I'm trying to migrate my components from D2010 to DXE3. I organized my components folder like this:     Source folder     Packages folder     D14 folder (dcu's for D2010)     D17 folder (dcu's for DXE3 32bit)      What folder would be a good place to put dcu's for DXE3 64 bit?

Hello! Let's see if I can start a flame... heeheh :) http://www.utf8everywhere.org/ Wanna give it a go? :) A http://www.utf8everywhere.org/

I'm starting to believe that my predecessor doesn't exactly know what he was doing...  function ReadFromDatabase(P_1, P_2: integer) : boolean; var   Query: TQuery; begin   Result := false;   Query := getQuery();      if ( Query = nil ) then     exit;   try     Query.ParamByName('P_01').AsCurrency := P_1;     Query.ParamByName('P_02').AsCurrency := P_2;     Query.Open();     Query.First();     Result := true;   finally    if ( Query <> nil ) then     begin       Query.Close();       Query.Free();     end;   end; end;

Is there a way to enable antialiasing in FMX under GDI+ besides downscaling of prerendered bitmap?

A bit of bitterness (Off topic) This community seems to have several experienced developers from all around the world, and I would like to have opinions about this. I'm an experienced developer, more than 15 years of professional activity mainly in programming (not counting the early ages with Amstrad, Atari, Amiga ...). I've seen several environments and languages : Linux, Windows ;  VB6, VB.NET , C#, Python, and now Delphi.   Would I advice anyone, with a passion in programming, to do my job ?  the answer is of course : NO Why ? Because if you love programming, your skills will  never been paid what they worth. You want to earn money ? Become consultant, commercial, anything but : don't put your fingers in the code. My impressions are : most of the companies hire young developers , hoping them to make shiny programs made like sh*t  to give to their customers. No matter it's crappy inside : you must sell, quicklu, and after all, what's the duration of a software in

Anyone know the substitute for FindBinding in XE3 "(Item.FindBinding('select') as TButton).Tag:= 1" The code above only works in XE2 Thanks

OK, I would like to learn the relationship among DSharp, Spring4D, and any other projects which may be related. And especially, is the future plan for them to work together, or does Spring4D become the ultimate single framework? Given limited time for study, inquiring minds would like to know...

Hi, I'm just curios if there any TWebBrowser-like control for FireMonkey2?

Q. I am using Tibquery and want to store its result to a clientdataset without using dataset provider  Any thoughts on this..?

Has anyone come across the issue of calling WinApi.MMSystem.PlaySound returning false with an error code of 0?  It works fine in the context of a simple application, but fails in a much larger application.

Does anyone know how to make tfrxMemoview height increase automatically  (stretch) base on it's content. i put a tfrxMemoview  inside a databand, i set the stretch property of databand to true and tfrxMemoview  stretch mode to  smMaxHeight but it doesn't give me the expected result.... thanks

How do you prefer to store application settings? Which component/library do you prefer for this task? Using TRegistry seems to be not optimal for me

Anybody have any opinions about a good book on Firemonkey?

MailMerge adventures, continued... OK, I have concluded that any path but using the components statically installed on a form or frame is more pain than it is worth. So as to my previous post, never mind!

OT: Can anyone do me a favour and check, whether my domain ddobjects.de is available? I moved to a new hoster last weekend and although everything seems to be fine, there are no downloads or anything else. Looks as if it still resolves to the old host?! Thank you!

is anyone here using tms grid ? i need to get the previous (old) value of a cell  on event on validate cell. how can i get it. because i need to make comparison between the old value and the new value.  Here is the on validatecell event procedure  procedure TfrmKasirUmum.grdMenuCellValidate(Sender: TObject; ACol, ARow: Integer;   var Value: string; var Valid: Boolean); begin //  end; if i give the valid parameter to false, the new cell value will be revert back to the old value. i certainly believe there is a way to get the old value. but i don't know how. so please help me.... thanks in advance

This tutorial shows how you can have a Microsoft Office (Word, Excel,…) call your Delphi application. For the demonstration, I will use Word. From Word, a macro will call my Delphi application which will prompt the user for some data which will be inserted in the Word document. http://francois-piette.blogspot.be/2013/01/microsoft-word-or-excel-calls-delphi.html http://francois-piette.blogspot.be/2013/01/microsoft-word-or-excel-calls-delphi.html

can anybody help me with TVirtualStringTree? I've never used this component before and few days ago I installed it. I need to create additional columns with checkboxes. As I understand there is the only way to do it - draw them manually in AfterCellPaint event handler (without node editing state).  So I've painted checkboxes and now I need to handle clicks on them. In Click or ColumnСlick events I can find out what cell was clicked, but how do I know that user clicked inside checkbox? I need cell rect coordinates.. how to get them? Or there is another way? this sample source : http://pastebin.com/bipekFmC http://s13.postimage.org/uvolcwjjr/123.png

