TADOStoredProc problem in Delphi 10.1 Berlin ? I think I might have a problem. I am firing a stored procedure on SQL Server 2012 using TADOStoredProc ( proc.Exec ). The original code was written in Delphi 5 and was sat inside a try .. except and when / if the proc failed the exception was handled: try .. proc.ExecProc .. except on e:Exception do begin WriteAndForwardError( format('%s',[e.Message]) ); if adoConnection.InTransaction then adoConnection.RollbackTrans; exec_failed := true; end; end; but now the same code ( ported over with minimal changes ) does not raise an error and I know it should be throwing back a Foreign Key Exception for FK_23. I have tested it on the old code base and same data in D5 causes this exception, but in D10.1 this exception is not happening. Has anyone else seen this behaviour or is it just me

Why I get error? Result is really undefined?

http://www.andreamagni.eu/wp/2016/05/meeting-ositalia-2016-summary-and-pictures/ In person meeting in Italy, last friday. #Delphi #Berlin http://www.andreamagni.eu/wp/2016/05/meeting-ositalia-2016-summary-and-pictures/

Apparently Delphi 10.1 Berlin no longer supports iOS 7.1, which is a problem for me as a number of my users are still on iPhone 4. I've changed the min version in the linker settings to 7.0, which allows it to install but it terminates before launching the main form without an error (basic app, empty form). I assume this is deliberately coded within the FMX framework somewhere. Does anyone here know how to work around this to get a Berlin app running on iOS 7.1? Thanks!

TInterlocked.Exchange for interfaces? Since there is no System.SyncObjs.TInterlocked.Exchange overload for interfaces (and the Exchange version is stupidly enough constrained to class - thanks copy paste from C# where the class constraint means any reference type!) I was wondering how to properly implement it for IInterface. Is this correct? class function TInterlockedHelper.Exchange(var Target: IInterface;  const Value: IInterface): IInterface; begin  Result := IInterface(Exchange(Pointer(Target), Pointer(Value)));  if Value <> nil then   Value._AddRef;  if Result <> nil then   Result._Release; end;

Hello guys, Is there a way to do UI Testing on FireMonkey? I mean something like this https://developer.android.com/training/testing/ui-testing/index.html or this https://developer.xamarin.com/guides/testcloud/calabash/introduction-to-calabash/ :D https://developer.android.com/training/testing/ui-testing/index.html

Hello I have been programming in Delphi and Builder since version 6 (occasionally). I have for some time seen the expansion of C #. And I have a question, basically a few. Is Delphi still worth to program in. there is no free version, and the cost of purchase is quite big (in Poland). – C# I can get for free . lots of components is translate to C#. ok maybe Delphi has more database support. But, stay in Delphi or move to C#.

The IDE Fix Pack 5.95 for RAD Studio 10.1 Berlin is released. There is also a IDE Fix Pack 6.0 BETA 3 available for those who want to test the experimental 64 bit compiler performance optimizations. http://andy.jgknet.de/blog/2016/05/ide-fix-pack-5-95-for-delphi-10-1-berlin/

Thanks to Gerrit Beuze (ModelMaker Tools) I'm at moment on a big refactoring of a legacy Delphi program that was developed in the last 25 years starting with BP 7 or so. What i can say now (the biggest work is done) that without MMX (Modelmaker Codeexplorer) it had been be a nightmare. I can only tell everybody check it out. In my sight it is one of the best tools ever made for Delphi. And i'm only a customer.. http://www.modelmakertools.com/code-explorer/index.html http://www.modelmakertools.com/modelmaker/index.html

anyone using audits and metrics in Delphi? I'm in a big refactoring process und this would help to see the problems in the code. the project compiles at moment without any warnings and hints. 1 million lines of code. now try to use the audits and metrics. but it hangs always (Xe7) and Berlin. Is these feature really a enterprise feature?

