Since order must be maintained, it’s probably faster not to split and sort, and 
faster not to scan the list repeatedly using lineOffset or contains.
You could do it like this:

command removeDuplicates pDelimitedList, pDelimiter
   local tArray, tList
   set the lineDelimiter to pDelimiter
   repeat for each line tLine in pDelimitedList
  if not tArray[tLine] then -- i.e., if this line hasn't appeared already, 
then ...
 put true into tArray[tLine]
 put tLine & pDelimiter after tList
  end if
   end repeat
   delete last char of tList
   return tList for value
end removeDuplicates

Re: Speaking of Filter and Match...

[Bob Sneidar via use-livecode]

The UNIQUE clause is the UNIQUE combination of ALL the columns put together. If 
I used: 

SELECT city,state UNIQUE FROM zip codes where state = 'CA' 

I would get every unique city/state combination in CA, whereas if I used: 

SELECT state UNIQUE from zip codes where state = 'CA'

I would get the first record matching 'CA', that is one record. 

There is a way to get the city and state for the one record (why anyone would 
want to I don't know) by creating a join to the same table and using the UNIQUE 
clause in the join. I am not that good at join syntax, so I won't attempt it 
here and embarrass myself. :-)

BTW you can get the last matching record by doing an ascending sort and using 
LIMIT 1, but I think MS SQL suffers from not having a limit clause. Not sure 
why. Instead you use the TOP clause.

Re: Browser Widget and Images

[Rick Harrison via use-livecode]

Thanks!

I had forgotten about "import as control" and about
set the imagedata of image “my image”.

set the imagedata doesn’t fit to the image’s object size though.
I would probably have to resize the image beforehand.

I also came across:

put URL "binfile:///ExportedImageFile.png" into image  “my image”

The above does fit the image size nicely and I can paint on it etc.

Thanks for all of your help!

Rick

 Making the list into an array is the easiest way but as mentioned, it will 
 destroy the original order. If the order is important then you can restore 
 it with a custom sort function. Here's my test handlers:
 
 
 on mouseUp
 put fld 1 into tData -- we keep this as a reference to the original order
 put tData into tTrimmedData -- this one will change
 split tTrimmedData by cr as set -- removes duplicates
 put keys(tTrimmedData) into tTrimmedData -- convert to a text list
 sort tTrimmedData numeric by origOrder(each,tData)
 put tTrimmedData into fld 1
 end mouseUp
 
 function origOrder pWord, @pData
 set wholematches to true -- may not matter, depends on the data
 return lineoffset(pWord, pData)
 end origOrder
 
 Field 1 contains lines in random order with duplicates.

Re: Speed up a slow loop

[J. Landman Gay via use-livecode]

One last thing. Scott Morrow was good enough to build for iOS and send a screenshot. I was very 
pleased to see it went cross-platform without any significant problems (thank you LC!) but the 
custom font was missing, which makes sense since I didn't include any external resources. That 
reminded me that it probably didn't have an icon either.


I've updated the zip file download to include the resources needed; icons for all platforms 
(but the Windows one is very old) and a copy of the font. Update your standalone settings to 
accomodate the paths you need.




Thanks guys.

Re: revOpenDatabase over SSH tunnel?

[Ben Rubinstein via use-livecode]

I can't speak for most of the world, but in the past where we've directly 
connected to MySQL over the internet that's always been limited by IP (which 
as you doubtless know is built-in to the permissions system).


The difference for me in this case is that instead of talking to a dedicated 
server, we're accessing a shared managed database service - hence these 
additional measures make sense.

Re: Speaking of Filter and Match...

[Bob Sneidar via use-livecode]

They depend on the fact that arrays cannot have duplicate keys. Dumping the 
data into an SQL database and querying using the UNIQUE statement would do it 
too. 

SELECT * UNIQUE from ...

LC 10 DP2, does it already support the current multimedia architecture on Windows?

[Klaus major-k via use-livecode]

Hi all,

the subject says it all.
Means do we still need to install e.g. the LIBAV codecs to 
display MP4 video files?

Or is this newer feature not yet implemented in DP2?

Thanks for any hints.


Best

Klaus

Re: Windows EXE with browser about 160 MB?

[matthias rebbe via use-livecode]

I would say, this is because Microsoft did not embed CEF into Windows. 

So if you customers are asking why, tell them "because they are using Windows" 
and if they want to use a smaller download file they should use macOS. ;) 

I for myself would not have a problem with a download size of 170MB for a 
program i want to use. Compared to Adobe, MS Office and other programs, 170MB 
are not worth moaning about 

But that's my opinion.

what Jim said! :-)

Thisw way the image becomes part of the stack as if "imported as control" 
and you can paint on it or whatever, which is not possible with referenced 
images, be they local or online.
