How to unload app from memory when closing the app. After confirming that the user wants to exit the app, I call "close". The app remains in memory as shown in the list of recent apps. I can then switch to it and it is in the same state as it was when it closed. Application. Terminate does the same thing. I want my app to completely unload. Can someone tell me how to do this? Delphi CE, Android SDK 25.2.5 Thanks...Dan'l.

how to add data packet to data set in VCL form. In a sample code I see persistdatapacket binary value for TClientdataset : PersistDataPacket.Data = { BF0000009619E0BD010000001800000006000000000003000000BF000743455F......} how to add them, my dataset is used to manually populate data in the code, no data provider in VCL form. The dataset is to used in a data grid, when trying set field, get error: clientdataset missing dataprovider or data packet. Thanks.

I’ve just read Sarina’s post about the Beta 10.3 programme having started and I have an active Update Subscription but haven’t had an invite email yet. I really want to help test the beta so keen to get access. Sarina mentions contacting my sales rep if I’ve not had the email but I bought through a U.K. third party so not sure if that’s the correct route. Has anyone else had to do this and if so, how did you request an invite? Is there a specific email address or link to contact the correct team?

I'm having an issue in converting HEX to a string. Here's the routine I use: function HexStrToStr(const HexStr: string): string; var tmp: AnsiString; begin SetLength(tmp, Length(HexStr) div 2); HexToBin(PWideChar(HexStr), @tmp[1], Length(tmp)); result := tmp; end; For the most part this has done me well over the years but at the moment I am exchanging values with a third party and finding some characters don't translate the same way. So, for example: HEX 82 converts to character 8218 in Delphi (single low-9 quotation mark - "‚" ) but in RapidTables and CodeBeautify it converts to character 130 which is what 82 is equal to (a non visible character btw). HEX 97 converts to character 8212 ("—"). Any ideas? https://www.rapidtables.com/convert/number/hex-to-ascii.html

I wrote a function to make JSON more readable, and naturally I wonder if I missed something crucial so that it eventually will break?

Synchronized ListBoxes I have created a test app that has 2 ListBoxes where the ListBoxItems move with each other. It works but has an oddity. If the right side ListBoxItem (lbi) is out of view when the corresponding left side lbi is selected then the right side lbi move into view at the top or bottom of the right side box, but not aligned with the left side lbi. I can work with this in my app but is not user-friendly. Does anyone have any suggestions on avoiding an offset?

Did anyone get the latest FacebookSDK running on iOS? I get "Undefined symbols for architecture arm64: Error: "___isOSVersionAtLeast", referenced from: -[FBSDKApplicationDelegate..." Facebook sent me a warning that I use a deprecated version of their Graph API, so I downloaded latest Facebook API (v4.36) and merged it in with my iOS11.2 SDK (used because Delphi fails in static linking with iOS11.3 and newer). I assumed that the above error was because the FBSDK is made for a newer version of iOS, but I don't see any requirements about that on the FB SDK pages, so what can the problem be?

https://stackoverflow.com/questions/52483218/delphi-code-completion-fail-with-anonymous-methods I have seen this question and I am curious. There is an answer that has been accepted and in fact it solves the problem but I still have the doubt. Is the code valid? I have taken Object Pascal Handbook (the latest edition) from my shelf and I've seen that Marco Cantu in his code, in the exception handling part, uses a try-except in the inner part and then a try-finally surrounds the try-except because it protects the Object.Free. Is there a reference somewhere about this? Or is that simply a bug? I have always used a try-except inside a try-finally and never a try-finally inside a try-except https://stackoverflow.com/questions/52483218/delphi-code-completion-fail-with-anonymous-methods

Any ideas where I can get version 10.1.1.37 of PA Server for Mac OSX and Linux?

I was wondering if this could be done. In the debugger, when I'm inspecting a variable (an array of bytes), that represent a string -- but at debug time, I just see the byte array elements as the ansi character number of each element. We have a function "AnsiCharArrayToString" that will convert this array of bytes to a string. Is there a way to somehow create a debugger construct to convert this byte array to a string in debugger insight? If I allow side effects and function calls when inspecting, I can get it to show the string, but I was wondering if there is an easier way..

