Happy Delphi coding year to all! How would be 2015 like for our little rodents? Due to popular request of several users of mORMot, we identified and designed some feature requests dedicated to BigData process. http://blog.synopse.info/post/2014/12/31/The-future-of-mORMot-is-BigData

What's the deal with SynEdit? What is the better branch for XE+?

From our fearless leader, a year ago: "In January, the Google+ Delphi Developers Community will have it's one year anniversary. With 2400 members, as well as 300+ members in the Delphi iOS & Android Community and the Delphi Component Directory, I really appreciate and enjoy the posts and discussions about my favorite tool!"  -- Lars Forsdal With nearly twice the members, I'd say it has been a good year!

Is there an tool that would register (optional) editor for .Caption property (For TLabel etc) that would allow me easily to edit multi-line captions. or I just have not found sane way to do them :D Would be cool if it also would set the WordWrap and autosize properties also, and maybe height... It would be sweet...

Hi, I am getting the following error when compiling my project to IOS device **********************************   file not found: /System/Library/Frameworks/SystemConfiguration.framework/SystemConfigurationld: file not found: /System/Library/Frameworks/SystemConfiguration.framework/SystemConfiguration *********************************** I have already applied the hot fix https://forums.embarcadero.com/thread.jspa?threadID=109979 Just to test I created a simple form project and it did compile and deployed.

Question of the Day: Under what circumstances might a simple string assignment -- assigning one string variable to another -- cause an access violation?

I read in a old release note "The Win32 SOAP server support generates the older RPC|Encoded style WebServices. If you want a document/literal service or a service of any other WS-I compliant style, you should build your SOAP server using Delphi Prism, which supports the SOAP specifications that are supported by the .NET framework, including WS-I compliant styles." So what's Rad Studio Soap framework for, since it's not possible to develop Interoperable Web Services? Would not be time for embarcadero to fully support Soap interoperability? With C++ Builder, would be possible to write a WS-I compliant soap service with gsoap, but i think that is poor for a product that presents itself as a top-level ide do not cover basic functionalities such this.

How can I change font & face color properties of the delete button at runtime( TListview)?

Something safe for New Year's Eve :) Jan Horn wrote this, December the 29th in 2001! Just add Variants to the uses clause in the .dpr file to get past the "NULL not found" error. Someone should port this to FireMonkey :) Update: Upon trying to find Jan's current whereabouts, I sadly learned that Jan Horn no longer is among us.  May he rest in peace, and be remembered fondly. http://www.sulaco.co.za/news_in_loving_memory_of_jan_horn.htm #opengl     #sourcecode   http://www.sulaco.co.za/opengl_project_fireworks.htm

FireMonkey's TOpenDialog on OSX seems buggy. The file listing isn't being drawn properly. Sometimes it's blank, despite the scroll bar indicating that there are many items. Scrolling around would exhibit drawing issues as well. Anyone else experiencing this issue? I'm using Delphi XE7 Upd1 - the program is running on OSX 10.9 I also noticed the bottom corners are not rounded.

It seems that FireMonkey's TForm has sharp bottom corners on OSX. Native OSX applications normally have rounded corners on all the four corners. How can I make TForm's bottom corners rounded?

I have custom Panel-component on my hands, I've done some enhancements to it (after inherited it), now I would need to have kind of functionality to detect when the mouse enters and leaves certain area of the component. I would like to change mouse cursor while user covers on the Caption I've drawn, if component is at certain state. Any ideas in what component to look for help, I tried to look on the VCL but did not happen to find any easy way to get mouse movements on the Component. Any pointers where to look from VCL, JVCL or some other publicly available source. have not done too much Custom component development, so any help is going to make my (second) day on this ;)

How to Display Menu Item Hints in Delphi Applications (Revisited) http://capecodgunny.blogspot.com/2014/12/how-to-display-menu-item-hints-in.html

