When the mORMot (Delphi) developer meets the Brook (Free Pascal) developer - IMHO, both mORMot and Brook are the best  open source web frameworks for Delphi and FPC respectively, and this discussion lead to an argument between the developers of these two frameworks. http://synopse.info/forum/viewtopic.php?id=1762

Had a problem last week with D2007, where there were a few lines of code that had no blue dots after a build. They also would not accept breakpoints. Has anyone else encountered this? In the end, I retyped the code block, then commented out the old lines, and it worked, leaving me to believe that there was some undisplayed character in the source which caused the problem.

Hi Gurus, Does somebody knows a solution for Tims problem? http://stackoverflow.com/q/23907144?sgp=2

Perhaps a silly question: Does the History tab exist in XE6 Pro?  Mine's gone missing, in all projects, and since I didn't look for it until I needed it and I've only had XE6 for a few weeks, I don't know if it was there and is missing, or was just never there. The __history folders still exist, but the IDE tab doesn't.

ANN: HTML Report Library released! HRL is a template-based reporting library for Delphi, designed to generate reports using databases and XML. Templates are simple HTML files containing special tags, and output is pure HTML suitable for displaying in any browser and sending by mail (all of the graphics are directly integrated into the text, so when sending mail you don't have to attach pictures separately). HRL can be used in client applications to generate and view report inside the program, and in server applications or Web-servers. As a template language HRL uses widely known Mustache with some extensions. Library supports all versions of Delphi from Delphi 6 to Delphi XE6, and also supports Unicode for old non-unicode versions of Delphi using widestring. HRL fully supports Right-to-Left languages, including order of table columns and location of chart data. HRL supports major data-access components ( FireDac, IBX, UIB, DOA). Adapters for other libraries could be implemented ver

Hi Everyone. My name is Pawel Piotrowski, I'm living in Poland and I'm a delphi programmer since more then 15 years. I even developed a 3D Game Engine with delphi. That was fun. I'm currently running my own small software development company, and we are doing delphi programming for the most part. Not only delphi, but that is the main language we are using. If you like to know more, or if you need a delphi contractor, please see more at http://www.maxlogic.eu

A response from a Dinosaur... Originally shared by Michael Riley I am one of those Dinosaurs. I am a self-taught Delphi programmer (I actually started with Turbo Pascal 3). Until about two years ago my thought process was I must build everything I can by myself. I am One-Person Part-Time Micro ISV (OPPTMISV).  I have a library of approximately 80 Delphi/Pascal books. Google, SO and the web didn't exist when I started programming. It was a lonely and challenging place for individual programmers like me. To learn new concepts you spent hours in the book store looking for answers before buying yet another book that duplicated 90% of all the other books. There were also bulletin boards and newsgroups but the interaction was not instantaneous like it is today. Hell, finding like-minded and like-skillset people was a challenge in and of itself. I dare you to go one week with out googling for an answer. I bet you can't do it. :-) I'm a die-hard Delphi guy. I have a constant love-h

Ok guys, it's time to learn a little about FMX ... and French :) I was disapointed by the lacks of Drag&Drop support under Android, but I dig the FMX source code and found what's going on. My Execute.FMXBasedDragDrop unit is a crossplaform implementation of Drag&Drop for Android (and probably iOS, but I don't have an iPhone). All the explanation are in french, but the source code is english commented, you can find the sample projet on the bottom link of the page. http://lookinside.free.fr/delphi.php?FMXBasedDragDrop Conclusion: it would be great to have access to TCommonCustomForm.FMousePos and TCommonCustomForm.SetCaptured.

Delphi XE2: Nested Comments, I want them! I've had some troubles with nested "{" and "}" pairs aka curly-braces. Specifically, when I have a piece of code with an inline comment that I'd like to keep.... function ThisIsAFunction() begin    if (SomeFunction(Var1{used to use Var2})) then       DoSomething(); end; ... But in debugging, I decided to comment a line out in this function. However, nest curly-braces don't seem to work and the IDE/compiler complains... function ThisIsAFunction() begin {   if (SomeFunction(Var1{used to use Var2})) then       DoSomething();} end; Sometimes, I want to comment out a section of code and mark it..  {$REGION 'OldCode'} { function ThisIsAFunction() begin {   if (SomeFunction(Var1{used to use Var2})) then       DoSomething();} end; } {$ENDREGION} I always have to change my comments to "//" when I want to enclose them in "{".

