It's happened... I have a new job, and some of the code is worth of Nick Hodges commentary:     if Data[i] in [' ', '|'] then     begin       delete(result, i, 1);       insert('|', result, i);       Exit;     end; (bonus: this is in Delphi 2010 so I found it via the "widechar reduced to byte in set expressions" warning) The good news is that because it's a vaguely recent Delphi I can start using OmniThreadLibrary again! We have threading, and threading issues, and a willingness to try OTL to avoid writing our own. Exciting!

Hi, When I try to deploy a Delphi XE4 app to my Mac, it says "wrapper init failed". Everything is up, restarted the PA server, but still no luck. OSX applications do deploy and run, btw. Anyone?

If anyone here is skilled in the use of VirtualStringTree, and willing to answer some questions from time to time, I would appreciate hearing from you. I am working my way into it, and documenting, as I go, the many things which have given me difficulty and which are not discussed in the available tutorials. I intend to offer the resulting document to the project.

Hi all, I'm still thinking about XE4 upgrade. I would be grateful if any help us with examples of the usage of iOS and bluetooth. Is there a way to know more about the full capabilities of XE4? The examples of the usage of the camera are ok, but in practice we need more and more information. I am really Delphi fan but for making an investment decision I'm not influenced by emotions. Bulgaria is a poor country, and the cost of the upgrade for me is really serious. My ultimate goal is to make libraries(or application) for bluetooth communication with some external devices and I will be really happy if this happens with Delphi. If there is not such an example - at least is there a way? How to search for devices, how to open the connection? The connection is with streams or not? Sorry about my poor English. :)

Thank you to PACKT Publishing that sent to me the new book about ZeroMQ ( goo.gl/J3QFz ) asking for a review. I'll write it asap on my blog with some C samples translated to Delphi for the most common pattern (REQ/REP, PUB/SUB, PULL/PUSH)

Is there a tool to get rid of the With statements in units?  I'm doing it manually now, but it sure is tedious.   Being new at this job, I feel the code would be easier to understand and debug without WITHs.   Also, With might be going away.

Does anyone know why TApplication.HintShortPause is 0 by default (in XE and newer) although documentation says it's 50 to avoid flicker (which I have because it's 0)?

I formerly used VGScene, after embarcadero bought this project I am no longer able to maintain my project GUI the way i wanted most because I cannot use QuantumGrid together with firemonkey (I used a controll called TNonVGLayout before) + a few other VCL's. i need a way to put a PNG image with alphacolors in a button, I mainly use Raize components today, I do not wish to put the images in a imagelist, so how do i solve this little issue?

Hi All, I use Delphi on a French localized Windows version. When installing, Delphi installer ask for extra languages I want to install. After installation, I'm able to switch the IDE from the default language (French here) to the English language using BdsSetLang utility provided by Embarcadero. It works perfactly except that the help files are still in the default language. My question is: How to switch the online help to English ? Thanks.

Hi All, can any one help me to restrict call onchange event of dataset while i do its post,first,next,locate etc operation?.

Lazy Delphi Builder 1.8.6.240 released. Lazy Delphi Builder - free automated build tool/component installer. What's new: * Delphi XE4 support. And just in case if it will be released in a next few months – I have added Delphi XE5 support =) * Presets. Create presets for output directories, build options, environment variables, and other.. * LazyDBP and ini files format was changed. From now, lists will be saved as plain lists, without numbers as id. And, btw, all the settings from now are stored in the Data subdirectory. New profile format (v2) is not backward compatible with previous (v1), but you can still save file in previous format using Save as dialog. * Multiple expressions support in tree’s filter (via semicolon “;”) * Call any custom bat or exe file instead of dcc32.exe. (see item # 9 in changelog) * Added Delphi version autodetection algorythm from the filename (see. Check Wizard) * New editor for compiler defines. * Many improvements and fixes (see the full list in chang...

I know that Git is a fairly popular DVCS in the Delphi community, so I thought this blog post may be of interest. The author, Pieter Hintjens, feels that branching in Git, which I think can be applied to other DVCS tools, is not a good idea, in fact, even harmful.  He also offers his C4 and PC3  processes as better ways to manage projects with Git. Side note: Pieter Hintjens is the the guy basically responsible for AMQP, WikiDot, and ZeroMQ. While perhaps coming off as a bit arrogant (see some of his interviews), he's definitely a very bright guy. http://hintjens.com/blog:24

Did anybod achieve to deploy a https based dbx servermethod client on an ios device? I could get it working on the simulator but not on the device with https. I have no problem however to make a simple https get request with TIdHTTP on the device. So it is not a general "indy and ssl is not working on an ios device-problem" but a "ssl and dbx server methods is not working on an ios device-problem".

