New stable release of CnPack has been released -  http://www.cnpack.org/showdetail.php?id=764&lang=en Just passing on the news - I have nothing to do with the project, except for being a satisfied user :-) http://www.cnpack.org/showdetail.php?id=764&lang=en

Hi Guys. Can anybody confirm if this is the right way to send a stream in an ISAPI app? I am a little bit irritated because it seams not to be working by just calling SendStream alone ... In a standalone app everything works fine like this .... pprocedure TWebModule1.WebModule1DefaultHandlerAction(Sender: TObject;   Request: TWebRequest; Response: TWebResponse; var Handled: Boolean); var   ms: TMemoryStream;   png: TPNGImage; begin   if not Response.Sent then   begin   try     ms := TMemoryStream.Create;     png := TPNGImage.Create;     png.LoadFromFile('JESUISCHARLIE.png');     png.SaveToStream(ms);     Response.ContentType := 'image/png';     Response.SendStream(ms);     Handled := true;   finally     png.Free;    end;   end; end; ... but in the ISAPI dll I seem to have to do  it like this ... procedure TWebModule1.WebModule1DefaultHandlerAction(Sender: TObject;   Request: TWebRequest; Response: TWebResponse; var Handled: Boolean); var   ms: TMemoryStream;   png: TPNG

As a long term user of USB HID hardware, I was in need of an Android port of the Jedi JVCL HID controller software. I succeeded in writing a (simple) port. Internally used for communication with Microchip USB HID hardware. Made with XE7. Feel free to use. Simple demo included. Feedback very welcome.

No doubt many of you sell your software over the internet and place a high value on Google search results. There is a lot low-class of software that relies on your good name to piggy-back on your efforts. Let's call them parasites. I'm talking about the fake virus reports, the fake malware reports, the fake uninstall trouble reports, etc. These parasites seem to get nearly as much (if not more) Google attention than my own software does. Typically they show as high as the 2nd page of Google results. Is there anything you do to combat these sleazy parasites? Do you know of a Google reporting tool? You would be correct if you guessed they piss me off.

Any one using the DevExpress TcxLocalizer component? If so, what 's your opinion? Any good? Are there better products on the market for localising VCL applications?

I'm using Live bindings in a firemonkey app to do CRUD for some tables in our SQLIte tables.   Some of the fields are lookups to lookup tables, like State, Sex,  etc, and I have it working where the records show up in a string grid (already joined, and displaying the descriptive names from the lookup tabes). I also display the record fields in edit boxes and combo boxes when a record is selected in the string grid, and the live binding code will select the right thing in the "lookup" combo box.   I even succeeded in getting the record updated when I make a change to the edit boxes and select another item in the lookups.. However, some of the fields can be NULL in the main table , but once I select a value in the combos, I can't select NULL again (In case I want to indicate that this field doesn't matter and can be null).   Perhaps intercept the CTL-DEL key on the control and Clear the field in the dataset?   I know some of the controls like Raize and Infopower use

Blog post "RAD Studio Update Subscription" at http://blog.marcocantu.com/blog/2015-january-radstudio-update-subscription.html

hello everyone. I was playing with Delphi XE6 and found something interesting: TButton does not apply the color property. Font style, size, pitch, etc. shows ok but why the color isn't applied? TBitBtn works ok. But I don't want to use this component. i want to keep my apps clean and simple. I don't know if that is a bug or something else must be done to apply the color. if anyone knows about this issue, feel free to comment ;)

About a new feature in Spring4D 1.2 http://delphisorcery.blogspot.com/2015/01/new-dynamic-array-type-in-spring4d-12.html

Looking for some fun code snippets like: - unnecessarily convoluted code - obfuscated Delphi code - shortest line doing real wonders - totally nonsense code of the day for a session coming soon. Must be short, easy to describe in a minute. better if you email me directly (or via google+) than share here, or we'll spoiler the session.

