Marco Cantù An IDE feature to comment all lines with sysntax error (or code lines lacking definition of variable name/object/classes etc) within a pas file or even entire project can help faster compilation of projects for analysis purpose and a gauge of estimation of effort in terms of LOC (lines of code) requiring change The feature can be a great help in estimation of required effort for migration projects from earlier IDE versions to later

AARRGHH ! I can't reproduce this bug but I want to report it here. On a project under Tokyo, I use an avanced JSON Unit based on the one I've published on my web site. http://lookinside.free.fr/delphi.php?Delphi+XE8+et+JSON at application startup, I read a Record from a JSON file, it contains the application configuration. But after some change in the code (not related to JSON nor the Record), I've hit F9 and the application starts to do strange things...the problem was about the configuration. I've followed the JSON parsing to find out that the TypeInfo informations where corrupted. It was a Record TypeInfo with the rigth name but with fields informations from an other Record ! So my JSON Parser just dropped the values because nothing matched the record definition. I just had to rebuild the project to fix that nasty bug. not cool :/ http://lookinside.free.fr/delphi.php?Delphi+XE8+et+JSON

I'm migrating a VCL app to FMX Mac OS. Our application opens .png files that newly appear in a specific folder. These are created by a third party app. We display them in a TImage as "pseudo-video" at about 10 fps. We don't mind if we drop files now and then. In Windows, we chose not to use the Windows hooks that are available to monitor folder events. We simply use a TTimer, calling TDirectory.GetFiles once a second and looking for a file we haven't already processed. We delete files after we've processed them, so the file list doesn't get too big. In Windows, before actually opening an image for reading, we check if it is still open by the third party app with this code: function FileClosed( const aFileName: String):Boolean; var hInputFile: THandle; begin hInputFile := CreateFile(Pchar(aFilename), GENERIC_WRITE, 0, nil, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0); Result := (hInputFile INVALID_HANDLE_VALUE); if Re...

Edit: Nevermind - RangeCheck was off. Should this code create an Index out of bounds error? type TArrayType = TArray ; procedure TSomeClass.GetArray(var anArray: TArrayType); begin SetLength(anArray, 10); for ix := 1 to 10 // Should have been 0 to 9 do anArray[ix]:= ix; // end; procedure Test(SomeClassInst: TSomeClass); var Arr: TArray ; begin SomeClassInst.GetArray(Arr); // do something end;

Hello! From a Delphi application, we need to apply an XSLT transform to an XML file into an HTML page. This is mostly done, but we are receiving a CRLF sequence in the XML that is impeding certification because a little (but very important) piece of data is displaying incorrectly. We have tried to use fn:replace but there are no examples on how to use it with the content of a tag. Does anybody have pointers? Thanks :)

Before I start implementing it myself: Is there already a debug visualizer for Delphi 2007 (and possibly even older versions?) that displays: * TDateTime as date / time string rather than a floating point value? * Multi line strings / TString/TStringlists as the formatted strings rather than 'bla'#$D#$A'blub' I'm mostly interested in the watch window, but support for the "Evaluate/Modify" dialog would also be appreciated.

In recent versions, we see many new components for Win10 apps. What strikes me though is that one can use them in VCL apps. Shouldn't those Win10-specific be avail for FMX as well? And the same goes for Metropolis apps. I feel like EMBD forces me to go to VCL if I want a modern Win app. But I still want to do cross-platform development for my own apps.

And here is why I think twice before spending time to report feature requests to QP And even bugs/unexpected behavior are regularly being sweeped under the carpet reclassified as new feature. 46 out of those 84 resolved/closed have the resolution "wont fix" or "works as expected". This is not intended to be a flame but just pointing out the lack of emphasis on new features (at least those being reported in QP) FYI: Marco Cantù David Millington Horácio Filho

What's the point of having abstract classes in Delphi? Is there any use case? Hey, you can instantiate an abstract class just fine (no compiler error, warning, nor hint). You can even USE such object just fine Yes, I know, the docs: http://docwiki.embarcadero.com/RADStudio/en/Classes_and_Objects_(Delphi) Note: Delphi allows instantiating a class declared abstract, for backward compatibility, but this feature should not be used anymore. So, Delphi got this new feature called abstract classes on Delphi 7. That was in 2002 IIRC. So fifteen years later all we got is a just a highlighted keyword? I'm completely shocked /rant off

Change TDateTimePicker.format to yyyy-MM-dd HH:mm:ss but the TDateTimePicker.kind only can set to dtkDate or dtkTime, so if i change the date and time together on UI, only the date or time changed in TDateTimePicker.Datetime. Which means, if i wanna get the date and time together, i should put TWO TDateTimePicker on the form. Is that possible for you to update the src to improve it?

