FMX.D2DCanvas incorrectly draws bitmap brushes. It seems there is some kind of caching procedure TForm1.FormPaint(Sender: TObject; Canvas: TCanvas; const ARect: TRectF); var Path: TPath; BR: TBrush;   B: TBitmap; begin   B:=TBitmap.CreateFromFile('any_picture');   Path:=TPath.Create(nil);   Path.AddRectangle(RectF(0, 0, 300, 200));   BR:=TBrush.Create(TBrushKind.Bitmap, 0);   BR.Bitmap.Bitmap.Assign(B);   Canvas.FillPath(Path.Data, 1, BR);   BR.Bitmap.Bitmap.Resize(100, 100);   Canvas.FillPath(Path.Data, 1, BR);   Path.Free; end; Original bitmap will be drawn instead of resized. https://quality.embarcadero.com/browse/RSP-9656?filter=-2 Few other bugs and issues  I've found over the last week: https://quality.embarcadero.com/browse/RSP-9636 https://quality.embarcadero.com/browse/RSP-9635 https://quality.embarcadero.com/browse/RSP-9634 https://quality.embarcadero.com/browse/RSP-9632 https://quality.embarcadero.com/browse/RSP-9631 https://quality.embarcadero.com/browse/RSP-963...

Would somebody with XE7 please let me know whether this problem still exists there? "Hints not produced when they should in 64 bit debug builds":  http://qc.embarcadero.com/wc/qcmain.aspx?d=128644 Basically boils down to hints not being generated in 64-bit debug builds while they are generated in 64-bit release builds. I found the problem in XE2 and checked in XE6 (it's still there), but don't have XE7 available ... TIA, Marjan

Can someone with assembler experience tell me what the pascal equivalent of the StdWndProc function is? function StdWndProc(Window: HWND; Message, WParam: Longint;   LParam: Longint): Longint; stdcall; assembler; asm         XOR     EAX,EAX         PUSH    EAX         PUSH    LParam         PUSH    WParam         PUSH    Message         MOV     EDX,ESP         MOV     EAX,[ECX].Longint[4]         CALL    [ECX].Pointer         ADD     ESP,12         POP     EAX end; I understand it's purpose is to route windows messages to their destination window but I'd like to understand how it does this.

I have a slightly complex question about live tiles (with TLiveTile.) Suppose I would like to create a live tile app that acts as an intermediate to several other applications - ie, you have five different EXEs installed, and you want a live tile for each. I thought of creating one 'generic' live tile application, and allowing it to read image and caption info from a config file plus info about the app this instance of the tile app is an intermediate for, and then running / registering it five times, once for each of the apps it acts as an intermediate for. Is this possible? My research so far shows a TLiveTile has an appid that is written to a compiled-in resource (?) which means you might need to rebuild the app each time. Whereas I want to write one, re-useable live tile app - that's key. There might be other issues too: does every computer it's deployed on need a developer certificate, or can the app and the service it uses be installed on any Windows 8+ computer wi...

Hi, I am having some issue with my Delphi code in android. I am trying to save some changes to the SQLite database from my app. I have created record object for my tables and have a generic datamanager for handling all database calls. The issue I am facing is if any exception is raised within the datamanager object then android hangs and doesn't even show me the error message. I have given below snippet of my datamanager code and also two sets of code one which works properly and the other which causes the issue.  The error is raised by the validate procedure, which validates the data integrity and raises an exception if there are any inconsistencies. Code snippet from the datamanager for saving the record to the database. function TData_Manager .Save_Record(const ARec: T): Boolean; begin   { start a new transaction }   _ConMgr.Start_Transaction;   try     { Validate changes before saving }     FClass_Map.Validate(ARec);     { Save changes to database including any detail items }  ...

FastMM: I'm a newbie using this. Sadly, I've never used it and the output is a little scary on how many problems it finds. I've been breaking down the code into functional test units for FastMM, but it's slow going. I'm starting to think I'm missing some tricks. With some Googling, I found the following HOWTO that one of our friends from WideOrbit made. The link appears to be dead, as video.codegear.com doesn't seem to respond. (See below for details). Anyone have a good link for this or others for tricks on reading the output from FastMM? I understand it's call-stacks, that's the easy part, but I feel like I must be missing something.

