Great new documentation on file/folder architecture in v19 for projects

[Jody Bevan via 4D_Tech]

Now that I am in the office I can now pass this along for any that are 
interested and couldn’t find the new documentation and search for it. This page 
is 3 clicks into the new documentation.

Re: 4D Default Folder Structure

[Kevin Abraham via 4D_Tech]

Jorg,

I don’t think Jody even knows how to be snarky (my description for a RTFM 
answer) and why not just get him to clarify which Manual. A simple “Do you know 
which manual and section it is described in, or is it something else like a 
tech note?”

You will either get a useful answer, my experience with Jody is you will, or 
you will get nothing and be no worse off than you were, looking for something 
where you don’t even know if it exists.

Thanks,
Kevin Abraham

Re: 4D scanning

[Keisuke Miyako via 4D_Tech]

you can click on "Releases" and select a release by tag

https://github.com/miyako/4d-plugin-twain-v2/releases/tag/3.4.0

also there is a prebuilt binary, preinstalled in the sample DB when you get the 
source repository.

also you can unarchive the .zip or .dmg that comes with the source repository.

---

there are several ways to communicate with a scanner

ICA the standard on Mac and WIA is the new standard on Windows.
some hardware vendors may not provide a TWAIN driver for Windows.
I am unaware of any TWAIN scanners for Mac.

Communicating with external electronics

[nug via 4D_Tech]

I might have a an opening for a project..
I would need to be able to communicate (from windows 10) to an external 
electronic board.
running 'scripts' (do not know if the scripts will exist (LEP) or will need to 
be written (4D).

I would need to run these scripts, to run tests on another piece of electronics

4D --> board --> electronic device
device --> return results of tests to board --> to 4D

I have not done this type of device manipulation in the past.

Anyone here?

if so - what would I be getting myself into?

Thanks
Chip

Re: Communicating with external electronics

[nug via 4D_Tech]

Hi Keisuke,
There is a current system, it is slow, it requires weird interfacing between 
(yes!) IE11 and Edge 
- scanning a QR code from the screen (IE 11) to lookup(?) data used in a sql(?) 
system displaying in EDGE

IE11 runs the existing scripts using JAVA, and some (specialized?) web tools 
installed on the device
I was told that they had tried to use a modern browser (Edge, Firefox etc) but 
the scripts error-ed out.

The scripts, and (as far as I can tell) all the software is in-house and 
proprietary.

Re: Communicating with external electronics

[Keisuke Miyako via 4D_Tech]

maybe it is using ActiveX

https://en.wikipedia.org/wiki/ActiveX

the script could be invoking another OCX component that does the actual heavy 
lifting. just a guess.

Re: Communicating with external electronics

[Keisuke Miyako via 4D_Tech]

I suppose the scripts are written in Python or some other language.

the script language is probably not important. 
I imagine it is published as a "language neutral" sample code,
not as a Software Development Kit or middleware.

you might even be able to translate it to native 4D for HTTP or RS-232C, 
NTK for TCP, UDP, etc. 
I would not recommend Internet Commands for new development.

it is more important to know the communication protocol for the device.

v18 Background Image / Win32API

[Ben Sokal via 4D_Tech]

Hello,

Since Win32API now seems to be obsolete, how can we easily set the background 
image ala gui_LoadBackground? I tried the Miyako replacement on github at 
https://github.com/miyako/4D-Win32API/releases/tag/8.3.v18 but it did not seem 
to work (I think the command ran but the background did not change). How have 
you handled setting a background image change after upgrading 4D to latest 
versions?

Thanks!
Ben

Re: v18 Background Image / Win32API

[Keisuke Miyako via 4D_Tech]

the plugin replaces the background by intercepting the PAINT event for the MDI 
window.

4D is Altura-free since v17

https://blog.4d.com/complete-windows-64-bit-product-line-is-now-altura-free/

which drastically changes how (or if at all) plugins can "hack" the GUI.

I think it might just be better to migrate the application to SDI mode if you 
don't like the MDI window.

Re: Communicating with external electronics

that makes sense - as active x is (as far as I am aware) depreciated in all 
browsers newer then IE 11