Thanks Andy! http://andy.jgknet.de/blog/2016/05/ddevextensions-and-dfmcheck-for-10-1-berlin/

Is there any Firemonkey specialist here ? I just want to change an background color of an item ! I've already check Emb samples but there is nothing about styling listview items.

Displaying huge text files Sometimes programmers have to deal with larger than usual text files. Examples are log files or XML dumps of databases. For my tests, I used a dump of the English Wikipedia in XML format. This file is 48 gigabytes in size and as I found out only today contains 789,577,286 lines of text. http://blog.dummzeuch.de/2016/05/29/displaying-huge-text-files/

I really want to thanks David Millington, Bruno Fierens and all the guys which shared information about plugins development and info about how to extend the IDE. My first steps in this area wouldn't be successful without your help. Your help and that of the community! For now I use only standart or made by me components and the IDE(Berlin) works fine, fast and really better than my expectations. Also... I want to say something (although sometimes I am too critical for bugs) - according to me this is the best version of Delphi till now. I really really like to work with "Berlin". It is just cool.

Hi. Does anybody have any experiences with Delphi+SOAP +x509 certficate ? Web service needs soap envelope with header like in file here https://www.dropbox.com/s/4ovt9zgoo9zt9ns/soap.xml?dl=0 How to generate it in delphi ?

Can someone help to understand the advantage, if any, when using CreateAnonymousThread or Task? Can be my impression only, but Task seems to be slow?

The Delphi-event-bus library (publish/subscribe Event Bus framework) by spinettaro deserves more popularity - it's thread-safe, it's simple yet flexible (I meant it), and supports async messaging. From what I know, I can say it's the only one of its kind that supports all the above mentioned features. https://github.com/spinettaro/delphi-event-bus

There seems to be a natural tendency to post about bad experiences and problems with new Delphi versions so I thought it'd be nice to post about my successful journey into #10.1berlin. I have a mobile app which contains most of the standard features such as ads, inapp purchases, REST services etc which was originally written in XE5. Since then I've been able to install the new Delphi versions, load in my project and run without any major issues. I was happy and my users benefited from the new features and on the whole it was good! Sadly this came to an end with the unstable mess that was 10Seattle... I recreated my project, rewrote bits according to the "new ways" as declared by EMB and yet the built apps crashed without warning, were slow and just painful. I remained stuck on XE8, patching to keep it working on the latest devices and iOS versions. Thanks to the amazing quality initiative at EMB, 10.1 Berlin is epic! I've just finished the testing cycle of my app

I have just uploaded a first beta of Package Magician, a plugin to handle project specific packages inside the IDE. If anyone is interested trying it out please join this Google Space: https://goo.gl/spaces/JuFpwWkXqugXkLCv6

Did a minimal installation Delphi 10.1 Berlin and added features afterwards. Now I found 15 GB of packages in $(BDSCatalogRepositoryAllUsers). What for are they left and why not removed after installation ? I have another installation where this folder does not exist although it is a full install.

Hello Folks, I just uploaded a new version of the Delphi IDE Colorizer (DIC) plugin with support for RAD Studio 10.1 Berlin.

I've been working on a simple Firemonkey app in Berlin 10.1 to load an image from a web service using IdHttp.Get() into a memory stream and then loading that into the a TBitmap. It works great on iOS and Windows but on Android it seems to fail on img.LoadFromStream(). It isn't raising an error, it's just not going any further but that might be a debugger issue (I've had a few with Berlin). Does anyone know of problems doing this on Android or is there something I'm not setting/converting/encoding properly? Thanks The code is: task:=TTask.Create( procedure () var ms: TMemoryStream; png: FMX.Graphics.TBitmap; http: TIdHttp; begin png:=nil; http:=TIdHTTP.Create(nil); ms:=TMemoryStream.Create; try try ms.Clear; http.Get(url, ms); ms.Position:=0; png:=TBitmap.Create; png.LoadFromStream(ms); if fBannerImage = nil then fBannerImage:=

