Hello everyone, I'm Italian and I'm sorry for my bad english.. Can I ask advice on how programming? I stayed to Delphi 7, I recently restored to programming for to make a management program design of pressure equipment, but I was always applications with MDI child form.. 1- I would like to evolve my way to program and use applications with the ribbon .. I familiarity ( Delphi EX2 ) but still we did not.. How can I make a file with the ribbon but using + form ?! ( MDI FORM ??) 2- What you need to do to make a program that is streamlined format from multiple files? (one for each form?) , currently Barring the configuration files of preferences ( XML or old ini ) and the DB , my programs are made up of a single exe file very large! if you give me some advice I'd be grateful .. thanks

Is it possible to prevent the DFM file from being updated? See this SO question from Brian Long http://stackoverflow.com/questions/5486957/is-there-a-delphi-option-to-lock-the-design-layout-of-a-form-against-acciden

Quite offtopic, but who knows much about the internals of how Delphi's debugger is implemented? I was reading these two articles on "hard" vs "soft" debuggers, and I suspect Delphi's is a hybrid. http://blogs.msdn.com/b/matt_pietrek/archive/2005/02/14/372424.aspx (hard vs soft debuggers in Windows 3 (!)) http://blogs.msdn.com/b/jmstall/archive/2004/10/13/241828.aspx (implications of the soft / inprocess debugger in .Net) I used to think Delphi's debugger was a "hard" one (in modern terms, different to the definitions in the first article), but some time ago, could be years, I noticed there seem to be extra threads in a debugged process which I speculate are used by Delphi for some parts of its debugging - maybe evaluation, etc. I'm sure they never used to be there. So at some point, if this is right and I'm not imagining it, the debugger changed how it worked and/or became a hybrid of the two models. It's sparked my curiosity. Doe

Did you know it is possible to use ORM over NoSQL engines? This blog post describes how mORMot is able to translate a regular SQL "where" clause to a well-formatted MongoDB query object, so that you could share the same business code with RDBMS (FireBird/Oracle/MSSQL/SQLite3/PostgreSQL...) or MongoDB, at runtime. http://blog.synopse.info/post/2014/11/28/ODM-magic%3A-complex-queries-over-NoSQL-/-MongoDB

Need help describing a user preference option to play all videos in succession. I've created a program that contains eight chapters (they are actually videos) and I have a user preference that when checked will play all eight chapters in succession one right after the other. For Example: When Chapter 1 finishes Chapter 2 starts When Chapter 2 finished Chapter 3 starts so on and so forth... When Chapter 8 finishes it starts over again with Chapter 1 I can't seem to come up with user friendly phrase to describe this option. Here are some of the phrases I came up with so far... Loop Presentation Play Continuously Play Chapters in Succession All of these seem to miss the mark as far as conveying the meaning in a succinct but user friendly way. What do you think would be a good phrase to use for this user preference option?

Parallel Code Library - Terrible Real-World Performance I have some time consuming code which I thought would be an ideal candidate for the parallel code library. The code simplifies the boundaries of zip codes i.e. takes out all the small zip-zags. This involves a lot of perpendicular-distance-to-line type of calculations. There is a little memory allocation since for each zip code I need to create a list of possible intersecting lines.  A non parallel version completed the transformation in 4 minutes 56 secs on my i7 desktop (4 core plus hyper-threading).  The parallel implementation was simple. I used the Parallel.For loop with a stride of about 1000. To my surprise this completed in 5 minutes 12 seconds.  Yes the parallel version is slower than the simple for loop!! When I look at the task manager the CPU utilization of the parallel version is about 20% while the routine is running.  I then switched to ScaleMM2 as the memory manager. This version takes only 1 minute 34 seconds and

Marco Cantù's opening keynote from CodeRage 9 is up.  I'm listening to it in the background while doing other work. Some things that were interesting to me:  - Gives an overview of the state of Delphi and where Embarcadero see the product to be placed (useful to me, since I want to reply to this thread soon:  http://arstechnica.com/civis/viewtopic.php?f=20&t=1261959 Please don't everyone swarm it at once, a rush of posts by new posters will seem like I'm spamming.)  - More source control than just Git and SVN is coming (here's hoping for Mercurial!)  - Focusing on 'developer productivity in the IDE' noting that Delphi used to be great but has fallen behind 'some other products'. This is especially interesting to me, as someone busy writing plugins to make the IDE better ;) I don't know of course what this means - whether it means fixing Error Insight, or whether it means entirely new tools. If the latter, hopefully we won't duplicate eff