Re-use of registered components and libraries Hi all. We're currently switching to a new version control system, and we're reconsidering the way we set up our Delphi projects. We routinely use a set of external components, like TMS, Raize, WPCubed, etc. Any developer will typically work on different projects, and each project can use different versions of those components, depending on when the product was last updated (some are so old they only need updating once every few years). Our problem is that, in order to be used at design time, a component needs to be registered in Delphi. After doing this, Delphi will try to load that component even when no project is loaded . I would prefer if components were only loaded when a project that references them is opened. This means we can't load one version of a component for one project, and a different version for another project.  We've circumvented this by installing the library components on a mapped drive (W:\Lib). When sw

OK, I am considering building a DLL in XE5 to be called from D2007, to solve a problem. It would involve using a non-visual component not available in D2007. Apart from the obvious Unicode issues, I also need access to data, as determined by the calling program. I am thinking that the safest solution may be to give the DLL its own connection, and pass in the query. Any thoughts?

Has anyone noticed Error Insight seems to be less buggy in XE6?  I still get erroneous red underlines sometimes, but in fewer places. For me, the red underlines that remain usually seem to be complaining a variable doesn't have something that belongs to TObject, eg Free or ClassName, but that's it - the rest seems to work.  It's actually been mildly useful once or twice!

Does anyone know the exact dcc parameters for rebuilding an RTL unit (System.Rtti.pas in my case) so that it is compatible with the ones shipped? (both release and debug would be nice) And yes I only changed the implementation part. I found this on SO ( http://stackoverflow.com/questions/4839532/recompiling-the-rtl-if-possible-then-how ) but the options did not work as I get the F2051 error (unit X was compiled with a different version of Y).

I'd like to talk with people using third-party components for Excel export. We're currently using Axolot, and have been unable to find solutions for some detail issues. We are switching to FlexCel, and I haven't discovered yet whether we will have solutions for the issues there.  I am particularly concerned with two things, at present: First, a means of inserting a graphic image without altering its size or aspect ratio. Second, a means of getting the column widths in linear units, rather than characters or fractions of a character.

I love IEnumerable (the Spring4D one, not the System.pas one ^^) and "record" helpers. Instead of writing a loop over the array returned from TRttiType.GetMethods figuring out those with the most arguments on the most derived class that match the passed arguments I could just chain Ordered, TakeWhile and Where for some badass "query" that returns the constructor(s) I want. How that is possible? Check this out: uses   Spring.Collections,   Rtti; type   TRttiMethodArrayHelper = record helper for TArray     function AsEnumerable: IEnumerable ;   end; function TRttiMethodArrayHelper.AsEnumerable: IEnumerable ; begin   Result := TCollections.Query (Self); end;

Hi All, I have a need to use .Net managed code in Delphi win32 application. I am currently using Delphi 2007. As far as I know, we cannot call managed code from within Windows Application written in Delphi. We can write wrapper in .Net to expose the managed part or make the .net managed code exposed to COM and call that COM dll. Does any one see any direct way to call .Net assembly without modifying any of its code in .Net? Does latest version of Delphi supports calling managed code for Win32 application ? Thanks in advance.

Hi Everyone, I'm a die-hard Delphi guy (aren't we all).  I've been programming in Delphi since Turbo Pascal 3. I did get burned out for about 8 years. I got back into Delphi programming about 2 1/2 years ago. I have a Love / Hate relationship with Delphi. Most of the time I love Delphi. I love learning new stuff about Delphi. I don't like learning the same thing over and over. So, this time when I came back to Delphi I started a blog. It's my little scratch pad of Delphi stuff. Why keep notes on paper when I can keep them in a blog for free.

I am missing the overlay icons, blame and all that cool stuff.

Is anyone still using the JCL's UnitVersioning functionality? Every JCL and JVCL unit registers itself to the JclUnitVersioning across module boundaries. The registered data contains the SVN revision and last commit date which can be used to show the data for every unit in an exception dialog. Well, it is broken and not only because all the SVN data (revision, date) is missing since the projects moved to GitHub. If you use DLLs that contain JCL/JVCL units and are loaded dynamically and not unloaded before the EXE's JclUnitVersioning finalization ran, you will get access violations. The code is only partly thread-safe what means it is not thread-safe. So loading such a DLL from a thread can cause a race condition. I had a look at the code and I don't see an easy way to get the current implementation to work without rewriting it. But why rewrite it if you can delete it. All the data is missing anyhow. So I see no point in fixing code that nobody would even find useful anymore

Has anyone seen a deadlock in unit initialization in a FMX app when using runtime packages? I can reproduce this in XE4 like so:  - New FMX app.  Make is 3D, have a 3D form.  - Project Options > Packages > Runtime Packages > All configurations (32-bit Windows platform) > Link with runtime packages - set to True Run the app.  About 50% of the time, you will get a deadlock with two threads, each in a method called by System.InitUnits. Here's the really weird thing (apart from it being two threads each init-ing units.)  InitUnits looks after the unit initialization code, ie calling whatever is in the initialization section.  The second time InitUnits is called, from a second thread this time, it has more units to loop through than before (152 vs 291.)  And, the unit that is causing the deadlock is - wait for it - Vcl.Controls.  Yes, VCL.  Why is that unit ever loaded in a brand new FMX app?

