If anybody here knows the details about the Dynamic Abstract Factory created by Spring4D and want to help I'll be appreciated. PS, Just in two days I have seen several Spring4D related posts by others group members since my first spring4D related question posted few days ago, is it a coincidence ? :D https://groups.google.com/forum/?hl=en#!topic/spring4d/thcQf0x2zFY

Blog post: ScannerMApp: a QR/barcode scanner app with Delphi, ZXing and TFrameStand If you are interested in mobile apps and/or barcodes, here it is my latest blog post. Demo video available, full source code included. :-) https://blog.andreamagni.eu/2017/06/scannermapp-a-qrbarcode-scanner-app-with-delphi-zxing-and-tframestand/ https://blog.andreamagni.eu/2017/06/scannermapp-a-qrbarcode-scanner-app-with-delphi-zxing-and-tframestand/

How to debug resolver issues in Spring4D? When in constructor occur unregistered type parameter (or registered, but uncompletly - without register his constructor parameters types), Spring creates the object with a bad constructor (without parameters, come from base class), but does not warn about it! And an unfinished object is created, with nil in the key fields. How to avoid this, how to detect it?

ESB Consultancy is please to announce a new release of our huge component and routine library for Embarcadero Delphi - ESBPCS for VCL. This supports Delphi 10.2 Tokyo all the way back to Delphi 7. This latest release is a free upgrade to existing customers - similarly for the subsets: ESBPCS-Lite, ESBPCS-Calcs, ESBPCS-Dates and ESBPCS-Stats. Even if you purchase ESBPCS v1 way back in the late 90's you can still grab this latest update for free! See what ESBPCS for VCL has to offer: http://www.esbconsult.com/esbpcs/ http://www.esbconsult.com/esbpcs/

Hi Everyone. There is no way to instantiate generics at runtime? Eg: TMyGen = class Value: T; Default: T; Min: T; Max: T; end; TMyClass = class // usually.... FMyByte: TMyGen ; FMyWord: TMyGen ; FMyDWord: TMyGen ; // but now I'd like to instatiate the variable FMyValue // as Byte, Word or DWord at runtime FMyValue: TMyGen ; // <-- obviously... compiler error end; how to do that? It's possible? Thanks.

Spring4D - How to get the same instance of Logger for a class group? Everything works on interfaces, but I skip interfaces for simplicity. I have a base class: TBaseClass = class fLogger : TLogger; constructor (aLogger : TLogger); end; Two usable classes are inherited from it: TClassA = class(TBaseClass) fWorkClass1 : TWorkClassA; fWorkClass2 : TWorkClassB; end; TClassB = class(TBaseClass) fWorkClass3 : TWorkClassC; fWorkClass4 : TWorkClassD; end; ...which have working classes: TWorkClassA = class fLogger : TLogger; constructor (aLogger : TLogger); end; TWorkClassB = class fLogger : Tlogger; constructor (aLogger : TLogger); end; TWorkClassC = class fLogger : TLogger; constructor (aLogger : TLogger); end; TWorkClassD = class fLogger : Tlogger; constructor (aLogger : TLogger); end; These objects I use directly in the code: var ObjectA : TClassA; ObjectB : TClassB; ObjectA and ObjectB create their own separate workgroups, and I would like

I am using TJvAppStorage (TJvAppIniFileStorage / TJvAppRegistryStorage) from the JVCL for persisting configuration objects. When exiting a program I use the following code to check if the configuration has changed in order to ask the user whether he wants to save it: function Tfr_Settings.SettingsChanged(out _OldSettings, _NewSettings: string): Boolean; begin _OldSettings := TheAppStorage.AsString; try FOnSaveSettings(TheAppStorage); _NewSettings := TheAppStorage.AsString; Result := (_NewSettings <> _OldSettings); finally TheAppStorage.AsString := _OldSettings; end; where TheAppStorage is a TJvAppIniFileStorage instance. Recently I found that writing to a TJvAppIniFileStorage silently fails if the ini file is readonly. So the code above will always return false even if the configuration has been changed and the user might want to save his changes to a different file. To solve this problem, I could possibly switch temporarily to a different file, but I woul

HGGC which recently lead the recapitalization of IDERA ... ( http://www.hggc.com/portfolio/idera ) ... formerly owned hybris ( http://www.hggc.com/portfolio/hybris ) ... - which they sold to SAP. ( https://www.forbes.com/sites/forrester/2013/06/05/sap-to-acquire-hybris-what-does-it-mean/ ) Do you - being a Delphi developer - think it would be good if HGGC would sell IDERA to SAP?