Is EMBT's Boolean dockwiki wrong? http://docwiki.embarcadero.com/Libraries/XE7/en/System.Boolean Is states: A Boolean value is considered True when its ordinality is 1 and False when it's ordinality is 0 (zero). Wouldn't a more accurate statement be... A Boolean value is considered False when it's ordinality is 0 (zero) and True when it's ordinality is not 0 (zero). When I do a BoolToStr I see -1 (negative 1) when True not 1 but I always see 0 (zero) when false. Wat am I not understanding? http://docwiki.embarcadero.com/Libraries/XE7/en/System.Boolean

Hello all, is someone who using ODAC.9.3? i have one question about blob field.

Sorry I asked this earlier in Discussion forum. But asking here again hoping to get some answer. I am trying to validate a user against table aspnet_Membership that is created by asp.net MVC 5 entity framework . As most of you know it has hash password with PasswordSalt. Any idea how to validate user against this table aspnet_Membership  from Delphi? FYI table aspnet_Membership  has following fields   username, userid, password, PasswordSalt, binHash1 Thanks.

hey there, everyone. I learned to use delphi 7 end of 2006 and since, never used again. But now, by destiny, I have the chance to back, even with a lack of memory about. My point is: Is there much diference between delphi 7 and Embarcadero's newest versions? sorry for my english and thanks since now.

Has anybody an idea why Apples tight integration between OS, exclusive inhouse dev environment XCode and App Store is not under investigation by competition lawyers/politics? As I have read today the EU might try to prohibit search engine suppliers to combine their business with the offering of other products in a move against google. Isn't Apples close shop attitute on its plattform also a problem for competititon? Well I guess they try to proove it is not at the moment, since XCode is rated with two stars in the App Store and reported to be barely usable in the new version.

CreateRotationMatrix3D Is it a good time now to do a quick retest in XE7?

A while back i asked if anyone had a trick for using the IDE in a VM. The specific problem is that i resize the VMs window frequently and the IDE does not (by design) synchronize the size of the windows when it goes into the debug layout. Anyone of the people into extending the IDE that agrees with me that this can be very annoying? An option to have design and debug layout's synchronize their size and position would be cool.

Speed of Generic TList In one of my apps I have a core data structure which uses a Typecast TList to store a list of TMyObjects. There are about 6 million of these TMyObjects scattered among about 33k lists. Speed and memory usage are important. I need to be able to enumerate and access the lists quickly. Memory usage is also important as I have, on occasions, hit the 2 Gb memory ceiling of Win 32!! My question is, would there be an advantage or disadvantage in converting the Typecast TList to a generic TList ? My criteria would be speed of enumerating / accessing and size of memory footprint - Thanks!

Can you vote for this Quality report, please? It's a serious issue where math done with TVector3D gives the wrong results - completely wrong. The reason is that it is not a 3D vector, despite its name, but a 4D vector. Any normal math you do, such as adding a scaled vector to a 3D point, gives the wrong result. Eg, for the expression "Pt3D + Vec3D * Scalar" where Pt3D is TPoint3D.Create(0,0,0), Vec3D is TVector3D.Create(1,0,0) and Scalar is Single = 12, you would expect a resulting 3D point value of (12,0,0), right? No. You get (1,0,0). Which is wrong. Even worse, TPoint3D is the stand-in for a real 3D vector. System.Math.Vectors goes so far as to deprecate vector operations like a cross product on the vector type, and puts them on the point type instead - something that makes no sense. Reading this code with some knowledge of 3D math makes my head hurt. Using it is even worse (I just fixed several bugs by replacing my usage of TVector3D with TPoint3D, despite wanting a

