I'd be curious to know where Delphi compilers fall on the scale. Originally shared by Greg Kroah-Hartman This is a great step forward, sure it might not perfect, and static code analysis might be better if you have access to the code, but you can learn a lot from binaries and it's really revealingly the choice of build tools that a project uses as an indicator of the "smell". https://theintercept.com/2016/07/29/a-famed-hacker-is-grading-thousands-of-programs-and-may-revolutionize-software-in-the-process/

Anyone know of a component or tool to help us quickly make a visual query builder, for Win32 desktop Firemonkey? We need to make simple select statements from a fixed list of tables, the ability to select specific columns and provide aliases for them is important, and we need a reasonable level of flexibility with the WHERE clause (filtering and grouping). Given how much of what we want to do is 'on rails', we could build a complicated dialog with lots of dynamic clauses and what have you - but time is of the essence and money not necessarily a key factor. There are a number of these kinds of things for the VCL - but the rest of our project is FMX and I'm not sure I want to try and get a VCL component shoe-horned into an FMX app (though I may look deeper into that).

Delphi class for WinSparkle Hi guys, I've written a class for WinSparkle (a Win version of Sparkle for OSX). Have a look here: https://github.com/jkour/neSparkleComponent Let me know what you think. Thanks. https://github.com/jkour/neSparkleComponent

I want to integrate my Delphi DX10 application with Sketchup. My application is a Product Configurator, at this moment specialized in furniture industry. What I need is create a .skp file with the piece of furniture currently editing on my application and after open this file with Sketchup. The user can make modifications in Sketchup and after close it my application will modify the data of the piece of furniture, accordingly with the modifications in sketchup file. I know two ways for treat of do this. The first consist in create from my app, a script in Ruby that I can pass as parameter to Sketchup. This sounds well but the problem is about select a format to export later the modified project.

Stack Overflow: What is your experience with Stack Overflow? What can you say about why you would rather post here, instead of posting on Stack Overflow, where you have a much broader audience? I can say: they don't allow any errors (or mental "fog"), if you misread something in a duplicate post and even though somebody helped you easily in your post, just a one liner helping you out: somebody comes and says you missed this! You have an all out war because "I answered that in this post years ago! How stupid are you! Now we have a duplicate, damn how could you" Not even entertaining the possibility that somebody else had the same "error in their mind's compiler/ fog", which lead them to think of the problem differently, which means the duplicate I just made does in fact god forbid have merit. And it's not about the fact that I made a duplicate, that's fine, it's the fact that I almost feel the super users take offence if you didn't ...

Today I've tried to recompile a Seattle FMX App with Berlin. The Android version compiled succesfully in 5 minutes or so (a very smooth transition), but when I try to deploy it to my iPad (iOS device, 32 bit, debug configuraton) I have no success at all (the same exact project deploy on my iPad under Seattle without errors). This is the error I got before the linking phase aborts, any help?

I've written a Delphi class which I am going to put on MIT license on github. The class is a wrapper for a DLL, which is another open source project. That license says that I can use, modify, etc etc the code. My question is whether I am obliged to use the same license terms since I am only using the final compiled DLL and not the source code.

SO, I think I'll be able to figure out what to do with the actual laying down /or drawing/ of the candles... the important / actual question part: ... What I need help with is (almost the sam...

Hi guys, I am still working on that DLL compiled in VS2015 and I have this declarations in the DLL: void __cdecl newProc(newProc_callback_t); /// Callback type typedef void(__cdecl *newProc_callback_t)(); Now, how do I get access to this?

I am pretty sure I mess something up with the pointers. Can you help please? Thanks.

I am trying to use a DLL from Visual C in D10.1 and the declaration is this: void __cdecl setProperty (int state) I have declared my procedure as: procedure SetProperty (const autoCheck: Boolean); var tmpProc: procedure (state: NativeInt); cdecl; begin //Here I load the DLL in another procedure and keep the handler fHandle @tmpProc:=GetProcAddress(fHandle,'setProperty'); if Assigned(tmpProc) then begin if autoCheck then tmpProc(1) else tmpProc(0); end; end; When I debug the code, tmpProc gets an address, which I think means that setProperty is loaded from DLL.

Ahh ! I hate losing time on such "conneries" ! on a computer with 2 network cards, I had a Delphi/Firebird application that works perfectly and a second one that raise an "Unable to complete network request to host 192.168.13.1". The first application uses the IBDAC components, the second one uses IBX. It took me hours to understand that the only real difference between them is that IBDAC save the default port value (3050) while IBX do not. The 2 network cards had nothing to do with the problem, but there's a local firebird instance configured on port 3055, and this #$@ fb client tried to connect to a remote host with the port from the local server configuration !!!! C'est du grand n'importe quoi (in good french) someone to go whip the developer who did that !