Coworker and me were just thinking if this (or similar syntax) would be nice to have in Delphi: car := TCar.Create begin Name := 'Chevrolet Corvette'; Color := TColors.Yellow; end; Edit: After pointing out this might lead to code defects because begin end can be used regardless this feature here is another proposal (similar to how Oxygene does it): car := TCar.Create( Name: 'Chevrolet Corvette', Color: Colors.Yellow, MaxSpeedKm: 300 ); With a ctor that has an argument: car := TCar.Create('Chevrolet Corvette'; // Color: Colors.Yellow; MaxSpeedKm: 300 ); Suggestion by Eric Grange - like the original one but reusing the with to make it safe against issues using begin : car := TCar.Create with Name := 'Chevrolet Corvette'; Color := Colors.Yellow; MaxSpeedKm := 300 end; Ctor with parameter: car := TCar.Create('Chevrolet Corvette') with Color := Colors.Yellow; MaxSpeedKm := 300; end; Similar to how since C# 3.0 you can initial...

I have a debating at work with developers with knowledge about .NET and Java, but minimum knowledge on Delphi. Debating is about using an architecture based on POJO objects instead of using TDataSet on a server application. I can't see any advantage of excluding the use of TDataset built-in functionality, and to create a small framework based on classes which map the tables from database. Server application is not designed to perform heavy CRUD operations. It just feed several .NET clients with data using RemObjects. I see a big disadvantage to create a plain class to hold values from a SQL select statement, instead of using a dataset. When the SQL is modified, or a table is modified, then all the classes need to be modified also. On the other hand, if using TDataset, developers should dedicate a small time involved to learn how to use Delphi datasets. Any thoughts on this?

Some while ago I started a plugin to easily add units to the uses clause just like you can do via quickfix in VisualStudio. I never actually polished it but since I felt it might be useful to others as well here it is (still beta - supported Delphi versions currently are 10, 10.1 and 10.2). Just run the setup and install into a directory where the IDE will also have write access to (should be %localappdata% by default). When you first start the IDE with the plugin it will index $(BDS)\source which should reasonably fast and you won't even notice it. You can then add additional directories via Options -> Third Party -> UsesHelper (or F6 -> UsesHelper). Just add any additional directories that should be indexed (recursively, only *.pas). Indexing will happen in the background. In the end it will save an index.dat file which it will only access when it gets changed or you restart the IDE. Via shortcut (Shift+Alt+F10 - fix for now, might be configurable later) while in the edi...

Anybody else noticed this inconsistency (using Berlin 10.1)? extractfilepath ('\\192.168.0.1') results in '\\' extractfilepath ('\\2001:db8::1') results in '\\2001:db8::' Looks to me like extractfilepath isn't IPv6 aware yet, because it seems to think that the "1" at the end of the IP is a filename, not part of the path. I checked, and extractfilename ('\\2001:db8::1') indeed results in '1'.

Still can't get Rad Studio 10.2 to install on my laptop. It'll install now, but then it can't load several BPLs and then it crashes before the IDE gets loaded. I'll probably go back to 10.1 for now after trying one more time. This laptop is a Lenovo z70-80 with 12GB memory and 800 gb space available. It's a Core I7 machine. It ran Berlin fine. It could still be a corrupt ISO.

It just occured to me that when I have such code: type TFooBar = class s: string; end; procedure Main; var x, y: TFooBar; begin x := TFooBar.Create; y := TFooBar.Create; x.s := 'True'; y.s := 'True'; Assert(Pointer(x.s) = Pointer(y.s)); end; begin Main; end. The assertion will raise because whenever you assign a string literal to a string variable it checks if the string is a const (refcount = -1) and then calls _NewUnicodeString). I guess this has been discussed already somewhere else but I cannot find anything regarding my question: I would guess that even if it is a const it could assign that reference to s and don't touch the refcount. This should work fine with the cow mechanics. But as it is this would mean that if code runs through such const string assignments every time a new string gets allocated, no? In my case I am using the const string 'True' for nullables in Spring to set the "HasValue" flag for them (otherwise ...