How optimize new RTTI (in XE4) ??? it's very slow !  when I use the old rtti method (in TypInfo, Set/GetxxxProp family...) it's 5/6 times faster !  mostly is the TValue. Why ? I writed a function in a class to scan all published properties (with rtti) and compute CRC 32bits on it ; my version with old rtti is 8 times faster than the new rtti !  unbelievable !!! Unfortunately , for this example, I don't have the new rrti version (because too slow). but the old rtti (and the faster) is: function ComputeValueCRC(AOldCRC:Cardinal; const AObj:TObject; AProp:PPropInfo):Cardinal;inline; var   s:string;   ws:WideString;   i:Integer;   i64:int64;   f:Extended; begin   case AProp^.PropType^^.Kind of     tkInteger, tkChar, tkEnumeration, tkWChar, tkSet:     begin       i := GetOrdProp(AObj, AProp);       Result := ShaCrcCompute(AOldCRC,@i, Sizeof(i));     end;     tkString, tkLString, tkUString:     begin       s := GetStrProp(AObj, AProp);       Result := ShaCrcCompute(AOldCRC, Point

Stupid 3rd party component (developers) of the day: After installing some commercial component I have 2 Lib directories for 32 and 64 bit which both contain all binaries (like dcu, bpl and dcp) AND all sources (pas, dfm and dpk for all Delphi versions). Seriously guys...

Migrating to FireDAC: The devil is in the details I recently discovered that some of the few queries that we have that return a large rowset,  would max out at 50 rows. It turns out that TFDQuery.FetchOptions.Mode defaults to fmOnDemand, which means that the query first returns a default of 50 rows, and then fetches 50 more as you MoveNext past the 50 first.  Other options are fmAll, fmExactRecsMax, fmManual. Since we still are in the "make it work" and not in the "make it fast" stage, I switched to using fmAll. Interestingly, RowCount by default also returns 50 even if the query actually matches more rows. and there is a TFDQuery.FetchOptions.RecordCountMode setting that can be modified, as well: cmFetched, cmVisible, cmAll. This differs from ADO TQuery, which will retrieve all rows and the full record count by default. TFDDataSet has the same settings, and there are numerous other tweakable parameters that I need to explore for both of these components.. #FireDAC

Need Suggestion: Local DB and Driver for XE2 VCL app I'm looking to dump the storage-mechanism that I've been using (flat, text files) in favor of a database. Basically, I'm moving into a different customer market that needs more reporting and my current method of loading/saving flat text-files into/from a TObjectList is just not cutting it. It's been a while since I looked into this and most of my googling turns up results that just look stale. In previous apps, I used ZeosLIB and MySQL. It seems like that's still an option, by replacing MySQL with FireBird, but I'd like to get opinions. My requirements are: 1) Still actively supported and developed 2) Works with Delphi PRO XE2 VCL 32-Bit 3) Supports latest XE(X) with 32/64-Bit VCL/FMX (later migration) 4) Uses local DB files for storage with no external service needed (everything should run in the EXE or linked DLLs aka "embedded") 5) License is free allows for royalty free redistribution in software

FastMM4 & Parallel Programming? I have seem a couple of comments which imply FastMM4, Delphi's memory manager, doesn't perform well in a parallel applications. Having Googled around a little I came across ScaleMM (see link). It claims better performance in multi-core apps.  Does anyone use ScaleMM in production applications? Is it stable? FastMM4 has been with us since Delphi 2010. Maybe it's time for Embarcadero to take a look at improving the memory manager now that we have the Parallel Library. Or is this a "storm-in-a-teacup" and is FastMM4 perfectly adequate for most parallel applications? https://code.google.com/p/scalemm/

Parallel.For - What's the Best Way to Show Progress? I have a time consuming task which the new Parallel.For routine is ideally suited to. In a single thread environment I show progress using a ProgressBar which is updated inside the loop. I thought the parallel version would be a doddle - but it's not. If I update the ProgressBar using a TThread.Synchronize wrapper it becomes deadlocked. The main thread is waiting for the For loop to end, and the For loop need the main thread to perform the synchronized code.  This is something which was highlighted in a recent Coderage video. The second option is to update the code using a TThread.Queue wrapper. This works! However, it seems the progress updates all come once the main loop has completed (since the cores are busy doing the For loop). The third option is to call the Parallel.For loop as a TTask and use synchronize inside the loop.  This way the main loop isn't waiting for the For loop to end. This also works and the progres

So how about Embarcadero gets gutsy and adds a compiler option to require empty parentheses when calling parameterless functions and procedures. To me it's one of those things that has never made sense about the Pascal language, and makes it harder to read. And now, with function references, inconsistent.

