I cannot find a solution to a doubt that came out while reading Primož Gabrijelčič's book. Any hint? https://stackoverflow.com/questions/51116812/delphi-tthread-handle-error https://stackoverflow.com/questions/51116812/delphi-tthread-handle-error

Marco Cantù has pointed out in his blog ( http://blog.marcocantu.com/blog/delphi-blog-week-60.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+marcocantublog+%28marcocantu.blog%29 ) something really important for the Firemonkey mobile developers. As far as I know, this is the first multiplatform memory leak detector (tested for Android, Win32, Win64) that exists for Delphi: https://bitbucket.org/shadow_cs/delphi-leakcheck .

I've made available, with permissions from the author, an open source version of King Calendar - one of the early Delphi components back in Delphi 1 - 3 days and was basically abandoned. I've broken out to proper run and design time packages years ago and had kept it updated through the various versions of Delphi. I've made available via GitHib and am starting with Delphi 10.2 Tokyo packages sne then later adding earlier packages. I've also made 64 bit packages. The original demos were tweaked and also 64 bit versions made and tested. I've taken the original documentation (credits had included Nick Hodges when he was in the Navy, to show how old the component was, and converter the no longer supported help format to RTF. https://github.com/K7LER/KingCal

Is there a standard (generic) function that uses RTTI to compare the contents of two class instances and say whether they're the same or not? (I'd like something that lets me assign an attribute to certain fields to be ignored, and then use a loop that compares values based on their type to report if all the other fields match or not, without having to write an if...then for every field in the class. Surely something like this has been written dozens of times by now!) In this instance, the fields are all built-in types except there's one TStringlist field.

Question for anybody using a vcs in a team with Delphi projects: how do you manage your Delphi Project file(s)? [I don't know what category this belongs in -- it seems like it should be something like "Delphi Workflow".] Two different issues: First, do you assume everybody has the same footprint and can run the same project file on their machine unchanged? Second, when someone decides to "upgrade" a file because of significant changes, and decides to change its name, say from Form22a to Form22b, how do you ensure that everybody else's environment actually replaces Form22a.pas/.dfm with Form22b.pas/.dfm, including the relevant lines in the project file? (Will git, say, remove Form22a.* from the environment and then add Form22b.* ?) Related, when someone ADDS a file to the project, the project file needs to be updated. Also, when a new library is introduced that's needed on one form but not others, the search paths probably need to be updated in the proje

I have been on to this thing a couple of times but i have not been able to express myself clearly enough previously and so no one with the skills has been able to find a viable solution or even understand what I’m on about. I work i a VM (VirtualBox). If the host and the VM both has 100% both this is not a big problem. But when the host has a smaller (15 inch) scaled 4K screen and the VM is forced to use scaling, the painting of the IDE gets slower. If the host has 250% scaling the paining in the VM is even worse. Syrup. I usually have the IDE in MDI-mode, i think that is what it is called. I have a docked set of windows to the bottom (100% width), one docked set to the left (commonly structure, object inspector) and one to the right (project manager, tool palette, et. al). The problem is that when the IDE switches from Default Layout to Debug Layout it takes too long to repaint everything in the above described circumstances. Key here is of course that the Default and the Debug layout

Suppose you have a package consisting of source files residing in dozens of subfolders of a root package folder. To create a .dpk file from IDE I need to browse into each subfolder, select all *.pas files and add them to the package. Is it possible to automate it, for example by just clicking on a root package folder so that all *.pas files in its subfolders are added to the package?

I'm profiling some code trying to improve its abismal performance. I'm using AsmProfiler ( https://github.com/andremussche/asmprofiler ). The problem is, when running my program with the profiling code in place, it runs way faster than when I compile it using Release settings. Of course, I need to check the configuration for each profile, but, how can this be possible at all?

