If Hyperserver is used to start an application and if the application crashes for any reason, will Hyperserver restart it automatically when it is unable to communicate with the application after a certain period? This is for either the ISAPI or service types of Hyperserver. -- Frederick (UniGUI Complete - Professional Edition 1.90.0.1552)

Yes, I did after reading the above messages. Your postings are very informative and I will keep a record of them. Thanks.

It is good thing we don't have the restriction here. We have many Internet access providers to choose from and furthermore, if such a restriction was imposed, the consumers here would raise a big fuss.

Thank you all for the information. I managed to access the application using the public IP address by port forwarding the port number in the router to the local IP address of my computer. In addition, since I had two firewalls running, I had to create incoming rules for both firewalls to allow access to the TCP port number.

The IP address of the PC refers to the network IP address? Interestingly, if the UniGUI application is hosted with IIS, this does not need to be done. Do I need to do this for standalone and service UniGUI applications?

I have a public IP address of say, 210.209.123.182 and my UniGUI application runs on port 8077. From my phone, I can ping the IP address but when I type http://210.209.123.182:8077 in the phone's browser, it will not connect. I have turned off all firewalls and even allow incoming access to port 8077 in Windows Defender Firewall but there is no change. What am I missing here? Note: Connecting locally using the network IP address works fine. -- Frederick (UniGUI Complete - Professional Edition 1.90.0.1552)

I have the following setup with 3 sessions running:- IIS --> HyperServer --> UniGUI application If the application crashes in session 1, will the remaining 2 sessions crash as well? -- Frederick (UniGUI Complete - Professional Edition 1.90.0.1552)

Have you tried clearing the browser's cache?

You could try using TUniURLFrame with another web browser to see if the same problem with blank pages occurs. I sometimes do get blank pages but ultimately, it had something to do with my queries or coding.

I do not have a fix for this as technical support did not provide a solution. I think that TUniPDFFrame is based on PDF.Js, a third-party solution, and there could be some coding issues with it. Currently, I use TUniURLFrame and the extra page does not appear. Maybe it is based on the web browser's internal engine and this problem does not occur. I like TUniPDFFrame but I could not wait.

I suppose that this is the only way. Thanks.

I have a TUniDBGrid with the following properties:- Web Options | Paged = True Web Options | Page Size = 25 There is code in the OnColumnSummaryResult event that displays the total of a column. If there are 26 records, I get two pages but the column summary is displayed twice in each page with totals of the column pertaining to that page's records. How do I get the column summary to only display in the last page with a total of all the records in all pages? -- Frederick (UniGUI Complete - Professional Edition 1.90.0.1551)

Thank you for the information. I'll look it up.

I never learnt it. I just depended on the assistance provided by peers and technical support here whenever I have a question or encountered a problem. It's all copy and paste.

I did not get help on a general basis but if you have a specified problem or request, post your question here and you should get help for it. Alternatively, you could search the forums. Based on the forum messages, UniGUI requires the use of JS code for quite a number of functions and if you do not know JS (like me) and without the assistance of technical support here, it may be a problem using it.

Thank you for the confirmation.

I'll leave the reading of the OpenSSL documentation to security enthusiasts 🙂. Us mere mortals need only know that we can use the Indy components in a secure environment as long as the two SSL DLL files are copied to the same directory as the application.

I did use Indy components initially for test connecting to my mail server but it failed at the SSL handshaking stage. For some weird reason, connecting to a Google mail server did not pose a problem. After revisiting Indy (because ICS does not work) in a new test project, connecting to my mail server and Google's mail server in 32 bit mode resulted in no errors. However, recompiling in 64 bit resulted in the same problems in my full project. I suspected that there were some issues with the SSL libraries and I read from a Google search that the SSL DLL files as installed by UniGUI should be copied to the app's output directory. I did so and now, both mail servers can be connected to in 64 bit mode without errors. Note: I am curious as to why the SSL DLL files in the Window's System32 directory are not referred to by the UniGUI app.

This statement confirms that ICS was incompatible with UniGUI 11 years ago but it would have been reassuring for technical support to confirm that ICS does not work with UniGUI today.

I created a test project that uses Overbyte's ICS to connect to a mail server. After entering the parameters and clicking the Connect button, nothing happens. The event that is attached to the SMTP component is never called. However, when I create the exact same project in a VCL application, everything works as expected. What am I missing here? P.S. I have attached the testcase. -- Frederick (UniGUI Complete - Professional Edition 1.90.0.1551) icsconnect.zip

I haven't had any downtime issues with the VPS since I have used it for 2 years but the production application I run on it is not used often. I did read somewhere that a VPS is not really suitable for production use with a high number of users because of its shared nature. In any case, thanks for the heads-up. I will monitor it when my other application which I expect to be used by more users at the same time goes live in a few months. With so many VPS vendors available, it would be easy enough to switch or I could go with a dedicated server solution.

What issues do you have with Contabo? I have a single application hosted in a production environment with them and so far, the only issues I have currently is the slowness in delivering pages and long customer service response times. The first issue could be due to latency problems since they are situated in Germany and I am in the Asia Pacific.

Thank you. This works as expected.

Is there a solution for the above error? I am still getting it for version 1.90.0.1549.

There were no errors but I noticed that whenever I clicked the "Load PDF" button, the download status was updated. It turns out that my setting for PDF file types was to save the file immediately instead of having it opened in Firefox. Changing the setting solved the problem Thanks for your assistance.