Licensing issue: has anyone experienced this before ? Using Delphi 10.1 Berlin Update 2 Pro with subscription... It's been a few days now, Delphi starts as usual and I can work with it but when first compilation finishes, Delphi IDE closes and launches a web browser to a URL with incorrect license registration. I ignore it, restart Delphi, re-compile the project, and it now works as expected. And it continues to work for some time. Then, this happens again. Running the license manager: no problem. Any idea of what could be going wrong here ?

For everyone interested in having nullable basic data types in Object Pascal I suggest looking at my new OLTypes library available at https://bitbucket.org/mihoor/oltypes/wiki/Home . The new types are: OLBoolean, OLInteger, OLCurrency, OLDouble, OLDate, OLDateTime and OLString. I've put each basic data type inside a record type with a flag for being Null and overloaded operators. As a huge bonus, there are some usefull methods for each data type. Concider this quick example:

Android question... This might sound ridiculously simple to do but cross platform API isn't my strong point. I started an Activity with the Intent of consuming content from the Gallery which works fine. However, the Intent returns the URI of the file (as content://storage/... /media/12345) instead of the actual file path. I was expecting something like '/storage/emulated/0/.../VID_18161918.MP4' Any pointers? UPDATE ---- after going through the Android documentation and some examples (that probably work in Java). This is the code which I 'feel' should work.. but it is not... any help would be great function TForm2.HandleIntentAction(const Data: JIntent): Boolean; var P: TJavaObjectArray ; C: JCursor; I: Integer; begin Memo1.Lines.Text := JStringToString(Data.getData.toString); // this returns the URI in string perfectly... so I know that I am getting the file path properly // this is to prepare the information I need... they call it projection P := TJavaOb...

Seems that FMX has some weird alignment logic. I cannot look closely at the moment, but it seems that it calculates alignment order based on original x (y) position of child control and its width (height) and documentation states that alignment can change control position and size.

Continuing the theme about "True Native Crossplatform Delphi Library" During the development of my framework. I ran into serious limitations in Delphi - Android bridge. Namely, in limiting the number of simultaneously used classes (~30-40). What does it mean for developers? It means, that you cannot use in your android application more that ~30-40 classes in the same time. Once you exceed this limit, your app will fall in different places on the Delphi side. However it doesn't limits on instance count, which are allocated from one class. In other words, you can create alot of object java instances of one class, but you cannot create by one object of a lot of java classes. Since FMX is not very integrated with the native API, this issue while it is not critical. Because you are "in a bounce of limit". However, if you want to limit yourself to just Delphi with a functionality, and still use the android api directly, it can become a very serious problem in future. ...

True Native Crossplatform Delphi Library (spoiler) Hello gentlemen, I'm glad to announce 3 news in Delphi world: 2 positive and one negative. I had been working on development FireMonkey library for 5 years in Embarcadero. It was a usefull time for deep understanding how library should work. And after closing offices i have been started to work on creating new crossplatform really native library from scratch. It never uses firemonkey anymore. Library something similar to VCL, but uses modern approach in development. It uses only small part of rtl. Framework uses native components and native graphics of each os. There are few advantages, which will be available in final version: 1. Look and Feel. All components are native. It means they are using native implementation system components aka VCL. Now you don't need to worry, that your application works on android not so like a application, which was created in XCode or Android Studio. 2. UI response. All components of new library ...