Someone mentioned fluent programming recently. Breaking code of the day after the ORM got out of sync with the DB and many lines of manually typed code needed to be updated.   (Application.MainForm.ActiveMDIChild as TMyForm).AutoFillNewOrderTab(OrmGeneratedDataSet.FieldByName(ConstFieldNameOrmGeneratedFieldNameW).AsString,     OrmGeneratedDataSet.FieldByName(ConstFieldNameOrmGeneratedFieldNameX).AsInteger, OrmGeneratedDataSet.FieldByName(ConstFieldNameOrmGeneratedFieldNameY).AsInteger,     OrmGeneratedDataSet.FieldByName(ConstFieldNameOrmGeneratedFieldNameZ).AsFloat); A few of the error messages: [DCC Error] MainForm.pas(210): E2010 Incompatible types: 'TObject' and 'string' [DCC Error] MainForm.pas(211): E2010 Incompatible types: 'string' and 'Integer'

Note to self: When sending our xml schema to a third party, make sure to mention they do actually have to follow the xml standard and include the encoding attribute in the xml header if they intend to send files in anything but utf-8, like say windows-1252. Just got an email where the developer on the other side complained that this was NOT specified in our documentation...

Originally shared by Boian Mitov BitTime is launching online training for Delphi XE7 :-) http://www.bittime.it/update_online/

Originally shared by Thomas Mueller (dummzeuch) In the olden days, when log files were huge and hard disks were small, programs used a single character as the first character in a line to mark the severity of the log entry, similar to this: ! This is an error message + This is a warning message : This is a normal message # This is a debug message   I don't know about this (no marker character) Depending on the program the line also contained a time stamp directly after that character. This example is made up, I don't remember which characters were actually used. I am only pretty sure of the "!" being used for errors. I could not find any description of a log file that uses this kind of syntax. Is there a Standard for this? If yes, were is it described? I could make up my own system easily but if there is a standard I would like to use it. http://stackoverflow.com/q/28150777/49925

Hello all, recent XE7 purchaser and I just had a fun day putting together my first simple Android app. It is a simple two-tab view, each with a TPanel holding a few TLabels, a TListbox and a TButton. A TGestureManager lets one slide between tabs. I was a bit surprised to see the final apk was around 32MB. Is there anything I should do to trim down/strip the build, or is this just the baseline size due to overhead of FireMonkey?

Fluent style seems to be rather controversial theme among developers.  I would like to get some insights from those that consider it really bad, why they do, as well as opinions from other side.  Obviously I am using fluent style (with interfaces) under some circumstances and my primary reasons are:  - automatic reference counting that removes need for try..finally blocks - fluent itself is more readable, especially in longish constructions - no need for declaring variables and can be used inline additionally improving readability of more complex code I have included link to SO question that may provide more context for discussion. While I had duh moment and missed accepted solution myself, I am still interested in possibly better ways of achieving goals I asked in my question, even though I don't think Delphi currently offers other solutions. http://stackoverflow.com/q/28125514/4267244

So I'm in total n00b mode here. I'm trying to set up a master/detail relationship with two TClientDataSets, accessing two tables via dbExpress' TSQLQuery. I'd love to use something else (like FireDAC) but got a severe time constraint here and this is extending existing code. Anyway, anyone know of a clear guide for doing this? My Google-fu seems to lacking today. I've tried adapting this[1] EDN article, but it's not working and it's not clear to me how it will figure out the correct master/detail relationships anyway (ie how does it know what field in the detail table is referencing the master etc).

What does a "Sr Software Developer" in delphi mean to you? I ask, because I recently applied for a position that listed this as a requirement. I've been an independent developer for almost two decades now; while I've had employees, they weren't developers, but support staff, QA, Doc, etc. I consider myself very good with the language (<= XE2), I've written several products, make better money than a salary job, I'm comfortable dealing with any problem I run into and leading a team (or going on my own) to create something... ...But there's some really smart people here on the forum and developers who have been "heads-down" coders for the same time and find myself seeking their help to answer questions.  So what makes a Sr Software Developer? Is it technical prowess, wisdom of experience, people management, the ability to architect and sell something from start to finish? I'm not sure. Impostor Syndrome?