(IOS / Android)  I have an application and I need you to commence the background, from time to time perform a check on the DataSnap server and if needed, give a notification.  Already read in some places something about it however nothing helped me. The application is in the background for a few seconds and the OS gets it on "pause" and not turning the code I need.  How to solve this? Imagine a whatsapp chat or any program, it has to run in the background and give notifications for incoming messages.  thank you

Today i stumbled across something in the RTL I'd like to discuss. When writing routines and implement error handling, i prefer to not raise execptions if i have a resultvalue(like Bool), even if the parametervalidation runs into an unwanted value. I simply return False and exit. In procedures i do raise exceptions(no discussion about whether I should use a function with resultvalue here, just an example). As i used ForceDirectories i encountered an exception ("Unable to Create Directory"). A path was given(by userinput), and just the result(worked, did not work) was expected. However, looking into the function revealed, that it checked for it's parameter not being empty and otherwhise raising an exception(instead of just returning false): if APath = '' then begin   //raise exception end; So i thought at least just preventing empty Path variables to be passed fixes this problem. A path like this however: FooFolder\ raises the same exception. When stepping throu

There are people out there, trying to tell us that Delphi is an "old" language or lacks "important" Languagefeatures. As i started using UnrealEngine 4 some weeks ago, i started using C++ again. Haven't touched it for years(and i never used it extensively, so my knowledge is quite simple anyway). Today, a blogpost on the UnrealEngine 4 showed "range based for loops" which are part of C++11. So the C++ universe lived without a for in loop for such a long time? So basically, Delphi implemented a feature before it was part of C++? https://www.unrealengine.com/blog/ranged-based-for-loops https://www.unrealengine.com/blog/ranged-based-for-loops

Bad surprise of the day: SysUtils.TEncoding in XE2+ defaults to ANSI, while in XE it defaulted to UTF-8. Among other things this means that TStringList fails to load UTF-8 text files that don't have a BOM, which is very common nowadays. Wasn't ANSI already obsolete 10 years ago?

Hi Friends, I have created DLL using delphi 2007. But when i trying to register it using regsrv32 it returns error like "My.dll was loaded but the dllRegisterServer entry point was not found". is there anything i need to take care @ compile time? or i missed anything?

I need some advice with re-directing some WebService calls I make using Delphi XE. I know this isn't relevant to Delphi, but I need to transparently redirect my web service calls which are on the internet to a local server (with whaetever tech necessary) which will re-direct them to the real server and send back the results, without using a proxy, or any config on the client or source code changes on my client app (except for the webservice endpoint which is needless to say, dynamic).  Any ideas how I can achieve this?

Post "moved" from Delphi Component Directory Originally shared by Frank Duchna Hello everbody. Could someone help me on how i can store a password in an SQL database? Other Option would be to find out which user is connected to the database. I want to set up a rights-management within my Software to control which parts are used and to filter data from the database. Thanks in advance. Frank

The upcoming release of kbmMW Enterprise Edition also adds support for FastCGI! In fact your future kbmMW based sites will be able to combine any FastCGI enabled technology with kbmMWs own built in HTML handling, in one application. The attachments shows a standard PHPSQliteCMS ( http://phpsqlitecms.net/ ) installation being served by kbmMW. kbmMW on Windows will be able to spawn relevant FastCGI servers automatically. kbmMW on ALL platforms (including mobile) will be able to take advantage of any number of external FastCGI servers. This is the code required to setup kbmMW to act as a web server serving PHP pages: procedure TForm1.FormCreate(Sender: TObject); var    sd:TkbmMWHTTPFastCGIServiceDefinition;    sl:TkbmMWConnectionStringArray; begin sd:=TkbmMWHTTPFastCGIServiceDefinition(kbmMWServer1.RegisterService(TFastCGIHTTPService,false));      // Its possible to define a default file name if no file is      // referenced. As we define a PHP FastCGI site, index.pbp is      // typically

IDE Fix Pack 5.6 for XE6 is released. It not only adds supports for XE6 but also applies the Compiler Speed Pack to the Android compiler what means that I can now start my research about what takes that long in the Android compiler's compllvm.dll before it executes the slow Android linker. http://andy.jgknet.de/blog/2014/05/ide-fix-pack-5-6-for-xe6-released/

I have an application that make heavy use of TWebBrowser to show GoogleMaps. The problem is that the memory is not deallocated properly. I also notice that for each instance of TWebBrowser it starts new threads. Those are also left. It take CPU resources and memory. So how can close TWebBrowser instance properly, close threads and deallocate memory?