This is a question that probably Marco can answer but I figure it's a good question to ask publicly - my company currently doesn't use Delphi. We have a company-wide Hackaton next month, which means we get to propose whatever we'd like to see implemented in our company. I'd like to propose an app and I'd love to make it with Delphi; I need a fully working multidevice mobile app to be made in less than a week, and I think Delphi is pretty much the only good option for that. Can we use a trial license for this competition? (it's just a week). Do trial versions have limitations in the creation of mobile apps?

Assuming you would like to build something like in the Delphi project options Compiler settings where you have a base configuration (All Platforms) and then you have a bunch of derived configurations (Android, iOS etc.) that can override the settings from the base configuration. What data structure would you use for that. And how would you implement persistence of such data?

Since I put up 10.2, I cannot get a form width >1620. Whenever I enter a greater value, the system changes it back! As I have some programmes with complex forms about 1800 wide, can anyone please tell me how to get a decent width back please?

I managed to compile AnyDAC and even got my old application compiling in Tokyo, but AnyDAC fails to get data.

Is there a way to use the JVCL's TJvXxxAppStorage to store float values as strings (e.g. "10.152") rather than hex dumps and also control the decimal separator that is being used? I know that I can set AppStorage.StorageOptions.FloatAsString := True; But then it will use the currently active DecimalSeparator when I store a float property, e.g. "10,152" for standard German settings. It internally calls procedure TJvCustomAppStorage.WriteFloatInt(const Path: string; Value: Extended); begin if StorageOptions.FloatAsString then DoWriteString(Path, EncryptPropertyValue(FloatToStr(Value))) else DoWriteFloat(Path, Value); end; Which calls FloatToStr which uses the DecimalSeparator. Providing an OnEncryptPropertyValue handler won't solve that problem either because then the result will be mime encoded. (I think it cannot be done without changing the WriteFloatInt code. But I would like a confirmation for that.)

I have hit a big snag with DevExpress ribbon recently. Its a long story in a (so far) private ticket at DX. It's really slow going and i'm not getting all sides of the problem. What i mean by that is a ticket is a ticket so they are trying to solve the same specific problem. But i'm not getting really far when trying to discuss alternate solutions to my problem. When googling on DevExpress + something all their other flavours come up a lot. So i was thinking, would there be any interest in creating a G+ group called "Delphi DevExpress Users"? To discuss design issues using DX VCL? If i get a positive response here, i'll go and see how to create such a group. Regards, /Dany

These is a cool project by one of my fellow Chinese Delphi programmers called nickemma (see original links at the end of the post) I came across today that I couldn't resist to share with the world: Picture 1 === The electronic car that receives control commands through WIFI, sent from an Android app developed in Delphi. Picture 2 === The FireMonkey app that sends hex. control commands to the toy car.BTW, it uses an UI framework called OrangeUI that's available in China only. Picture 3 === The settings window of the Android app where you specify the IP of the toy car's WIFI modue, the hex. commands for turning left/right, forward and back, and so on. Picture 4/5 === He made two toy cars each of which are differently constructed, but seems to be controlled by the same Delphi-powered Android app. I don't know much about the electronic thing, but this project obviously shows a cool part of Delphi :) link1: http://bbs.2ccc.com/topic.asp?topicid=552684 link2: http://bbs.2ccc

Hello, Below is reproduced on both Delphi 10.2.3 and Delphi 10.2.2. I expect code to display 1715. I do read 1715 (no decimals) after multiplication on Debug. After Trunc() value is 1714. I know Trunc() rounds towards zero. It is just there is nothing to round as decimal here. var ADouble: Double; AInteger: Integer; begin ADouble := 17.15; ADouble := ADouble * 100; AInteger := Trunc(ADouble); ShowMessage(AInteger.ToString()); end; Thanks.

Having started with Delphi before the Cardinal type was available (Or has it always? I can't remember.) I routinely declare 32 bit unsigned variables as LongWord. What do you use?