Hi, I'm a Delphi Developer.  I'm from Mexico. I liked your community. :D

Hi, I just updated DDL to allow hooking Delphi Interfaces by MethodName . As you probably know : hooking with MethodIndex is somehow difficult because you need to count all parents interfaces methods. The basic idea is simple: -Get object from Interface =>this is achieved by InterfaceToObj function. -Using RTTI to get method pointer inside that object. -Finaly , Insert the hook. NB: This method will works only with interfaces created by Delphi. For others interfaces you must use the HookByMethodIndex way! https://code.google.com/p/delphi-detours-library/ https://code.google.com/p/delphi-detours-library

Hi! Anyone experienced with HTML5 Builder/ Delphi for PHp/ RadPHP? I am doing a project with RadPHP XE2 and need some guidance

So I got this interface to a memory buffer of sorts. I'd like to provide TStream access to this buffer so it can be read from and written to using System.Classes.TStream, for interop with existing code. I'm struggling to decide the best approach to this trivial problem, and would welcome some thoughts from a "user perspective". It's highly unlikely I'll even provide more than one implementation of the interface, so my two primary options are: - Provide a property Stream: TStream in the interface, and have the buffer implementation return some private implementation of TStream, not unlike how GetEnumerator is done for the generic collections. Lifetime would be that of the buffer instance, so the user has to ensure the buffer is alive for the duration of any TStream operations. - A separate "glue class", a TStream descendant where I pass the buffer in the constructor. This places the burden of lifetime management of the glue instance on the user. In ei

It was a comprehensive [long] post and there have been no comments made to date; so, if I limit my request to the below someone may be able to advise me on how to inspect the delta's content or recommend another course of action. This issues only seems to occur when using MSSQL. Thank you in advance. I’d love to understand how to inspect the payload in the TFDJSONDeltas [see image] at the client or the server. I can see the name of my key field [ccustno] but I do not understand the rest of the information in the watch tree.

My git tip of the day: Every git repository should contain a .gitattribute file to enforce proper eol handling. Especially when working with multiple people/accepting pull requests. If you don't do that different people or one person working from different machines with different git eol settings, editors or operating systems will mess up things.

Any users of FireDAC TFDScript out there? Scripts produced by ApexSQL Diff, which runs fine in SQL Server Management Studio, fail when run from a TFDScript.  I am trying to figure out if it is options related, or if it is an implementation problem. Problem 1: Transaction handing causes an error:   Exception class EMSSQLNativeException with message '[FireDAC][Phys][ODBC][Microsoft][SQL Server Native Client 11.0][SQL Server]A transaction that was started in a MARS batch is still active at the end of the batch. The transaction is rolled back.'.  Problem 2: If I remove the begin tran at line 38/39 and reduce the script to only contain the create table part - it still fails silently. The spool output shows no errors, nor does any errors show in the FireDAC Monitor.  And yet - no table is created. I also suspect that multiline /* block comments */ confuse the script analyzer. Suggestions, anyone, particularly for Problem 2? #firedac   #script   http://pastebin.com/dzR8T6fC

However, they are being placed in the wrong spot, and the layout only works when Store = true. It's a good question and I'd like to know the answer too.

How can I retrieve (if possible) this information via Firedac component (i.e. without calling directly gstat, capturing output and parsing it) ? TIA

"inherited" keyword added to each time I drop a new visual component on the descendant and click to add an event. Delphi XE2, I've got a TFrame that's descended from a couple other TFrames. One of the parent TFrames has a few visual controls... When I add new UI elements to the descendant form and click over to the object-inspector to add an event-handler. Each event that I add, will always get a template created with the keyword "inherited" added. I understand the need for this, when dealing with visual-components from the parent form. But I'm confused with new UI elements. Is there a reason for this? http://www.youtube.com/watch?v=y0UiX6kLvvs

I am using FireDac Monitor which stops after a short while with a message "EOF found". Has anyone encountered that before and maybe solved that problem?

