[New feature request - Static array declaration improvement] https://quality.embarcadero.com/browse/RSP-16635 A lot of time I struggle with this: LArray: array[0..SOME_CONSTANT - 1] of Int8; I can see this language construction a lot, especially when dealing with POSIX APIs that have a bunch of constants. I would love to be able to write this in the syntax below: LArray: array[0. It means we have the range of values from 0 til SOME_CONSTANT - 1, or more generally, from start inclusive to end exclusive. This looks more expressive to me :D https://quality.embarcadero.com/browse/RSP-16635

Delphi 10.1 changed something with regards to overload resolution, causing the following to stop compiling: type   Func = reference to function(const Arg: T): R; type   Alg = record     class procedure Exec (const f: Func ); overload; static;   end; ... Alg.Exec (integer.ToString); This compiled in Delphi 10 update 1 but does not compile in Delphi 10.1 update 2, instead failing with "E2250 There is no overloaded version of 'Alg.Exec ' that can be called with these arguments". Thinking this was a regression, I tried to narrow it down a bit further, but found that even in Delphi 10 I cannot get the following to compile: type   TRec = record     x: integer;   end;   TRecHelper = record helper for TRec     function ToString: string; overload;     class function ToString(const Value: TRec): string; overload; static; end; ...   Alg.Exec (TRec.ToString); This fails with the same message. If I rename the function TRec.ToString() so that it is not the same as the class funct

Stack Overflow just awarded me a secret Winter Bash hat titled "Mild Mannered". Either this is a joke, or their algorithms are seriously screwed up!

I found that FMX mobile platforms does not support local invalidation! This means that all controls on a form are repainted every time any control invalidates anything. I hope I am wrong or at least a workaround can be found. My findings are in this SO question: http://stackoverflow.com/questions/41361668 Any suggestions for a workaround on iOS?

Fast Reports issues in support ticket #255848 have been fixed :-)

Originally shared by Thomas Mueller (dummzeuch) One thing that irked me since forever is that Grep does not find the text in all files that are used in the project. You can either find files that are explicitly included in the current project (or project group) or files in a directory. There is no way to get all files that are linked into a project, look them up in the search path and then grep them. I have got one idea to fix that problem: 1. Read the map file (segments is enough), collect all modules mentioned in any of the lines in Detailed map of segments 0001:00000000 0000B47C C=CODE S=.text G=(none) M=System ACBP=A9 0001:0000B47C 00000730 C=CODE S=.text G=(none) M=SysInit ACBP=A9 0001:0000BBAC 000018D0 C=CODE S=.text G=(none) M=System.Types ACBP=A9 0001:0000D47C 000009CC C=CODE S=.text G=(none) M=System.UITypes ACBP=A9 (M=xxxx is the module name, there will be lots of duplicates.) 2.

Hello everyody! I'm getting a strange error using the component TNotificationCenter on an our customer pc with Windows 8.1 installed. When I try to create the object I get an EOleException telling me that the notification center is not available. Obviously on all the other computers it works fine. Could it be Win8 corrupted? Anyone experienced something like that? Thanks

I've got a problem with Delphi FMX (Berlin update 1) on iOS (10.2). I have a scrolbox with TEdits. The scrolling works like a charm as long as I don't touch a TEdit as first. When I do that de TEdit immediately receives focus and shows the virtualkeyboard. The normal platform behaviour should be that de TEdit only receives focus when you tap on it. Not when you start a scroll on it. Has anybody got a solution for this problem?

Calling all Cryptography knowledgeable people... I am try to decrypt what MySQL does with AES_ENCRYPT, ( https://dev.mysql.com/doc/refman/5.5/en/encryption-functions.html#function_aes-encrypt ) but on the client side (yes, I know there is AES_DECRYPT but that means passing the key across the wire, something which would be prefer not to happen). It seems that MySQL uses AES-128, ECB, and that Java's Cipher.GetInstance("AES/ECB/PKCS5Padding") can decrypt it... but I want a Delphi version. I did find this answer of StackOverflow ( http://stackoverflow.com/a/9298728 ), which I changed CRYPT_MODE_CBC to CRYPT_MODE_ECB = 2; but that fails also (with "System Error. Code: -2146893819.