Spring Collections I have a list of elements, there are, for example, 100 of them. List : IList ; I want to get 5 values greater than 10 and I do it like this: result: = List.Where(ValueIsGreatThan10).Take(5); Will the "work loop" be executed a minimum number of times and if, for example, the first 5 values in the list will be greater than 5, then only the five will be checked? Or maybe the Where() loop will scan 100 elements, and Take() will return the first 5 results?

https://plus.google.com/+YaroslavBrovin/posts/JnveEy527YN This is a project that I am SURE will replace FMX because (if it works well as I expect) we will have native android and iOS apps. Yaroslav Brovin when will you release this? Any other updates?? I see on the telegram group that you put screenshot of 100% native android apps created with Delphi but they are 3 months old. Updates?

I need some help with Livebindings. I have a TLabel component linked with a TIntegerField. Currently, I have the next CustomFormat property: %s+"%%" and it works well. Shows the number of the field with a percentage sign at the end. What I need is an expression that shows the same but if the value is 0 (zero) show "---" instead of the value. I've tried things like IfThen(%s = 0, "---", %s + "%%") or IfThen(ToStr(%s) = "0", "---", %s + "%%") but I always get "No argument for format..." error. I think is because I use two %s. But how I do this then? Thanks in advance.

If I were to choose the best program MS ever written, I'd choose MS Paint. Not Paint 3D or else, the original MS Paint as in Windows 7. If you need to draw a raster picture with several shapes, arrows, captions, etc, MS Paint is perfect. There is nothing even close to MS Paint in the Linux world, only buggy and low-functional software claiming itself MS Paint clones or replacements. I understand now why some recommend to use GIMP for drawing on Linux, though GIMP is a heavyweight not designed for easy drawing.

Fellow Delphi Developers! Just tested VCL Styles from delphistyles.com with StyleControls VCL 4.0 from our partner www.almdev.com ! We have awesome results! You can really jump to a new UI level in applications!

Our main delphi VCL application has a number of plugins (all written in delphi) as DLL's. Within the DLL's we want to have VCL forms that get requested to be shown by the main app. This always worked well for us when the forms were shown modal; but now I am switching some forms to be non-modal. I pass the TApplication handle of the main app into the DLL and assign it to VCL.Forms.Application inside the DLL. This seemed to resolve most peculiarities (like the form disappearing and not reappearing after minimizing), but the one thing that still seems wrong is the form from the DLL is always on top of the main application form (it's not set to stay on top). Am I doing something I just shouldn't be doing, or should this work fine?

Has something changed with WifiInfo: JWifiInfo in Tokyo 10.2.3 which is not public? We're porting now our app from Berlin to 10.2.3 and we're using jWifiInfo to getMacAddress of Android devices. Same app on same device compiled with Berlin is getting correct mac, app compiled with tokyo 10.2.3 is getting 02:00:00:00:00:00 as result. All access-rights should be set.

Hello, This will be my first post/question :-) I have a large VCL application made up of several EXE's and 100+ dynamically loaded DLL's with forms. The primary EXE has a Datasnap client inside it that calls methods of a service running on a server for concurrent user tracking, so we know who is logged into the software. Today I implemented a Datasnap callback so a message can be sent through the Datasnap channel from a monitoring EXE to all connected clients. The message trigger on the client side then issues a thread sync call to a procedure in the main GUI thread that calls "Close;" to end the program. This is working like I expected it to, it calls Close and the EXE ends as normal....until a form from a DLL is in use. The DLL is calling Application.Terminate, which destroys all the created forms in the DLL and exists the DLL and frees the resources, but then it stops at the EXE in the method where the DLL was loaded from, like the user just close the form norm

I am studying the so called "C# bible" (the book is C#7 in a nutshell) and I see that A LOT of things that there are in delphi are also in C#. Like the File class has identical methods, same for the stream classes names (and the hierarchy), datetime libraries, stopwatch and so on. Well I find C# super powerful, so would it make sense if Delphi had: - something like "auto" in C++ and "var" in C# (now java has "var" too). I find it very useful! It deduces automatically the type like "auto i = 5" or "var i = 5" gives the same result as "int i = 5" - the += operator and the -= operator - the possibility to have something like this: https://pastebin.com/WRi0hd3Q I do not want to make Delphi a C# with a different syntax but I just think that these would be nice features! Delphi has copied a lot from C# so it could copy these nice features as well! I do not know technical details but could these be implemented? https://p

I think that time ago I read in this group that the Professional Subscription of Delphi now includes de Mobile AddOn. Is this correct?

