via use-livecode]

I don't know what speed differences there might be, but another option is
something like this..

function ipfunc pIp
   set the itemdel to "."
   set the numberformat to "###" -- force length of each chunk to 3

-- append the numbers together sans "." with padded 0's using numberformat
   repeat for each item tItem in pIp
 put tItem +0 after tIp -- do the add to force the numberformat to
work
   end repeat
   return tIp
end ipfunc

And then use it like so..
sort lines of myIpList ascending numeric by ipfunc(each)

Re: Grabbing a widget

[Mike Bonner via use-livecode]

I haven't found a way to make it stop sticking either.  And I agree with
the QCC entry that basic mouse event type messages including the ability to
use "grab" or whatever should be glommed on to all widgets in some way.
 Admittedly, the grab issue can likely be worked around (mousedown itself
works, you can have mousedown PUT a random number from the widgets script,
its the grab in this case that doesn't work..) so one could use the old
mouse is down set a flag mousemove method to change its location, but in
many cases grab/dragdrop is preferable.

Re: Translation Service Deepl.com

[Mike Bonner via use-livecode]

Same method as yandex from a recent thread, built your query string some
way and send it to the server.

something like..
put urlencode("Text to translate") into tText
put  "https://api.deepl.com/v1/translate?text=; & tText &
"target_lang=EN_key=YourAuthKeyHere" into tUrl
get URL tUrl
put it

You could also use POST rather than get using the same base url (
https://api.deepl.com/v1/translate) according to the documentation.

merge()

[Mike Bonner via use-livecode]

I just had a thought while pondering some code from another thread.  I have
done things like put merge("This is a random number: [[random(tNum)]]")

Since merge can do what do can, is there a way this method could be taken
advantage of using an injection type of attack?   I'm thinking the answer
is no, (and I haven't managed to find a way to inject yet,) other than
allowing a user to build the whole merge string themselves (which would be
a "bad thing to do" (c))

Am I wrong?  Is it safe as long as I don't do anything careless?

Re: calling an api from a stack?

[Mike Bonner via use-livecode]

If you mean using merge inside the function, I guess one could do the merge
beforehand and pass it in as a parameter, or alternatively do the merge in
the function and return the generated url string as part of the returned
value.  IE change it like so..
function translate pText,pLang
   put merge(kGetTransUrl) into tUrl
   get url tUrl
   return "URLString: " & tUrl & cr & it
end translate

Then just dump the first line if things are working right.  Hmm. Actually,
pre-merging is nice because it would allow the use of "load" with callbacks
for multiple url calls. Use the callback to process, part of which lets you
see the URL associated with the callback.  Sounds like a better option than
using a function call for sure.

Re: Regex (matchChunk) help...

[Mike Bonner via use-livecode]

Glad it worked.   If it turns out there is a reason not to use trueword and
a for each loop, the same basic algorithm can be used with offset() but it
would be a bit more convoluted.
Basically, find the first offset for the beginning string, then use that to
skip chars to look for both the beginning string and ending string.  If
both are found, replace the initial offset for beginning with the new
offset, use that info for the next chars to skip, and do it again.

There would be several more things to watch for, like having a current
beginning offset, doing your check, and making sure you still have a match
even if there isn't another beginning offset, and only an end. (and various
other combinations i'm sure) but it shouldn't be too bad to figure out if
the other solution is ruled out for some reason.

Re: Regex (matchChunk) help...

 Slightly cleaned up, and adjusted to empty tPair after a match.  (on the
off chance there is a second ending without a matching new beginning word)

Re: calling an api from a stack?

[Mike Bonner via use-livecode]

jsontoarray returns an array, you'll have to dig through the array to find
where pieces of information reside, but it pretty straightforward after you
poke around.

For example.. If you instead do this..
put jsontoarray(tResult) into tArray

you have an array variable named tArray.
If you-- put the keys of tArray you'll see the first level of keys.
One of the keys is named "text" and it has a numeric subkey named 1
So if you-- put tArray["text"][1] into field 1
The translation will be placed into the field.

YOu can use the "put the keys"  syntax to find subkeys too, so if you-- put
the keys of tArray["text"]  you get back the single subkey 1. If you were
to-- put the keys of tArray["text"][1] you would get nothing back because
there are no subkeys.  Instead, a value has been placed into key
["text"][1] which is your translated text.  Its pretty easy to poke around
an array this way and figure things out, especially since the array for
this is pretty simple. (also look at "elements" in the dictionary)

Try this..

   put 1 into tCounter -- tracks current word
   repeat for each trueword tWord in tText
  switch tWord

put tCounter into tPair
break
 case tEndword
if tPair is not empty then
   put tPair & comma & tCounter & cr after tPairs
end if
break
  end switch
  add 1 to tcounter
   end repeat
   delete the last char of tPairs
   repeat for each line tLine in tPairs

Re: Regex (matchChunk) help...