Loopless code of the day ;) function GetCommonDir(const paths: TArray ): string; var   files: IEnumerable ;   matchingChars: IEnumerable ; begin   files := TEnumerable.Query (paths);   matchingChars :=     TEnumerable.Select (TEnumerable.Range(0, files.Min(       function(s: string): Integer       begin         Result := Length(s);       end)).Reversed,       function(len: Integer): string       begin         Result := Copy(files.First, 1, len);       end).Where(       function(const possibleMatch: string): Boolean       begin         Result := files.All(           function(const f: string): Boolean           begin             Result := StartsText(possibleMatch, f);           end);       end);   Result := TPath.GetDirectoryName(matchingChars.First); end; Ok, I admit, in C# it looks not so weird and much nicer ;p var MatchingChars =             from len in Enumerable.Range(0, Files.Min(s => s.Length)).Reverse()             let possibleMatch = Files.First().Substring(0, len)          

I'm looking for a Delphi (XE5+) developer in Switzerland. The company is situated near Bern, has around 20 employees and does business in the sport-eventmanagement domain. Your main tasks are the development and maintenance of an ERP and a CRM (inhouse developed tools). It's a requirement to work locally due to the business processes, that have to be understood (no remote work). Basic German language skills are also required. Let me know if you're interested or if you know potential candidates. Thanks a lot!

Is there any Tool/Plugin/Expert for Delphi which offers an Enhanced Scroll Bar like Visual Studio? http://blogs.msdn.com/b/zainnab/archive/2013/07/02/visual-studio-2013-preview-enhanced-scroll-bar.aspx http://blogs.msdn.com/b/zainnab/archive/2013/07/02/visual-studio-2013-preview-enhanced-scroll-bar.aspx

FYI - Added a Delphi Job Resources category to the directory. I also added the various recently mentioned Delphi job resources as separate posts under that category.  If you know other resources than those already mentioned - feel free to add them! #freelance

Do anyone know if someone supports the jedivcs? We use it for many years now and would like to use it for XE7 now.

FireDAC WTF of the day ;) Conn := TFDConnection.Create(nil); Conn.DriverName := FireDriverLink.BaseDriverId; // The above lines were actually in a function in the worker pool for tgt in targetlist do begin   Conn.Params.Clear;   Conn.Params.Values['Server'] := tgt.Host;   Conn.Params.Values['Database'] := tgt.DatabaseName;   Conn.Params.Values['OSAuthent'] := 'No';   Conn.Params.Values['User_Name'] := tgt.UserName;   Conn.Params.Values['Password'] := tgt.Password;   Conn.Connect;   Exception: Driver name not set. I added the above clear since I would be reusing the connection for multiple databases in a loop, and it took me a few rounds in the debugger before I figured out that the property mapped into the params list instead of a property field of it's own. Lesson learned.

Thanks to Eli M for pointing out oDesk as a place to find Delphi freelance work. Not only can you find jobs there - if you need temporary manpower, you can post jobs there as well. #freelance   https://www.odesk.com/o/jobs/browse/?q=Delphi

With TClientDataSet you can load from a file at design time, can you do this with TfdMemTable? It's a really useful feature.

FD REST MSSQL update not posting  I built a test app using “Using a REST DataSnap Server with an Application and FireDAC” found on http://docwiki.embarcadero.com/RADStudio/XE7 as a starting point. The sample uses InterBase and everything worked as expected. I then added a FD connection to a MSSQL server and a couple of FDQuerys and created the respective GET’s and ApplyUpdate functions and procedures. The GET’s work and my controls are properly populated however when I execute the Applyupdate code the MSSQL GetDeltas and ApplyChanges seem to function the same as the respective InterBase ones do [producing no errors] BUT the updates are NOT applied. I’ve run the debugger on the server and the client but am unable to locate the flaw. The server is a desktop app so I added a grid to see if there was something I could discover. I found out that I had to set the FDQuery CheckReadOnly to false to get my updates to apply. I thought that would do the trick but not so. I’d love to understand h

18 years+ Delphi experience since it's frist version, looking for remote work.

