Delphi10.2.3: OTL, FMX, ACTIVEX DCOM i have a big problem in my code to call the parallel.Async many times i have 6 ActiveX DCOM in Delphi, and wanna call these in same time, to calculate an invoice, so in my exe i work with OTL to async all calls activex, i don't like to wait result or freeze my screen. Parallel.Async( procedure (const task: IOmniTask) var iInnerExc: integer; begin /// ***********************************************************/// { return Log} TLogSingleton.Instance().Log('Services XX calcul: Début appel.',True); //************************* PARALLEL ASYNC ****************************// // executed in background thread try // {Create instance de ViewModel annexes: XXServiceXX} mainViewModelPreCalculOTLLevel03 := CreateMainViewModelOTLLevel03Class; {Affecter le même Model principal} mainViewModelPreCalculOTLLevel03.Model := fModel; {Suscribe the observer in list} mainViewModelPreCalculOTLLevel03.Provider.Subscribe(fSubscriber); {Call VieModel.ServiceXX} mainViewModelPreCalculOTLLevel03.StartPrecalcul; except on e:exception do {call the raise, juste ci dessous, dans le onterminated Handle} raise Exception.Create('Exception lors du traitement de Service XX.'); end; end, Parallel.TaskConfig.OnTerminated( procedure (const task: IOmniTaskControl) var excp: Exception; begin // executed in main thread if assigned(task.FatalException) then begin {expoiler l'exception, captcher ci dessus} excp := task.DetachException; TErrorSingleton.Instance().Log(Format('Service XX: [Fin TASK Error]. %s:%s',[excp.ClassName, excp.Message]),True); FreeAndNil(excp); end else begin // executed in main thread { return Log} TLogSingleton.Instance().Log('Services calcul: [Fin TASK] Fin appel traitement.',True); SendNotification([actServiceXXFinish]); end; end )); the Active X Call in exe FMX: (the server activeX is integreted in framework, i don't have the source code, and i don't know haw it writen) _Dm_Dcom := CreateObject('SERVICE.XX.CLT.SERVICEXX', 'DEFAUT') as ICoServiceXX; //Instance of the DLL //CALL the function in ServiceXX_impl _Dm_Dcom.GETTRaitementServiceXX(SafeArrayIn,SafeArrayOut,FListnerForPushNotif ); //with SafeArrayIn =Json IN, and take result in SafeArrayOut; FListnerForPushNotif to send notification (Type Interface: Iunknow) the ActiveX initialization in every SERVICEXX (DLL) TAutoObjectFactory.Create(ComServer, TTest, Class_Test, ciMultiInstance, tmApartment); in this DLL; we have ServiceXX_impl unit, we have one function to call traitement in another class, we can found a communication with the IInterface (published) to send notif like this: (FListnerForPushNotif as IDataListnerForPushNotification).PushNotificationForLog('Message to send to client side'); //we have many logs types: event, Error, Exception //PushNotificationForLog, PushNotificationForError,PushNotificationForException this is my call, i repeat it 6 times, Parallel.Async( CALL01 ); Parallel.Async( CALL01 ); Parallel.Async( CALL02 ); Parallel.Async( CALL06 ); i don't need to freeze my exe, and i don't need to wait, with SendNotification([actServiceXXFinish]); or other Action like "actService01Finish", "actService02Finish" i can kown if my traitement is finished or not, finaly, if i write all 6 calls, i will fall in many and many problems, like freeze screen, and deadlock (the only solution kill the process crl+alt+supp), but if i write only one call, it will be perfect, i have, my result, but the freeze screen persist, Conclusion: 1- with many calls: problems: screen freeze, traitement not working, --> kill the process. 2- with one only call: problems: screen freeze: the "TAniIndicator" not working and the screen freeze when Delphi enter in the other DLL (activeX). Nota: the Exe is FMX (in another step it will be a Form application), the 6 services are DLL (ActiveX DCOM). plz help me

I have this problem,I have to make sure that my IO App made with Delphi Rio can appear in the list of apps with which to share a web link.For example if I am on safari and I am visiting a site I want to share this link with my app. I tried adding the management of CFBundleDocumentTypes and CFBundleURLTypes in the info.plist file but unfortunately my app does not appear in the list.Instead, there is the possibility to send the link to whatsapp, email, notes, and many other apps.Once opened my app must capture the link and use it internally.Do you know how I can do it?ThanksMassimiliano

