Check connection and timeout

[Ludovic THEBAULT via use-livecode]

Hello,

I use this code to check is there is an internet connection :

 tsNETSETTIMEOUTS 60,0,2000,6,5,1000

 put tsNetHeadSync("https://google.com/";, tHeaders, tResult, tBytes) into 
tRecvHeaders
   
   if tResult begins with "tsneterr:" then
  return false 
   else
  return true 
   end if
 

But the setting for the timeout of tsNETSETTIMEOUTS is not active, I always 
have a 30 seconds timeout.

Is there an other settings ?

Thanks.

Re: Convert date

[Neville Smythe via use-livecode]

Jacque: Nice! Particularly as a demonstration of the variety of ways to achieve 
an objective in LC and different coding styles. I’ll add the snippets to my own 
version.

The ISO date (aka sql date) format is my favourite because it avoids the 
ambiguity of the English/American ordering of day, month and mostly because it 
works for sorting. I could wish it were universally adopted.

Thanks to Richmond, Mark, and Jacque for your responses.

So, I actually need to note the position of the selected (i.e. char x to 
y) rather than the selected text itself.


Indeed, if you have text highlighted in a lock, scrolling text field 
(autohilite on) and click a button, the highlight does not go away. 
However, if you click on another field it does. I need a solution where 
the highlight appears to remain in the primary "Content" field no matter 
what else the user clicks on in terms of other UI actions.


So, it still seems the "best" way to do this is using the on 
selectioChanged message and getting the selectedChunk and if not empty 
and word 2 is not > word 4 (insertion point), then save word 2 as the 
start and word 4 as the end and change the background color of the 
selected range to the highlight color, clearing another of background color


This makes it appear that the selection remains, updates it when the use 
makes a new selection, but sacrifices any other use of background color 
for the text in the field (which I can live with)


Thanks all,

  convert pDateTime to dateitems

Actually, I've been trying different button and field settings and no matter what I do, the

not sure what changed because it didn't used to be that way.

Re: Crazy question: is it possible/reasonable to use Python in LC?

there are no crazy questions
there is, however, bat-guano-crazy geoff canyon

analyzer, etc., and all the other pre-compiler stuff that you would
have to write for any language. i'm not aware of something like a DLL
for python.
even better, while we're wondering, wouldn't it be great if we could
implement any interpreted grammar? i'd love it, because our erp
software is written in a a BASIC-COBOL-Fortran thing. I could dump all
the 1970's-era tools for managing forms and databases and replace them
with something nicer.

Crazy question: is it possible/reasonable to use Python in LC?

[Geoff Canyon via use-livecode]

I've been playing with Python, and it has a lot of nice qualities, but a
built-in GUI isn't one of them (no apologies to tkinter).

So it would be interesting/nice to be able to open LC, add a button to a
stack, and put some python into the script of that button and have it just
work, with access to the rest of the LC stack/controls as usual.

Obviously that's not possible, but how close can we come? I assume it would
be possible to write a shell command to trigger a python script, but that
seems complex and sub-optimal, especially when thinking about having to
bundle together all the bits and bobs from the LC UI to pass as arguments
to the Python script instead of having it able to just reference what it
needs on the fly.

Anyway, wondering if anyone else has thought about this.

Re: Field highlited

[Mark Smith via use-livecode]

Hi Paul, try “the selectedText".

Create a scrolling text field, call it fld1, and put a large amount of text in 
it.
Create 2 buttons: one with “on mouse down, answer “Hello World” and the other 
with “on mouse down, answer the selectedText of field “fld1”

Now highlight an area of text in fld1. Click either button, the highlight in 
the text does not go away. The first button responds with “Hello World” and the 
second responds with the highlighted text in fld1.

I am using LC 10 if that makes a difference, although just tested in 9.6.8 and 
it worked there as well.

Re: Field highlited

I just did this:

on mouseLeave
   put the selectedText of fld "f1" into fld "f2"
end mouseLeave

you can then do whatever you want with your button on the basis of the 
contents of fld "f2"


Best, Richmond.

There would need to be a script that could simply returns the content of a line of a

requires. You could have multiple lines selected, and other variations as needed.

I think that Bob S. is correct. The change in focus is sort of built into the 
engine, and a field cannot “remember” such a thing.

A fun kludge would be to create one or more overlays, however you like those to 
look, and apply them to the field of interest. These overlays can be managed in 
terms of their rects, depending on the formatted properties of the hilted line 
or lines. They can be shown and hidden as well.

I am struggling not to do this just for fun. So you do it, because I bet that

Re: Field highlited

[Paul Dupuis via use-livecode]

Thank your Bob, Craig, and William for the responses. It appears the way 
I have done it in the past is the "best" option. I was hoping there was 
some clever trick I don't know, but it is what it is. I'll do what I 
have done before. Thanks again.

Re: Field highlited

[William Prothero via use-livecode]

Folks,
A possible strategy is to change the color of a line in a field, when it is 
selected. There would need to be a script that could simply returns the content 
of a line of a specified color, changes the color to "unselected", or whatever 
your need requires. You could have multiple lines selected, and other 
variations as needed.

Just thinking.
Bill

Re: Field highlited

[Craig Newman via use-livecode]

Paul.

I think that Bob S. is correct. The change in focus is sort of built into the 
engine, and a field cannot “remember” such a thing.

A fun kludge would be to create one or more overlays, however you like those to 
look, and apply them to the field of interest. These overlays can be managed in 
terms of their rects, depending on the formatted properties of the hilted line 
or lines. They can be shown and hidden as well.

I am struggling not to do this just for fun. So you do it, because I bet that 
the team has bigger fish to fry.

Re: Field highlited

[Bob Sneidar via use-livecode]

I do not see how that could work. In Windows, buttons can have the focus, which 
means a field would always lose it. 

What I do when I need something like this is I save the selection (or 
selectedChunk or some such thing) as a property of the field upon exitField. 
You could even put that in a frontScript and reference the target. Then in the 
field script re-select the text upon enterField.

Re: Convert date

[Bob Sneidar via use-livecode]

I wrote a formatDate function years ago that called this "sql date". Maybe I 
should rename it “ISO Date” or just add a case for it. There is also an “sql 
time” format in the function formatTime. This way you can put format date(the 
date, “sql date”) && formative(the time, “sql time”) to get an sql datetime 
format for a database column. They should be in the Master Library.

I suppose a lot of things could be done by the engine, but as was discussed 
years ago, what LC is NOT is a development environment that does almost 
anything. What it IS is a development environment that has the TOOLS to do 
almost anything.