Hi, I just updated DDL (src,demo, & wiki). The new update include: +BugFix for instruction decoding. +New BeginHooks/EndHooks functions to speed up hooking engine when hooking a lot of functions. +Updating Wiki pages for v2. https://code.google.com/p/delphi-detours-library/ https://code.google.com/p/delphi-detours-library

Hi guys. I'm trying to solve an odd problem with PNG components in a DLL expert, and I'm stuck. Any ideas? Details are: I've got a couple of bug reports for the Bookmarks plugin that when PngComponents ( http://cc.embarcadero.com/item/26127 ) are installed in XE2, trying to do something like (at designtime) load a PNG file in the a TPngBitBtn's PngImage property fails with an exception "Invalid graphic format". I can reproduce this, and it works fine when the plugin is not installed, so having the expert present is definitely the cause. According to one of the bug reports it doesn't happen in other IDE versions, just XE2. Debugging it under the IDE itself doesn't help - the call stack is: [20FE00D4]{designide160.bpl} PicEdit.TGraphicProperty.Edit (Line 272, "PicEdit.pas" + 10) + $12 [20878DB6]{coreide160.bpl} PropInsp.TPropertyInspector.PropListEditDblClick (Line 871, "PropInsp.pas" + 18) + $12 [2111DA0D]{vclide160.bpl} IDEInspListB...

I've a VM with many Delphi versions and want to clean up space from %ProgramData% to install more. I think somewhere in the comments it was mentioned what to delete from %ProgramData% to lessen the disk space used by Delphi installations. But I cannot find it searching either from plus.google.com itself, or using site: plus.google.com in Google Search. The VM is on an SSD, and the GUID directories there total to about 50 gigabytes. So any reminder what I can delete there would be much appreciated (:

A Backup Horror Story My second job (starting 1992) was for a company named Falcon Information Services, and my task was to rewrite a DOS based technical analysis program written in TP - for TPW for Windows.  Incidentally, my first development task ever for Windows. It was a small company, only 15 people, but with a significant market share in the financial market, and it was an awesome place to work. One day, my boss told me the story of the backup system they bought a few years before I started.  At the time, their backbone data delivery was all done on Unix (Solaris), and the operations machine was the development machine as well.  So, one day, they have a discussion: "Perhaps we should get a backup system? We are a bit vulnerable".  So, they bought a high end backup system, installed it, and made a full disk backup. "We should try a restore too, so that we know that it works". They did, and it didn't.  It was Friday evening, and the disk partitions were all...

OK, for a sometimes, part-time exploration of Android on XE7, any recommendations on a cheap tablet? Don't need lots of capabilities, just a reality check. UPDATE: I am told that in future, OS updates will require a device with 2GB RAM. If that is true, it puts another spin on the choices -- basically that a lesser one is a snapshot of history, so needs to be very cheap.

Hey guys, I was just wondering what would be the best approach of having multiple screens (forms) on a mobile app, that we can interchange with and have global procedures and variables, instead of using tabs? My app connects to the server and then downloads the database, but I am giving people the option to either have it local or accessed via the cloud, then after access is confirmed, the form display the results of the database on the 3rd screen. Only on the 3rd screen I am going to use tabs to have different means to search the database. So basically there is 3 different screens for now (login/signup, Option to download DB or access via cloud and the database results screen), what would be the easiest way to implement multiple screens(forms) and have the data between them interchangeable and also have global vars and procedures?

Are there any Delphi developers considering, or who would consider, moving to New Zealand ? Fancy spending your next Christmas having a BBQ on the beach ?  :) It's not only a beautiful country but also a great place to live. I work for one of NZ's largest and most respected IT companies and we have a need for a senior Delphi developer to be based in Auckland.  Initially the role will involve maintaining and enhancing legacy Delphi applications (5/7) but you will be expected to also develop your .Net and mobile skills, among others. The role is highly autonomous, working directly with clients and some time will be spent on site with travel outside of Auckland being involved.  As a result we need someone who is not only technically proficient but also professional, presentable and articulate. There are various options for obtaining the right to live and work in NZ, especially for high skilled migrants such as developers who are in high demand here.  I myself am originally from th...

