Thank you but I am not actually using a Button or an Editor, I am doing it via a FORM AjaxEvent inside a mLoginForm.
Can you send a sample (empty new mobile project) with this AjaxEvent ?

it is normal programming that only has issues (not working) with Touch Login Form.
I tested with Touch Login Form and works fine !
procedure TfrmLogin.UnimButton1Click(Sender: TObject); var st:string; begin st:=UnimEdit1.Text; UnimButton1.JSInterface.JSCallGlobal('localStorage.setItem', ['K1', st] ); // Key , Value (always string) end; procedure TfrmLogin.UnimButton2Click(Sender: TObject); begin with UnimEdit2.JSInterface do JSCall('setValue', [jsstatement('localStorage.getItem("K1")')]); // important : Key must be Quoted " " end; procedure TfrmLogin.UnimButton3Click(Sender: TObject); begin UnimButton3.JSInterface.JSCallGlobal('localStorage.removeItem', ['K1']); end;

Hi,
It grows because a new session will be created. However, after a while old session will timeout and number will decrease.
@Farshad
Sorry if i come back again.
uniGUIApplication.BroadcastMessage can reach all active (live) sessions. So the new websokets you have coded knows, for sure the total of these active sessions.
If it's not hard, could you add please, a function that would give this number?
n:=GetTotalActiveSessions;
This will simplify many things.
Thx

Dears,
You have chosen to be a developer. For what ?
the answer is simple: It's because you love everything that is:
- Beautiful
- TRUE
- and Fair
it makes you lights in this dark world. but...you are forgetting something very important: your health.
guys, we develop too much, we stay too long in front of our screens and we end up with hypertension, heart palpitations, loss of visual acuity, and other nasty syndromes...
I wanted to launch this alert, because I myself am concerned.
Fortunately, there is a solution:
Do SPORT and drink lots of water.
it's funny, isn't it!
try it and you will see: it will be beneficial for you and your family and moreover, you will develop twice as fast.
Have a good day

Perhaps you will need a table to store the data, in the mainModule's Ondestroy, you say that it is no longer active
Thank you picyka.

Thank you Farshad,
Very hapy to hear you.
I am developping an inventory mobile unigui application for supermarkets.
This application is sold by number of active sessions (users smatphones).
Example : if customer has two employees, he will buy a licence for maximum 2 actives sessions.
So, it is important to have in live active sessions with accuracy.
Conclusion :
- what is the best way to get in live number of true active sessions ?
- can websokets give this information (a function) ?
Thx

web sockets.
Hello Maestro,
Sorry for bypassing this topic.
Can we get the number of all opened (active) sessions with web sockets ?
(In classical methode : unigui demo "Session List" sometimes works, sometimes no : if i refresh browser, number grows).
Here is my function :
function TDM_Sessions.Nb_Sessions:cardinal; // works elusively var I : Integer; S : TUniGUISessions; U : TUniGUISession; n:integer; begin n:=0; S:= UniServerModule.SessionManager.Sessions; S.Lock; try for I := 0 to S.SessionList.Count -1 do begin U:=S.SessionList[i]; if (U.UniMainModule as TUniMainModule<>Nil) // Ghost Sessions and (U<>Nil) // Ghost Sessions then inc(n); end; finally S.Unlock; end; result:=n; end;
Thx.

Self signed certificats are for testing purpose or for local network.
If you want to use your domain name from web as secure https://xxxx.domain.com.br
the task is hard : you have to export your certificat from your server and communicate it to all your known clients to install it on there PC / Device !
Mmm...Asking ChatGp4
"is it possible to get a free trusted certificate for a public websites ?"
Answer:
"Yes, it is possible to obtain a free trusted certificate for a public website. There are several certificate authorities (CAs) that offer free SSL/TLS certificates that are trusted by major browsers. Here are a few popular options:
Let's Encrypt: Let's Encrypt is a non-profit CA that provides free SSL/TLS certificates. They offer an automated certificate issuance and renewal process, making it easy to obtain and manage certificates for your website.
Cloudflare: Cloudflare offers a free SSL/TLS service called "Universal SSL." When you sign up for their service, they provide you with a free SSL certificate that is automatically installed on your website. Cloudflare acts as a reverse proxy, encrypting the traffic between the client and Cloudflare's servers.
ZeroSSL: ZeroSSL offers free SSL certificates that are valid for 90 days. They provide both automated and manual certificate generation options. ZeroSSL also offers an ACME client that can be integrated into your server for automated certificate issuance and renewal.
SSL.com: SSL.com provides a free SSL certificate option called "SSL.com FREE." Their free certificate is valid for 90 days and supports both domain validation and wildcard certificates.
It's worth noting that while these free certificates are trusted by browsers, they may have some limitations compared to paid certificates. For example, they may have a shorter validity period, limited support, or fewer additional features. If your website has specific requirements or needs extended validation, you may need to consider a paid certificate from a trusted CA.
Additionally, some hosting providers or content delivery networks (CDNs) also offer integrated SSL/TLS solutions with free certificates. It's worth checking if your hosting provider has any options available for obtaining trusted certificates at no additional cost."