Hi all, This morning while debugging my FMX app in Windows I suddenly started getting an EOleException within the Notification Center while initialising. onecoreuap\base\diagnosis\platform\notifications\developer\toast.cpp(2389)\wpnapps.dll!63CC11A2: (caller: 63CB5660) ReturnHr(1) tid(14e0) 803E0105 The notification platform is unavailable. First chance exception at $776F9862. Exception class EOleException with message 'The notification platform is unavailable' I've never seen this before, but it may be related to my Windows setup having updated over the weekend to v2004 (19041.388). It looks suspiciously like MS have changed the way their notification APIs work in this update... Has anyone seen this before or know of a way to resolve it? There's nothing useful on Google about this error that I could find. Thanks

Just updated a Huawei P20 phone to Android 10, and am finding the things that it has now broken! This code worked fine in android 9. Using Delphi 10.4. FileData=tfile.ReadAllLines('/storage/emulated/0/Documents/Pete/PeteADefaults.cfg') now prangs with Cannot open file "/storage/emulated/0/Documents/Pete/PeteADefaults.cfg" Permission denied. Anyone got any bright ideas? I tracked it through with F7 to FileOpen in System.IOUtils, FileHandle := __open(M.AsAnsi(filename, CP_UTF8).ToPointer, (Mode and 3), FileAccessRights) which returns -1. (Can't read files or directories either - probably the same problem)

Hi there, I'm using Bluetooth-LE, and I can see that apps might crash in RELEASE under TestFlight, while they work well in DEBUG. This happened never on older iOS versions, so I still try to find the real reason for crashing. What I think is that the bluetooth-le flag not only controls the download from AppStore, but maybe also might cause internal crash's, if not defined. I use bluetooth, with UIBackgroundModes "location", "bluetooth-cetral" and "audio" background modes, which worked well before (and still does in DEBUG), but now shows the typical permission crashes, all on modern phones and iPads with iOS13.4.1. My configuration: Rx10.3.3, XCode 11.4.1, iOS13.4.1. Maybe I need to define bluetooth-le in the UIRequiredDeviceCapabilities, or does that doesn't make any difference in apps behaviour ?

I developed an application using Delphi Firemonkey for managing my own commercial complex. I have named it EasyTenant. Overall development experience is good, though not excellent. Development was really faster because of the RAD nature. Third party components are limited for Android Firemonkey. GUI is average, not rich like other languages like Swift, Java, etc. Delphi lovers please give your feedback by looking at the screenshots. UX for me is okay not excellent.

Colleagues! We are pleased to present an updated version of the grid component for Delphi FireMonkey - FireDataGrid 1.7. The current version contains many pieces of code that have been completely rewritten to support the current version of FireMonkey RAD Rio 10.3.2. The current version of the component is fully adapted to work on High DPI monitors. The component scaling is processed very carefully (by the pixels) and does not contain artifacts at different screen resolutions. The rendering speed has been increased, and other grid operation bugs in different modes have also been fixed. Redesigned support for FMX themes and styles, absolutely any FireMonkey themes are now supported. Improved the grid zooming feature (activated by the Cntrol +"+", Control+"-" or Control + mouse scroll wheel). Zooming now works much faster. Reworked Filter panel and Field Chooser panel. Added visual effect to them. In addition, bugs have been fixed in the implementation of the TDataSet and the Grid pairing mechanism for read-only, edit modes and in adding new entries mode. You can download the evaluation version at this link. Please send us your feedback and suggestions. All your wishes will be taken into account in further development! Below some screenshots are available: FireDataGrid 1.7 uses Transparent FireMonkey Style FireDataGrid 1.7 uses Windows 10 Modern Blue Style Sincerely, Developer Machines https://www.devmachines.com

For the Google Cloud database Firebase, there was no complete library for Delphi. The new open source library FB4D closes this gap and supports the Firebase Realtime DB, the new Firestore DB, the Firebase Storage (for file storage) and Firebase Functions (for calling server functions). For authentication, FB4D currently supports email/password authentication and anonymous login. The library builds on the Firebase REST-API and provides all functionality with synchronous and asynchronous methods for the usage within GUI application, services and background threads. Both frameworks VCL and Firemonkey since Delphi 10 Seattle are supported. The library is a pure source code library and relies on class interfaces. https://github.com/SchneiderInfosystems/FB4D The library offers a wiki. Two example applications and a Getting-Started on the wiki will help you to start working with the library.

I know a lot of work was done to try and produce a multi platform version of Omni. How close is this and are there plans to complete it? Just trying to use the basic Delphi threading and I'm really missing the ease that Omni gives me. What would it take to get this work complete? A crowdfund? I'd be up for that.

I have a listview application with dynamic items, which is connected to a fdmemtable, when clicking repeatedly on any item in the listview, the application closes. If you put the listview without the dynamic items, and clicking several times this does not occur I'm using delphi 10.2.3 works ok, but in delphi 10.3 comunity, the error occurs, with android 8.0.1 Has anyone had this problem ?