Does Embarcadero urgently need fresh money?! My Delphi maintenance contract is to expire in September 2017. Already in the middle of May I got an email, telling me that my maintenance contract is about to expire soon (OK, we now have an idea what timeframe is "soon"). I ignored it. Today (end of June) I got a phone call from +1 512.226.8*** on my voice box. I could not understand the name, but the guy says he would like to talk about renewing my Delphi maintenance contract. Here in Germany I've never got phone calls from the US regarding contracts or other sales in the past. Strange. Did they close the EMEA office in germany? Someone here also got those calls?

Spring4d.Container - where to declare what? Let's say I have 2 units: myInterfaces.pas myClasses.pas it is straightforward to have a myRegister.pas which uses those and register the types with the GlobalContainer. Now, if I need a class factory where do I put that declaration? My inclination is to put it with the classes, but that means you would need to place myClasses in the uses clause in the unit that is using the interface - which is not what we want as that binds the application to the class. I have been putting them in myInterfaces.pas - which is fine if the implementations of the interfaces use the same constructor. So what's the mood around this?

I'm using the Spring.Container in some refactoring and am looking for some clarification on the best way (and where - I'll post that separately don't want to confuse things) to set up the factories. I have done this elsewhere, but always where there was a distinct constructor for a type. There is a single interface, let's call it IFileInfoDisplay (because that is what it is called). There are 3 type registrations along the lines of container.RegisterType ('basic'); container.RegisterType ('history'); container.RegisterType ('extended'); Each type takes the same constructor Create(aFileInfo: TFileInfo). TFileInfo is returned from a RemObjects server, hence not an interface. So can I register the factory and call it with the discriminator Container.resolve ('history'); or do I need to register it for each type? Thanks.

New book on the horizon... A little update! I must say that I'm surprised by the level of support I got here! Clearly a $10 discount isn't really a huge incentive for anyone here to preorder my ebook, so I guess most of you really stepped in to offer a helping hand to friend in distress! :) This little - sort of - campaign, will likely fill the gap and cover significant portion of my immediate cashflow needs just in time! Thanks again everyone! :) Oh, I don't have the time to to chat... have to go and write the book, you know ;) If anyone missed my original post - summer and all, here is short recap: I'm writing a book about memory management. The title will be "Delphi memory management for classic and ARC compilers". You can read more about it at: http://sites.fastspring.com/epixeditions/product/delphimm While the regular price will be $37.50, you can still preorder it at only $27.50 (for 3 more days) --- and the complete story https://plus.google.com/u/0/+Da

I'e got an Challenge with SOAP call. (Might be trivial but don't know yet :D ) I need to send request, but I must get to the XML before sending, and then modify it before it's sent to the server so I can sign the actual request. and give extra information which can't be known before the "payload" is done. Is there a way to do it with Delphi SOAP components, or can I make request payload by hand and send that and let the SOAP components use generated interfaces to parse/present the response. Would not like to handle all manually tough... Any thoughts?

What's the easiest way to consume a C++ library in Delphi. In the past I've create a separate C API layer as a DLL that I can call from Delphi. For a large C++ library it is very time consuming to create that additional layer. Wanted to ask if anyone has any ideas before I embark on creating a C API. PS The solution needs to be a mechanism that is crossplatform, so I can't use COM.

Anyone know how to do a dedicated build machine delphi?