Thomas Mueller As a comment to your recent blog article. The way SQL Server treats converting string to datetime is determined by its dateformat setting. See https://msdn.microsoft.com/en-us/library/ms189491.aspx And I think the defaults are in fact ISO-8601 according to this article: https://msdn.microsoft.com/en-us/library/ms186724.aspx Be careful though with changing it as you might horribly break something.

Does anybody have a version of Delphi Detours ( https://github.com/MahdiSafsafi/delphi-detours-library ) that works with Delphi 2007? Version at the githib claims to work with D2007, but it doesn't compile as it uses few language extensions that were introduced after D2007.

It has happened a few times in the past that I have generics that are constrained to only have interfaces as generic type parameters but only work when the interface type has a guid. Constraining on interfaces works but not on having a guid (I usually solve that by checking that at runtime and throw an exception with an appropriate message). However wouldn't it be so much nicer if I just could not compile such code because I can apply an additional constraint? https://quality.embarcadero.com/browse/RSP-15549 Now imagine if generics would also work for standalone routines and we could have a fully type-safe version of Supports that would look like this (yes, I know you can put that into a class or record to make it work): function Supports (const instance: IInterface; out intf: T): Boolean;

Has anybody an idea where I can find more detailed information on the security implications of wrapping a 32 bit dll in a 32 bit out of process COM server to be able to call the DLL from a 64 bit application?

I've seen others suggesting using a later version of the NDK for compiling for Android. I attempted to use NDK r12, however the resulting executable crashes (causes a SIGSEV) in _StrUInt64Digits in System.pas (called from GetICUVersion in ICU.inc) when the app is starting up. This is using Delphi 10.1 Berlin on a Samsung S7 Edge. Has anyone managed to successfully use a later version NDK?

Q: Is there a reason to move my Windows 32-bit application from XE2 to XE10? I recently received a sales call from Emb, asking me to upgrade to XE10. I wasn't sure how to respond, as I haven't evaluated it since XE7. However, I was under the impression that my source-code didn't have a lot to gain from it. I say this, because the product's market is Windows and I don't want to invest the dollars into it to optimize the code to use Generics or Anonymous Functions for no real reason. Don't get me wrong, it's not that I don't think other people have a use for it. Perhaps 64-bit would be useful, as a sales-tool, but I don't need large memory support for it to run. Emb mentioned WinRT mapping to the VCL, which sounds interesting, but I honestly don't know how I'd benefit from it.. is Win32 API targetted VCL applications going to be unsupported in Windows at some point in the future? So tell me, why do I need XE10 over XE2 for non-mobile developme...

We updated the public trial version of TRichView to version 16.8. Main changes in this update include: - special colors for odd and even groups of table rows, heading rows, the last row; the same for table columns - widow/orphan control (avoiding page breaks before the last line and after the first line of paragraphs) - special objects for storing additional information in documents - applying styles from files to documents. We also updated our installer, it now supports installing optional packages, and we used this feature to install packages integrating our components with other third-party components (Addict 4, ReportBuilder 17, THTMLViewer, DeveloperExpress VCL). Also, it now uses the more traditional package scheme (runtime + designtime packages). The source code of the installer will be available soon. By the way, we created an utility for package generation: by the specified lists of units, dcr files and required third-party and standard packages, it generates packages (compati...

I am running a Delphi app as a seamless remote app. I am sure that I have read in the past that VCL applications create a 0x0 hidden window as well as the main application window. I think it is related to the TApplication object. If this is the case, it would explain why I have two windows showing on the task bar each time I run this app. One shows, as it should do the app name. The other just shows (remote) with no other name and there are only two options available (minimise and close). Closing it closes the main app, so I am sure that they are related. Is there any way to prevent this and only show the main application window?

Delphi reports in the output window the dcc32 commands needed to do the build. I need to copy that collection of strings and use it myself to drive dcc32 from a separate app, so I can log the output of the compiler, with time stamps. As it turns out, that is more challenging than expected. The collection of strings is large, and I have yet to convert them into a single long string which dcc32 will accept. I note in passing that dcc32 also complains of file names that are too long. It seems to have a limit at 260 characters. But perhaps that is an old Windows limit. Anyway, if anyone has gone through this process successfully, suggestions would be welcome.

Hello guys, Is it a good idea caching calls to Length(Array)?