How-To Guide: Upgrading Your Delphi VCL Applications To Support 4K Displays

Does any one know a way to see if a key combination (ie, ctrl-shift-w) has been registered as a global hotkey? I do not want to know which application, just if it has been registered or not.

Version 1.0.1 of DDDebug - the Delphi Memory Profiler - has been released recently. Registered customers can download the update for free. In addition to some smaller enhancements, this release significantly improves the performance of the profiler. Read more about DDDebug and download a trial version at http://ddobjects.de/dddebug

Hi guys . I had just finished implementing the new version of delphi detours library (v2). This new version was born from the scratch , and it's the same thing for InstDecode library. Many BugFix and new hooking architecture was introduced allowing support for multi hooks ! Whatever your hook was installed from your app process or via (dll,..).DDL v2 will manage your hook to run without problems . Beyond the multi hooks support, there are many new features : -VEX support . -Instructions Maping. -Hooking interfaces methods. -New function to detect if a function was hooked. -Three bytes escape table support. -I will try to cover the rest later. Before publishing the new version i need some beta tester to test the new version. If you want receive a beta version ..send me a mail to: ismspider at gmail.com https://code.google.com/p/delphi-detours-library/ https://code.google.com/p/delphi-detours-library

Anyone happen to know why all the memory management routines in Delphi take a signed rather than unsigned integer? Even routines that support 64-bit memory addresses use NativeInt rather than NativeUInt? A quick glance around the OS and language landscape suggests unsigned is the norm. Using signed integers unnecessarily limits the maximum size of contiguous memory that can be allocated and requires all those routines to check that parameters are not less than zero. Why would someone purposefully do this?

In a lot of common cases, handling memory for local variables with a try ... finally can be easily avoided, as soon as you care about the scope of the variable. We introduced some kind of automatic memory management to ease business code writing in our Open Source mORMot framework. Not perfect, of course, but definitively some syntaxic sugar to be used  on purpose, as a type saver. http://blog.synopse.info/post/2014/11/14/Automatic-TSQLRecord-memory-handling

It will be great if embarcadero do something like this, not for old users like me, I mean for new one. We need bigger comunity!

I am battling an intermittent error. According to EurekaLog, the error occurs in this routine: procedure TTreeItem.Clear; var   j: integer;   LinkedItem: TLinkedItem; begin   for j:=0 to LeafSize-1 do begin     if Items[j] <> nil then begin       if Items[j] is TTreeItem then begin <---- exception thrown here         TTreeItem(Items[j]).Free;         Items[j] := Nil;       end       else begin         LinkedItem:=TLinkedItem(Items[j]);         while LinkedItem <> nil do begin           Owner.DestroyItem(LinkedItem.Value);           LinkedItem:=LinkedItem.Next;         end;         TLinkedItem(Items[j]).Free;         Items[j] := Nil;       end;     end;   end; end; The code seems all too simple. Items added are TTreeItems, so the test for whether the item is a TTreeItem is almost redundant, but the question is, how can an is test on the item throw an exception? The code is taken from a Hash Trie implementation which is used in a third-party component, a version which is

Hi Guys, I am looking for books to get up to speed using Delphi or Object-Pascal for that matter. Any recommendations? Thanks, Daniel

Does anyone know of a FMX component to read UPC barcodes (the type you find on products in the supermarket and other stores)?   In addition, anyone know of a web service (free or otherwise), where you can look up products based on the UPC?   Thanks.

Hi there, I was wondering how you measure your software, I mean, how you know what the best feature of your software is, the feature which is less used, how often and for how long features are used and so on. I know there are surveys for that but if only 10% of the users answers then the answer is not meaningful.