[Mike Bonner via use-livecode]

If I understand correctly.. If you find the beginning string occurrence,
and then find another beginning string, you want to ignore the first, and
only take strings where beginning and end have no intermediate beginnings?
Like this I mean..

beginning blah blah blah blah blah *beginning blah blah blah blah ending*

Where you would only want the bold part to match?

If so, it might be easiest to do a repeat for each trueword loop.

put 1 into tCounter
repeat for each trueword tword in tText
/*pseudocode
check the word. If its the beginning word, keep track of it using tCounter
so you know what word it was
If you're tracking a beginning and you hit a beginning again, track that
one instead.
If its the ending word, and you have a beginning word being tracked, place
the pair of word numbers into a list of found strings and reset the begin
tracker to empty
if its neither, do nothing
increment the counter
next loop
*/
end repeat

Of course if I've misunderstood what you need, kindly ignore this.

Re: scancodes

[Mike Bonner via use-livecode]

Don't think of a key press and key release as if they should be 2 different
can codes, instead think of them as as being state changes.  Like a light.
Send power to the lightbulb, the light is on. Remove power from the bulb,
the light is off.  The bulb is still the same bulb.   Same with the
keyboard and keycodes.. The light is on! (key pressed)  The light is off!
(key released)  The identifier for the key (the scancode) remains the
same.  Or from a livecode perspective.. Click and hold a button and on
mousedown, report the target.  on mouseup, the same target is reported due
to a state change.  Click begun (mousedown)  click completed (mouseup).  So
no, the scancodes shouldn't be different.  (If you play with an arduino,
the same applies there.  Checking and changing pin states, setting a
voltage high, or low, but the pin assignment remains the same, only its
state changes from high to low, IE on to off)

Re: Area of regular polygon triangles

[Mike Bonner via use-livecode]

If you need to use the box method, and the control rect isn't perfect,  it
might be easier to create the rect on your own.  Go through the points and
find the topmost, left most, rightmost, bottom most coordinates and that
gives you your box.  Alternatively, if you just want the area and don't
care how you get it the equation is pretty straightforward.

area
=
A
x
(
B
y
−
C
y
)
+
B
x
(
C
y
−
A
y
)
+
C
x
(
A
y
−
B
y
)
2
where Ax and Ay are the x and y coordinates of the point A etc..   I have a
stack that does this while dragging points around, it works well enough.

if I understand correctly, and just off the top of my head, using "limit"

The sql pseudo code would be something like:  select * from yourtable order

Re: Graphing Solution...

Actually, change 2 lines and I think it'll work better:
Line 932, change to:  updateGridRect(rectangle [gridLeft(), tPadding +
tNeededTop, mWidth - tPadding - mMaxYLabelWidth, gridBottom()])

Line 1061 change to: fill text tString at left of rectangle [tYRight +
gridPadding(),tY-20,tYRight + mMaxYLabelWidth + gridPadding(),tY+20] on
this canvas

I floundered around cluelessly with it for a bit, randomly changing a few
things till I got something that seems to work.  I'm sure there are things
I still misunderstand about this, and that I've added code that probably
doesn't need to be there.  Also not sure if there will be issues with
larger labels etc, but if you're interested, the modified stuff can be

If you do a diff of the stock lcb and the lcb in the zip archive, you can
see all my (unremarked) floundering differences.  As it sits though, the
default data comes up and displays fine.  Just checked with larger values,
some of the numbers I poked in there should probably be increased a little,
though i'm sure theres a better way to calculate such things.

Re: Was: URGENT: MergGoogle no longer works on iOS: CLIENTS VERY UNHAPPY

[Mike Bonner via use-livecode]

 Curry-  don't know if such a thing would help your situation, but i'm
attaching a photo of my lift.  Its simply a relatively small i-beam solidly
anchored, a trolly to match, a 2000lb hoist (overkill) and a very simple,
self designed sling hooked to a home made spreader bar.  Lower it, sling in
front, spreader bar in back under my arms, push the button, and voila' I'm
levitating, at which point its easy to peter pan back and forth across the
room.  (Though I look like i'm ready to be processed at a butcher shop)
Compared to the cost of a "professional" ceiling lift, the cost was around
8K less before install costs (because you apparently can't just buy parts
here and DIY.)  Photo isn't great but here it is if LC will let it post.
Ignore the mess.