WebFMX beta 3 is ready. You can download it from http://www.cybelesoft.com/downloads/webfmxsetup_0.9.3.1.exe This beta includes support for XE4, plus bug fixes. We also included an example page (SDK.html) that shows you how to use the Javascript API to integrate a remote FireMonkey application into an external website. Please don't forget to ask for your free developer license! We'll start sending these out as soon as we get to the final version. http://www.cybelesoft.com/webfmx

Has anyone figured out how to discover, in a TMS TAdvStringGrid (or descendant) event handler, how to know whether the ACol parameter represents the display context or the absolute context? Recent changes have affected numerous of my event handlers, and it's not intuitive, at least to me. Ideally, there would be a way to discover the answer in code, but failing that, I would settle, at this point, for a way to scan the TMS source and find the answer. I have also posted in the TMS Component User Group circle, but am desperate to find an answer.

I watched the webinar yesterday. All about how to create iphone apps and not a lot else. Guess what - ios not included in the pro edition - extra $499 or have to buy more expensive edition. Is the rest of it any change on XE3?

It seems to me that the general feeling in the Delphi community is that we would like the stability issues to be addressed before any more features are added. Has anybody considered trying to get the message through to Embarcadero in a slightly more formal manner? Perhaps, if we come together as a community, we can actually alter the course of Delphi a little. How about an open letter or petition signed by members of the community? Just a thought :)

As a followup to Bill Meyer 's recent post, I made a small poll to see what the "community" would really like to see. This is practical poll question, what would get you to buy a newer Delphi version? What would you like to see most and foremost, and would most have a use for? http://delphitools.info/2013/04/26/what-would-get-you-to-buy-a-newer-delphi-version/

I've finally managed to test one of the XE4 samples on my iPhone4S and I must say I'm a little shocked. For example, the iOSControls demo (C:\Users\Public\Documents\RAD Studio\11.0\Samples\FireMonkeyMobile\iOSControls) takes around 10 seconds to load. Once loaded, switching tabs has a noticeable delay the first time a tab is displayed. In addition, the animation is very slow and choppy. It's unsightly for controls like checkboxes, but almost unusable for memos and edits when the magnifying glass is displayed. I really want to start developing iOS apps, but I'm not sure that I can publish them if they behave this way. I'm not even sure that Apple will accept them in the app store :( Marco Cantù, please tell us that you are working hard to optimise the UI code.

OK, so as I am still on RAD Studio XE, I'd appreciate hearing from people why I ought to upgrade to XE4. All my work is, at present, on Windows.

Xe4 meeting in shenzhen 04/25/2013, Dear delphi expert ,Mr. Lee Wei

Why I don't like dotnet ? I use a great program to track time usage from www.manictime.com . Unfortunately it is written in Dotnet. Recent versions of it require Dotnet 4 that in turn require 728 MB of my harddisk space! So I use an older version with an older and smaller dotnet. I use it on a virtual machine and diskspace is limited. I could imagine a Delphi program would require a fraction of diskspace for the same functionality... :) http://www.manictime.com.

I installed XE 4 Architect (which should contain the mobile capabilities). I cannot see however any possibility to start a mobile project under File | New ... The installation support seems to have no idea why this could happen. Has anybody of you ever experienced such a problem?

I've made another post category: XE4 Issues - which is intended for discussing technical issues that you discover in XE4.   Note: Not for moaning and bitching - just for facts and workarounds.

My form is implementing some interface. Since TForm is derived from TComponent which implements IInterface without reference counting I'm creating my form with an owner which will take care of freeing the memory. But when it's doing it - it generates an AV. example   ISomeinterface = Interface   ['{04D066E2-8EE1-4344-883A-177AEC2A38E4}'] (...)   end;   TFInterfacedForm = class(TForm, ISomeInterface) (...)   end; var   SomeInterface: ISomeinterface; initialization   SomeInterface := TFInterfacedForm.Create(Application) as ISomeinterface; It generates AV on application closing. I'm using Delphi 7

Hi all ! I can't find an answer to the following question : Is there an interest to use var in an object declaration as parameter : Procedure GetResults(pID : Integer ; var pResults : TList ); vs Procedure GetResults(pID : Integer ; pResults : TList ); as objects are passed by ref anyway ? and does const has a meaning in object declarations ?