Next OTA question: Is there a way to get the name of the method the cursor is in? I saw some plugins (like Castalia) showing that in some toolbars - or is that done by some custom pas parser?

Does anyone know how I can run the selected project with the OTA? I found the interface to compile it but not for running it. Edit: to clarify - I don't want to run the project under the debugger if possible.

There have not been much of the Talk of MemoryManagers lately, did quick search and there was even new contender. None of them seems to be in very active development tough. Ones that have been looking are : - FastMM (No signs of the Version 5) - ScaleMM - Interesting (two versions) - SynScaleMM - Fork of the previous - SapMM - Just found out about this, but tries to tackle multithreading issue. (What did I miss???) Someone using other than FastMM 4.xx in production?

Hi all, anybody knows if exist a llrp component for delphi ?

TurboPower SysTools version which supports Delphi XE7..?

Recently I've ported a huge chunk of code form C++ to Delphi. The code is full with pointers. Despite project compiling and kind of working, I'm seeing some weird results from time to time, which leads me to think there might be bugs with pointer handling - I've already found a few. The problem is that they are really hard to track down. Maybe you have some tips, for such cases:   var a: PSingle;   GetMem(a, SizeOf(Single));   a^ := 1.1;   someFunc(@a);// In the example, there's erroneous @ used. Worst of all program does not crash, just deals with that erroneous data and keeps running. How do you track down pointer bugs like these?

XE4 menu items not displaying hints. I never noticed this before but hints do not display when I hover over menu items. I'm running XE4. Hints are working just fine for all other components.

Many of you were asking for some online demos of Thinfinity VirtualUI. We've just finished setting up two applications for you to try. The first one is the famous "Fish Facts" in two flavors, basic UI virtualization and   browser and web resources integration. The second one is a nice open source .NET application that allows you to manage your personal finances.  To see the demos you have to go to the VirtualUI's web page in our web site: http://www.cybelesoft.com/thinfinity/virtualui/   I would appreciate very much your feedback, specially regarding the performance.

Dec 31st: Last Chance to Upgrade to XE7 from XE2 ** DO I UPGRADE TO XE7 BEFORE DEC 31? ** Talking strictly upgrading from XE2 PRO > XE7 PRO (not using FireDAC or Mobile Add-On), the upgrade price is $570. The new-user price is $1039 (+82%).  XE8 is right around the corner and it could be as soon as mid-April 2015 for it's release.  If I upgrade now for $570, that will ensure that I can get XE8 for $570. Assuming it's the same price.  If I don't upgrade now, I will need to pay the full price of XE8 for $1039. Assuming it's the same price.  ** Edit 5:12pm GMT-8 ** In other words.. it appears that XE8 will cost me $1140, if I upgrade to XE7 now and then XE8 later. - it could only cost me $1040 ($100 less), if I wait and purchase XE8 at the new-user price (assuming it's the same cost as XE7) Weird that it could actually cost me $100 less to wait and pay the new-user price for XE8. ** I don't suspect I'll be using FMX anytime soon, as my project is 100% VCL a...

I'm looking at doing a Live Streaming a video feed. The two options I am currently considering are www.LiveStream.com and www.LiveLens.com .

Which account would you find less objectionable to use to view a live video event you found interesting?