Asking ChatGpt4 : "Can https disturbe Ajax command ?"
Answer :
"No, the "https" protocol does not inherently disturb Ajax commands. The "https" protocol (Hypertext Transfer Protocol Secure) is simply a secure version of the HTTP protocol used for communication between a web browser and a web server.".....
"HTTPS should not interfere with the functionality of AJAX commands"...

So, i suspect iis encryption.
Can you try with a timer on your button to delay your calendar refresh.

Any suggestions?
I tested your code and works fine with .exe + SSL (Self signed Certificate).
I did'nt try it as IIS +SSL.

How are you adding your SSL in IIS ?

Humm....i have a doubt. Maybe ?!
i will buy a domaine name and try...

45 minutes ago, picyka said:
does this work for domains too?
On a local network ?
YES with ...etc/hosts file.
You have to define this domaine name on server and all client PC etc/hosts file.
Example :
192.168.1.11 mywebsite1.dev
Here 192.168.1.11 is IP Server. Thus, all your clients browsers will point to server IP with url : mywebsite1.dev
____________________
See point 2 from:
if you want DNS instead of IP, replace the Section [alt_names] by :
[alt_names]
DNS.1 = mywebsite1.dev
DNS.2 = mywebsite2.dev
On a local network, without internet, mywebsite1.dev should be defined on C:\Windows\System32\drivers\etc\hosts file :
192.168.1.11 mywebsite1.dev -

In a previous topic, we saw how to create a Self Signed Certificate with mkCert and trusted it with mmc.
That works fine but havy method !
Here we will see an other method much easier :
OK, Step by Step :
1. install the latest OPENSSL
2. Prepare a conf file (NotePad) :
[req]
default_bits = 2048
distinguished_name = req_distinguished_name
req_extensions = req_ext
x509_extensions = v3_req
prompt = no
[req_distinguished_name]
countryName = XX
stateOrProvinceName = N/A
localityName = N/A
organizationName = Self-signed certificate
commonName = 120.0.0.1: Self-signed certificate
[req_ext]
subjectAltName = @alt_names
[v3_req]
subjectAltName = @alt_names
[alt_names]
IP.1 = 192.168.1.112. Save it as C:\Program Files\OpenSSL-Win64\bin\san.cnf
- Replace IP.1 variable by your IP adress (local machine)
- if you want DNS instead of IP, replace the Section [alt_names] by :
[alt_names]
DNS.1 = mywebsite1.dev
DNS.2 = mywebsite2.dev
On a local network, without internet, mywebsite1.dev should be defined on C:\Windows\System32\drivers\etc\hosts file :
192.168.1.11 mywebsite1.dev
3. Create your 3 .pem files (like Unigui doc) but with this conf :3.1. cmd as admin
cd C:\Program Files\OpenSSL-Win64\binopenssl genrsa -out root.key 2048
openssl req -x509 -days 3650 -new -nodes -key root.key -out root.pem -config san.cnf
openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout key.pem -out cert.pem -config san.cnf
4. Copy the 3 .pem files
C:\Program Files\OpenSSL-Win64\bin :
root.pem
cert.pem
Key.pemnear your Unigui Project.exe
5. Add the cert.pem on the Windows Trusted Root Certificates (in case of a windows server).
The most important step here, wich is not indicated on the Unigui doc : (FmSoft Team, could you please add it )
Copy your cert.pem on a temporary location, example C:\cert.pem
Open PowerShell as admin
Type these commands :$certPath = "C:\cert.pem" $cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2($certPath) $cert.Import($certPath) $certStore = New-Object System.Security.Cryptography.X509Certificates.X509Store -ArgumentList "Root", "LocalMachine" $certStore.Open("ReadWrite") $certStore.Add($cert) $certStore.Close()
This will automatically add the certificat cert.pem on the trusted root certificats zone.
If you want to do it in a single ligne (1 command ), just add ; between commands
line1; line2; line3;....;line7You can verify the new certificat, by openin win + R : mmc
and go to the trusted root certificates zone
6. Run your Unigui SSL Project, and you will see the black padlock protected site.Have fun
