Re: Autodiscovery of LAN devices

[Richard Gaskin]

Thanks, Alex.  I may need something more refined later on, but for now 
my modest needs appear to be well met through simple brute force:


At the moment this is for some network tools for students to use in a 
classroom.  Ideally there would be no Internet connection, just a local 
network of a small number of devices all using a single wifi router.


I had experimented briefly with a UDP broadcast, but ran into an issue 
in which it seemed the server wasn't receiving the message.


Before spending more time on that I tried a different tack with TCP.

With Bob's IPCalc function I'm able to get the first and last addresses 
of the local subnet.  His function needs the local IP and subnet mask, 
which can be obtained on Mac and Linux with a shell call to ifconfig, 
and on Win with ipconfig.


Armed with that I just attempt a TCP connection to each device in turn, 
looking for a specific reply.  When I get what I expect, I know I've 
reached my app on the other machine.  Takes less than a second to scan 
the network.


Done in a few minutes' work.

Of course this won't do much for mobile devices (how do I get the local 
address on iOS and Android without shell?), but since UDP is off the 
table there anyway I'm no worse off, and can at least get started with 
laptops and Raspberry Pis happily talking to one another...

If you need to discover instances of "your own" server on the LAN, then
there may be an other solution. depending on how well defined "my

Basically,

- every server listens for UDP packet on some port

  - client sends a broadcast UDP request to that port

  - servers respond.

This assumes that you can *reliably* depend on your LAN being a single
subnet, that your LAN is not too huge :-), that all servers are within
your control and you can add such a listener to them, etc.

NB - this is only a solution for desktops (only they can send broadcasts).

For ios you can use mergSomething :-)

For Android, afaik there isn't anything to allow broadcast transmission,
so I think your only solution for now is to move to a
broadcast/advertisement approach - servers (currently desktop only, you
said) must advertise their service, and Android clients can listen for
such adverts and thus learn where the service is available. This is only
feasible if you know of limits on the number of servers & services - or
(for-android as-client) if you are willing to add significant complexity
and have proxy-servers handle it for you; you can do that in an
automatic way (i.e. no configuration needed) but it is complex.

Don't even start down that road unless you need this for Android before
the timeframe for either bonjour or sockets on android.

Re: Autodiscovery of LAN devices

[Bob Sneidar]

Unless network devices are listening through their firewall, this can prove 
difficult. Spiceworks has a network scanner system that is extremely robust, 
you may want to look into how they do that. Basically, you can attempt to 
connect using WMIC on Windows, SSL on *nix systems, snmp for printers, 
switches, etc. and HTTP if all else fails. 

To do this however, you need credentials to actually get any detailed 
information. Windows is about as friendly a thing as you are going to find. You 
can find out a lot about a Windows workstation without administrative 
credentials. Apple, almost nothing. Printers, whatever you need essentially, 
using SNMP traps. 

If all you want to know is who is listening on what ports, telnet works pretty 
good. something like telnet 192.168.1.5 25 will tell you if something is 
listening on SMTP for example. It's just a matter of knowing all the standard 
ports and scanning for them. 

But LC does not seem to be the ideal thing for this. Instead, you may want to 
look into nmap. They have command line features for doing exactly what you 
want, minus the actual connection bit.

Autodiscovery of LAN devices

[Richard Gaskin]

I'd like to have an app automatically discover and attempt connection to 
other devices on my LAN.


Looking through the list archives I can find a few half-solutions, but 
not one which works well across the platforms LC supports (Mac, Win, 
Linux, iOS, Android).


At this time the only things listening on a port will be desktop 
computers, but I still need to be able to connect with them from any 
other device on the local network, and down the road I may want to allow 
even handheld devices to take on an accept role.


Any robust, tested solutions available?

Zealous "Save" prompts

[Richard Gaskin]

Any of you seeing inappropriate prompts to save stacks in v9?

I'm occasionally seeing them for plugins and dialogs, places where I may 
have changed some text but not when the stack was toplevel or in any way 
affected by the pointer tool (plugins, things like that).


Unfortunately I haven't yet pinned down a recipe to report it.