I always was of the thinking of maintain every thing in his place. (In Spanish we say "Shoemaker, to your shoes"). Doctor Codd defined in his studies, how the database should be independent in his implementation, of the language used to query or modify his content. His idea is the base of all SQL System. But the enterprises that create and sell the DBMS, legitimately of course, are all the time creating artifacts that made the software "as more dependant as possible of his DBMS". Is because of this, so the language for the stored procedures, triggers and so on, has not an standard. I always run away of this systems that presume of have all the program logic on Database. This is, in my mind, an stupid extreme situation. This is like turning the omelet arround. "The initial idea was make the programming independent of the databases and finally we get the databases independent of the programming language used for the IHM." This ideas are, what makes me be on

Stefan Glienke, do you foresee any real issues one might encounter if he/she use the DI container linked below? The obvious issue would be that it doesn't support interfaces. But in my case I think using class inheritances with abstract methods can overcome that ( https://stackoverflow.com/a/2279242/133516 ) Just in case you might ask - I believe spring4d is excellent, except that the only thing I need is DI so I don't want to rely on such a huge library ;) https://github.com/danieleteti/delphidicontainer

Hi Can you tell me how to Calculate amount from Hours Example i have work 2:30 Per Hour i am getting: 22 USD How to Calculate this in Delphi ?

Hello guys, Is there a way to use object-relational databases in Delphi? I mean those databases which use member functions, member procedures, nested tables, varrays and so on :) Thanks in advance.

I'm using Tokyo here at work to develop our software. The rest of our team is still using XE5. Our build is still in XE5. A QA team member came to me and said one of the calculations (Insurance stuff), is taking 42 seconds. She asked me to try it on my machine. Mine takes 2 seconds. So I compiled the EXE and the DLL (with the calculations) on my machine with Tokyo, and she determined it takes 4 seconds (she's running on a virtual machine). I suspect that there are a lot of optimizations that took place between XE5 and Tokyo, but can anyone quantify this? I'm trying to get them to move to Tokyo.

How do I determine the order of the tests in DUnitX? I've got a few tests and I created separate units for each Test case. Then, I have another unit where I have moved all the TDUnitX.RegisterTextFixtures(xxx) in one procedure. In the main project file, I call the registration method before the runners. But what I get is a kind of random order of the execution of the testcases. Does anyone know how this determined? TIA for any help.

I'm pretty excited about this CData thing. 80+ cloud APIs available through FireDAC without having to deal with the real API? Count me in. Will be interesting to find out how it works. Seems like CData deals with the APIs on their server and provide a translation interface to the data. I use TMS Cloud Pack to access the Facebook API now but expanded SQL access to the Facebook API through FireDAC sounds pretty powerful.

Embarcadero is bombarding me with offers for free stuff like Interbase licenses, free RAD Server licenses, free 2nd Embarcadero product etc. ... but only if I would upgrade from Starter to Pro or from Pro to Enterprise. The problem is, we are already on Enterprise level, for years, with subscription ... those offers are not relevant for me. It's discouraging to receive offers for free stuff that I actually can't get as a loyal Enterprise subscriber. It's almost like Embarcadero want's to encourage me to stop the subscription and go back to our usual 3 to 4 year upgrade cycle.

Is there a way in the editor to move from the interface section declaration of a method to its implementation? And when I ask that, I mean from the declaration signature to the implementation signature, NOT to the implementation begin. We're dealing with legacy code where the distance from the implementation signature to the begin can be many lines. I have not found anything in GExperts, CnPack, or ModelMaker Code Explorer which would accomplish this.

I'm curious as to whether people are using weak interface references in anger? ( http://blog.marcocantu.com/blog/2016-april-weak-unsafe-interface-references.html ) In a nutshell - these were a new language feature for the desktop compilers a couple of releases ago, along with 'unsafe' interface references. The latter (no _AddRef and _Release calls, but you deal with any dangling pointers manually) work like they say on the tin, however weak references (which get automatically nil'ed when the referenced object is destroyed) I'm finding a bit problematic: - The don't work with the Supports function, which remains a key way to actually get an interface reference in the first place. For sure the workaround is easy enough (use Supports against a local field without the [weak] annotation first), but it does involve a further interface type pitfall for the unwary. - Weak interface references break external memory managers. Who really manages to get by without standalon

