A couple days ago I started receiving spam emails from "The Delphi Parser" product. I never used it, or interacted with it or anything related to ti. To the best of my knowledge, that comes either from here, or from linkedin (most likely). But just to rule out this source of email leaking for sure: anybody else experiencing this? Thanks.

Can't get anything from a TLocationSensor in VCL. I've used Delphi 10 Seattle to build the sample project for VCL Sensors in Documents\Embarcadero\Studio\17.0\Samples\Object Pascal\VCL\Sensors Testing in Windows 10 on both, a Microsoft Surface Pro and a Microsoft Surface Pro 2, the sample application runs mostly as expected, displaying and updating information from the following sensors: msAccelerometr: TMotionSensor; osCompass: TOrientationSensor; osInclinometer: TOrientationSensor; However, the sample application displays no information from its location sensor lsLocation: TLocationSensor; On both of these machines, running the Windows 10 Map application indeed shows the correct location, so I'm confident that the location service is enabled and working properly. I just can't seem to get access to a TLocationSensor from a VCL application. Any ideas how to get this to work?

I love the new Clipboard feature in Delphi 10 Seattle. Since the Find in the editor is now NOT a modal window, the multi-clipboard is useful. However the Replace dialog is Modal, so the multi clipboard is useless. Barring them making the Replace dialog NOT modal, is there a way to use the multi clipboard with Replace? (Forget about the GExperts grep search - that's totally modal)..

Smart Mobile Studio 2.2 Release Candidate 2 is here! http://smartmobilestudio.com/2016/03/30/smart-mobile-studio-2-2-release-candidate-2/

I am chasing a problem with an XE7 app which throws an "Invalid pointer operation" error. The difficulty is, this occurs only when the app is built on our build machine, and not in the development environment. We use EurekaLog, but the error does not result in an ELF file being produced.  I am nearly at my wit's end trying to imagine a method for locating the cause. Since we cannot reproduce in the development environment, we cannot find it in debug.  I have checked the build options in use on our build machine against those in our development environment, and found no difference. Suggestions?

Anyone has a clue that there is somewhere a wrapper so it is easy to remove and append items from a TArray . Shouldn't this be basic functionality ? Or am I missing something.

Delphi x64 (Seattle) seems to ignore alignment directives.  I'm pretty sure someone has already asked a question about this, but I can't find it due to lack of google foo..

Has anybody ever tried to replace the DOS executable stub, that prints "This program requires Microsoft Windows" with something more fun? Can this be done with a Delphi program (where the DOS program is maybe written with Borland Pascal?)?

Safe event hooking for Delphi IDE plugins revisited A while ago I blogged about Safe event hooking for Delphi IDE plugins. I have used this method in GExperts as well as my Delphi IDE Explorer and it worked fine for both plugins. Today I looked at the code again and didn’t like it very much. Yes, it works fine and there aren’t any apparent bugs, but it blatantly violates the DRY (don’t repeat yourself) principle. Back, when I wrote it, my goal was to get something working fast so I could use it for my main goal: Make GExperts and the IDE explorer coexist peacefully within the same Delphi instance, even though they both hook Screen.OnFormChange and Screen.OnControlChange. Today, my goal changed. It’s now: Improve the code. http://blog.dummzeuch.de/2016/03/28/safe-event-hooking-for-delphi-ide-plugins-revisited/

BaseNcodingDelphi is a rewritten version of DelphiBaseNcoding (Now Deprecated) with a more "Object Oriented View" in mind. BaseNcodingDelphi is a Library for encoding of binary data into strings using base32, base85, base128 and other algorithms. https://github.com/Xor-el/BaseNcodingDelphi https://github.com/Xor-el/BaseNcodingDelphi

Here is a Library I ported that makes byte size representation in code easier. TByteSize is a utility "record" that makes byte size representation in code easier by removing ambiguity of the value being represented. TByteSize is to bytes what System.TimeSpan.TTimeSpan is to time. https://github.com/Xor-el/ByteSizeLibPascal https://github.com/Xor-el/ByteSizeLibPascal