After having downloaded XE4 instant trial yesterday and playing a bit with it, today I had to go back to the real world and wanted to start Delphi XE: It showed me the registration window and I had to register again (I guess this bumped my registration count). Has anybody else experienced this, or is this something special on my machine ?

I just received the email below from JED Software. Basically it says that they have sold JSDialog pack to another company. The part I find interesting though is this: "Some may have noted that I recently pulled the QualityCentral client from my website for the same (and another) reason" Could this mean that Embarcadero might be using it as a base for a new (desperately needed) QualityCentral client? ----------- The XE4 version of JSDialog Pack will be released shortly, there is still some testing to be done against the XE4 release build.   Due to a change in personal circumstances, I have decided to sell the IP of JSDialog Pack to another third party vendor. Part of the deal includes me supporting their developers getting up to speed with the source code for JSDialog Pack as well as advising them on any support requests for six months. This six month period should also cover the release of XE5 by Embarcadero if they stick to the usual release cycle of September.   The buyer h...

GExperts for XE4 While waiting for the official release, here's my colleague Thorsten's compiled copy. No guarantees, but it works for me. I couldn't live without the "open file" dialog; assign to ctrl-U and make opening files easier.   https://www.dropbox.com/s/in8zzu6wynihp9x/GExpertsRSXE4.zip     in the registry, under HKCU\Software\Emb..\BDS\11.0\Experts   you need to add a new string called "GExperts" with path and filename of that DLL as value.   Important: don't put the file anywhere near the Embarcadero program files directories, or your Delphi will fail to start because it thinks the DLL is for hacking. Yes, we all know, its a pretty dumb check. https://www.dropbox.com/s/in8zzu6wynihp9x/GExpertsRSXE4.zip

I got a chuckle out of this comment in an XE4 press release: You are advised to rewrite code that uses WITH as this is likely to be removed in future versions. I can see the benefit in enforcing this, as I have bumped into so many scope errors caused by over-zealous WITH usage over the years… Today WITH, tomorrow FreeAndNil :-)

Hi, I’m trying to solve the following problem using Generics: I need to implement a collection (say List or DynArray) of Generic Dynamic Sub-Arrays, so that each Sub-Array can hold data of different type.

If anyone here has experience with the use of the JCL MAPI components, I would appreciate some assistance. I found on Stack Overflow a MAPI.SendMail class which seems very useful, but when the message body is in HTML, the underlying JCL code puts the HTML in an attachment, not in the body of the e-mail, where I need it. This appears to be the standard JCL approach to that issue, unless there is some property I have missed?

Another interesting potential stumbling block for XE4. "To keep up with the notion of eliminating pointers, the new compiler requires an explicit style of marshalling data to/from external APIs and libraries. This can be accomplished by using the high-level marshalling API TMarshaller: http://docwiki.embarcadero.com/Libraries/XE4/en/System.SysUtils.TMarshaller   or the low-level TMarshal: http://docwiki.embarcadero.com/Libraries/XE4/en/System.TMarshal " I wonder if this is limited to the iOS compiler, or if it applies to x86/x64 too?

Differences between Delphi Desktop Compilers and Delphi Mobile Compilers (Yanked from the What's new page) The two Delphi mobile compilers (DCCIOSARM and DCCIOS32) are quite different from the Delphi desktop compilers (DCC32, DCC64, DCCOSX). The mobile compilers can be considered a "Next Generation" of the Delphi language, and the mobile platform is a new step in the continuing evolution of the Delphi language. Keep in mind, however, that the language differences typically are not related to platform differences. To summarize: - No inline assembly is supported on iOS, but four atomic intrinsic functions are supported by the Delphi mobile compiilers - COM is not supported - Seven of the older string types are not supported: AnsiString WideString AnsiChar and PAnsiChar PWideChar OpenString ShortString Strings are: - Immutable (constant), so you cannot index into a string as an array and manipulate the characters in a string - If you attempt to modify a string, the Delphi mo...