We announced today the release of Thinfinity® VirtualUI™ v1.0. Thanks to everyone, specially those of you that actively collaborated to get this amazing piece of software! For the rest of you that still didn't realise what you can do with VirtualUI, I encourage you not only to try it out but adopt it right away, leaving your Windows application VirtualUI-ready. Why? * It gets converted into a HTML5 multi-user, multi-instance application, with just including a unit to the uses clause. * When you run the application as usual, the added unit is just dead code, so it still will run as a normal Windows application.  * It is absolutely free for you! Your application gets transformed into a dual-platform Windows/HTML5 with new multi-user multi-instances capabilities by just dedicating a few minutes of your time. * And for few bucks, you can not only take you app to the web, but do all kind of integrations you can imagine with other web resources and applications.  I just hope that everyon...

My ISAPI/Datasnap nightmare continues.   As you know with MVC 5 & Identity table structures got changed . Login credentials are now saved to ASPNetUsers table. Now here is the problem. Earlier  important login validation fields where Password nvarchar(128) & PasswordSalt nvarchar(128) in table aspnet_Membership . Now with asp.net identity its in table AspNetUsers and fields are PasswordHash nvarchar(max)and SecurityStamp  nvarchar(max). Whenever my delphi isapi server does select  statement on fields that are of nvarchar(max) it throws 500 error. Question is why do we need nvarchar(max) for these fields and why is ISAPI not liking nvarchar(max) ?? Thanks.

Hi Guys,  I have a small question about Delphi and Memory Use. Maybe someone can explain to me. For the example class: TPerson = class   name: string;   Phone: string end; I will have about 4000 instances of this class; I need a method called GetNamePhone to return name+phone. My question is: If I include this method in the class, how much memory will be necessary to store these 4000 instances ? 1pointer for each instance or only one pointer to all instances ?

I'm trying to do something I guess I have never tried before, and so far, am feeling stupid. What I want to do is pass any of three or four different types of TFields (TIntegerField, TFloadField, and TStringField will be primary) as a parameter in a method call. So far, I have not found a workable declaration for the parameter.  I would have thought it a fairly obvious thing to do, but have turned up nothing useful on Google, either. I did find an example from Marco's Mastering Delphi 7, where I see (Sender: TField). However, when I tried (AField: TField) in my own code, the compiler complained. Perhaps something in XE7 I haven't puzzled out?

What I would like to receive from Delphi on xmas :) I strongly believe those features would make Delphi a better language. I'm not a C guru, but I've used those features in small C programs I've written and found them extremely useful. Specially, when variable can be declared anywhere - that, in my opinion, makes program much more readable as I don't need to scroll up to see what type of variable it is. Anyway, if anything of this is implemented, I would consider that my SA money is well spent. program delphi_xmas; // bitfields in records. Extremely useful when dealing with interfaces to C libraries // yes, I know they can be "implemented" in Delphi, but those implementations are not nice type   TBitRec = record   field1: integer:2;   field2: integer:1;  end;  // variable number of parameters procedure foo(...); begin   // possibility to identify function/procedure being executed (taken from C)   WriteLn(Format('%s(): start', [__func__]);   // ability ...

Would one of you fine people who knows C be willing to do me a favor?   I have a *.h file that I've converted to be a *.pas file, but for the life of me, I can't make it work.   Would any of you be willing to take a look at what I've done?  It's not very big, maybe a dozen functions.  It's a bit ugly with lots of *Char, but it shouldn't be too hard. If anyone can help, I'd be much obliged.

For a (standard) windows application, is there any way to get informed when (a) the screen size changes (mainly interested in vertical height change), and (b) the menu UI changes (such change in font, size of font)

If you are using Delphi XE2, keep in mind your "upgrade window" ends December 31st. After December 31st, you'll need to pay full price for a license. If you upgrade to XE7, you can consider maintenance (particularly if you are into mobile) or taking advantage of the recharge program in the future.