Hello all, Been pretty busy with school stuffs so have not really had time to code. Had some free time recently and decided to make good use of it. I made some improvements to some of my open source libraries. here is a summary of them. 1.  xxHashPascal I made two variants of the library, one with reference counting and the other without. I also made the library compatible with Free Pascal. Added Unit Tests. https://github.com/Xor-el/xxHashPascal 2.  EmailValidationPascal I also made two variants of this library, one using Zero- Based String Index for Mobile compilers and the other using the regular one based Index. I also made the library compatible with Free Pascal. Added Unit Tests. https://github.com/Xor-el/EmailValidationPascal https://github.com/Xor-el?tab=repositories

Does anybody know how the "Extract Interface" refactoring works? I click on it and nothing happens :) A

Hi I have decided, finally, to try out interfaces. I read about it for few weeks and today I was ready to start coding. Well, I got stuck pretty fast. I was planning to replace a base class - derived class technique with an interface. The problem I have is it seems that when the interface is implemented thru a TComponent, you need to implement yourself the TInterfacedObject and prevent the reference counting in few area. Is it what I need to do or am I missing something. It seems so easy to do it with TInterfacedObject but not as easy if you still what it to be a component. What is the right way to implement an interface with a component? Is it to create 2 classed, one from TComponent only and one from TInterfacedObject? and then the component creates the interface? Any examples would be great. Thank you Marco

I want to store some passwords in a database. I encrypt the password using a simple xor encryption. As soon as I save the encrypted password to the database the password is truncated at, as it seems to me, random length. Using plain text files everything works just fine, no truncation. Am I missing something obvious here? I don't need any fancy encryption routine, the passwords are not very sensitive :) Any links/tips would be appreciated.

Originally shared by Gnostice.com Gnostice PDFtoolkit VCL updated - rendering Type3 fonts and patterns We are happy to announce the release of PDFtoolkit VCL 5.0.0.266. In this release, we have introduced support for rendering Type3 fonts and tiling graphics patterns, and applying multiple digital signatures on a PDF. It also include several other enhancements and fixes. We also introduced a really cute feature for printing: Print current view. This is an API on the PDFViewer where you can zoom into the area you want to print and then call the PrintCurrentView method. This will print only the visible region of the page or several pages (whatever is visible) in vector format. You can select multiple pages and get them to print on a single sheet of paper on the printer. The new printer demo shows this new capability. We continue the work of implementing complete support for the PDF specification and enhancing the product to enable you to get things done with PDF documents. For more info...

Hello! I need some help identifying the best way to generate licenses for a system of applications I am doing. There won't be any trials for these, so basically there should be two types of license: rent and purchase. Rent is meant for re-sellers whereas purchase is meant to be done from me. Before you go on a rant that there is no trial version, please be aware that every user, 100% of the time, with NO EXCEPTION will have been exposed to those they want for some time before doing the purchase, so they will know quite well what their capabilities are and will have interacted with them.  I was thinking to use some form of UIID, but I am open to suggestions.

Problem was I had a number of test cases with the same name.DunitX still rand them, but TestInsight only ran the last one. Obviously my fault as I should really have named all the tests properly, but even so  it would have been better if TestInsight either ran the test anyway - or flagged up an error.