After spend a full day trying to build a open project on BERLIN, and fail every time with cpu going to 100%, im coming back to Seattle. Same projects just works on Seattle. No delay, no problems, not HIGH CPU usage. As Nick Hodges says, we hope have a IDE FIX pack soon. Nobody will pay the time i lost testing this, BTW. EMB, please, do the job. If you cannot do the job HIRE someone else, but fix this. In my experience Berlin FAILS on big projects, and based on the past experience will only be fixed with a FIX PACK like Andreas Hausladen produce in the past (like the one Seattle already have). Game over Berlin. Edit: after the release of Andy fix pack and comparing the use for a week I see Berlin work fine. For the records.

Known IDE Packages in Delphi Prompted by a comment Jeroen Wiert Pluimers 's Google+ post I had a look at what is actually listed in [HKEY_CURRENT_USER\Software\Borland|Codegear|Embarcadero\BDS|Delphi\#.0\Known IDE Packages] and found some interesting entries http://blog.dummzeuch.de/2016/05/26/known-ide-packages-in-delphi/

Anybody know what happens to DEVRACE (FIB+ developers)? The site is up, the forums are un managed, not new announces or updates. I believe it happens at the moment EMB buy ANYDAC, but not sure. The question is, how is possible a company as this let the users alone in the dark (great game)? Thanks god they release components with source.

My boss won't let us move to Berlin until there is a FixPack for it. We have a very large app, and the Fixpack literally saves us hours a day. Andreas Hausladen -- We'd love to have a FixPack for Berlin and going forward. Can we entice you to do it? Would a non-trivial donation help? Can we eliminate any roadblocks or hesitations you may have? As a side note, have you considered becoming an MVP? Sorry to be so forward, but we really can't work without the FixPack.

We're pleased to announce the availability of TMS FNC (Framework Neutral Components) UI Pack v1.1.0.0 with 3 new components! - New: Introducing TTMSFNCTabSet and TTMSFNCPageControl - New: Added database support for TTMSFNCPlanner via the TTMSFNCPlannerDatabaseAdapter For more information visit the product page: http://www.tmssoftware.com/site/tmsfncuipack.asp

Some news on the "Different Package Versions per Project" issue. Assume we have different packages each containing TMyComp with differences in the available properties. We have a project group with projects A and B. Project A uses version 1, while project B uses version 2 of TMyComp. We are working on project B with a form open containing an instance of TMyComp which has some of the new V2 properties set. We switch to project A, unloading version 2 of the package and loading version 1. The IDE nicely closes the form with the V2 component, but keeps the PAS open. Now switching to design view throws an error regarding those missing properties. Here the only option to keep things intact is to Cancel. Switching back to project B unloads V1 and reloads V2. We can switch safely to design view now and all the properties are as expected. So the only critical point is the reaction to the missing properties dialog. One has to Cancel, otherwise the DFM will be screwed. Would that be acc

Originally shared by David Berneda New "Dynamic Filter" class and editor dialog. All tables and fields related (master-detail linked) to any data or query are shown on a tree with their individuals values to check / uncheck the desired ones. This automatically creates a "filter expression" that is applied to the output data. Date-Time values have an special subdialog to choose the range to filter (ie: "Last Month", and / or "Thursdays and Saturdays" etc) Output is refreshed "live" in milliseconds to any control using the data (a BIGrid or BIChart etc). The BIQuery editor includes this Dynamic Filter for a really-visual way to create queries and pivot-tables without sql or code.