A simple free class, experimental version, of a variable length data reader / writer using any TStream. https://github.com/davidberneda/VariableStream Add, change, delete or get items of variable length (for example: strings) from / to streams at fast speed. One stream is used as the index to another stream containing the data. Streams can be TFileStream, TMemoryStream or any other kind capable of reading/writing bytes. Pending: "trim" method to pack streams, optional sorted index for quick deletions (at the expense of slower random access), "array of T" automatic support https://github.com/davidberneda/VariableStream

How do you build 32bit apps. in a 64bit machine? I was trying to install an old VCL component but I got the following error: [dcc64 Fatal Error] ATReg.pas(20): E2213 Bad packaged unit format: c:\program files (x86)\embarcadero\studio\19.0\lib\win32\release\designide.dcp.DesignIntf - Expected version: 32.0, Windows Unicode(x64) Found version: 32.0, Windows Unicode(x86) In the docuwiki this is all I found: "For Win64 applications you need to create a 32-bit version of your component on this page of the wizard. Later you should compile your component again as a Win64 component" http://docwiki.embarcadero.com/RADStudio/Tokyo/en/New_Component In the options tool menu it list the win32 SDK but can't compile 32bits applications, I know using a 32bit OS to build 64bits apps it is necesary to connect to a 64bit machine but can't find info of doing it the other way, 64 to 32. http://docwiki.embarcadero.com/RADStudio/Tokyo/en/New_Component

This puzzles me ... Why would an Anroid App that is running fine in Debug and Release Mode crash when I deploy it to the AppStore and install it from there - on the very same device? This is what happens to me at the moment with one of my apps. I goes to Nirvana right after the splashscreen, but only if I install it from the appstore. The problem is that I have no idea how to troubleshoot the issue. Has anybody ever experienced similar? It is no general problem with the app in the appstore on another device this does not happen and I can install the app from the appstore and it runs. The device where it is not running from the appstiore has an Android 6.0 and the device where it is running has an Android 5.0 installed. So I guess it has to do with this difference?

Does anyone have a modern (fast) implementation of a heap data structure handy. If not I'll throw something together using The Tomes. http://www.cprogramming.com/tutorial/computersciencetheory/heap.html

Slightly Off Topic: Any recommendations of automation tools for GUI testing. We tried AutoIT but it had some problems and way too technical. I would guess that if it would be commercial product, price should be pretty moderate and licensing model fair anyways (). Free and/or open source projects would be preferable.

Is this bug known? type IX = interface ['{2F2B4306-3427-43C7-8D86-A3E300501281}'] procedure Test(NormalParam: boolean; DefaultParam: boolean = true); end; TX = class(TInterfacedObject, IX) public procedure Test(NormalParam: boolean); end; Even though the implementation does not match the interface the compiler does not issue any hint, warning or error. IMO this should be an error.

The joys of code optimization http://delphisorcery.blogspot.com/2017/05/i-wish-i-had-dcc32-dontmakemycodeslow.html

I have the following situation: I have enumerator classes that have a MoveNext and some internal state. The first time MoveNext is called additionally to the usual logic of MoveNext it needs to do some initialization. Currently the code is basically like this: function TEnumerator.MoveNext: Boolean; begin Result := False if state = init then begin DoInit; state := running; end; if state = running then begin // usual movenext stuff... end; end; In languages with case/switch fallthrough I could simply write it like this: case state of init: begin DoInit; state := running; end; running: begin // usual movenext stuff end; end; I am seriously tempted to use a label and a goto here but I was wondering if anyone has another idea to avoid checking state twice.

Is there a reason TTimerProc used with IFMXTimerService is declared so, without sending through the TimerID/Handle to the callback procedure (in FMX.Types)? TTimerProc = procedure of object; IFMXTimerService = interface(IInterface) ['{856E938B-FF7B-4E13-85D4-3414A6A9FF2F}'] function CreateTimer(Interval: Integer; TimerFunc: TTimerProc): TFmxHandle; ... end; With the ID/handle it would be possible to use one TimerProc handler for multiple timers created this way. Looking further into the FMX.Platforms.xxx units I can see the ID/handle is available upto the point of the call to TimerProc (ok on Mac/iOS it will be more involved to get the ID, but it seems possible). Is there an easy way to use the same callback procedure for multiple timers created this way and know which timer fired?

Hi all. I have a windows 10 store app. Its in the store. But there is an issue with the new up and coming windows 10S (student version?), i.e a permission issue with the creation of the apps settings file...normal windows 10 with full resources allocated (that is enabled for the app by default, no way to change that?), using gethomepath, works OK, but for windows 10s I am told I need to create the files inside the installation folder. Using location:=ExtractFilePath(ParamStr(0)); it does not like either (normal windows version, permission error), as that is a folder under c:\program files. what co mmand, like gethomepath, to use, to get the windows 10 installation folder location? thanks! , Brian