Ok, is it just me, or does the Castalia "With removal" refactoring not work?  I keep getting "'Eliminate With' Cancelled: could not resolve xxxxx"

FastMM4 and lines in the *.dpr I've got an (old) problem, in which the IDE will take the lines required out of the "uses" clause in the *.dpr. Something I'm sure we're all aware of, but is there a solution to keep it from doing it? Below is a image of my uses clause and highlighted are the lines that are removed whenever I add/remove a unit from the project.

Migrating to FireDAC from ADO - Stored Proc Param Type Found an interesting little deviation today.   In a MSSQL stored proc with an TinyInt parameter, the insert statement suddenly complained that it could not insert the param with NULL value (as per constraint). After a lot of tracing, I was certain that we passed a 0 and not a NULL - and the only plausible reason was that I could see, was that the code was setting the param value, before setting the param datatype - so I rearranged the assignments to ensure that value was the last thing to be set. That fixed the issue.  Go figure. Params is Array of Variant. // ADO, MSSQL for i := Low(Params) to High(Params) do begin   p := AStoredProc.Parameters.AddParameter;   p.Direction := pdInput;   p.Value := Params[i];   p.DataType := VariantTypeToFieldType(VarType(Params[i]));   if p.Value = null    then p.Attributes := [paNullable]   else if VarType(Params[i]) = varBoolean   then begin     p.DataType := ftInteger;     if Params[i]      then...

I am working in Delphi XE6. I have OS X 10.9.5 in my Mac and I want to communicate with an Windows Service and Driver which is compatible only in Windows. I am running Windows 7 on Parallel Windows, and I want to communicate directly from OS X with Windows Service the Device Driver.  Any suggestion? So far I have just a simple client-server socket connection and it works fine when I send some text from the client to the server. I read  that I can use this connection for my project, so Server would be the App and the Client the Windows Service. How can I do this? Even if I do this, how can I communicate from an OS X App to an Windows Service through the Virtual Machine? Any help is highly appreciated!

Q: FMX : How to use custom columns with data bound grids? I would like to use a grid with livebindings and custom columns. How to inherit and implement custom columns is quite easy and clear. But I do not see the way how to get these into the grid. There is a ColumnStyle property that can be used to choose between Standard, Check-, Progress- and ImageColumns but after looking into the source they seem to be hardcoded. There is no way how to register own column classes. Any ideas?

Q: How do I determine if a variable, which should have been assigned with a TMyOtherObj.create(), but wasn't? It appears that Assigned() does not do this; as evaluating a Here's a quick sample code (not intended to be compile-able), just an attempt to document the question.  procedure TMyObj.AFunc(var AReturn : TMyOtherObj) begin    if (Assigned(AReturn)) then       AReturn.DoSomeThing(); end; var    AObj : TMyObj;    AReturn : TMyOtherObj; begin    AObj := TMyObj.create();    try       //FORGOT THIS LINE       //AReturn := TMyOtherObj.create();       AObj.AFunc(AReturn);    finally       AObj.Free();     end.

Anyone here know whether you can switch repeating rows in Excel on the fly, with VBA? The idea is, the sheet contains multiple grids, each with its own set of header rows. But the headers may be different, one grid to another.  My suspicion is that separate sheets is the only real solution.

Do you remember which VCL vendor partners with TRichView.com? I remember in the 'customer area' of some of the VCL vendors' website offer discount for products of their partners, but I don't remember which of them offers discount for TRichView(which I'm investigating) and you know, checking them one by one is kinda of a hassle :)

After updating to XE6 recently, we're having issues with frequent, but random, instances of compiler error F2063 - Could not compile unit. However, there are no other errors at all, and a full build always solves the issue, so there's not an actual code issue. Simply recompiling usually lets it move on, though it usually fails on another unit. The units it fails on is completely arbitrary and there is no discernable pattern at all. This is especially an issue in our CI builder, as doing full rebuilds there significantly slows down the CI cycle. However all of us are plagued with the issue, so it's not a OS or installation thing. We've not had any such issues with our previous Delphi versions. Anyone else been experiencing this?