In the department of wishful thinking: type TElement = class(TSomeClass) Sibling: TElement; end; type LinkAttribute = class(TCustomAttribute) FLink: TElement; constructor Create(aLink:TElement); end; TContainer = class X1: TElement; [Link(X1)] //<-- wish I could use an attribute to link X1 with Y1 Y1: TElement; X2: TElement; [Link(X2)] //<-- wish I could use an attribute to link X2 with Y2 Y2: TElement; end; It would be nice if attributes could reference class/record local fields or properties. I know - it would put a lot of load on the compiler / linker. If the compiler was two pass, order would not be important. Since the compiler is single pass - perhaps something like TContainer = class [Link(forward Y1)] X1: TElement; Y1: TElement; [Link(forward Y2)] X2: TElement; Y2: TElement; end; could be an option as well. #MoreDeclarationLessCode

I found a bug? in TOpenDialog from Delphi XE to Delphi Berline while compiling the demo project cyComponents 6.73 demo\cyComponents\InternetExplorerWrappers\cyWebBrowser (Cindy components) There are 8 htm files Try with the "Load from File " button to just stroll trough first 4 htm files. You will see the file data on the right of the TOpenDialog component. Now here is the bug. next stroll to "Testing unicode big endian file.html" you see nothing on the right pan. STROLL BACK to other files NOW YOU SEE NOTHING. I loaded the file "Testing unicode big endian file.html" to web browser it is OK and one see its content. !!! So it is a "legal file" Obviusly the bug has nothing to do with the demo only the TOpenDialog component.

Here's another question. For reading books (fiction, science fiction, fantasy, biography, etc) I have almost exclusively moved to Kindle. However for technical books I'm undecided. I'm looking at some C++ books (I know but the topics immaterial to the question) and whether to get eBooks or Paper books (the reason for the third item is that for Nick Hodges book's I have both, 'cause I'm greedy). So what should I do...

Hi Guys. I have developed an Outlook Add-In which supports the sorting of mail via speech, using existing speech technology (in my case Dragon, but it should also work with the speech support of Windows I guess). I am looking now for Beta Testers but cannot find them. Has anybody of you an idea where to look for them? The persons I am looking for should ... 1. Be willing to test unpaid and based on the sole incentive that they will never have to pay fo the add-in and their Beta license will be exchanged for a real license once release-ready. 2. They should use speech reckognition technology on a daily basis 3. They should use Desktp MS Office (Outlook) between 2003 and 2016 (I tested so far only with Outlook 2010 - so willingness to have Teamviewer based troubleshooting/bughunting - sessions would be a plus. Any ideas or interest - Beta should start probably around February 2017.

At the absolute bottom (click VCL/Miscellaneous) DevExpress states "With v16.2, the Layout Control is integrated into majority of our dialogs to improve UI element alignment at any DPI setting and achieve better quality when rendering on transparent backgrounds.".

If you plan to publish an app to the Windows Store via the new integrated Windows Store deployment in Delphi, you should do it now. Microsoft is currently providing extremely good support for getting your first app published. Currently there is still a separate review process in place at Microsoft to get your app into the store. As soon as you apply for getting your developer account at Microsoft unlocked for being able to get your UWP bridge apps into the store, they will contact you by e-mail and guide you through the process. The direct and fast support almost feels like having a personal trainer :). Even if you don't have a developer account yet, Microsoft might be glad to give an account for free (may be different in other countries). And it should be noted: Apps developed in Delphi and prepared with the integrated deployment feature are fully supported, and Microsoft seems to be very happy to cooperate with Embarcadero.

I have what might be considered more of a "religious" type of question... Below is a snippet of some Delphi code I grabbed as an example, although my question is about general programmer behavior that is hardly specific to any one language. I've seen this in C/C++, php, and many other domains. Basically, why do programmers do this? Some of you will look at this, roll your eyes and get what I'm saying immediately. Others will stare at it and not see anything unusual. (Note: WHAT the code is doing is pretty much irrelevant. It's the approach I'm pointing at.) -------------------------------------------------------------- procedure TfwReferral.pbSaveClick(Sender: TObject); var sStartYear, sEndYear, sCurrentMonth: string; sClosureDate: string; sCloseVR, sPreviousVRStatus: string; begin Screen.Cursor := crHourglass; if qryReferralInfo.FieldByName('Referral_DATE').AsString = '' then begin OKMessage('Referral Date is required to sa

PackagesGenerator - Automatic Generator Package files for multiple versions of Delphi. https://github.com/errorcalc/PackagesGenerator/ If you are writing a components for Delphi , then you know how difficult it is to maintain multiple versions of Delphi . Usually you get a lot of almost identical dpk , dproj , groupproj files for different versions of Delphi, For example : MyComponents_XE2.groupproj MyComponents_XE2.dpk MyComponents_XE2.dproj MyComponentsDesign_XE2.dpk MyComponentsDesign_XE2.dproj MyComponents_XE3.groupproj MyComponents_XE3.dpk MyComponents_XE3.dproj MyComponentsDesign_XE3.dpk MyComponentsDesign_XE3.dproj ... MyComponentsDesign_RX10Berlin.dproj Tiring create these files manually, also you can make mistakes. ErrorSoft PackagesGenerator can solve this problem! The PackagesGenerator automatic generates the necessary files, doing the necessary internal changes (LIBSUFFIX, contains ...).