(in MS SQL Server 2008+) After lots of searching I found at least a query to find #slow #compile queries (with high cpu and memory usage): http://www.sqlskills.com/blogs/jonathan/identifying-high-compile-time-statements-from-the-plan-cache/ Together with a "clear all cache" sql I could reproduce and optimize the slow query: DBCC FREEPROCCACHE; DBCC DROPCLEANBUFFERS; DBCC FREESESSIONCACHE; DBCC FREESYSTEMCACHE ('ALL'); It turns out that you should not use (many) "view in view in view in view" :) After combining all views into one big sql (with sub select in sub select in sub join etc) I got from "10s + 81Mb" to "1.2s + 17Mb" compile time and memory usage!  Wow, is Sql Server so in-efficient in compiling subsubsubsub views?  http://www.sqlskills.com/blogs/jonathan/identifying-high-compile-time-statements-from-the-plan-cache/

http://blog.synopse.info/tag/weak%20pointers Just to point out some blog posts of interest about the ARC memory model, weak pointers and how it works, even before Delphi XE4 on iOS.  Note that IMHO zeroing weak pointers may not be there. And I wonder about performance issues (if it XE4 implementation was not enhanced in regard to what was already present in XE3 RTL for handling weak references). http://blog.synopse.info/tag/weak%20pointers

I am using Delphi 2007 and the helpfile is not in sync with the GUI. From the help file when I press help button in this dialog:    "Code completion  Displays a list of properties, methods and events when you enter a class name followed by a period in the Code Editor. You can then select an item and press ENTER to add it to your code.  If this option is not checked, you can still invoke code completion by pressing CTRL+SPACE. The default value is On (checked).    Error Insight  Underlines invalid code and HTML in red. Positioning the cursor over invalid text displays a tooltip window containing the probable cause of the error. The default value is On (checked).    Code Template Completion  Automatically adds a code template when you type a token that starts a template and press TAB. The default value is On (checked).    Auto Complete Templates  Invokes code template completion when you press SPACE after you begin an existing template. When this option is disabled, you must press T...

PIXEL_BIT_COUNT(n)    ((n) shl 16) const    PixelType_Mono8 = PIXEL_MONO or PIXEL_BIT_COUNT(8) or $0001 Could you tell me how to define PIXEL_BIT_COUNT ?

For rumors, rants and those truly far off topic things I hate to be a "forum nazi" but I really want this Community to be about the Delphi toolkit, and the hows and whats of writing code with it. So - not to deny your right to express yourselves freely, I suggest everyone that has an interest in the political and managerial side of the product, join up with Unit Number Five! Edit: Do you guys find this an acceptable solution, or would you rather have the rumors and rants here in Delphi Developers? Comments would be appreciated!

Hello. I am about to polish and enhance the UI of my memory profiler ( http://ddobjects.de/dddebug ) as some testers and reviewers said it's not very intuitive (many functions are hidden behind popup menus etc). Therefore I am looking for some nice icons which are free for commercial use. As I am distributing the source code, the license should allow me to distribute those icons (of course credit will be given). Does anyone know a good and reliable source for such icons? Thanks in advance :)

New post: "Sneak peek to simple integration between #DMVCFramework and #DORM" http://www.danieleteti.it/2013/04/18/sneak-peek-to-simple-integration-between-dmvcframework-and-dorm/ http://www.danieleteti.it/2013/04/18/sneak-peek-to-simple-integration-between-dmvcframework-and-dorm/

Here's why I always always always put a begin...end around every statement.  I just had to fix a bad, hard to see bug like the following..... if SomeBoolean then begin ... end else   if Something then   begin   end else     ErrorMessage := 'This is an error';     Inc(ErrorCount); Hard to spot.

A request to all Spring4d users: I need some feedback about the work that has been done in the refactoring branch. It affects the collections and moves most "extension" methods from the interface types to the Enumerable type (that you can access from IEnumerable .AsEnumerable). It also introduces many new extension methods. What I need is the compilation time, binary size difference, used Delphi version and if possible the approximate number of specialized types (how many different TList and so on do you use) of your projects with both the trunk and the refactoring branch.

TDictionary ... why oh why doesn't myDict[x] := foobar; just call AddOrSet value, instead of forcing me to call Add for new values.