Hello guys, Is there binary literal support in Delphi? I mean I can express numbers in binary way and it is resolved at compile time, something like this: 0b00000100 from C#7 and C++14 When I am still able to use hexadecimal representation, the binary way is a lot more representative when creating bitmasks and doing bitwise operations. For example, when you want to extract GIF metadata, you will have to parse the Logical Screen Descriptor block, and it needs some bitwise operations to extract fields in the packed fields byte. Instead of writing this: $80 -> 1000 0000 ~> this mask will check if the file contains a global color table $07 -> 0000 0111 ~> this mask will extract the size of the global color table The binary representation is more aligned with the file documentation, since GIFs are binary files (this also apply to many other binary file formats), and looks much better to understand at the first time you see the code. I would love to see a way to write my masks in...

I'm sending STRINGS( querys ) to the server: Ex1: ( INSERT ) Insert Into oses_pecas ( codigo,CODIEMP,CODIOS,CODIPROD,VALORUNIT,QTDE,TOTALPROD,OBS1,TIPOOS,DESCRICAO,CODICLI,VALOR_REAL,DATA,CODIFUNC1,DEVOLVIDO,CODICATEGORIA,PORTA ) Values ( 147117,1,67801,46,13,1,13,'C VERD',2,'FILE 2',10,13,'19.07.2016',2,'N',0,'\\RAFAEL-PC\TM-T81' ) Ex2: ( UPDATE ) The server show me this error: #unit: FireDAC.Comp.Client #erro: [FireDAC][Phys][FB]Dynamic SQL Error SQL error code = -104 Unexpected end of command - line 2, column 52132555 What can I do ?

Currently "fighting" trying to obtain a good codegen (for speed) on swapping dynamic array items (Int32, Int64, Single etc) in both cpu x86 and 64bit. The typical asm xchg trick to swap two integers does not help too much. var X : Array of Integer; // Int64 ... ExchangeItems(X,23,45) // X[23] X[45]

This code procedure Foo; var arr: TArray ; d: Double; begin for d in arr do ; end; Produces this hint: [dcc32 Hint] Project1.dpr: H2077 Value assigned to 'd' never used Anyone know a good way to suppress the bogus hint? I would prefer keep using a for/in loop rather than a classic for loop, but I'm beginning to feel that the classic for loop is the least painful option. I want to use the for/in loop because in various other places in my code I use the for/in and use the loop value and want to have consistency across related code blocks.

Hello! Suppose you have a generic type such as this: Type TMyGeneric = class End; Can you declare a "class of" this thing? Does anybody know? Thanks :) A

Related to Delphi (bear with me) I need to create programs for our work (in house) mostly database and soon (I hope) with android as entry devices. We have mostly 7, some XP and 8.1, x32/x64 What advice can you share about using windows 10 instead of 8.1 to use Delphi? I ask because I see a lot of Delphi developers sharing videos and screen shoots that shows w10. I think that the majority will need to use w10 because they need to be on the current windows platform and maybe because they like it. I don't want to stir a war. And I really want to be aware of the issues that as a Delphi developer you need to fight almost daily with w10, maybe you have seen forced reboots, hangs, incompatibility issues with compiled application in w10 that occurs in previous windows versions (xp, 7, 8.1) Have you seen problems in W10 with Delphi (Seattle, Berlin): crash, hangs, activation issues, that hopefully don't occurs in 7 or 8.1? Or maybe you have seen an improved stability of Delphi in w10? ...

Berlin, my first VCL project, a couple of forms and a dozen of frames, nothing special except a good sensation with this (for me) new IDE. Today Code Completion suddenly stopped working. Any other project that I have opened so far has nothing to note about it: pressing Ctrl+Space is perfectly operative. Nothing helped have moved the project in another, new, folder or deleting all project accessories files except dpr file: any help?

I continue to explore in a large legacy project, hoping to puzzle out something more about unit dependency cycles. Specifically, the problem is in trying to find which units are actually causing the issue, and which are simply along for the ride. There is a very good reason to want to find this. The problem is in getting buy-in to proceed, when after hours of work, there is little measurable benefit. Yes, I can document the number of such cycles removed, but the real issue is impact on build time, and if I can't show a significant improvement, then the casual of cost/benefit is rather negative.

One thing I miss in the FMX form designer, are the guide lines that assist with aligning visual components. VCL(which is older) has them, but FMX does not. Surely this would be a good addition to FMX or am I the only one that misses them?