Indy EidHTTPProtocolException? I use TIdHTTP to download an image from a web location to a memorystream. I use the following code: tmpMemStream:=TMemoryStream.Create; try tmpIdHTTP:=tidHttp.create; try tmpURL:=' http://logo.clearbit.com/'+tmpURL ; tmpIdHTTP.Get('http://(proper url)', tmpMemStream); tmpLogo:=TBitmap.Create; tmpLogo.LoadFromStream(tmpMemStream); finally tmpIdHTTP.Free; end; finally logo:=tmpLogo; tmpMemStream.Free; end; The above code used to work for a few years but recently I realised that it generates an EIdHTTPProtocolException with the following error:"HTTP/1.1 301 Moved Permanently" When I try the URL in my browser, the image shows correctly but my code fails. Any ideas what may be wrong? Thanks

Hi, (I'm using Delphi Tokyo) Is there a way to use the same Build number for Debug and Release? As I understand the IDE keep separated build count for each build configuration. Is there a way to unify debug and release per platform? Today my project show debug build as 781 and release build as 62. It is very hard to track errors in source code this way. How do you guys managed it? Is there a tool to generate a common build number? Thanks, Clément

I have two issues with TSaveDialog. 1) It always appends the extension to the filename even if the filename already has the extension. Resulting in a filename with two or more extensions. 2) When I compile my project inside the IDE the TSaveDialog and TOpenDialog uses the new Windows vista style. When I compile the project via command line, using the exact same settings, the dialog paints with the old style. Anyone with these issues? Thanks. Edit: using Tokyo latest release.

VLC in FMX forms? I've seen some solutions where you can embed FMX forms in VLC apps. I want to do the opposite for Windows only. I can show a VLC form from within a FMX app but when I am trying to embed a VLC frame I can't do it. Does anybody know how to do it/done it? Thanks

How to auto close Message View window on successful compilation . This was asked for in Delphi 7, but it seems with Delphi XE3 (what I'm using) it's still not possible. Anybody know of a 3rd party add-in or hidden Delphi setting that will close the Message View after a successful compilation? If I save my "desktop environment" while the Message View window is closed, then compile it doesn't display the Message View - if no errors occurred. If a error occurs, then the Message View automatically appears. After I fixed the compilation error and recompile, the Message View stays there and doesn't close. At this point I want it to close automatically. It is so damn annoying. I need all the screen (editor) space I can get, and the always visible Message View is taking up vital space. Any known solution for this? Once again, Lazarus IDE does this perfectly. http://www.delphigroups.info/2/12/275159.html

I'd like to "modernize" my program's GUI and I thought the ribbon could be the answer. I opted for the Windows Ribbon Framework for Delphi. I encountered two main problems: 1 - the ribbon only works inside IDE. When I execute either Debug or Release version I obtain nothing. I see the program in Task Manager for a couple of seconds using 50K of RAM max and than it disappears. 2 - I tried to update the library to the last version. I did what had to be done uninstalling the previous and installing the last one, but I cannot place a TUIRibbon on a form. I only get an invalid handle error. I don't want to start a discussion about the ribbon itself. Only its implementation on Delphi. If someone knows a better library to do it, please share. http://www.bilsen.com/windowsribbon/index.shtml

Something strange happened to my IDE tonight. Most of the properties and Events in the DataModules in my project are lost at design time. Even if I start a brand new project, add one empty form and an empty DataModule to the application, the properties are not there any longer. I can't remember I have done anything in the IDE. Do you know what happened ?

Hello, I expect delphi 10.3 to come out before august. As you may know there will be in august an "update" in the play store because the apps will have to target an higher api level. Embarcadero needs to fix this otherwise no more android apps in delphi! Where I work we're moving to Java which is of course better than fmx but the porting process is slow. Is there any fix to this delphi android sdk problem? I have said that I EXPECT the update but I am not sure.