Is there a checklist online to debug autocompletion, errorinsight, or perhaps some tools to help the issue? It stopped working on my delphi Berlin project and I cannot seem to get it working. Perhaps I'm missing some toggles. I (think) it stopped working when I added a number of var x: TypeX; y: TypeQ absolute X; references, the Bidit compiler really seems to hate these, I am loath to remove them though, I really like the way `absolute` fixes illegal typecast errors. I'm doing lowlevel bit-twiddling BTW. Obviously there are no errors or warnings in the compilation of code. With DelphiAST so advanced these days I'm half temped to write my own error insight, code completion implementation.

Fellow Delphi Developers! We are glad to announce that StyleControls VCL v.4.0 just released! Key features: - Unique solution to create UWP-like applications (you can fully customize form, enable DWM shadow with hit test for it) - Excellent support of system Themes and VCL Styles - Improves VCL Styles on Forms, Menus and Common Dialogs (and for High-DPI systems) - All controls work fine, faster, without any flickers, have the same functionality with system Themes or with VCL Styles - All controls have support of High-DPI systems with any DPI (no limitations and with VCL Styles) - Complex solution to scale images in controls on High-DPI systems (icons, backgrounds and many more) - A lot of advanced controls to create really modern application - A lot of controls has multi-theme (style) adjustments (for example, one button can looks and works as push button, tool button, spin button and many more) - Additional collection of controls, which use GDI+ (edits, memos with transpar

Hi all, Is there any way to know which Style has been applied to a FMX StyleBook? If you look at the FMX, it's hard coded in a huge hex string. But I have a style in one of my apps that I like, and don't remember which one was applied. Opening the StyleBook doesn't mention which style file has been loaded. Any other way to know whether I applied A.style or B.style? Thanks for any help Steve

I'm trying to build this library in Delphi 10.2.3 Tokyo: https://github.com/pjde/delphi-mqtt (I have the latest ICS lib installed as well.) It looks like the author used Delphi XE to build this lib originally. I opened the .dproj file in Tokyo and it prompts me to convert it. I took the default. Then I went into project options and set up the folders for debug on W32 and W64, then I ran Build. When I got it to finally build ok, it complained that it had to implicitly import a bunch of ICS files. The original Requires file spec has a bad path on it, and is also for the wrong version of Delphi. Anyway, the problem I'm having is that after running Build, there's no Install option present in the right-click menu. So when I try to open the demo file, it complains b/c it can't find the components anywhere, which is to be expected. It doesn't look like the author properly separated things for Design and Run-time needs, but there IS a register proc contained in uMQTTComps.

Wrapping up the Tweening animation library for VCL, so that is ready to ship to patrons after work tomorrow. Next on our list is PixelRage! Been wanting to finish this for quite some time. It supports 8-32 BPP, layers, fast pixel conversion used on blitter level (so you can copy a pixmap to another using alpha blending, color key - and it will convert the pixel data ad-hoc. If you draw a 32 bit pixmap onto an 8 bit image, it will try to map the colors (and it does a great job). But coolest is probably the full paint program! It reminds me a bit about Paint Shop Pro if anyone remembers that? You can do pixel art, but also have high level brush functionality etc. #Embarcadero #Delphi #Patreon #VCL https://www.patreon.com/posts/pixelrage-21312723

What is the text of those lines the IDE automatically inserts into new form etc. declarations in the localized Delphi versions? In English they are: { Private declarations } { Protected declarations } { Public declarations } { Published declarations } As far as I know there are German, French and Japanese localizations. What's the text there? And please make sure you get the case right.

