NT 14.13  C 11.
I am going to run a Net Talk Secure Web server.  All data is on server.  Users will interact with the Server via mobile devices.  I will have remote windows terminals which will only DISPLAY messages and do actions ( like drop things) upon direction of the server after the mobile user has authenticated themselves.  The Kiosk can run a Clarion APP and can have a login to the NT web server.  The kiosk will ONLY DISPLAY messages from server and do actions requested by server.  There is NOT a lot of communication going on between Server and Kiosk.  Interactions may be 100 in 24 hours.  So, not a lot of traffic.  questions:
1. Should I implement a Secure Socket between Kiosk and NT server - this would be open all the time?
2. Is there a better way for server to send messages to the KIOSK in response to Mobile user making requests at the Web server.  So, response has to be timely.
Trying to figure out the best way to implement on NT server and remote Kiosk.   All help appreciated.

Web Server - Ask For Help / Hiding a Tab
« on: November 20, 2023, 07:01:28 AM »
Hi All.  Trying to hide a tab when a form opens depending on the security level of the user ( user vs administrator - user < 900,  admin > 900).
On the Form, the FIELDS tab shows the tab name, EQUATE and HIDE IF columns.  (Implies that I can set a condition to HIDE the tab).
However, FORM TAB has the "Tab Hide IF: greyed out. 
What needs to be set to be able to use the HIDE IF condition?

Web Server - Ask For Help / Mobile App example from CIDC 2023

HI Bruce,
Did you include the code from your Mobile App that you built for Net Talk Training  on site at CIDC 2023.  I can't find it in downloads or materials.
Is it included in NT14 somewhere?
#2 - I specifically am trying to get a handle in IDB database record that goes on the mobile device.  Trying to see example of the fields it uses and additional fields that I might want to add.

Web Server - Ask For Help / Near Field Communication - Iphone and Android
« on: November 15, 2023, 01:40:37 AM »
Hi All,
Does Nettalk and PWA provide access to Near Field Communication?  I am trying to ascertain that the person at the kiosk location is actually the person who needs to be there - e.g. to pick up a key.  One way is to have the users phone read an NFC tag in the kiosk and report the results.  Is this something Net Talk can handle?  Other ways to verify the correct person at kiosk just using their cell phone - no screen on kiosk - just camera, maybe Near Field to read and maybe a numeric keypad?
Any thoughts?

Hi All,
Running NT 14.08 and Clarion 11.0.136.   I need to communicate to and from a NetTalk Server and a remote computer running windows ( actually a type of kiosk).  I am going to run a clarion exe on the remote machine.  Instead of trying to tie the remote computers to the tables on the Web Server I am looking at an alternative way of sharing very small amounts of data.  e.g. When a user is verified on the NT server, I want to let the remote computer ( and there will be several remote computers so I need to address a specific remote computer ) have some limited data fields.  Also, when the end user activates the remote computer - actually a kiosk type setup - I need to send the data to the NT server for verification and depending on verification by the NT server, send some limited data back to the remote computer (kiosk) and then the remote computer can perform some duties.  I am not sure if this is a net simple communications need or a set of APIs.  I am sure folks have done this and can offer some suggestions.  The scenario is that the end user can verify themselves with a QR code on their mobile phone which is connected to the NT server OR they can use a RFID on the remote computer( kiosk) to verify locally.  I need to share information between these two. Any insights will be appreciated.

Web Server - Ask For Help / Can Net Talk APP control a local serial port.

 :NT 14.08
Clarion 11.0.1136
I want to be able to send and receive characters from/to a local serial port. I guess it would be like reading a serial barcode reader. 
1. Is it doable?
2. What are the steps and the tricks.
Many thanks,

Using NT 14.07  Clarion 11.0.136
When taking a photo with a mobile phone - I remember Bruce showing I think a button which allowed the end user to be able to switch between Front and Back camera depending on what they wanted to take a photo of.
I tried setting up a Button but that did not work.
Anyone can supply details on how to allow the end user to change the camera on their mobile phone that they are wanting to use?