Just got a Delphi survey "why haven't you upgraded" and there was actually a "don't use it any more" option. That's been missing in the past. Although the "what percentage of new development is VCL/FM?headless" still had to add to 100%, even though in my case there is a GUI but it's HTML5 and C... and the back end is C++/PHP/Python. I miss Delphi. It would be really handy if Delphi did what I needed, but it doesn't and there's no real prospect that it will. C++ is full of tricks for naive idiots, where it has the feature but it doesn't work. "exceptions'... that mostly work, but you can't get a stack trace and it's up to whoever throws it to decide whether to give you more information than "something bad happened", and ideally they will actually throw an exception rather than, say, an integer. Or NULL. The C++ Frequently Questioned Answers (FQA) is an essential tool. http://yosefk.com/c++fqa/

Slap head moment! I finally fixed a bug I had in my code...some old code from years ago... Silly me,,,the code caused a stack overflow under certain circumstances ...so simple once I realised...the code ...I was a bit lazy at the time...I wanted a procedure to be repeated as soon as it was finished...so I was calling the procedure again inside the procedure..the stack overflow occured if that was done over about 780 times in a row....thats go to be one of those WTF coding examples , LOL :)

Has anybody experienced that when testing a #tDictionary key the returned value is incorrect (meaning, two different values have a key collision)? My tDictionary has an estimated number of over 6k collisions, meaning that after inserting all values I get about 17k results when iterating over the available keys, but I should get 23k. The key is basically a string made of two IP sockets (IPAddress A, Port A, IP Address B, Port B, separated by dashes), so it's not that short. Maybe I'm doing something wrong here. Is tDictionary supposed to have key collisions, and if so, how do I insert values that can be retrieved afterwards?

For Delphi newbies (who are also new to programming in general), is TStringList a suitable class for simple data management? I mean, it's pretty simple to explain (and understand) how to put a TStringList member in the form's private section, and then put Create + LoadFromFile in OnCreate ,  and SaveToFile + Free in OnClose . After that you can easily play with the Values property to get and set various data.  (The "Name=Value" structure if the file is pretty easy to understand too). Right now I cannot think of any simpler way to just load and save data directly from an application.  Any other suggestions?

#BEEP based TML/SIDEX SDK works with #android and #Java. I just got a #Delphi XE7. Should work as well, because it's based on NDK. A peer-to-peer communication layer with multireply and single port asynchronous messages will sure bring the communication of apps to the next level.

Hi. I've got a problem with oracle 12 data base client drivers for Embarcadero XE7. When i trying connect to DB by TSQLConnection control i'm always get an error : "TDBXError: DBX Error: Driver could not be properly initialized. Client library may be missing, not installed properly, of the wrong version, or the driver may be missing from the system path". FireDAC connection give me: [FireDAC][Phys][Ora]-1309. OCI is not properly installed on this machine (NOE1/INIT) error, but oracle client was installed by oracle installator, installacion completed correctly ("Oracle clent" was installed) Please help, any thoughts!!!

Just getting my toes wet with XE7, and have it in mind to use a class constructor in a situation where I want to contain some standard values as properties of the class. Clearly, I have failed to understand something in the workings of class constructors. Given this code, am I chasing something impossible? type   TPrintColors = class   strict private     FExFlightShade: TColor;     FExGraphBarColor: TColor;   public     class constructor Create;     class destructor Destroy;     property ExFlightShade: TColor read FExFlightShade write FExFlightShade;     property ExGraphBarColor: TColor read FExGraphBarColor write FExGraphBarColor;   end;   implementation   const   FlightShadeColor = $00F1D9C5;   HeaderShadeColor = $00CCFFFF; class constructor TPrintColors.Create; begin   FExFlightShade := FlightShadeColor;   FExGraphBarColorRadio := GraphBarColorRadio; end;   The compiler complains that the field members are not accessible. And if they are made class vars, then they cannot be fields f...

hi guys, i'm having a problem with Bitmap.LoadFromStream. I load images from rss feeds and with lollipop, this is now broken :-( i saw a workaround to save the images but thats unrealistic for a news app that simply loads images from a URL. Please can someone help me? thanks  #loadfromstream