Off topic question, nothing to do with Delphi Does anyone know how to permanently remove an alias in PowerShell? The one that annoys me is wget alias for Invoke-WebRequest , hiding my Gnu32 wget installation in PowerShell V3. Remove-Item alias:\wget did only work for one session, restarting PowerShell and it's back.

The official documentation only says the built-in Extended type is 10 bytes on Win32 platform and 8 bytes on Win64 platform (Alias of Double).   But What's the size of the Extended type in the other platforms? (OSX, IOSARM, IOS32, ANDROID)? http://docwiki.embarcadero.com/Libraries/XE6/en/System.Extended http://docwiki.embarcadero.com/Libraries/XE6/en/System.Extended

Comment of the Day: // Hardcoded to Mitch's computer IP // Hopefully SMTP server is running here followed by an IP address as a string. Mitch hasn't worked here in three years.

Can someone please explain what the purpose of the HasWeakRef and a different array manager is in the System.Generics.Collections? If you look at the implementation of System.TypInfo.HasWeakRef it only returns True for tkMethod or a record/array that has a field of tkMethod. In such cases the list classes do not use Move but explicitly loop through the array and assign each element. What is the difference for tkMethod there as I always thought this is just a record of two pointers as defined in System.TMethod.

I wish type inference would not only work for arguments of the type T but also for (arguments of) generic types of T.

We're using a third-party dll provided by a hardware manufacturer, apparently the developers thought it's a great idea to show messages from dll in stead of just returning an error code. The problem: - dll calls MessageBoxA whenever it feels like, we don't know all cases in which it display a message, the application is a kiosk, therefore it's unacceptable Partial solution: - currently, using  https://code.google.com/p/delphi-detours-library/ we can intercept all calls to MessageBoxA and log them, however, ideally, we would want to hook just the call from the dll or somehow, figure out that the caller is the dll Any help is appreciated!

Two most annoying things when i find myself in a world with 4-5 IDEs as opposed to some years back when i had only one. 1. The debugger in Chrome/webkit uses F8 to "run" and F10 to step. Delphi uses F8 to step. Have to reload that page and really step this time. Argh! 2. Typing HTML code in a zen-editor. Why do i ALWAYS type "string" when i want to type "strong"? 3. Oh and all the various and different F3-search-models... that calls for a platform-independent-non-localizable world standard! NOW! IMHO. Happy coding!

Hi everyone! IDE plugins are a bit of a "black art" still, and then even more so when you get past the published plugin API into things that require hacking the IDE. I wrote this blog post yesterday - it's the first in a series on painting inside the code editor, something about which there is no material whatsoever anywhere on the internet. If you're interested in wizards/experts/plugins or even in a small insight into how the IDE works internally, you might find it interesting. http://itinerantdeveloper.blogspot.com/2014/05/mysteries-of-ide-plugins-painting-in.html

DevExpress is going to surprise us in the upcoming VCL 14.1 release! http://community.devexpress.com/blogs/ctodx/archive/2014/05/05/rad-studio-xe6-supported-with-devexpress-vcl.aspx

Hello,  I'm getting an error when my application terminated. Note: My project is DLL project and I'm using #Delphi #XE6 "EMonitorLockException" Object lock not owned Has anyone get this error before ?

Is Delphi XE6 the first Delphi which makes executables smaller than previous version? :) Below are file sizes for empty VCL and FireMonkey projects. VCL application is bigger as usual: XE5: 2 104 320 bytes XE6: 2 260 992 bytes But for FireMonkey Desktop Application the numbers are: XE5: 5 297 152 bytes XE6: 5 052 928 bytes

Janez Atmapuri Makovsek found some #XE6  array optimizations Inline declared setter and getter functions can yield up to six times the performance on one-dimensional arrays and up to four times the performance on 2D arrays, compared to XE5. Spotted at the EMBT forums. http://www.dewresearch.com/news/232-rad-studio-xe6-lo-and-behold

Just started to make our projects HighDPI aware - especially on Windows 8 tablets. From now on I'm going to refer to this as "Project Pandora" . Delphi is not really made for making HighDPI aware programs. Using DevExpress components already solved a lot of the potential trouble. But it is surprising how many components - even 1st party Delphi components - totally lack HighDPI awareness.