Hello! I am a long time Delphi and C++ developer. My colleagues at work suggested me to learn C# because they said it is a "mix" of delphi and c++; in particular they said that C# share A LOT of things that delphi has. Googling around (curiosty) I've seen in fact that: - C# has a very similar threading library (Tasks (run/stop/wait), Monitor class and the class System.Threading in general (same name as delphi)). - C# has attributes like delphi - C# has diagnostics like delphi - C# has sturctures like delphi (TDictionary, Queue, Stack, IEnumerables and other Collections - C# has datetime/timezone like delphi and a lot more that my collegagues told me! I don't wanna use c++ for cross platform because I don't like Qt. I use delphi for destkop and cross platform BUT firemonkey and delphi's quality (for mobile) is dying. They suggested me to move to C# because it will be easy to learn since I know well delphi and c++. Please let's NOT START A DISCUSSION ON

Are there any videos (not written stuff, but actual videos) that show how you'd set up and use the built-in versioning in Tokyo IDE with a gitlab repo? Especially for multiple team members to work with the same repo. Everything I've seen is sort of like: "This is a key. You insert the key into the lock and turn it this way. Then you can turn the knob and open the door. And there you go. Welcome to your file warehouse." I want to see how people actually set things up in the warehouse and work with them as a team over time. Not how to turn the knob, open the door, and set a box of stuff inside the door. We have a hosted gitlab site at work, and very few tools I've found work with hosted sites. We're having trouble getting Dephi's IDE to work with it. I keep getting my backups scrambled up and can't seem to undo things.

I am having an issue with Fullscreen and FMX... My app is intended to run in full screen, it has more 2 forms besides the main form. I set FullScreen to true on the main form, when I open any other form the it keeps on full, nice, but when I return to the main form it loses the fullscreen, showing the status bar, now I tried to apply Fullscreen to all the other forms, no result. The problem is with the main form only, when I return to it, reading the value of Fullscreen it shows as TRUE, but the screen won't reflect that state.

Hi guys, I'd like your opinion about something. Whenever I need to implement a "Delete" action I get very stressed. Say for example, I want to implement Customers --> Quotes --> Invoices. Apparently, there is functionality to add/edit Customer. Here I am reluctant to implement the delete function straight away because I am afraid that if I implement it before the Quotes/Invoices I may forget to delete them when a customer is deleted. I know databases can take care of this with cascade/etc but many times things are more complex or databases do not have relationships Do you ever get to this stage or it's just me? Should I just implement delete in the sequence of add/edit/delete? Thanks

Having hard times to find skilled Delphi developers here in Spain. Many years ago Delphi was learned at the university and it was easy to find Delphi programmers. Now things have changed and we are living in a Java world. I still think that Delphi is the best suited language for business apps but, when a software company needs skilled programmers and cannot find them it is time to think in moving to another platform. Perhaps Embarcadero and it’s distributors should spend money and time to reach agreements with universities to teach its technologies. What do you think?

Hi! I am did simple a file transfer using Indy. When file is small (ie. 1Kb) the client side receives a 0 byte, but this is due because not getting bytes. Not best solution, but I dont know any other, the receive loop is: LFilename := IdTCPClient1.IOHandler.ReadLn; // while IdTCPClient1.IOHandler.CheckForDataOnSource do begin IdTCPClient1.IOHandler.ReadStream(Strm, -1, false); Application.ProcessMessages; end; When get small files I only receive the LFilename and CheckForDataOnSource if False so my stream is closed without any bytes. If I force ReadStream() by ignoring CheckForDataOnSource it will hang, because it is false. This works fine for large files, but fail to small files because CheckForDataOnSource() gets to False.

Transparencies (use of opacity) in nested controls (FMX). I have a form with a background photo and a partially transparent "panel" (a TRectangle inside a TLayout, with Opacity set to 0,7). I would be able to position another TRectangle over it , covering only a part of that "panel", but, for this control only, without transparencies (I'd need a top, slightly smaller, panel in the center of my form, 100% opaque, to put labels, bitmaps, etc., over it). Is this possible with FMX? This is the best that I can get (reduced opacity is applied also to center panel):

UTF8 decode...it's a bit confused in System.pas... UTF8Decode -> call Utf8ToUnicode but deprecated 'Use UTF8ToWideString or UTF8ToString'; UTF8ToWideString -> inline call to UTF8Decode ! UTF8ToString -> inline call to UTF8ToUnicodeString this needs some cleanup I think :( is it possible to keep at least the System unit a little bit coherent ?