FireDAC Date Handling - FireDAC Date Mystery Part II As it turns out, the mystery was not fully solved. After adding map rules (see old post) to FireDAC for how to handle dtTime and dtDate, I removed the old ADO special case handling and just did Result := FieldByName(FieldName).AsDateTime; Which worked well - or - so I thought.  I had done all my testing on machines that had the SQL Server Native Client installed, and it showed no problems. But - when I ran on a machine without SQLNCLI installed, the date format issue reared it's ugly head again. So - this is the "final" workaround which so far appears to handle every date/time format that I have tossed at it. function TPSDRecordset.GetAsDateTime(const FieldName: string): TDateTime; var   F: TField;   s: String; begin     F := FieldByName(FieldName);     try     case F.DataType of       ftDateTime: Result := F.AsDateTime;       ftTime: Result := StrToTime(F.AsString);       ftDate: Result := StrToDate(F.AsString);       ...

My daily - what? hourly! - experience with the IDE:

Does anyone have issues with XE7 (for it happened with and without update 1) where you are unable to compile or clean because somehow the debugger did not properly release the binary? (compiler cannot create the binary and the clean says it does not have access to the file). Only possibility I have right now is to restart the IDE a dozen times each day. Since I did not find a pattern when it happens I am looking for more people experiencing this problem. This is on Windows 8.1.

I clicked the "Delete Invalid Paths" button and totally messed up the Library paths on my XE4.  I think have re-built it correctly but I'm not 100% sure. Will you please have a look at the below list and please tell me if I'm missing something.

Anyone using TMS Component Pack? I am having a major issue trying to use the ADVSmothTabPager. I can create a new project, add a tab control, save the project and close it. But when I reload the project the tab control loads but I get an error saying it can't find the class TADVSmoothTabPage, which is declared in the same file as the main tab control which does load. I have tried everything including moving the PAS file into the project folder and that doesn't help. I need to edit an older project that contains one of these controls and this is keeping me from doing such. Tanks, Jim

Playing with DataSnap server I found something strange. A basic (TCP/IP, EchoString) DataSnap server for FMX do not let me add a non-Windows platform. So I've created a new FMX application and add the ServerContainer and ServerMethods units, it compile and work fine on OSX But for iOS and Android the compiler report that Datasnap is only for (Android, iOSDevice, Win32, OSX32, iOSSimulator, Win64)...ok and then ?! :D

Any way to register my XE7 key without installing Delphi? Kinda stupid to have to install XE7 just to register and then patch it, rather than just getting the latest ISO...

Does anyone here use os has tried the Chart ocx component from ComponentOne (formerly 'Olectra Chart`)? It works on the development computer but crashes on the test machine with the message "can't find the entry point of ippsSwapBytes_64u_l_ldx ..." (I discovered that this is a deprecated intel function for converting big endian little endian, have no idea why it's in their code). (using XE7 on a 32 bits program with the 32 bits version of ocx) I've installed the ocx with the setup, C1 docs says it's the only file needed. (C1 doesn't officially support Delphi, we're using it because old version worked very well on the old D7 code - it was supported back then)

Fellow Delphi developers, We are extremely happy and honored to celebrate HelpNDoc's 10 years anniversary: HelpNDoc version 1.0 was released on December of 2004 and we still can't believe how far it has evolved, and how popular and essential it is today for a constantly growing number of users. Read more to learn how to benefit from a 60% discount for 24 hours only! http://www.helpndoc.com/news/2014-12-09-helpndoc-10-years-old And if HelpNDoc is still alive today, it is because many believed in it, talked about it, sent us encouragements, suggestions, bug reports, wish lists... and bought licenses: we can't thank them enough for their continued support throughout the years! It was extremely fun and rewarding to develop and support HelpNDoc for the last 10 years. It was also challenging at times to fight irritating bugs and implement advanced features while making sure we didn't add too much complexity. And if we had to pick the one thing which helped us move forward and...