Originally shared by David Berneda Big improvements in BIChart control. Support for design-time has been accomplished and its now much more smart in determining what data to choose and how should it be plotted, in a totally automatic way. Of course, every setting can be customized manually or by code. The automatic recognition so far is capable of: -Deciding if the data (tables, subtables, etc) can be plotted using a 3D style (surface, contour etc), Financial (candle), Geographic (world maps) or 2D (XY). -Based on the above, choose the "best" series class (Line, Bar, Point, etc etc) depending on many factors, like number of points, data range, etc. -Determine the best style orientation (horizontal or vertical) -Determine the best data direction (by rows or by columns) -Choose an "stacked" mode automatically (stack, 100%, overlap, self-stack etc) -Choose the "best" columns / fields to use for chart data and axis labels -For 3D, plot values as "XYZ"

If you ever wonder why you get no (or incomplete) RTTI from a control that you inherited from a DevExpress one - then look into cxVer.inc where it has the following lines: {$IFNDEF CXTEST} {$WEAKLINKRTTI ON} {$RTTI EXPLICIT METHODS([]) FIELDS([]) PROPERTIES([])} {$ENDIF} Martin Wienold was wondering (and so was I at first) why he could not properly resolve a form from the DI container that inherited from TdxRibbonForm despite writing a public method with [Inject] attribute on it but it was never called. Warning : If you are using DevExpress or any other source code that does this (changing the $RTTI directive) and build these sources together with your application (in contrast to using precompiled dcus or even packages) on a version http://qc.embarcadero.com/wc/qcmain.aspx?d=79943 which causes RTTI to disappear even from units that did not have the $RTTI in them.

FMX disables floating div by zero exception. VCL does not. Is this intended? procedure TForm20.FormCreate(Sender: TObject); var i: Integer; tmp:Single; begin Caption:=Default8087CW.ToString+' '+Get8087CW.ToString; i:=0; tmp:=10/i; end; Some debugging shows this happens at System.Win.InternetExplorer initialization and also at TCustomCanvasD2D.TryCreateDirect3DDevice procedure. FMX sets 8087 control word to $137F, while VCL sets $1372

TSortedDictionary and other enhanced Generics I looked around finding a similar generic as the .NET SortedDictionary. There is a rather old open source area https://github.com/ghquant/delphi-coll . But of cause I would prefer to use a well maintained standard library being part of the Delphi core shipping. Are there any plans in that direction?

Is there an equivalent for the .NET ManualResetEventSlim in Delphi somewhere that I don't see? I am asking because I wrote something similar a while ago that I needed for my thread based coroutine implementation (for platforms that don't support fibers - i.e anything but Windows).

This is most likely more a question for Marco Cantù but does anyone know what is happening with AppWave? Is it still going, or has something replaced it?

Hi all I'm having a problem with FMX TListView in Delphi 10.1 when applying styles. It works find when the stylebook is first applied on app launch, but my users have the option of changing to a Dark theme, which switched the TStyleBook on the form. This worked fine in XE 8 but in 10 Seattle and 10.1, it doesn't refresh the TListView background colour, so ends up with white-on-white until the users close the app. I've tried calling NeedStyleLookup and ApplyStyleLookup on the TListView to force it but still nothing. Has anyone else had this problem or know how I can refresh my TListViews after switching stylebook? Thanks!

What is "zoom level" to you? Is there a universal answer to this, which I have ignored? * Would you think that a 2000x2000px image zoomed out to 50% should show 1000x1000? * Or would you consider zoom level to be related to the area, i.e. a 50% zoom would show 1414x1414px view?

I know it's deprecated and frowned on like crazy but I really need TClientSocket installing in my Delphi 10.1 Berlin. Where do I get it from ? Or is it still somewhere in the libraries on my hard disk ?

