    Sending email

    Hi Mohammed,

    Looks good and neat. But beware if you are going to send this on behalf of rivierea-tours from YOUR gmail account WITH THE SENDER read@riviera-tours.net.
    Then it will be seen as spam. Also when the recipient gives a replay, the mail will not arrive at read@riviera-tours.net if nothing arranges. 
    Maybe it is an example and in practice it is arranged differently

    A number of guidelines apply to (bulk) mail:
    - link to domains, not IP addresses in email html body.
    - do not include JavaScript in email html body.
    - do not include embedded Object (ActiveX / Flash) in email html body.
    - don't include HTML forms in email html body.

    Providers such as hotmail, gmail, yahoo impose many restrictions on sending e-mail. You do not have this when you send mail
    from your own domain or take one of the options from my previous message

    Some guidelines

    Hi,

    Be aware that when you send a lot of mail VIA gmail (bulk mail), you will soon be blocked because of spam.
    Much is then a relative concept because mail is monitored on the ip address / domain from which it is sent,
    number per minute, hour, etc., sender and replay address, etc.

    If you really want to use it for business to send mail from your application, you can better:
    1. send mail from your own domain, so via the domain where your application is started.hosted
    2. use an smtp / relay server
    3. send mail via an account of the customer

    Option 1: send from your own domain
    You can then create an email address for each customer. Suppose your application domain name is "myapp.com". You have 2 customers who use your application. These are the companies:
    - company-X (have their own website / mail)
    - company-Z (have their own website / mail

    You now create an e-mail address for every customer, namely:
    - company-X@myapp.com
    - company-Y@myapp.com

    When the company uses the e-mail functionality within your application, they use the above e-mail address.
    Mail will now be sent FROM your own domain name WITH the same domain e-mail address, namely @ myapp.com

    The next step is to ensure that when a reply is given to this e-mail, it also reaches the relevant company.
    After all, one answers to Company-X@myapp.com and the mail ends up in your mail environment.

    You now put a forward line on the mailbox of company-X@myapp.com whereby the mail is forwarded to an email address
    of the company, for example info@company-X.com.

    Now the mail is forwarded to the company and the communication takes place directly between company and customer
    who has replyd on that mail. Company-X must, however, submit an spf record in their web environment take from myapp.com.
    This indicates that company-X trusts myapp.com when sending e-mail.

    Option 2: use a relay server
    This is the most reliable way of sending mail. A smtp provider has everything set up to send mail optimally, continuously adapting the changing
    mail rules of eg gmail, hotmail, outlook, etc. All you have to do is create accounts per customer, etc. Examples of smtp / relay server providers
    are for example (there are in every country):
    - https://www.sendinblue.com/
    - https://www.mailchimp.com/
    - https://www.serversmtp.com/
    - https://sendgrid.com/
    - https://www.flowmail.com

    You then pay an x amount for an x number of mails to be sent per month, usually it starts at 15.000-20,000 per month.

    Option 3: use mail server client
    This option is also applied, but may result in mail being seen as a spam.
    You ask your customer to create an email address with a password. What you actually do is use this data to log in to the mail server
    of the customer and send mail via that mail server.

    All 3 options have advantages and disadvantages. Sending mail from a different mail address than your domain (where your application is located)
    is often seen as spam. Especially when you are going to send multiple mails to the same e-mail domain within a certain time.
    This specific time is different for each provider (gmail, hotmail, outlook).

    Do not forget to include the correct header information in your mail, especially when you send mail using options 1 and 2.
    Header information is important because the domain is often mentioned there and then you run the risk that app domain and
    mail domain are different to be.

    You also have a number of other settings such as Dkim, Dmarc, Tls that affect the security of mail.

    best way to compare time values

    in General

    Posted

    Indeed, no date is used because the times are seen as a reference framework.

    - morning period falls between 7 a.m. to 12 p.m.
    - afternoon falls between 12: 00-17: 00
    - evening 17: 00-21: 00
    - night between 21: 00: 02: 00

    When filling the period times, a check must therefore be made to ensure that the start time is not greater than the end time.
    That goes well until you use hours in combination of BEFORE and AFTER 00:00


    In the actual planning, someone selects a period and specifies a working time. It is then checked whether the specified working time
    falls within the period times.

    Maybe an option to use 2 dummy date fields that are not used in the software

    You will get something like:
    - start Date
    - startTime
    - endDate
    - endTime

    Dates are always the current date and when EndTime is> 00:00 then EndDate + 1

    Using a DateTime field in it is again cumbersome to use ReplaceDate where you only change that date.
     

    Would be nice to have a time slider :) with begin/end time

    Hi

    What's the best way to work with time controls. My table now has 2 fields of type time, namely:
    - startTime
    - endTime

    The user must enter a period with a start-time and end-time.
    For example :
    Evening 6:00 pm - 10:00 pm
    Night 10:00 pm - 2:00 am

    I would like to check if the startTime is not greater than the endTime because then it is not correct. This works well as long as the endTime is less than 00:00.