I do wish Embarcadero would get an integrated CRM (they can talk to us if they like) so that they don't have to keep sending me amnesty emails to upgrade to XE7 - when I already have subscriptions.

Am looking for a component set which supports crating a database on at least FB, MSSQL, and SQLite. Is there such a beast? Also, I need a solution which is viable on Delphi at least as far back as XE, and preferable on D2007.

constructor TCustomIniFile.Create(const FileName: string); begin   FFileName := FileName; end; Been looking for a memory problem for a couple days. On a lark, I ran PAL to help find stuff. It pointed out Create() methods that didn't call "inherited" in the constructor.  However, it found a couple in the XE2 source System.Inifiles.TCustomIniFile.Create() and  System.Win.Registry.TRegistry.Create() and the overloaded version and the fancy class constructor I was under the impression that one must pretty much always call inherited first, but then I saw this... http://www.delphibasics.co.uk/RTL.asp?Name=Inherited "It is called at the start of a constructor, and at the end of a desctructor. It is not mandatory, but recommended as good practice." Ctrl-Click on inherited Create() for an Object, sure seems to have code that should go first (in all cases?). So I guess I'm kind of confused on when inherited is NOT something you'd call each and every time and what ...

All components finally installed (Total of about 5 hours) over the last month or so.  Finally put some time into using XE7 Pro and so far I'm very impressed with the stability and speed.  I beat on it quite a bit today both with component tweaking and getting my fairly large project running in it from XE4 (400K lines of code excluding 3rd party) and not one crash or glitch.   I do have a glitch to solve in the middleware I'm using but so far so good!

Has anyone here used default Delphi JSON marshaling classes (XE4 - DBXJSONReflect) in production code? I have tested it briefly today, and to say it nicely, it is completely unsuitable for the task. I would start filing QC reports, but it seems that poor thingy has been designed completely wrong, and last thing I want is to spend time reporting something that will be marked "As designed". It serializes fields instead of published properties, like VCL serialization does, that means I have to include new RTTI for private and protected members, it also means that whole bunch of transient fields will be included, and fields in resulting JSON start with prefix F. For comparison, mORMot JSON serialization works as I expected, and I don't mind using it, but I would prefer having out of the box functionality in Delphi to be usable.

I thinking about to create a master vm (citrix) with delphi and all needed components installed on it. Then i wants to clone this vm for my two developers.

So i could update only the master vm with the newest delphi version and components and clone this for my developers. The sourcecode (local svn copies on the home directorys) are not touched on this process. Have someone done this before? Could that work? What problems might be occur? Any help would be great!

While browsing Dr Dobb's, I came across this article on underused switches for the VC++ toolchain. How I wish there were equivalents for Delphi. (It is one of those articles split into ten different pages, sorry, and the single-page print version is not well organised / readable.) One day, Delphi will give compiled output comparable in speed to VC++, with an amazing optimizer, vectorization, parallelization, modern instruction sets (and even better compilation for various different instruction sets and the choice of which to use made at runtime) etc, and I will be a very happy person.  Some of these are one reason I'm keen to see the entire toolchain on every platform move to LLVM, and I'm very hopeful for the future and that we'll see great performance improvements. If you feel this is important, please feel free to contact Embarcadero and let them know (they do listen.) I should note that one or two of these exist in some form already, either in the Delphi toolchain o...

I owned the last version (expired as of April 2014) of DevExpress Quantum Grid pack.   I missed the upgrade period, so instead of paying $399, I would have to pay $799.   I saw what they added, and it's not worth the $399 to me, say nothing about $799, so I'm upgrading manually.   I had found an article by Jeff Overcash, and I have followed that, but now I'm to the point of building the components in the order they need to be built in (not fully documented by Jeff).    Question, once I get it to work, is it OK to present the order they're built in (here if anyone is interested) or is that in violation of the licensing agreement (reading that is worse than building the component set)?  Or if someone already has the order they should be built, can you publish here?