I see that 'Delphi iOS beta for XE3' is available for registered users . However, I couldn't finish the sign-up procedure. Did somebody else manage to sign up for the beta or is it just my account that won't work? I do have a registered copy of XE3. https://members.embarcadero.com/FieldTests.aspx

Yesterday there was the 1st official DORM training in Milan. During the last month, I've been working a lot on usability side! http://code.google.com/p/delphi-orm/ http://code.google.com/p/delphi-orm/

I need to sort ANY TDataset descendant - my first idea is to: First look for IndexFieldNames property using RTTI - if found use it to sort TDataset. If property IndexFieldNames doesn't exists Create temporary TClientDataset - copy data from my TDataset and sort it using TClientDataset.indexFieldName. Sorted data copy back to TDataset. Maybe you have better ideas?

Anyone noticed multi-threading performance issues with SysUtils.Now? Or the TimeStampToDateTime WinAPI call in TryEncodeTime? I've experienced weird contention and performance issues with it that went away when switching to GetSystemTimeAsFileTime.

What design application can I use to generate Data to TPath component in Firemonkey?

OK, I need to do some Word automation, and in particular, to build in my app a database that will be passed into Word for MailMerge. This is not something I have ever approached before. If anyone has some hot tips on components, and/or whether and to what extent MailMerge automation is possible, I would appreciate it.

HEEEELP! Using TComPort to communicate with hardware device, we're experiencing a lot of incomplete packet responses, especially under Windows 7, Windows XP is better, but we're doing it under W7. When using 1024bytes for input and output buffer, we're losing about 20% of the packet data(the end of it), when using a 24bytes input and output buffer, it seems to loose less and less frequently. The packets are around 14bytes max and we're clearing both the input and output buffer after each request and response. Anyone got any idea? UPDATE : using Delphi 2010

Although it is not a very good test, it has some interesting results... http://andremussche.blogspot.nl/2013/01/datasnap-ro-rtc-mormot-wcf-node-speed.html http://andremussche.blogspot.nl/2013/01/datasnap-ro-rtc-mormot-wcf-node-speed.html

Okay, you C types:  This seems pretty straight forward to translate: short GeoEngCheckDbAvailability(char *pSearchPath, char *pDbName, char *pUserDictionaryPath, short *pDbFlags); But the translation I have is: function GeoEngCheckDbAvailability(pSearchPath: PAnsiChar; pDbName: PAnsiChar; pUserDictPath: PAnsiChar; pDbFlags: pshort): short; seems to be causing problems, specifically AV's. Help?

I came across this interesting paper: Patterns of Parallel Programming. Although it deals with .NET, most if not all concepts should be applicable to Delphi. http://www.microsoft.com/en-us/download/details.aspx?id=19222

Is where a way while debugging to step into a procedure  in such a way that you get immediately into the procedure body without getting into the procedures involved in computation of the procedure arguments? It's neighther F7, nor F8, it's something inbetween.

Hello! A new video demonstrates a recent feature - profiling single methods - of the upcoming DDDebug release. http://ddobjects.de/dddebug/video-profiling-methods

Hello! I am sure I am overlooking something stupid :) This is my code: private     FUserToken: String;     FUserService : IUserService;     { Private declarations }   public     { Public declarations }     procedure DoLogin( UserName, Password: String );     procedure DoGetEmployeeDetails( Token : String; out EmpDetails : TEmployeeDetails );     property UserToken : String read FUserToken; ... procedure TDMMain.DoGetEmployeeDetails(Token: String;   out EmpDetails: TEmployeeDetails); begin   if Not Assigned( FUserService ) then     raise Exception.Create('login first');   FUserService.GetEmployeeDetails( Token, EmpDetails ); end; procedure TDMMain.DoLogin(UserName, Password: String); begin   FUserService := GetIUserService;   FUserToken := FUserService.Login( UserName, Password ); end; The Login call works, but apparently when I try calling GetEmployeeDetails, it doesn't even get into the webservice server(put a break point and does not stop). Ideas? Thanks! A