I try to compile my project for android. The project uses Spring4D and works fine under win32. When I try to compile it under android I have a problem with compilation of Spring.Collections.Lists unit. Compilator error: [DCC Error] Spring.Collections.Lists.pas(269): E2003 Undeclared identifier: 'Event ' [DCC Fatal Error] Spring.Collections.Base.pas(2310): F2063 Could not compile used unit 'Spring.Collections.Extensions.pas' I attach a screenshot of my Delphi XE7. Please show me the way.

Hi All Could you tell me how to connect MySQL Database located in my Webhost, i have Host and i create 1 Database in MySql, i need to access that Database from my Application over internet, can you tell me how to connected ?

question to the group: Does this: https://en.wikipedia.org/wiki/Year_2038_problem affect Delphi's tdatetime (or tTime) or similar (for 32 bit) ? https://en.wikipedia.org/wiki/Year_2038_problem

Today I went to a twice monthly event not far from where I live called "code and coffee". About 70 to 80 people show up, separate into interest groups (Java, javascript, python,...) then discuss and code apps. I was sitting with a bunch of 20 and 30 somethings and mentioned I use Delphi everyday at work. They had no idea what Delphi was (one of them said he might have heard about it in the past). I had to explain to them what it was. At first, they sounded excited, when I told them it can be used to create multi platform apps. Then they asked what it cost...when I told them what it cost to be able to write those apps, they were sort of shocked. Then they looked up Delphi jobs on Indeed and Dice, for the local market, and completely lost interest.

procedure TForm1.Button1Click(Sender: TObject); begin try Form1:=TForm1.Create(nil); Form1.ShowModal; finally FreeAndNil(Form1); end; end; //--------------- everything works just fine at the first time when i click the button when i close it and click the button again i get access violation error at adress 00DB047D ... there is nothing in the OnCreate event for the Form1 ... i checked the form if it nil after close it it's says nil i don't know what i'm doing wrong ,for the record everything was working normal before

Hey guys could help me with doubt , please which the importance of onCreate and OnDestroy events in DataModule thanks to all .

Made with Delphi, startet with BP 7.0 My first pascal was TP 3.0 on CPM. Some parts of these Project are more the 25 Years old and compiles in XE7 in the last half year there was a big refactoring. Using now Spring for all Lists, etc.. The graphics part is opengl.

Sorry for the noob question. I'll do my best asking this. How the best way to return the focus to the visual component responsible for a data field that raise an exception in data validation? I made a detailed example of what I mean by that: https://gist.github.com/dipold/7c75821fba7a10ec1dad6620b8fcd141

Memorabilia...

consider TBase = class public const Snafu = 1; public type TInnerBase = class Foo:Integer; end; public procedure Bar(const Inner:TInnerBase); virtual; abstract; end; TDerived = class(TBase) public procedure Bar(const Inner:TBase.TInnerBase); override; end; procedure TDerived.Bar(const Inner: TBase.TInnerBase); begin Inner.Foo := Snafu; end; It nags me that I have to qualify TBase.TInnerBase, while I do NOT have to write TBase.Snafu; I wish I could drop the TBase. qualification part for types as well.

Are you interested in using OTL on mobile platforms? On OS/X? With Firemonkey? We need your input.

Just looked at it (not in depth) but hey it has Pascal too (and LOTS of other languages) https://www.codingame.com/start https://www.codingame.com/start

Hi All I need to Generate Report from Table and send email to system assign email address can you help me how to do that in Delphi XE8 with MS SQL Database

How would I be able to make my "tab stops" user selectable? I am writing to a dot matrix printer using Epson Esc- codes. write(F,#27 + 'D' + #7 + #23 + #46 + #61 + #0); // Set horizontal tabs How would I change this code to make one or more of the tab stops "variable"?

Method body from TStringBuilder (Berlin): function TStringBuilder.Append(const Value: string): TStringBuilder; begin Length := Length + System.Length(Value); Move(PChar(Value)^, FData[Length - System.Length(Value)], System.Length(Value) * SizeOf(Char)); Result := self; end; Function Length(Value) is called three times. Is it better would be if string length was calculated once and stored in a local variable?

Andreas Hausladen is it possible that this bug has something todo with your System.ByteStrings for 10.1 Berlin ?

Can we please get a few more upvotes for this feature request? https://quality.embarcadero.com/browse/RSP-14867 I know we discussed this already in another post but I think this feature is really nice and will lead to cleaner and more robust code. What I expect: - exact same rules as with initializing global variables with one exception: the initialization will happen every time the routine is called - initialization should happen during the prologue of the routine just as it happens with initialization of managed types variables (like strings, managed records, interfaces, ...). Before you come up with some made up code example and how it would make things harder to read, understand or debug: please make sure the code you post would stick to the rules I explained above because if it does not we don't need to discuss it.