Hello . I need exemple for datasnap . with database Please.

There's something strange i witnessed in our Application (and noticed in the IDE, too). When The Application is minimized and then restored(to maximized), there are a couple of black bars for a few moments. I run Win 10. Someone has any idea? Because for other Applications restoring from minimized is always quite smooth. It only seems to affect VCL-Based Applications. (Happens in Tokyo IDE aswell)

I have trouble running empty FMX application on iOS simulator. Application shows splash screen and dies. I am not using VM, but network connection between macOS and Windows. Any ideas? Tokyo 10.2.3 + PAServer 10.2.1.13 Windows 10 April Update macOS High Sierra 10.13.5 iOS 11.2 SDK Xcode 9.2

Which OpenSSL DLLs to use with Indy 10.6.2 (Delphi 10.2)? On FTP server http://indy.fulgan.com/SSL/ there are versions 1.0.1.* and 1.0.2.*, and I could not find any information what the difference are, and which one to use for Indy. I need those libraries to make SSL/TLS connections to SMTP servers. TIA, Achim http://indy.fulgan.com/SSL/

Help needed I am writing a FMX application with Tokyo 10.2.3 currently for Windows with the intention to move it to MacOS and tablet when the functionality is complete. I use a FlowLayout with several memos on it. the TFlowLayout is placed inside a scrollbox in the hope that the scrollbars become visibible when the memos are positioned outside of the visible area. Unfortunately this is not happening. Can anyone help me here or point me in the right direction? Thanks in advance

So Embarcadero broke the "Default layout" (now always enforces a new "Standard Layout") upon IDE startup in 10.2 Tokyo, and commented on the bug report https://quality.embarcadero.com/browse/RSP-20138 with "Jira-Quality Sync Service added a comment - 29/May/18 2:50 AM Issue is reclassified as 'New Feature'" https://quality.embarcadero.com/browse/RSP-20138

On my Embarcadero renewal quote, I see two items: "Delphi Premium Update Subscription" and "Delphi Ent - Named - Support Renewal". I read this as if I want to retain access to the regular updates, I go for the update subscription and if I want support, I add the support renewal. Is my understanding correct? The Embarcadero representative is suggesting that it is completely the reverse. When others are renewing, which option are they purchasing? Thanks.

Question re FPC and x86 linking to 64 bit library files on OSX 64 bit it seems that the .o file produced is still only 32 bit ?

Well I seem to be good at finding new open source projects, and today's new finding is kyoukai_framework - A Simple Framework for A Small Server Application. Quoting from the author: "I make it for Pascal because I can not find any Pascal web-framework which I really comfortable with. Some are too complicated, while some others have too many dependencies. Basically, I expect an easy-to-use framework like CodeIgniter in Pascal, even simpler than CodeIgniter. This project is too far from a complete framework, it still in the experimental stage, please help me if you have any idea, code, and feature request. And, Don't too silly to open an issue." And the link: https://github.com/afuriza/kyoukai_framework

Generic surprises 1. The generic type is constrained, but cannot be used for class references? type TBase = class procedure NothingAbstractHere; constructor Create; virtual; end; TGenericWrapper = class type TBaseClass = class of TB; <-- [dcc32 Error]: E2021 Class type required end; Is there any logical reason for why this should not be possible? 2. Constructing an instance from a generic type does not flag construction of a class with unimplemented virtual abstract methods. This one I can understand, but it still is annoying. I guess I could factory functions to work around it.

Has anyone update the FastMMUsageTracker dialog to support 64bit? The lastest I could find in git is full of DWORD's and Integer casts, and before I spend the time to try to update it, wondering if anyone has already done it..

We'd like to share some Delphi class to our developer team our junior developer team, but we don't want to share the source (.pas, .dfm), so in base of your experience, wich is the best way to do that? Pros and cons ? Do you know if there are any other methods? Thank you for any suggestions.