If you've seen this let's discuss to see if we can come up with a simple 
recipe so it can be fixed.

command is an error message if it failed rather than anything returned by 
openCard.

Cheers

Hi John,

If you are using Indy or Business, mergMK is exactly what you need… MapKit for 
iOS.

Best,

Using Apple maps on iOS

[John Allijn]

Hi,

I’m working on a mobile (iPhone) app and I’m a bit stuck at the map portion of 
it. 
The app is supposed to show a map with POI’s. when you tap the POI, the app 
should go to a card with information. 
After a bit of trial and error I was able to make a browser object on my card, 
but whenever I put an apple map URL in it, It will jump to either google maps 
or apple maps, depending on the scheme used. Further more, I don’t seem to be 
able to show multiple POI’s on the map.

Has anyone worked with this kind of map-usage before? is there a way to embed a 
map into a card and use the POI’s to navigate/jump to different cards?

thanks in advance!

John.

It's determined based on the system display scaling setting.  It will kick
in when your "program [is] blown up to 150% by the system rendering", as you
mentioned in a previous e-mail.

This is how we get the splash screen image and menu bar icons to look good
in LiveCode 9 DP 1 on my HiDPI Windows 10 laptop, for example.

Hi Peter,

as far as I had understood an 1920x1080 display not yet a Hi-DPI display and
wouldn't trigger the Hi-DPI function, or am I wrong that this option already
would take action with such an display?

1) Make your images linked to an external image file
2) Add two files: myimagename.png and myimagen...@extra-high.png
3) LiveCode will automatically use the latter on HiDPI displays

AW: What do I have to prepare if enabling Hi-DPI scaling for Win standalone?

[Tiemo Hollmann TB]

I have a customer, who complained that everything in my program, including
the text looks so blurred. I made some tests with an Dell Inspiron notebook,
which hasn't a Hi-DPI display, but a very crispy 1920x1080 display and
compared a main window of one of my LC programs, once compiled with LC 6.7
and once with LC 8.1 and the Hi-DPI option on.

Since this isn't a Hi-DPI display, probably the option has no influence and
both programs look pretty similar and sharp. But since 1920 x 1080 is pretty
small on a 13'' display, most users of such kind computers set the text size
system setting to 150% (as also recommended by Dell). Running this crispy
display at 150% text size, "all other programs still look fine and crispy",
but the comparison of my both program versions show pretty different
results. My LC 6.7 program blown up to 150% by the system rendering looks
completely blurred, every text and all bitmap images look smooth, but
blurred. - This is obviously that what my customer was seeing.

Due to the new rendering machine of LC 8.1 (or was it already 7?), all text
in my LC program looks sharp and fine, as in the other programs. BUT, my
bitmap images (some with text inside) look terrible. In opposite to LC 6 all
edges in the bitmap images look sharp, but pixeled and stepped and actually
worse as in LC 6.

Since this isn't a thing of Hi-DPI, I am not sure if and what I could do, to
make this better. Is LC already vector image ready for all cases (plain
image on screen, image as button icon, image in text?) Beside this is pretty
much work for me, to re-design all images as vector images, I am not sure,
if this is the only solution, or if I could get back the smooth and little
blurred appearance of my bitmap images, like in LC 6 with any trick?

How do you handle this?
Tiemo

Betreff: What do I have to prepare if enabling Hi-DPI scaling for Win
standalone?

Hello,

 

Up to now I haven't enabled the Hi-DPI scaling for Windows standalones and
since I don't have a hi-dpi monitor I can't test the difference of my
standalones.

Do I have to prepare anything different, if I enable the hi-DPI scaling? Is
it necessary to exchange all images by images with higher resolution?
(180dpi instead of 96 dpi, though dpi actually is a thing for print work?)

I assume if I would show my existing program (non-hi-dpi) on a high DPI
monitor, all images will look blurred. But will they look sharper, if I keep
all images and just enable hi-DPI scaling without any new images? And is it
recommended to enable it by default? (If yes, why do we have this option at
all and it is not fixed standard?)

 

Any insights and experiences welcome

Tiemo