Record helpers can do wonders for code clarity. // Never mind the silly example TResult = (CompletedOK, PartiallyPerformed, NothingHappened, HorriblyWrong); function DoSomething:TResult; begin Result := PartiallyPerformed; end; How do we determine failure vs success? if not DoSomething = CompletedOK then ...? What about Partially performed and nothing happened? Enter the helper: TResultHelper = record helper for TResult function Failed:Boolean; function Success:Boolean; end; function TResultHelper.Failed: Boolean; begin Result := (Self = HorriblyWrong); end; function TResultHelper.Success:Boolean; begin Result := not Failed; end; Now we can write if DoSomething.Failed then ... Note that you also can enter the murky waters of obfuscation through helpers, but at least the murkiness will be consistent :P

Hello, I'm using Sir Rufo's TStateless framework https://github.com/SirRufo/stateless I want to adapt my flow (see picture) like this : Implementation type TWarehouseCheckInState = (New, OrderChecked, ProductChecked, CartonAdded, Validated, Canceled); TWarehouseCheckInTrigger = (SetOrder, SetProduct, AddCarton, Validate, Cancel); TWarehouseCheckInStateMachine = TStateMachine TWarehouseCheckInTrigger>; FState.Configure(TWarehouseCheckInState.New).OnEntry( procedure begin FOrder := ''; FProduct := ''; FScannedBarCode := ''; end ) .Permitif(TWarehouseCheckInTrigger.SetOrder, TWarehouseCheckInState.OrderChecked,IsOrderValid); FState.Configure(TWarehouseCheckInState.OrderChecked).OnExit( procedure begin GetCommandeFournisseur; end).Permitif(TWarehouseCheckInTrigger.SetProduct, TWarehouseCheckInState.ProductChecked,IsProductValid ); FState.Configure(TWarehouseCheckInState.Product

Quick Question about TInterfacedObject: if I subclass TInterfacedObject is it necessary to include an interface or it is implicitly assumed the IInterface? So, are these two the same: TmyClass = class (TInterfacedObject) and TmyClass = class (TInterfacedObject, IInterface) Thanks

What am I missing here? FMX Anniversary edition. I placed a Popup menu on a TButton. One of the TMenuItems in the Popup has a submenu TMenuItem. When I run the application and right click on the button, the popup appears as it should. But then when I hover over the the TMenuItem that has a submenu, although the submenu appears, the TMenuItem's OnClick event is not generated. Works in VCL, where I use this event to populate the submenu with, for example, recently opened files. Downloadable sample: http://www.fieldtestedsystems.com/download/testpopu.zip

I'm having problems with Delphi 10.2 Berlin Update 2 and tDSRestconnection by receiving tStream from Rest Server ... but not always: function getfilefromserver(vFileId:longint; vFilePassword:string; vDestinationFileName:string):int64; var vData:tStream; vFile:tFileStream; begin result:=0; try vFile:=tFileStream.create(vDestinationFileName, fmCreate); vData:= fClientModule.directfilereceive_byId_v2(vFileId, vFilePassword); vfile.CopyFrom(vdata, 0); result:=vfile.size; finally if assigned(vfile) then begin vfile.free; vfile:=nil; end; if assigned(vdata) then begin vdata.free; vdata:=nil; end; end; end; The Problem is, that vDATA is shown sometimes in Debugger as vDATA = () and in that case i get an exception, but most of the time the vdata has properties like .size etc and is working. Is this a bug in newest Delphi or i'm doing someth

I'm having an issue with Firedac and stored procedures on SQL running on azure since 10.1.2? I have a service application that processes orders and updates the status, since the latest update I'm getting an error "parameter not found" after x executions of the stored procedure. Anyone having the same issue?