Web Server - Ask For Help / PWA question
« on: October 19, 2023, 02:18:38 AM »
Do PWA's which are CONNECTED all the time run only the Javascript code on the phone or can they run the clarion code on the website? Or do they do a mix of both?  Trying to get a handle on this as I am making a PWA which will be connected all the time.

Still trying to track down the problem with saving webcam pictures in NT14.

Web Server - Ask For Help / Mobile Web App Icons

Hi Bruce,
In one of your CWIC pre conference educationals you mentioned the source that you got your icons from.  Can you give it here - can't find it in my notes.

Web Server - Ask For Help / WebCam problem still NT 14.06
« on: October 08, 2023, 06:33:54 AM »
Still cannot get Webcam to save picture correctly.  C11.0.136 and NT14.06.
Webcam Demo Example 79 does not work correctly.  My problem is in saving the picture and then re-displaying it.
Out of the box, example 79 seems to be trying to save a Binary string to DisplayPhoto name and NOT the assigned name of the file which was uploaded.
I modified the Settings dictionary and added a blob field(binary).  I tried to save the webcam picture to the binary blob.  Nothing saved.
So questions:
1. Can I save the picture name to MAI:MailBoxPicture AND a BLOB(Binary) field at the same time?  OR is it 1 or the other?
2. If I want to save it into a BLOB, how do I set up the fields to display from the BLOB and not a saved file name?

Web Server - Ask For Help / Mobile App that is NOT Disconnected
« on: September 11, 2023, 11:49:36 AM »
Hi Bruce,
You mentioned that a Mobile APP ( PWA ) would run clarion code if it was connected all the time.  I am making a PWA which will run ONLY if connected. 
1. Do I need a sync server in that case - seems like I wouldn't?
2. The PWA would run only if connected - therefore it seems logical to test for connection and run if there is one. If no connection, display a message that the app will run only when connected to the internet.
Can you help with information to sort this out please.

Web Server - Ask For Help / Webcam picture name field incorrect in NT 14.04
« on: September 09, 2023, 06:17:25 AM »
Using NT 14.04 and Clarion 11.0.13639
I am using Webcam example 79.  It displays the webcam image and does Take a picture and displays it in the Display image.  However, in NT10 it stored the Display image name - something lile:  \web\uploads\4881ffg2.png.
in 14.04 it stores the imageName as:  data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAoAAAAHgCAYAAAA10dzkAAAAAXNSR0IArs4c6QAAIABJREFUeF7svemXZeV15rnvGHNEZuScyZAMyZgMQkgMEpYsa7CRbMlyq2RAgOyqaq8uu7pWfeuuqv5c/Qf06tWu1R+6293t8upy2a72IFqTJUBIjAIhSDKBnGOeI+489XqeZ+9zTgSRCAmEEriXFUTGHc55z3vOve/vPnvvZ
There is no image in the \web\uploads  folder.
Seems like it is trying to store it as encoded within the Cstring field which should have the file name.

I have a Web App running on port 88.
I tried to run a second (different app) on port 90.  Got this error:  "Warning <Display Name> cannot load as another instance is already running."
I remember this from long ago.  The DISPLAY FIELD name has to be different.
BUT where Do I find the NAME field for this.

Web Server - Ask For Help / JavaScripts problem
« on: September 06, 2023, 06:45:05 AM »
NT 14.04.  Clarion 11.1.13744.
I have my NT app running nicely on my development machine. 
I started a test deployment on a server and I am getting all kinds of javascript loading errors. I have tried lots of things but I think that there is something fundamentally wrong with my setup. I even put Clarion on the Server and compiled it on the server and same problem.  My development machine is using OneDrive for the application development storage.  I think that there is a setting pointing to the Javascript files that is messed up on my server.  Console errors are attached.  Can someone give me some insight into how to fix this Javascript loading problem.  BTW, I have the Visual Studio Runtime installed on my server.