OK folks... how would you solve this.... I have a Delphi desktop app - it requires a user to be logged in to use it.  We now have a requirement that the app needs to lock the user out after an inactive period, at which point the user can't do anything without reentering credentials. Here's the rub.  We need the main thread to continue doing stuff while the app is locked.  So I obviously can't show a modal dialog - that stops the main thread.   Our first crack was to use DisableTaskWindows - that worked well, until the main thread pops up a modal dialog over the currently active form (the user lock screen).  At that point the app basically locks up. So, to recap,  user session times out, a lock screen shows, we call DisableTaskWindows, which locks other background forms, but keeps the main thread running, the main thread pops up a modal dialog on top and we're locked up.   Help! //cc Nick Hodges Martin Binder 

I don't even have to post the implementation -- the interface declaration should be enough to give you the gist of things: function  LoadGlobalMemoryTables (LookupUtility : boolean; var sErrors : AnsiString): boolean; I mean, just the name should send shivers down your spine.  ;-)

A more general approach to my TComboBox problem, an example: Let's say we have an order entry screen where you create orders for existing customers. So you want to choose a customer from a list of 10.000+ customers (in a table). What controls would you use so that the user can select the right customer with as few keypresses as possible? We are trying to re-write an MS Access application in FMX. In Access a combobox with 10.000 rows was no problem. Just type the first letters of the name and you skip to the right row. But I cannot find a good replacement for this in FireMonkey.

New Post, performance DataSnap, I'm thinking of using marmot, DataSnap still poor, what do you think? follow link http://robertocschneiders.wordpress.com/2013/01/09/datasnap-analysis-based-on-speed-stability-tests-part-2/ http://robertocschneiders.wordpress.com/2013/01/09/datasnap-analysis-based-on-speed-stability-tests-part-2/

Is it just me having two coding styles, one for work projects and another for the personal ones?

Anybody know good library for D7 to boost my poor TCanvas skills? (gradient, alphablending, etc.)

FMX and LiveBindings combobox I am looking for a combobox that, when you start typing in it, selects the matching items. Just like a normal combobox in Windows. However, there seems to be no way you can type in a FMX TComboBox. What do you guys use for this? All suggestions are welcome!

Cool test with Firemonkey 2 after details, now is 3:24 a.m.

Pascal for the first time surpassed the Delphi/Object Pascal in the TIOBE Community Index for January 2013. "Other interesting moves of 2012 are the renaissance of C++ (+1.09%, boosted by Microsoft) and Python (+0.96%). On the other hand, C# (-2.57%, due to its late entrance in the mobile market) and Delphi (-0.65%) lost considerable market share." http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html

Hello! I have uploaded a new video demonstrating the IDE integration of the next release of DDDebug. DDDebug is a collection of debugging tools for Delphi which contains several modules: a memory profiler, a thread viewer, a module viewer and an enhanced exception handler. http://ddobjects.de/dddebug/video-ide-integration

What would be your main requirements for ORM/OPF framework in case you want to use one?

Ugly code of the day : class function TFile.DoReadAllBytes(const Path: string): TBytes; var   LFileStream: TFileStream; begin   LFileStream := nil;   try     LFileStream := OpenRead(Path);     SetLength(Result, LFileStream.Size);     LFileStream.ReadBuffer(Pointer(Result)^, Length(Result));   finally     LFileStream.Free;   end; end;

Class properties and class var's - How do you use them? There are times I am wondering if they really are just a reinvention of global variables.

case statements for enumerated types with huge chunks of code for each one scream out "Make me into separate classes".

Code of the Day: WaitForSingleObject(hLockHandle, INFINITE);

Yes, I'm going to bring this up because the codebase I'm working on PROVES MY FRIGGIN' POINT!  (Sorry for yelling....) Okay -- the programmer who wrote this stuff uses FreeAndNil all over.   And as a result, I have to thoroughly investigate each one to figure out why .  Is it because they were just duped by the FreeAndNillers?  Or is there actually a reason for the pointer to be set to nil?   Sometimes there is a reason, and sometimes there isn't.  But I have to check every single time. Great. Fire away, I don't care.  ;-)

how to make sending data from the client to the web service delphi if the tables on one database has many fields and 50 are effective and do not overload the network.