I did some measurements with new direct PDF export (using SynPDF) in HTML Library. * Document parsing and print preview generation (135 Kb): 94ms (414 pages/sec) * PDF export: 20ms (2000 pages/sec). Previous version use intermediate metafile object, so export was slower and images was reencoded. Now all images are saved in original format.

We need to implement reminders in something, modeled after what Outlook offers. There's a checkbox to enable/disable a reminder; a calendar to pick a date; and a combo-box that has 48 entries on 30-min time boundaries, from 00:30 to 23:30. This data is being stored in a DB record. This is running in Windows. Is there a solution other than polling the DB (running a SQL query) every 30 minutes? So if you want to get an alert next Wed at 4:30 PM, what can be done without polling the DB every 30 minutes? EDIT: is it possible to use Windows Task Scheduler to help? Say, poll the DB every 24 hours and pull down the reminders scheduled for the next 24-hr period and then poke them into the task scheduler. All we need is to get a windows message with a couple of parameters sent at the assigned time. Note that this app is a regular app, not a service. We don't need to start/stop any services or even apps, just send a message. (I'm not familiar with the Windows Task Mgr API, so any ins

Does anyone know of a way to stop a FireMonkey scroll box from scrolling during dragging? I have a control inside of a TVertScrollBox which I need to handle the mouse/finger events rather than its parent scrollbox. Everything I’ve tried hasn’t worked and the control moves around in the scrollbox while interacting with it which is really annoying UX. I guess I need to stop the events propagating to the parent once handled but can’t see a way to do this. Has anyone managed to do this? Thanks!

Well, we have been waiting to long, after the closure of the forums.embarcadero.com , which fortunately currently can still be read, but cannot posted on anymore. So I have decided to design a replacement Forum, which is based on the same layout as the original forums.embarcadero.com : " http://www.delphiforum.net " This Forum will STAY. It will not be removed, and when I drop dead, it will become available in the public domain. The Forum runs on a Linux Debian based VPS with a MariaDB (MySQL) back-end, located at a major site in the Netherlands. Right now, it look rather empty. So please SPREAD THE WORD any way you can think of, so that all previous Embarcadero forum users can now migrate to this compatible forum. Any requests for changes and improvements, please email me at delphiforum@sartrack.nz PS: Note the correct URL for this Forum: http://www.delphiforum.net and NOT delphiforum[s].net which is a locked, non-existent domain stolen by GoDaddy to make money out of it.

Hi guys, I just want to share my experience with Tokyo 10.2.3 and HDPI. To test HDPI I'm running Delphi on Win10 (latest version) on a machine with 2 monitors: - main monitor a 27" HDPI 3840x2160 200% zoom - secondary monitor 24" Full HD 1920x1080 100% zoom The secondary monitory is positioned on left (as shown on attached picture). On the monitor 2 I'm running the Delphi IDE (cause it's not ready for hdpi) and on monitor 1 I run and debug the application to test VCL hdpi. Some considerations on my situation: 1. I get often IDE access violations: analizing IDE call stack I could see that are involved always TMonitor objects in theese errors so I suppose that this kind of configuration is not really tested and used. 2. Ide popupmenus positions are calculated in wrong way. I suppose IDE works with main monitor resolution and not with resolution of the monitor in which is running so in my configuration several menu items are sometimes not visible depending on where

Sorry Embarcadero you are great with WINDOW but on Android.. I Started investigation ,for a project, a piece of code for Android just a few lines of code <50. On window it runs great, but On Android waaa.. bad bad. 1. The size 40G i can not run it on S2 (luck of memory) only on S6. 2. Behavior bad. 3. How do you Ebaracdero expect a professional user to work ? 4. Do i research on each pies of code ? wast of time. same exact project with Android Studio 1. The size 780k!! 2. run as expected. I love Delphi and its IDE using it since #1 but it seem i will not use it for Android. I mite be wrong ,i will keep trying. P.S I made all ready a project for Android with Delphi and it works Ok but once started on a new one well... cannot go beyond investigation. To sum it up Delphi is much better , then Android Studio , for designing a project but it lucks the 100% result.