Just realized you can run Delphi services (and many applications) directly on the Free Hyper-V 2012... anybody searched how allowed that is by the Microsoft license? I'm referring to using Hyper-V 2012 itself as a "bare metal" OS, rather than as a virtualization OS. You're limited to command-line, but that's quite okay to run db or web servers, and you can easily install alternative shell, desktop and administration tools if you really want a GUI. If allowed, this effectively brings the costs of hosting services that are Delphi-based rather than IIS-based to the same level as Linux. Also since the OS is bare-bones, it just runs more efficiently that a full-blown Windows 2012 and is less vulnerable.

We are pleased to announce the availability of the EurekaLog 7.1.1 stable release. EurekaLog is a complete bug resolution tool for Delphi and C++Builder developers that gives your application the power to catch every exception and memory/resource leak, directly on the end user PC, generating a detailed log of the call stack (with file, class, method and line number), optionally sending you a copy of each log entry via email or to a web based bug-tracker.

Like the "begin on enter" that is not always welcome, there's a menu option that could be very cool if it was not so designed so badly. It should at least extend selection to whole words (or line feeds), and reformat code after insertion.

Yeah... That's familiar :rolleyes Originally shared by Justin Lee How QA is done.

A colleague of mine spotted the weirdest XE6 bug so far. On an TMS TAdvStringGrid 1. for i := 0 to Grid.RowCount - 1  do Grid.RowHeights[i] := rh; 2. for i := 0 to Grid.RowCount - 1 do begin   Grid.RowHeights[i] := rh; end; Example 1 failed at setting all lines, Example 2 worked. Does anyone know of an XE6  QC or QP that is related to "missing" begin/end enclosures?

JCL & JVCL - What are the Real Gems in these Tool Sets I've just installed JCL and JVCL for the first time. I'm really quite picky about the components I use.  I generally stay away from free (due to the lack of incentive for the author to upgrade). However, JVCL seems a little different to the average freeware. It has strong community support and was upgraded to XE7 support really quickly. So I thought I'd take a look. Now I have installed it, I'm quite overwhelmed by the plethora or components. So... to all those experienced JCL and JVCL users, what are the real gems in this set of components / routines? What are the components you find the most useful? What are the components you simply cannot do without? Thanks - Steve #JCL   #JVCL

This is slightly OT... One of my "Delphi Heros" has its birthday today Dr. Bob - a lot of others and me probably learned Delphi also by his tutorials. Thanks for that and "Happy Birthday" ... http://www.drbob42.com/ http://www.drbob42.com

Can anyone point me to full tutorial or book or any other online resource towards database development with ISAPI . I am using xe6. Thanks.

Now that LogMeIn is a paid service with less features than the free version, what are you using to remote into a machine behind a firewall? I need to be able to get to my Delphi dev machine while I am on the road.

What would be cool is if freebies (Nick's book, Castalia, etc.) that are given throughout a release cycle applied to prior purchasers of that release version.  So for example if I purchased XE7 a week after release I'd get everything added to future promotions.  If I purchased a month before the next release I'd only get the promotional items for that promotion only.

I'm looking for tools or method how to determine what exactly packages are still being compiled into main application after enabling "use packages" option. This problem is related to this SO question http://stackoverflow.com/questions/1562601/determining-delphi-runtime-packages-to-include  but from a different angle. I know which packages the app depens on (thanks to Project Info, Required tool http://cc.embarcadero.com/Item.aspx?id=18561 , Dependency Walker, etc), what I need to know - what packages are inside the app - to further decide what to do about it. Yet another angle of the problem is lack of information what package which unit belongs to. I don't see this neither on official docwiki page, nor in installed help system. Am I missing some simple clear solution to both these problems? Anyway I'm going to file a bug or two ;) http://stackoverflow.com/questions/1562601/determining-delphi-runtime-packages-to-include

I am testing my REST Server and found a Chrome Extension "Advanced Rest Client". With Delphi I can test the functions/methods by using the HTML Server Function Invoker, sending parameters and watch the result. That server with be used by a Java Client, so the programmer asked how he could test it using the Chrome Extension. I tried to use passing some parameters but the server function themselves won't work, I just see the page loading without error, but no result. How do I inform my fellow about using Delphi Rest with Java?