Looks like LogMeIn can greatly effect the framerate in FireMonkey.  You can disable LogMeIn's mirror display driver, by going into the Device Manager, Display Adapters, LogMeIn Miror Driver, and disabling.  Gone from about 5fps to fluid.

Hello! A new release of my Delphi Component Installer is available for download. This release is the first Beta, installation within Delphi 5 to XE3 should be fully supported.

Comment of the Day: // hardcoded 's computer IP - hopefully SMTP server is running there...

That sinking, disappointing feeling when you remember that you can't use anonymous methods in Delphi 7.

Auugh!  Seriously, everything doesn't have to be a thread!

Sorry if it will look like a rant but it got me thinking today. Who at Emba thought it is good idea to inherit IEnumerable from IEnumerable and IEnumerator from IEnumerator??? And why all containers from Generics.Collections, Classes, etc are not implementing those interfaces?

I need an advice : In a project with severaI applications, I have 2 applications (let's call them AppA and AppB) , accessing to a  database through a DataSnap server. At the moment, these applications are one the same PC. AppA and AppB are communicating through Windows Messages. Now, I would like to be able to move AppB on a remote computer. I could create a socket communication between AppA and AppB, but coudn't  I use the DataSnap Server as a component for a "traditional" socket communication ?

cxGrid (devexpress) works fine with ADOTable, but I think it doesn't work with ADOQuery am I right, or I've just missed something??

Want to ask something, is it same to do this: cdsMaster.Data := cdsSource.Data, so far i know that doing that i will copy all the data of that clientdataset dan will cancel the transaction if it is currently in edit or insert mode. So is there anything else i should acknowledge? thanks

No, sorry, I was wrong.  *This* is the Code of the Day: try   ... except   On E:Exception do   begin     raise Exception.Create(E.Message);   end; end;

Dependency Injection: useful when you have an ever changing set of objects, plug-ins, etc; a burden when  you have a strict, well defined set of objects that isn't going to change any time soon. Thoughts?

Code of the Day: raise Exception.Create('User hit cancel.  That''s mean!');

Hello! I have released the code of the before mentioned Delphi Component Installer. The download also contains a sample but no documentation (hopyfully I'll be able to add it within the next few days) yet. If anyone could review the code I'll really appreciate :) Regards, Stefan http://ddobjects.de/free-software

I know this has been well covered by others, but I needed this for my book, so here it is: http://www.nickhodges.com/post/Enumerating-and-the-for%E2%80%A6in-Loop.aspx http://www.nickhodges.com/post/Enumerating-and-the-for%E2%80%A6in-Loop.aspx

A pretty good read on how to go from theory to code! Originally shared by Robert Anderson Algorithms define you, your behavior and the probability that you will read, plus one, comment on, and share this post. . . . Outcome = prolly not http://codecapsule.com/2012/01/18/how-to-implement-a-paper/

Updated the code in my last blog article. http://francois-piette.blogspot.be/2013/01/make-sure-form-is-visible-on-existing.html http://francois-piette.blogspot.be/2013/01/make-sure-form-is-visible-on-existing.html

is there a function in SQL where you can get current time and date, and use it somehow : select * from table where currentDate - anotherDate = result

I am working on an installer for Delphi components - no full fledged setup as Inno Setup or others, but just a small, simple one which automatically registers your packages within Delphi (5 to XE3), adds search- and library pathes etc. The installer will be open source, the first Beta available for download at this weekend. If there's anyone who would do a code review and testing, I really would appreciate :) Thanks in advance.

How do I stop the bloody Instant Upload from trying to share my photos automatically???? Anybody knows??? Thx

Does anyone know or use this library? http://synapse.ararat.cz "The SYNAPSE library aims to create a complete library of classes and functions that would markedly simplify application programming of network communication using Winsock. At first glance this effort might seem needless as there are many free components covering this area, However they mostly use asynchronous methods while SYNAPSE library operates in a synchronous method. After having a look at 'competitive' libraries I must say all of them were created relatively early (for Delphi 1.0 and Win16). Thanks to cooperative multitasking, a synchronous access to Winsock was not possible. This is the reason why Microsoft added asynchronous mode to Winsock implementation." http://synapse.ararat.cz/doku.php

I have just saw a comment of Alexey Petushkov who pointed out the open source project:  http://owlyci.com/  package manager for Delphi  So it is a similar solution like nuget? (A competitor of RADStore?) http://owlyci.com/