Hello guys, FireMonkey fits pretty well for desktop and mobile apps development, now we have wearables and smart tvs, the game has changed, the UI/UX experience on these platforms is pretty unique, although FireMonkey could run on watchOS or tvOS it would not follow the guidelines, I think it is not possible to mimic their controls, for example, watchOS has a very particular UI experience (the GUI elements have a limited API comparated to iOS) and there the guidelines has been taken seriously, the same sense applies to tvOS, but these are unavailable for Delphi. Despite the fact we have only 32-bit macOS support, without access to Storyboard file it would not be possible to enjoy MacBook 2016' TouchBar support without having access to Storyboard file. Without having access to the underlying XCode project it is not possible to enable Application Extensions in Delphi apps for iOS as well. I don't see workaround for the lack of integration with XCode and Storyboard. It would be am

In Berlin Anniversary, I'm working on a new FMX project for OS X. I have a form with a TTabControl that contains two TTabItems. However, Self.ActiveControl always is the value of one particular component (a TStringGrid) on one of the tabs, even when actually I'm typing into a TEdit box on the other TabItem. To simplify the problem, I created a tiny program. However, in this program I have a different problem: regardless of which tab and which component I'm on, Self.ActiveControl is nil! Shouldn't it be the current control that is active? I'm bewildered and not sure what's going on. Sample tiny test program is here: http://fieldtestedsystems.com/download/testproject.zip (it uses CodeSite for logging.) As often the case, I'm sure (and hopeful) this is just some careless mistake or misunderstanding on my part. Thanks for any help on this. http://fieldtestedsystems.com/download/testproject.zip

Does anyone have experience using the JCL Exception dialog for Delphi? I have tried several times but it fails with "...cannot find .dfm". I end up with a .pas file that has TExceptDialog = Class (TTForm). Huh?

Hi, I've created a C to Delphi converter. Because it's been so useful to me that I've decided to share it. It converts C code as-you-type, and it keeps track of where the original and converted code is. For fun, you can even run the result (using DWS). Disclaimer: this is not intended to be a school example on how to build a parser or anything. But it will convert almost anything that you throw at it. You can download an executable from GitHub (under the releases-tab). https://github.com/WouterVanNifterick/C-To-Delphi https://github.com/WouterVanNifterick/C-To-Delphi

Delphi Generics - Please Improve Compiler and Linker to avoid extreme Bloating compared to C# Based on the discussion during the last few days I decide to create a test sample to compare Delphi <-> C#. see https://quality.embarcadero.com/browse/RSP-16520 Not that I expect that something will happen to improve but in German we say "Hope is the last to die". https://quality.embarcadero.com/browse/RSP-16520

How do I make the CTRL / SHIFT keys being pressed/released change the state (eg., color) of a TLabel under the mouse pointer without relying on the TLabel's mouse event handlers? (VCL, not FMX, in case it matters.)

So the next release is named Godzilla for real. At least they have sense of humor.

I have a situation where, for the first time, I need to create about 100 SQL queries to extract various data items for a report. I've seen lots of apps that have dozens and dozens of TQuery-like components on them that each contain specific queries, and others that have long lists of string const definitions that contain the queries as strings that are loaded into a single, often dynamically created, TQuery-like component. These queries will never need to change unless some program requirement changes. Most of these queries will require a date range as parameters, but not many other parameters. Aside from the obvious approach, where you'd create each query and test it in a SQL query manager tool of some sort, then paste it into a query component or put it in a static list that's stuffed into a TStringList or similar, are there any tools or approaches that make it easier to do this and get the queries back into the source code, or as form resources, or something along that l

I am trying to use the Parallels library to delay the execution of a procedure. My first thought was to use Sleep for the duration I need but it doesn't seem a good idea. Then, I came up with this approach: i:=10000; repeat task:=TTask.Create(procedure begin Sleep(1); end); task.Start; TTask.WaitForAny([task]); until i<10000; Listbox1.Items.Add('10 Seconds'); in an effort to make the app responsive but it looks like the behaviour is the same. The app is totally blocked. Does anyone have a procedure to share? or thoughts how to make this happen? Thanks a lot.

Does anyone feel necessary introduce method keyword to live together procedure/function keywords? Or even have functions without return type? These days the distinction between procedure and function nomenclature no longer exist.

Err Embarcadero Technologies, I upgrade to Berlin 10.1.2 the day that it came out. Surely you should know that (since a license check is done)... so why spam me?

It was mentioned many times that Embt will introduce nullable types into Delphi. I was wondering what it will look like. However, is that really on top of our wishlist? I don't think so. (especially without null-propagation or swift-like nillable) we have Nullable in Spring4D. Instead, I would suggest Embt consider introducing standard function *NameOf* and *interface helper* . These two features will fundamentally changes a lot of things with "minimum" cost (In my mind of course).

colleagues I'm trying to make localSQL with FireDAC. Evrithing is OK but select account, sum(amount) mnt from NUMBERLIST group by account leads to "mnt" become string. When I remove "group by" it comes to be float again. Any Ideas? CAST() doesn't help.

Now what is that? I've created a new package and installed it in the IDE. In the package there are a few units. I added a new one and now the IDE recognised the old ones and suggests the new name. But when I try to compile, it says the unit is not found. Any ideas what is wrong here? Thanks