I have a general design / object question that I'd love to get some different opinions about. BTW, this is a Windows / VCL app in case it matters. I started this project off off with a bunch of related PDF form files that I need to stuff into something to manage them. So far a zip file looks to be the best container. These are form files, and I need to identify all of the fields on the forms and list them out along with some info regarding where the data comes from (some from DB fields, some from the user, some required, some with defaults, etc.). I've got a library to do deal with the PDF stuff; that's not an issue. But I do need to keep some metadata on all of the fields in each form, and I thought an easy way to do that is to put it into an INI file. Easy peasy. However, the more I'm thinking about it, I don't like having a separate PDF and INI. I also don't want to stuff the INI into the PDF (as an attachment). But I can stuff the PDF file into the INI file.

About the support for BoringSSL of the Indy classes are there novelties?

Does anyone know if the WindowState property changed on forms from Berlin to Tokyo? Our main form has WindowState = wsMaximized; at design time. In berlin, the window is maximized when you run the program. In Tokyo, you have to explicity set the WIndowState := wsMaximized in the DPR after the form is autocreated?

I am currently in Chattanooga TN. Looking for local or remote work. Experience in Delphi from D2 - Present. Specialize in point of sale and M2M work, but not limited to this. Experience in developing systems for retail shops, restaurants and gas stations. Use components Firedac, DBGo, Fastreport, Async pro, TMS component pack and more. See my work at www.ultimatesoft.co.za .

I have a question about the usage of packages in a Delphi Application. I've been rebuilding an application of mine, most from the ground up, using interfaces, single class per unit, etc and have started to experiment with package units together. Now the original EXE was circa 6M with Seattle and I know that the RTL BPL is circa 10M in Tokyo. My EXE will get bigger once I start to add more functionality but I'm wondering whether packaging it is worth while (current rebuild is circa 26M with debugging, half of that VCL, RTL BPLs etc). Does anyone have any rules of thumb for the switch point between single EXE to packages?

I have seen that Embarcadero has a new roadmap and I have also seen that there is a discussion about the implementation of firemonkey for linux. Will that happen in the future? I already know about fmxlinux but it's not free. I'd really love to see Delphi 10.X with linux firemonkey (also because the architect licence is very expensive and I don't want to spend even more for a 3rd party component...). Why Delphi tokyo didn't include firemonkey for linux?

I'm running Rad Studio XE7, I have run into a problem. Wonder if you all can help. I have isolated my problem to this example code below, I think it may be a bug. I'm wondering if anybody else can test this in either their copy of XE7 and higher and give me some feedback. I'm using similar constructs all over my code, which was working and for some reason now fails with an access violation. Any thoughts would be great. Code: unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs; type TForm1 = class(TForm) procedure FormCreate(Sender: TObject); private public end; var Form1: TForm1; const ABYTE_DEF = 0; var BytesConst: TBytes = [1, 2, 3, 4]; implementation {$R *.dfm} procedure TForm1.FormCreate(Sender: TObject); var aBytes: TBytes; begin aBytes := BytesConst + [ABYTE_DEF]; end; end. Nothing on the form just hook up the OnCreate to

I'm having fits with D7 under Win 10. The component palette keeps disappearing from the top where it belongs. To fix the problem, I've discovered that I can delete the Toolbars entry in the registry (under Borland\Delphi\7.0). But I'm tired of having to re-do the individual toolbars every time. I'm not sure if it's one of the toolbars that's gotten corrupted or what, but it's pretty damn annoying. Does anybody know of any tools or easy way to edit the Toolbar entries in the registry? They seem to be strings, but they're saved as REG_BINARY entries because they appear to have some binary data saved inline. I have a feeling the problem is simply that the top/left coordinates for one of the toolbars is getting corrupted. (Actually, when I close Delphi then re-open it, ALL of the toolbars seem to get randomly splattered around the top panel with the menu bar on it. I'm not sure if that's happening when the data is saved or later, but the only time I&