How to make TComparer work with Proc or Pointer? TComparer .Construct( function(const Left, Right: TProc): Integer begin Result := TComparer .Default.Compare(Integer(@Left), Integer(@Right)); end); https://gist.github.com/dipold/99e47c218f3986fd5c2e71bc4fadecd8 https://gist.github.com/dipold/99e47c218f3986fd5c2e71bc4fadecd8

I have an odd bug on FMX that has all the hallmarks of a pointer overrun or something similar, writing pixels to a FMX TBitmap. It only occurs on some machines with a specific OS/hardware combination; I can't reproduce it; I can't reproduce even on the same machine with a test cut-down app; a code inspection shows nothing wrong, compiling with range checking etc is fine, as are bound-checking asserts. My customer is in the process of setting up remote access to the machine it occurs on, but I'd appreciate any "Yeah, you're clearly doing X" kind of help :) http://stackoverflow.com/questions/37325579/odd-artifacts-writing-to-fmx-bitmap-with-tbitmapdata-on-windows-10 http://stackoverflow.com/questions/37325579/odd-artifacts-writing-to-fmx-bitmap-with-tbitmapdata-on-windows-10

Question regarding Berlin's GetIt and VirtualTreeTurboPack... The description says"Please insure that VirtualTree 5.5 is not installed before..." Does apply only for Berlin? I have older versions of Delphi with VirtualTree installed.

TRectF.Scale and TRectF.ScaleCentered missing? I find myself often rescaling TRectF. It's easily done, but I'm surprised that there are no functions for this in TRectF. Did I miss something?

Another day in paradise... So I switched from DisableControls to using BlockReadSize because FireDAC relies on TDataSource for controlling master/detail relationship (which DisableControls then promptly breaks). And today I found that if TClientDataSet has a TBooleanField, that field will not update on scrolling if BlockReadSize is >=1... Integer and string fields have no issue, but the boolean field is not updated. Oh the joys... XE6 FWIW

We just finished creating a set of videos showing how to create master/detail reports in our soon-to-be-released components Report Workshop. Several videos showing how to create two level reports using different ways, and a video showing how to create a complex report (linked to this post). All these videos use SQL (a basic knowledge of SQL, at the level select A from B where C = D group by E, is needed). There are other ways to make master/detail reports (using TDataSetField, or using a relation between data sets established in an application) that are not shown. http://youtu.be/wpvGlvL20GU?list=PLAJhRwXOW5tEQO3P3ytHlJSB4UxTBmxYc

I am looking for a FMX component which creates tiles or panels like those you see when you have a big number of images in a folder. The requirement is to be able to scroll vertically and change the number of columns depending on the width of the window. Does anyone know any such components? Thanks

[Feature Request - New syntax : Declare local variables with value - https://quality.embarcadero.com/browse/RSP-14867 ] Since we can already do this (for global variables): var Variable: Type = Value; And this : procedure Example; const Symbol: Type = Value; begin // code end; How about this syntax? procedure Example; var Variable: Type = value; begin // code end; This would only initialize the variables that are specifically assigned a starting value. When applied to managed types (string, interface), this syntax can also avoid the otherwise automatic cleaning of the stack, since this syntax already assigns a value to these variables. I would expect an initialization each time the function is called. (In this regard, it's a bit similar to default argument values - https://quality.embarcadero.com/browse/RSP-13289 ) Dynamic arrays can already be initialized from declaration since XE7, I think it could get expanded to other types as well :D

I'm testing the FMX TTabControl of Delphi to see if I can get it to work nicely on Android and iOS. I have a few tabs, which each having a TListView and I'd like to change tabs by swiping sideways in the same way as Android's app store does it. Apparently you can do that with gestures, but I'm looking for a solution where the user can already see the tab scrolling during the swipe. The effect I'm looking at is the same as if I'd add three TListViews on a TScrollBox. However, all the vertical swipes would scroll the TListView and all the horizontal swipes would go to the TScrollBox. Does anyone know of a tabcontrol, which would already do that or alternatively know how to prevent the sideways scrolling of the TScrollbox when the user has started to scroll the TListView?