IDE package loading customization tool?  In my Delphi 7 days I used to use a tool from LMD for selecting which design time packages to load by the IDE, it's very helpful for several cases, for example, use different versions of a specific component library for different projects. But unfortunately that tool is no longer available in the LMD website, any alternatives? Thanks.

Is this a delphi string bug ? declaring a type as short string (subtypes) cause it's variable to be non unicode : type   SmallString = String[20]; var   SmStr: SmallString;   Str: String; begin   Str := 'UnicodeString';   SmStr := Str; // SmStr is no longer Unicode !   SmStr := SmStr; end; here is the sequence of allocated bytes (variable Str):img1. https://lh5.googleusercontent.com/-4lTgu3CbG_Q/VETvaOtUVrI/AAAAAAAAAUE/Hj34jzJmv8g/s219-p/unicode.PNG and img2 for the sequence of allocated bytes (variable SmStr) https://lh4.googleusercontent.com/-uKcgkITdwBw/VETv79YasLI/AAAAAAAAAUM/SKVqHl1dpn8/s219-p/nounicode.PNG Tested using the latest delphi version (XE7).

Hi All A while back I lost my hard drive and source code I have managed to reserct alot of my code now. But it would be handy to find a few functions source code from one of y .exe programs...I can decompile to machine code e.g bx,ax  00497034    mov        word ptr [ebp-122],bx  0049703B    mov        eax,4A4730; gvar_004A4730:AnsiString  00497040    mov        ecx,dword ptr [ebp-5C]  00497043    mov        edx,dword ptr [ebp-60]  00497046    call      @UStrCat3  0049704B    mov        eax,4A472C; gvar_004A472C:AnsiString  00497050    mov        ecx,dword ptr [ebp-64]  00497053    mov        edx,dword ptr [ebp-68]  00497056    call      @UStrCat3 how to then understand that , i.e what was that equivalent pascal source code? any help greatly appreciated :) Brian

FMX and iMac 5K Retina? Can FMX deal well with this comparatively extreme resolution? VCL has the same challenges with the new 3K and 4K displays under Windows 8.1 using system font scaling.  Even in the IDE, we already run into design time issues, as the forms are mangled if designed at one resolution/font scaling, and then are opened on another PC at a different resolution/font scaling. I wonder, are there any plans to look at solutions to this issue in the near future? https://forums.embarcadero.com/thread.jspa?threadID=109415&tstart=0

Does any know whether Delphi can generate 64 bit binaries for the Mac? At the moment the binaries I make appear to be 32 bit which means I am unable to load 64bit compiled dylibs. I couldn't see any options in the ide and a google search has turned up nothing. I'm using XE6.

For anyone with DevX experience with their memory dataset...  I have a performance issue, and it's driving me crazy. My table has 6 columns, 5 of which are integers, and the sixth is a string. I filter on two of the integer columns, and and the raw dataset has 276 rows. Calling UpdateFilters takes about 100mS, which seems awfully long for such a simple table. The call is made 276 times, so I get a total of about 27 seconds, just filtering this table. (Although there are 276 rows now, there could be more, if the complete data environment required it. There just happen to be 276 rows in this instance.) I am considering whether to leave it unfiltered, and search for the record(s) which would satisfy the criteria, or b) perhaps copy the whole mess to an array of records, and implement a search... or c) convert to using TClientDatasets. I tried adding indexes, and it made no difference. Basically, everything I have tried so far is counterintuitive in its impact.

I'd like to start a beta testing group for a new feature in TeeChart components and get feedback. If anybody is interested just comment here and I'll add you to a Google+ private community.