Howdy all. Is it possible to get the IDE to build .res files from a RC file, without resorting to a pre-build event? There is this syntax:   {$RESOURCE filename.res filename.rc} But that is only to show filename.rc in the project manager (which doesn't seem to work for me but I don't really care :-) ) -  http://docwiki.embarcadero.com/RADStudio/XE7/en/Resource_file_(Delphi) Currently I am using a pre-build event to do the compiling for me: brcc32 ..\relative\path\to\filename.rc

There is an unwanted system beep on Mac when handling arrow keys. How do I eliminate the noise? //FMX TViewport3D can respond to keyboard: Viewport3D.CanFocus := True; Viewport3D.SetFocus; Viewport3D.OnKeyUp := HandleKeyUp; The arrow keys work on both Windows and Mac, but Mac keeps playing the sound.

does anyone have success build recoding app using free audio library for android & iOS ? what name of that library? i have build using BASS , but  unfortunately it's not free again now.

I am searching for a barcode component or library with which I can generate pngs of barcodes in a Delphi webbrokler  backend. Any suggestions? I think neither CGDev components nor winsoft FMX or VCL components will help me, because they would not work from a webbroker app.

OK, I know it's stupid and I really shouldn't care, but Delphi is now less than 50 points behind C# at http://www.code2014.com/ . Wouldn't it be nice for the Delphi guys to beat Microsoft just once? Even if it is, as I'm sure many of you will point out, in a completely stupid, meaningless competition. Get tweeting "Delphi #code2014 " or you don't love Delphi :) ... only 12 hours left ... http://www.code2014.com

OPs "multilevel" comments (i.e. the fact (* *) takes precedence over the other block-comment { and } is a boon. When debugging a larger block i can comment out small ones and then comment out the whole block containing these smaller block comments. I remember showing this to people using other languages and they got pretty impressed. But this was a loooong time ago. Anyone has a hang on if this still is something to brag about for OP?

Yesterday, for the first time, I tried to create a multi-device app on XE7. Selected the app type in the wizard, clicked the button, and the IDE crashed. Made three tries, same result each time. I have update 1 in place, is there something else needed to make this work? UPDATE: I have e-mailed Andy Hausladen with info from the Windows Event viewer. Uninstalling the fixpack, however, did not solve the problem.

"with" almost killed me this morning. I copied 5 lines from a library demo and did not un-with it. I was going very deep into other stuff before i saw it. Someone wrote a source analysing tool recently. /Perhaps/ it's possible for a tool such as FixInsight to warn when variables have the same name inside a with as outside... (edited only spelling)

Just a WTF: TMyRecord = record   AString: string;   AnInt: integer; end; TMyRecordHelper = record helper for TMyRecord   function DoCalc: string; end; Why.... just.. why....

Does anyone know how to contact ADUG tech support? I've tried emailing the addresses on the ADUG Organisers page, and sent a G+ message to one person I found too. But no luck. Reason is their blog has been down for a month, and I want to read articles like this:  http://members.adug.org.au/2011/12/15/how-to-create-your-own-firemonkeyimage-filtereffect-to-use-with-firemonkey/ (It's the whole members.adug.org.au domain. I'm sure it's on the Wayback Machine, but that's not the point. Better to let them know their website has a problem.)

How can I get the list of all updates / patches / hotfixes that have been released since, say XE7 Update1? The EDN registered download area is a bit random it seems.

With FMX, is it possible to create a TButton with a shortcut key, for example "Run" with the "R" underlined, so that I can press alt+r (on Windows) to invoke the button without clicking on it? I tried setting the "Text" property of an FMX' TButton to "&Run" but that doesn't seem to work.

Can someone please explain this, or is it a bug in the debugger?

Since TDataModule creation and destruction synchronizes via a shared global lock, what else isn't thread safe when it comes to data modules? I need to do some entirely independent SQL work (DBX) in a background thread. Delphi XE6.

I know that I risk to be blocked by some of you for spamming this community with my calls to tweet #code2014 delphi. its Nick Hodges​ fault who got me started :-) we passed c++ and if about two hundred more people from this community would engage we would pass c#. why not?