No go on attaching the photo, so heres the dropbox.

Re: Was: URGENT: MergGoogle no longer works on iOS: CLIENTS VERY UNHAPPY

[Mike Bonner via use-livecode]

 Hey Sean,

While its true that the full details of what was going on weren't
available, there were 2 things that stood out to me from your previous
writings.  Large amounts of distress, and a monetary connection to the
distress.  I can't help with the distress directly, but it just makes sense
to me that sending a bit of financial care your way might help smooth out
this rough patch.  I myself have had to face down my pride issues and
accept help in the past.. well actually all the time due to my health
stuff.  If not for the care of people around me, my position would be much
much worse. The most recent hit to my pride was the loss of ability to self
transfer into my walk in tub, (a thing I learned the hard way.)  People who
care about me got together, designed, and installed a ceiling lift that
works amazingly well.  And I can do an engine swap in my bathroom.  (Its a
mite over-engineered.)  Just one example of people being awesome.

One thing I've taken to heart is a simple saying.  "Accepting the gift,
honors the giver."

If it will help, I'd be honored to assist a bit more, but now that we've
heard from you, I would prefer to leave that to your discretion.  If you
wish, you are welcome to send a direct email to me.

Take care of yourself,

Mike

Re: on-rev choosing engine

[Mike Bonner via use-livecode]

Thanks, I'll try this and see what I can figure out.  It seems though that
the server engines aren't there. (not found) type errors.  Using the info
from that lesson, there should be an engine at
/cgi-bin/livecode-server-4.6.3 for example.  (or any version based on the
same format, with the exception of the default (7.0.1) which is at
/cgi-bin/livecode-server according to the lesson, and the irev version is
in a different place too.  )

Then it goes on to give the example as in 4.6.3 which matches the
description of how things are named/placed.  But its not there.  When
running standard, no .htaccess, the livecode-server is located at

/usr/local/cpanel/cgi-sys/livecodeserver-7.1.0/livecode-server

So it appears that the lesson is wrong here too, and that the handler for
.lc files would point to /cgi-bin/livecodeserver-7.1.0/livecode-server
rather than as described.

I thought maybe things were the same, so tried with
/cgi-bin/livecodeserver-4.6.3/livecode-server but thats a no.  I also did a
shell call, when doing shell("ls
/usr/local/cpanel/cgi-sys/livecodeserver-7.1.0/  the files are there as
expected.   When doing the same for livecodeserver-6.4.3 the directory
doesn't exist. All this would be made easier if I had permission to ls
/usr/local/cpanel/cgi-sys/ to look at whats there, but thats not possible.

I'm guessing the scriptalias points to /usr/local/cpanel/cgi-sys/ so if
anyone has a clue how things are actually named for LC server versions
underneath that, that actually work, I'd appreciate the info. Otherwise,
I'll msg support and ask there.

on-rev choosing engine

[Mike Bonner via use-livecode]

Has anyone had luck using an .htaccess to change the engine used with
onrev?  I'm hoping to override 7.0.1 (the default version it seems) with a
more recent version, but the information here:
http://lessons.livecode.com/m/4070/l/41105-how-do-i-choose-which-livecode-server-engine-to-use-with-on-rev
doesn't seem to work.  I even tried the older version used in the example
(4.6.3) and its not found.  If it works for others, i'm thinking there is
something munged in my account specifically.  If you DO have it working,
i'd appreciate an example so that I can duplicate it to test.

Re: PDF

[Mike Bonner via use-livecode]

I ended up using pdftotext, it worked like a charm. (Though I had to look
up how to send it a file list using find..  Too long away from the shell.)
I now have a little app that can do a word search for matching files and
show either the extracted text, or the original pdf using the browser
widget.

As far as being on the "make pdfs go away" bandwagon, yes I am.
Unfortunately, they're still used all over the place.  Insurance companies
autogenerate a huge amount of pdf reports, some of them built live through
horribly slow clunky awful (insert a bunch of other words here to describe
how NOT enjoyable it is to use their websites) that then eventually (after
going through huge amounts of different screens, get to the end result)
hand you a pdf./endInsuranceWebsiteVent

Reminds me of when I worked as phone support for a "large computer
manufacturer".. When there was a workflow issue, and slow call times due to
waiting on page loads for vantive.. The answer usually ended up being..
"Hey, its already slow so lets add 3 more required page loads that can take
forever to complete especially on busy days, thereby slowing things down
even more..."  /endPhoneSupportVent

Ty Paul.  Unfortunately, a business license is way outside my level of

PDF

[Mike Bonner via use-livecode]

I haven't needed to do this before, but is there a (relatively) easy way to
extract the text from a bunch of pdf files?  I'm hoping I can build some
indexes for the boatload of files I want to go through.  (THough, I guess I
could bipass LC and just grep my heart out)

Any suggestions?