I was just looking at TList.Grow (and TStringList.Grow) and I realized that the numbers are a bit odd - is that intentional for some reason? When adding 1024 items it grows like this: 4, 8, 12, 28, 44, 60, 76, 95, 118, 147, 183, 228, 285, 356, 445, 556, 695, 868, 1085 When using TList the growing is exponential (as it is the case in the .NET List ): 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 I know that if you know the count of the items you want to add it is better to preset the capacity - my question however is what implementation of grow would be better as a default? Or are there even better ways like growing in fixed steps based on the current capacity?

Do you use GetIt?

What the what? Why would a function retain the value of a previous call to the function? I finally got some old D5 code that operates on Tstringlist members to work in Berlin/Unicode but... It is a non-sorted list. In a for loop, I'm replacing the original string with the result of the function. In debugging when I step into my function the result displays the operated string correctly. After the first element is passed into the function the resulting first stringlist element is an empty string. The next pass into the function shows (before any code execution) show a result already of the previous returned value. After code execution on the second element when attempting to assign the new result I'm getting an AV (read of address) If it makes any difference the function result is AnsiString.

Support of the new SVN 1.9.x by Delphi Client Library? I struggled over the following small problem. We use for our internal workflow the Delphi client library provided as "open source"? http://svn.code.sf.net/p/radstudioverins/code/trunk/svn/ ) We use CollabNetSubversion-client-1.8.15-Win32.exe Now we tried to switch our environment to the newest SVN Client (1.9.x) CollabNetSubversion-client-1.9.3-1-Win32.exe But this leads to an AV raised from the SVN dll. Areas where the AV occurs Is there a plan to provide a maintained version of the SVN client code again to the public?

Hello Delphi Developers! I'M HIRING! Is anyone open to having a conversation today? My client is located in the metro Detroit area (relocation is paid for if you are out of state) and they are seeking a Sr. Technical Engineer professional. They specifically need this person to be familiar with Delphi and is open to learning new technologies! They are currently migrating Delphi to a .NET framework. Please let me know if this is something you would be open to discussing or have someone in mind that would be interested.

Houston we probable have a problem... I'm not 100% sure but close enough to be sure. It is about using of the TurboPack components simultaneously in the Berlin and Seattle. Part one - how to... 1. Install and register "Delphi 10.1 Berlin" without uninstall of "Delphi 10 Seattle"; 2. Use "Delphi 10.1 Berlin" - everything is ok; 3. Install the third party components from some folders - no problems; 4. Install something from GetIt - for example VirtualTree(TurboPack); 5. Try to build and after that to run a project from "Delphi 10.1 Berlin" - without problems; 6. Stop the "Delphi 10.1 Berlin" and try to do the same from "Delphi 10 Seattle". Upss... (for me - access violations and... problems); Where is the problem? I think that it is a cumulative. 1. The installation of the "Delphi 10.1 Berlin" added an information in the environment/System variables of the OS: - in the beginning of the values for "Variable=Pa

Originally shared by Jeroen Wiert Pluimers Since Delphi (XE8) does not adhere the `$(PROJECTNAME)` in a "Unit Output Directory" of `.\$(Platform)\$(Config)\$(PROJECTNAME)` - it makes the DCU files end up in `.\$(Platform)\$(Config)` What is a good strategy for a project-group containing multiple project for: 1. All the EXE ending up in the same directory, but depending on $(Platform) and $(Config) 2. The DCU files all ending up in different directories for each project, but also depending on $(Platform) and $(Config)

An email account that should only be known to myself and Embarcadero (and I suppose whoever they might share with) is suddenly getting viri laden emails from some folks doing some phishing,. Our email system (give everyone a custom email account so you can track this sort of thing and turn it off) seems to be a reasonable precursor for predicting news stories about this sort of thing. Adobe to comes to mind. hmmm. So far, the system has held true. Just saying, one might want to consider changing account passwords... I'm sticking up a post it note to remind me to get that done. Just a heads up. I'm not pointing any fingers. But something smells compromised, and I just hope to heck it's not on my side. Joe