Hi Colleagues, We've just released another beta, which supports Android native UI design for Delphi projects (as it does for iOS/Mac OS).  If someone feels "true-native" not only look, but behavior does matter when using Delphi for mobile development, we'd be glad to present TurboCocoa. Comments/critisizm are highly appreciated! Let's make Delphi build absolutely UX-authentic mobile apps: this time for Android. http://www.turbococoa.com/

Hey everyone, has someone used the Inclinometer3D sensor on Android 6.0+ and Delphi Seattle? I've got the Nexus 5X and when executing the official gyroscope demo the rectangle is going totally crazy. It seems to me, there is a bug inside the Delphi implementation of android sensors. I took a look at older source code from XE7 (in my DX trial it's not available): But when accessing the TiltX, TiltY, TiltZ values there, every time the sensor event queue is requested. Keeping in mind that the device is still moving, while getting TiltX, TiltY and TiltZ, those values may come from different sensor events. So they can not be consistent anymore. Besides that I had to compile the gyroscope demo with sdk 24.4.1 and ndk 10e. Another problem seems to be the UpdateInterval, which is on Android 6.0+ at least 18019 microseconds. Values less than will lead to freaky data again. The last problem I've detected, is that the Rotation Vector Sensor (= Inclinometer3D) still got some gyro drift...

Threads and UI I have a feeling that sometimes, something, somewhere is trying to UI things from a non-UI thread. Naturally, this is something we strive to avoid - but with all the injection of handlers - and literally hundreds of places where someone could think "surely, it would be clever to update that status label now" - it is a bit of a grunt task to review all the code. So, before embarking on such a review quest, my question is: Which symptoms could arise from touching UI from a non UI thread? AV? Deadlocks? Temporary freezes? Donald Trump? I am seeing temporary freezes (20+ seconds) in the UI. The background threads are all looking active, doing and logging their stuff. My first thought was a lock contention - but I log all locks that fail - and the log shows nothing of the sort, so I am in a bit of a pickle here.

Published the third part of this serie about the use of MVC with Delphi. We present now our ORM classes generator. This piece of code is going to be very important in our project, but it can be used as a separate piece of code in a lot of circumstances. Included the first battery of Unit Tests. Remembering us what is our objective of implementing MVC in our project: "Construct code without errors that demonstrates itself that all the functionalities have been proven and then protects these functionalities over the changes made over time" https://sencille.wordpress.com/2016/03/21/3-sencille-mvc-orm-generator-tests/ https://sencille.wordpress.com/2016/03/21/3-sencille-mvc-orm-generator-tests/

Help, sin and cos  como hacer un aplicacion en delphi que muestre, seno, coseno , tangente y sus inversas?.

Hello!  I have come across a situation where I think that mixing objects and interfaces is necessary and not dangerous. Here is my current situation: I have a unit where I have IService declared in the interface section and TService declared in the implementation. IService implements two methods: NewCommand and NewLocalCommand. Both return the same ICommand interface. The essential distinction between them is that a local command is generally visual and bound to the client software, whereas a non-local command, instead, corresponds to a remote call. They are generally used for different purposes but they are both commands, so it is right and proper that they would get the same interface. Now, the problem is that I do want a distinction in the implementation, so I have split base classes both referring to a common ancestor and I have two separate registers made up of different enumerations associated to the correct base class types.  So, I need to add commands to these registers, so I a...

TPriorityQueue for Delphi? Does anyone know of an efficient implementation of a Priority Queue for Delphi (ideally using generics)? There seems to be a couple of old libraries (e.g. SysTools and EZDSL), which I don't think use Generics and I'm not confident will be kept up to date. What I'd like is a TPriorityQueue which has a comparator and takes care of keeping the queue in order. I'm a little surprise System.Generics.Collections doesn't have it - Steve

Is this what you aspect from debugger? (#D10Seattle) Debug this code following execution step by step: var   L : TDictionary ;   I : Int64;   S : String; begin   L:=TDictionary .Create;   try     L.AddOrSetValue(1,'aaaaa');     S:='';     for I in L.Keys do         S:=S+L.Items[I];  //   finally     L.Free;   end; It seems that the higlighted line is executed two times but its not. I suppose that the second time is related to the end of the for loop but this is a little bit misleading.