StyleControls VCL + VCL Style + TscGPVirtualImageList + High-DPI support! Home: http://www.almdev.com We are glad to introduce our solutions for High-DPI systems (with VCL Styles also). On the screenshots you can see demo with VCL Style, which can be scaled to any scale factor on the fly. All possible VCL Style elements will be scaled automatically. You can move form between monitors with different DPI's. Demo includes several main components: - TscStyleManager component (component to adjust and improve styled menus, styled common dialogs; adjust scale options for style elements and improve High-DPI support for menus, common dialogs, messages). - TscStyledForm component (component to adjust and improve behaviour of styled form) It has OnChangeScale event and you can use it to adjust your controls with AScaleFactor parameter. Also you can add buttons and tabs to the NC area of the form with it. - TscToolPager control with different controls from the package (ribbon analogue control)

How do I use Beep in FMX? According to the documentation, it is meant to be a cross platform procedure but I get the message that it is an inline function and need to use WinApi.Windows. When I do this, I need to use the Beep(freq, dur) form. Anyone knows how I go about using this very sophisticated procedure? Thanks

I've using Firebird in development database applications. Now I my project needs to have a closed/encrypted database (content and structure). I've seen a solution at IBSurgeon but it is much too expensive for me. What solutions do you all use for "closing" the database? Maybe another database system (I've been looking at MongoDB and Postgress)? https://ib-aid.com/en/firebird-encryption-plugin-framework/

Hi, I have encounter some issues trying to import a VCL Delphi 2009 project to Delphi Tokyo 10.2, Works fine in Delphi XE6. 1. It won't create a win32 or Win64 folder neither the corresponding Release or Debug sub directories. 2. It won't compile the project to the project folder unless I specify the output folder manually in the project options. This is done automatically in new projects. 3. Can not create self-signed certificate. It happens only with this old project new projects seems to be fine.

Hello, Do you know how to setup a 3D Isometric view in Firemonkey ? Eugene Kryukov perhaps ? ;) something like that http://www.execute.fr/isomap3.htm

Can I use TPrototypeBindSource once I set it up to work with ContactName, i.e, and get the values? Something simple like: while not PrototypeBindSource1.Eof do begin Label1.Text := PrototypeBindSource1.... <-- How to? PrototypeBindSource1.Next; end;

Hello all! In a try to create an Android application with FMX , I noticed that opendialog does not respond. So after a research on the internet I used the code from this link: http://bluexmas.tistory.com/427 . Now I want to load the text from the selected file to a TMemo but it does nothing! I believe that the conflicts i related with the way that I select the file because when I run this with TOpenDialog in Windows it runs successfully. Any ideas?

Previously i have not been big on IDE plugins. So i'm blatantly asking for pointers on the following, i.e. is there already such beasts? Or maybe i'm ignorant of a new/old IDE setting. Crtl+C - create implementations in the same order as the interface section ? Ctrl+C - adjust the signature of the method the cursor is on interface if implementation and vice versa. I realise they can both be very tricky to implement. Second function might not be able to handle overloads.

Real PNG support is still not here not even in Tokyo so I still continue use PNGComponents. Uwe Raabe every time I upgrade this components I have to apply my little changes (small ones) to TPngBitBtn and TPngSpeedButton. Where I could send you my changes to evaluate if they could be inserted in the original sources? Thank you

Wow. Now all components and modules updated from 10.1 Berlin to 10.2 Tokyo. All our win32 and android projects are compiling fine > thanks to Stéphane Wierzbicki for updating androidapi.handheld unit! Only one thing i can't get working is, when i try to update an already installed application on android with the new one (compiled now with 10.2, before 10.1) it says that something is not correct with app-signature so the update can't be installed. Should our android app not have same signature in 10.1 and 10.2? I'm missing something?

QC now forwards to QP and it is no longer possible to see your older open QC posts. Since the RAD Studio IDE still appear to report issues to QC - how can we now keep track of our submitted issues? When will the internal error reporting in RAD Studio file reports to QP instead of QC?