    In the situation such as 22:00-02:00 that does NOT work because startTime is greater than endTime but it is a valid period.

    We do NOT use a date because they are block times for a period.

    What's the best way to solve this including a controle

    Hi

    To choose the correct version, you have to click on the 'Compare TSplus Edition' button at https://tsplus.net/store

    If you DO need a print option, you will need at least the Printer, Mobile or Enterprise. So it is a matter of weighing up.

    If you want to use ssh and https, you already need at least the Mobile version.
    If you want to give access via / from an iphone / ipad / android device, you need the Mobile version.

    We use the Enterprise variant ourselves because we use the TSplus portal function where the user logs in
    and the application is started. I don't think you have this in the lower versions.

    You can run the demo https://tsplus.net/how-to-use-web-application-portal to get a feel for it. You can also
    download and install a trail for 15 days / 5 users
    https://tsplus.net/secure-remote-access#enterprise-edition

    If you have a Windows 10 PC with some good specifications, you can also run it yourself at home
    https://forum.tsplus.net/forum/viewtopic.php?f=3&t=4671

    Regarding the VPS server, there are different opinions about this, but in my opinion there is no right or wrong.
    There are many providers and you have to take what suits you. You just have to look carefully at what they offer by default.

    A VPS server at Contabo starts at € 3.99, but as soon as you choose Windows, € 5.99 per month will be added.
    With other providers you will see all-in prices including Windows. It's the small differences.
    In addition, it is also important how resource intensive your applications are and whether you need a lot or
    little cpu / memory / bandwidth. This partly determines the price of your VPS server.

    You just have to compare the different vps providers and experiences on the forum can help ... or not.

    Hi

    TSplus works very well. We have been using it for a number of years to make our vcl desktop applications available via the browser.
    This as a transition phase to the full web.

    Here you have a good overview of the prices and options
    https://tsplus.net/store

    What you need is one - I think it can be done on a W10 machine depending on the number of users, otherwise a Windows VPS server and a url so that it can be accessed from the outside.
    VPS servers are not that expensive anymore with Windows.

    A new uniGUI wiki / knowledge base is operationeel

    in General

    Posted

    Dear forum members

    I had the idea for some time to set up a structured wiki / knowledge bank for uiniGUI. From today http://www.uniguiwiki.com is therefore operational.
    It is a wiki / knowledge base where as many ready-made solutions as possible can be found in a structured way.

    The forum works well, but it is sometimes very difficult to find solutions. With the help of this wiki / knowledge base I want to add some structure.

    Unfortunately, you cannot create a wiki post yourself, this to preserve the structure as much as possible and to prevent proliferation.
    Maybe this will come in the future. However, it is possible to create some authors who want to post solutions or help.

    Everyone may have code, tips / tricks that they want to make available on the wiki. I therefore depend on your help to fill this wiki as a
    central knowledge base. For this I have created an 'upload facility' where you can upload examples. I will then view, assess and make this
    available on the wiki.

    To access the wiki / knowledge base, you must create an account and then you can consult the wiki / knowledge base and upload any code.

    If you have any suggestions, please use the contact form on the site or send a PM via the forum.

     

    Regards Peter

    Maybe this can help...a chrome extension

    https://eid.belgium.be/nl ...when you search you got the text:
    Unfortunately! The eID software is currently not available for mobile operating systems. 

    Normally you need for those specific reader additional drivers and a sdk, almost alway Windows.

    I know Zetes does Identification and Person Identification, may the have some support

    Is it possible ....nfc scanning & raspberry-pi?

    in General

    Posted

    Hi
    I am looking for a solution for nfc scanning with a raspberry pi and an nfc reader. The nfc reader can be a connected usb reader or an nfc shield for the raspberry-pi.
    We are now using this based on a Windows pc, win32 application and usb nfc-reader. I want to have some kind of stand-alone solution, see image, based on uniGui (if possible)

    How does it work in a stand-alone situation:

    • all nfc tags are in 1 central database
    • guest comes and scans the nfc tag
    • application checks for validity and a few more things. When the nfc tag is valid, the guest can enter
    • data is updated in central database

    What do I want?:

    • all nfc tags are in 1 central database
    • a raspberry-pi with an nfc reader (we already have)
    • raspberry-pi gets a name, for example the name of the scan location such as room 1
    • nfc tag is read and checked for validity and when valid a lamp lights up (already working)
    • data is updated in central database

    Ask:

    • Can this be done with uniGui and the application is then centrally installed on the server (as normal) and started via a browser on the rapberry-pi?
    • Or must the application be installed locally on a raspberry-pi?
    • Must i create a Linux variant

    We are still looking at how to set up the connection to the central server. At a festival, the server is located locally and a local network is set up.
    Another option is based on 3 / 4G / LTE. This is because the network distances are sometimes greater than 100m on a festival site

    Reading NFC tags is not a problem, this is the same as keyboard input.  
    Suggestions and ideas are welcome

    Regards Peter
