You can print to PDF and then show this to the user. I can't tell you how to do this from the top of my head though.

Delphi Supports Android API 33 Via Yukon Beta (embarcadero.com)

Converting such code to Delphi is normally not the best approach (a lot of work and you loose connection with the original code). You can better make this code available to your Delphi application as a COM object or as a service.

At the Dutch Delphi day a few weeks ago, Bob Swart presented CodeSite which can do this (CodeSite - RAD Studio (embarcadero.com)). Especially the real time tracking whereby log events were sent directly to a central server showed that user interactions with the application could be tracked in (nearly) real time.

What exactly do you want to 'automate'?

You are accessing variable 'Components' as if it where an array, but it is declared like a reference to a TComponent. I think you want to redeclare your function like:

type
TComponentArray = array of TComponent;
function SetDBSessionNames(const ComponentCount: Integer; const Components: TComponentArray; const sSessionName: string): boolean;

Yes we have this issue too, our icon is not transparent as well. We haven't investigated it though and accepted it so far. 

Thanks, will check it out

I can remember seeing a method or class in Indy which allowed me to connect an incoming socket to an outgoing socket directly so that data flows from in to out. However I can't remember the name or file where I can find it. Any ideas?

Checkout RemObjects Elements, you should be able to re-compile much of your Delphi code to .Net (Elements. Build native projects for any modern development platform, using the language(s) of your choice. Oxygene (Object Pascal), C#, Swift, Java, Go. | RemObjects Software).

Support for appinstaller is available since W10 (see Troubleshoot installation issues with the App Installer file - MSIX | Microsoft Learn). We have had issues in the past with the auto update feature (users had to restart their computer before the auto update would work) but that has been fixed by MS.

More than 10% from 12500 installations in last year are Windows 7 and 8

We still support both update processes side by side having two separate installers. If you need to support W7 and W8 I think there is no way around this.

In the past we always did our own auto updating using a similar approach as presented here (rename exe, download new version, then restart). This works as long as the the application is installed inside the user profile, not when it gets installed in 'Program files'.

Nowadays we let Windows handle this using an MSIX installer accompanied by an .appinstaller file (you can configure auto update behavior from the appinstaller file). In my experience, using the .appinstaller gives a much better user experience than any other method.

Be careful with Mida. From my experience the software is not working. Although it can still be purchased, it won't run because at startup the software cannot contact their license server and then stops. I tried contacting the developer many times, never had a response.

I think this should work:

var F: IFoo;

Supports(DialogManager.CreateDialog(IMyDialog), IFoo, F);

Yes, works with FMX and VCL, but Windows only.

The first step would be to get more detailed 'crash' information. We use madExcept in all our software to do this (there are others too) which provides a solid stack trace when an exception occurs. Without such info you don't know what to look for....

In Citrix users are not allowed to start executables if they are not properly installed inside the system. Normally users are not allowed to install software themselves. So you should discuss with the hosting company if they can install your application into the Citrix image so that it becomes available to the users. If that is not an option, you can make your application available online using software like Thinfinity.

Tks.  I haven't had anything like that reported to me.

ok, good to hear, maybe our setup is different. We use a Windows 2019 datacenter, Gen 2 server.

We now have a single server running, but are moving into a load balanced multi server setup. Do you have any experience with this?

We used TSPlus Remote Access (https://tsplus-remoteaccess.com/?lang=en) and we are satisfied with the result.

This looks more like a remote desktop solution and needs local software. With Thinfinity we can access a single application from the browser on the remote server. There is not even a login process required.

Yes I mean Thinfinity, we have issues with starting new sessions, sometimes they will not launch (they hang on the 'loading' screen). We are working on this with them so I expect it to be fixed.

Hello,

Which solutions are available to virtualize Delphi applications so that it can be accessed from a browser?

We are currently using VirtualUI (https://www.cybelesoft.com/) but experience some technical issues. I wonder if alternatives are available.

Thanks for your tips and ideas

Is your answer that it is impossible (or very difficult) to create a stable android app using Delphi

To comment on this question,  we are using FMX and Delphi (11.1) to build a Windows/Android/IOS app. We are pretty satisfied with the support, development process and stability of the application. One source/multi platform works very well for us. See this link Lynx X - Apps op Google Play.

You are welcome to talk to our developers to share ideas or learn how we do stuff with Delphi 11.1

Yes, it works OK now.

Thanks for taking the time explaining the workings of Http and Indy. I have learned a lot over the past few days. I now have my reverse proxy working.

Greetings,