Re: Active window and mouse location

[Mike Bonner via use-livecode]

Oh, one other option for windows would be vbscript.   Unfortunately, I
don't think you can "do myScript as vbscript" because (according to the
dictionary) the required objects aren't available to livecode using that
method.  You can however, create a .vbs file with a script that should be
able to bring your app to the front.  Put the file somewhere accessible,
and use launch document to run it.  There are threads on this in the forum,
I'll re-locate them if you are interested in the idea.

Re: Active window and mouse location

[Mike Bonner via use-livecode]

Hmm Just a curiosity question to further the experiment if you don't
mind..   I had been thinking you could use the "click" command to bring
things to front, but if its not in front you can't do that.  So out of
curiosity.. If you set it to a system window so that its in front of
everything, and then use the click command (click at x,y) then
un-systemwindow it, does it retain focus?  I'd test here, but for some
reason it behaves differently for me.  (It sounds like your autohotkey
answer is still the better option.)

Hmm. Not sure whats up then.  doing the systemwindow trick pops things to
the front for me from behind a browser of whatever happens to be in front,
so no clue why it won't work for you.  (unless the window that it is behind
is a system window itself)

Re: How to turn off editor formatting

[Mike Bonner via use-livecode]

If there isn't an option to turn off autocomplete, my guess is you're using
a version that didn't give you the choice.  I'm using the most recent 9.
Turned off brackets and bracket hiliting, turned off the live error
checking and auto complete.   All I have on is control structure complete,
and auto formatting.  Thankfully this helps with the windows 10 slow down
issues enough to make things bearable.

Re: imagedata and alpha byte

[Mike Bonner via use-livecode]

Already assuming that you know which pixel you wish to modify, (like if you
want to modify pixel 25 in pixel row 3, that would be pixel 75.. I
think..)  you would need to do something like the following..

--first, put the current alphadata into a variable.
put the alphadata of img "myImg" into tAlpha

-- then modify the alphadata for the pixel in question
put numtochar(0) into char 75  of tAlpha -- 0 is transparent, 255 is
completely opaque
-- change all necessary pixels here then
-- set the image to the new alphadata
set the alphadata of img "myImg" to tAlpha

Re: Active window and mouse location

[Mike Bonner via use-livecode]

While the solution is not perfect, you can have your script
set the systemwindow of stack "stackname" to true
wait 1 tick
set the systemwindow of stack "stackname" to false

(Saw this on the forums at one time or another, think the thanks go to Lagi)

The only negative of this method is the flicker as it goes system, then
back again.

If you go to "sample stacks" from the livecode bar, on the upper right you
can either log in or sign up. Sign up to create an account, at which point
you should be good to go.

Re: Down a leafy lane or up queer street?

[Mike Bonner via use-livecode]

Did you declare it as a global on the card also?  You have to declare it
for every context that it will be used.  Stack, card, if you use it in a
button script, wherever.

If you've declared it in a card script, and set its value, but then use it
WITHOUT declaration all you get back is the text of the name (IE route66)

The reason you can see the value when checking it from the message box, is
that it is executing the commands as if they were in the context of the
stack script.

To test what I mean, create a script in a button with the following:

on mouseup

put "undeclared variable:" && tUndeclared -- shows tUndeclared in the
message box

local tDeclared

put cr & "Declared but un-set variable:" && tDeclared after msg -- no value
shown, tDeclared exists but is empty

put "value set" into tDeclared

put cr & "Declared and value set to: " & tDeclared after msg -- tdeclared
exists and now has a value

end mouseup

 I have a stack containing a series of images that are 'empty' images
 with their
 sources set to an external folder.