Originally shared by TRichView We released a new version of Report Workshop (#VCL components for building rich text reports for Embarcadero Technologies​ #Delphi). In this update, we included a new data provider allowing to build master-detail reports on data from TdxMemData datasets by DevExpress. Web site: https://www.trichview.com

Why Firemonkey will never be stable as HTML5. HTML5 is actual an interface and standard. Android&IOS will be optimized with HTML5 with their updates and Apple&Google will provide better HTML5 support with new version of there OS themself. But FMX requires Emb keep up with both platform.

Help with Code Folding I just noticed that Class Code Completion Ctrl+Shift+C expands all the folded code sections. Is there a way to prevent this behavior? If I fold a section of code I'd like it to stay folder until I open it back up.

Hi all, Can I use a Critical Section to Lock a Private field before Incrementing it?. will this work the same way "TInterlocked.Increment" works.

Hello, I think some of you know BrainMM and some don't. Well, to me it seems a really fast and good memory manager even better than FastMM but in order fix bugs and get it updated the developer needs donations .... So i'm posting it here to see if we can do anything to help this project not to go away. Donations Links at the Github page! Thank you https://github.com/d-mozulyov/BrainMM

This piece of code is Windows only: function MemoryUsed: cardinal; inline; var MMS: TMemoryManagerState; Block: TSmallBlockTypeState; begin GetMemoryManagerState(MMS); Result := MMS.TotalAllocatedMediumBlockSize + MMS.TotalAllocatedLargeBlockSize; for Block in MMS.SmallBlockTypeStates do Result := Result + (Block.UseableBlockSize * Block.AllocatedBlockCount); end; Is there something that is available on other platforms (POSIX) that can give me an idea of how much memory the app is using, without calling native OS functions?

hello, Any good OCR component for VCL ?

Hello All! I have a problem with the next topic. I have a stub DLL that creates sample data for my application. I send to the DLL the Firedac Connection I have configured in the main application, and internally the DLL works well, but when the call returns, the main application is not connected. And it's not possible to recover the connection. I followed all the instructions from this pages: http://docwiki.embarcadero.com/RADStudio/Tokyo/en/DLL_Development_(FireDAC) http://docwiki.embarcadero.com/CodeExamples/Seattle/en/FireDAC.DLLSharing_Sample Does anyone use this technique with success? Can anyone of you help me? Please! Is it a known problem of FireDAC or I made something wrong?

Anyone with some guidance and/or code sample to achieve what I'd like to do in a FMX TListView (not VCL). I'd like to display a list of times and two radio buttons next to them. Ex: Item1 ( ) This (o) That Item2 ( ) This (o) That Item3 (o) This ( ) That I tried with the Dynamic Appearance but it doesn't allow radio buttons. My feeling is that I should draw everything myself, meaning the radio buttons but also have to create and handle OnChange, OnSelect events to record them. Or should I find a way to have three columns with ItemsN on the first, a radio button on the 2nd, and another one on the 3rd? Or any way to get a ComboBox in the TListView item? Thanks for any help Steve

Using FMX development ios app, how to add universal link function?

Anyone else also having some problems with the OpenTools API when trying to get a list of Forms and DataModules from the current project? What I do is loop over all modules in my ActiveProject. Next I check if all of the IOTAModuleInfo.ModuleType are in [ omtForm. omtDataModule ]. I thought that would only be true for forms / datamodules. Sadly ... it seems to be the case for Units as well. So I had to resort to checking the FormName and DesignClass properties instead. for lcv := 0 to Pred( GetActiveProject.GetModuleCount ) do begin aModuleInfo := GetActiveProject.GetModule( lcv ); {$IFDEF CODESITE} CodeSite.SendString( 'aModuleInfo.FormName' , aModuleInfo.FormName ); CodeSite.SendString( 'aModuleInfo.DesignClass', aModuleInfo.DesignClass ); {$ENDIF} { Apparently this also returns us units and other stuff. Checking on the ModuleType doesn't seem to work, since it always returned 0, so I had to check for the FormName and D