I'm having a problem with my build machine since I have moved to Delphi 10 Seattle. The build machine is producing different results to the IDE despite using MSBuild on the build machine and setting the correct configuration. It does the same thing on my machine, so it's not related to something on the machine. The differences I can see so far are: 1) Executable size is different. 39MB command line MSBuild, 35MB IDE build. 2) I get an integer overflow error in the executable produced from the command line whereas this doesn't happen from the executable in the IDE. They are clearly two different executables. 3) A COM DLL when built in the IDE is 22mb whereas it is around 59mb when built on the command line. A little further investigation shows that it is actually adding debug information into the DLL DESPITE debug information being off in the release configuration. If I set the "put debug info in a separate TDS file, I then get the same 22mb file plus a 36mb TDS file. T...

New experimental FastMM version was committed to https://github.com/gabr42/FastMM4/tree/Locking_Improvements . New in this version: - Slightly simplified code in FastFreeMem path for small blocks. - Added debugging function LogReleaseStackUsage (has to be enabled by defining DebugReleaseStack). - Replaced GetStackSlot with a better-hashing version (turned out to make a difference in the field). - Added a low priority release stack cleanup thread (frees memory that could get "stuck" in release stacks when a thread exits). All changes were also merged into https://github.com/pleriche/FastMM4/tree/Locking_Improvements . Please test & report! https://github.com/gabr42/FastMM4/tree/Locking_Improvements

A. Bouchez Can you help me? This encryption thing is kicking my ass, mostly on the C# side. Here are my Delphi algorithms for encoding and decoding using AES: EncryptFunc := function(const aPassword: String; aClearText: string): string begin Result := TAESCBC.SimpleEncrypt(aClearText, aPassword, True, True); end; DecryptFunc := function(const aPassword: string; aClearText: string): string begin Result := TAESCBC.SimpleEncrypt(aClearText, aPassword, False, True); end; end; These work marvelously on Delphi with Base64 encoding on the way in and on the way out. But C# -- not so much luck. Can you provide any guidance at all on how to decrypt things on the C# side? Any help at all would be appreciated very much.

Given the recent problems with Embarcdero.com's website, have you disabled the Welcome Page within your Delphi IDE?  See: http://wiert.me/2016/03/14/delphi-disable-or-change-your-welcome-page-to-not-use-the-embarcadero-site-as-that-site-has-been-hacked-twice-this-weekend/

Has anyone experience with Honeywell Dolphin Black 75e devices ? Specially with the laser barcode reader ? I plan to purchase this device.

Anyone else think that Embarcadero should migrate EDN to something that actually functions reasonably? Like any CMS ever? The current site seems to be some custom ASP/.NET solution. It is really quite odd.

Guys, can anybody reproduce this error on Win7, Win8?

If you are using CustomizedPreview you MAY provide your own event handlers. And you may use standard ones 2. Standard drawing uses function TCustomForm.GetFormImage for work 3. That's exactly how demo works: https://sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches/RADStudio_Seattle/Object%20Pascal/VCL/Taskbar/MDI/ 4. I've noticed even some more weird behavior inside TTaskbar.DoWindowPreviewRequest. There is a call to TTaskbar.GenerateFormImage with default height and width (0, 0) and of course it won't draw itself in this case. 5. I tried to change "High-DPI support" and "Use Windows theme" options without success.

I have been tasked with finding and choosing an encryption library for Delphi. One of the main criteria is that it work with C#/.Net -- i.e., that something encrypted with Delphi be decrypt-able with C#/.Net, and vice versa. I've also been tasked with, once the library is chosen, selecting an encryption algorithm. Again, it needs to work seamlessly with C#/.Net Leadership seems inclined to use Turbopower's LockBox, but then this brings the question of Version 2 versus Version 3. I confess to only limited knowledge of encryption, and so am asking for the wisdom of you fine people to help me. Any advice on where to get started? Any advice on various Delphi libraries that should be C#/.Net friendly? Your assistance in this matter is greatly appreciated.