 Now in my stackScript I have this:

 |global route66 on preOpenStack put specialFolderPath("resources") &
 "/Desktop/Obfuscated/May 2018/assets/img/" into route66 go to card
 "TITLE" end preOpenStack|

 and in my cardScript I have this:

 |on preOpenCard set the lockScreen to true  set the filename of
 img "p1" to empty --- set the filename of img "p1" to (route66 &
 "c1.png") set the blendlevel of img "p1" to 0  wait 3 ticks set
 the lockScreen to false end preOpenCard so, WHY cannot I see the target
 image, merely a horrible grey square? Richmond. |

Re: Get only Pathname of a dragdropped Object

[Mike Bonner via use-livecode]

when you set the dragaction, it doesn't actually DO  the action.. All it
really does is a) set the prompt to the action you intend to do, and b)
send that info back to the source of the dragdrop. (not positive about that
second part)

So, if you have a button as the destination for your drag drop, in order to
allow the drop, you need a dragenter handler

on dragenter
   set the dragaction to copy
end dragenter

Then you need a dragdrop for the button also.

on dragdrop
 if the dragdata["files"] is not empty then
 -- this is where you do your processing
 -- dragdata["files"] contains a line delimited list
 -- of the files and folders dropped. (but not the files/folders
themselves)
 -- see a complete example below
 end if
end dragdrop



##
--Create a stack with a button and a field. Add the following script to the
button.

on dragenter
   set the dragaction to copy
end dragenter

on dragdrop
   if the dragdata["files"] is not empty then -- make sure there is
actually a file/folder dragdrop
  put the dragdata["files"] into tData -- put the file/folder list into
a temporary variable

-- Go through the list and determine whether each line
-- of the data is a folder or if it is a file
  repeat for each line tLine in tData
 if there is a folder tLine then put "Folder: " & tLine & cr after
tList
 if there is a file tLine then put "File: " & tLine & cr after tList
  end repeat
  delete the last char of tList
  sort lines of tList

-- put the list of dropped files and folders into the field
  put tList into field 1
  pass dragdrop
   end if
end dragdrop

Re: Title Case

[Mike Bonner via use-livecode]

Not sure what you mean?
Also, definitely use one of the Andy versions to "case" your titles.  Much
more comprehensive solution.  The only edge case I can see would be
something like a title with a McGary type name, pretty much impossible to
account for without looking up every word in a names DB.

Re: Title Case

[Mike Bonner via use-livecode]

Something like this might work..

put "a create a sentence title" into tTitle
repeat with i = 1 to the number of truewords in tTitle
   put toupper(char 1 of trueword i of tTitle) into char 1 of trueword i of
tTitle
end repeat
put tTitle -- the adjusted case sentence

If you have words that you would rather not uppercase of course, you'll
have to check for those. (like of, the...) and whether or not the word is
the first.

Can you share the code to the page you're actually posting to?  Its
sounding like its not actually returning any output, causing a 500 internal
error.  Just to let you test, I set up a quick and dirty page at
http://guidezone.info/test.lc
The code in the page is as follows.

"
   end repeat
else
   put "Error: No data posted" -- gotta put somethingto avoid a 500 error
end if
?>

To test it, I used the following in a button.
put "Accept: text/plain" & CR after tHeaders
put "Content-Type: application/x-www-form-urlencoded" & CR after tHeaders
set the httpHeaders to tHeaders

put liburlformdata("name","Chi","gender","male","color","black") into
tPostData

put tPostData & cr --so that I can see the generated post string

post tPostData to "http://guidezone.info/test.lc;

put it && the result after msg


This works for me, though as I said, I don't have tsnet.  You're welcome to
do test runs against my url if you like. If it works for me as written, and
not for you, i'd be pointing my finger at tsnet.

Re: name resolution stinker

[Mike Bonner via use-livecode]

Not sure if this will be userful, but would placing the following script in
your stack (or frontscript I guess) work easier?

command amIHere pName
try
   dispatch "imHere" to group pName of the current card
catch tError
   return false
end try
end amIHere

command imHere
   return true
end imHere

Might be cheating using try this way, but I think it should work pretty
well.

If the dispatch fails due to object (or in this case, background) not found
error, you get false, if the dispatch is handled you get true.

Re: Text to Speech

[Mike Bonner via use-livecode]

Check the result and see if there is an error message.  What OS/Platform?
I use revspeak to talk to an amazon echo since it speaks more clearly than
I do. (Had it set up for a while so that I could have it talk to my echo
while I was in another room using a rev http stack.)  I'm on windows, but
think that last time I tried it on mac, it worked fine there as well.

Re: Standalone Settings Frustration

[Mike Bonner via use-livecode]

Just a guess, but if it happens again, I'd look at "the filename of stack
 and if its not what you want, change it. ( I can think of
another few possible ways that it might be forced to change, but this would
probably be the easiest)

Re: memory databases fail in Windows

Yes please!

###I hear ya'.  I find myself tempted way more than I have time for to
write an xquery-like library for working with arrays.  We could sure use
one.###