How to write a Delphi IDE plugin that paints on the code editor - Part 2. The first article showed how to write a plugin that drew 'Hello world' on the top left of the code editor. This second part shows how to know what file is being drawn onscreen, what lines of code are visible (including handling code folding), etc, so that you can paint whatever you want for any line of code or portion of text in that line of code, in the text or gutter areas. It also covers how to be compatible with other plugins also hooking the same functions. http://parnassus.co/mysteries-ide-plugins-painting-code-editor-part-2/ http://parnassus.co/mysteries-ide-plugins-painting-code-editor-part-2

I've updated TurboPower "Visual Plan It" so it works in Delphi XE7. The one thing that still needs to be done is changing the database engine from BDE to something newer. Any volunteers?

Hello! I've watched some videos about REST/Datasnap client server with XE5. The examples I saw shows using of simple functions. I will need to return a table result. How do I build this? Should be a procedure?

I'm thinking out loud here. I am building a DLL which will provide reporting services to an application. The DLL will be written in XE5 or XE6, but the app it must serve (initially) is in D2007. All well and good, so far. Where it gets interesting is that the user will be presented with a wizard for selecting options on each report. The options page(s) will typically contain checkboxes, radio groups, and lists from which things are selected. I was thinking that it would be handy if the DLL could send to the app the specifications for building the pages(s). There would also be some code interlocking control behavior, and each page would have a routine which writes the selected info about options to a dataset which will be passed to the routine which generates the report.  The DLL can't present the form, because we are crossing versions, and moreover, some of the clientside apps are running on unsupported versions of Windows. (I know, I know...) The benefit I would achieve is tha...

I would like to cache some database information in my remote servers. A lot of data does not change very often. The servers pool their datamodules. 1. At each request the server gets, a generation counter could be read from the database (requiring a fetch). The counter value maintained by triggers in the database. If the counter did not change the cache is used otherwise the new value and the updated data is fetched. 2. I could use DB Events (Firebird). When the generation counter changes an event is sent to a thread in the server that immediately refreshes the cache. All requests then use the cache. Option 1 will require a database operation for each request but will never "fail", i.e. deliver old data. Option 2 will be more efficient but i worry that an event could be missed by some reason and what to do then? A periodic pull would perhaps work in some circumstances, but not all.

Best practice: Self-updating service? Have any of you written self-updating software? I am looking for a robust way for a service to restart itself after it has downloaded a new .exe version.

It seems there is a bug in 64-bit compiler, affected all versions from XE2 to XE7 (maybe earlier too) const   MaxKernelSize = 30; type   TKernelSize = 1..MaxKernelSize;   X = array[-MaxKernelSize..MaxKernelSize] of cardinal; procedure TForm1.Button1Click(Sender: TObject); var   K: X;   KSize: TKernelSize;   t: cardinal; begin  KSize:=10;  t:=K[-KSize]; end;

Embarcadero Component Store I'd like to make a suggestion. With the great news that certain components will be sponsored by Embarcadero and maintained by Roman Kassebaum maybe the time is right for this idea. Wouldn't it be wonderful if Embarcadero has it's own component store for Delphi / C++ Builder?  It would be much like the App Store for the iOS.  You could browse and read the reviews before buying directly within the IDE. Once purchased, the components are automatically installed onto your machine. If you set up a new machine you simply install Delphi and log into your Component Store Account, and all of your components are automatically installed. I see it as a win-win-win for everyone. It's good for Embarcadero as they would get a commission for every sale (15% to 30% seems reasonable). It's good for the app developers as they have all of the commercial gubbins and transactions taken care of. They also have wider access as people can discover their component...

Did you know? You can still use some of the good old Wordstar shortcuts in Delphi. Example: ^KB for mark block begin, ^KK for block end, ^KC for copy block ... You have to press Ctrl+K first, followed by a single key press of the next command.

I have an odd bug in XE2 when using interfaced objects with properties in generics - would anyone know if this is a known QC? Situation: in a generic class of T with an interface constraint (so T has to support IMyInterface), I'm using an instance of T. T has a property, Filename : string, which uses a GetFilename method. If I call InstanceOfT.Filename, I get an access violation just off 0x0 when it calls the property access method. (That's as much as my rudimentary assembly can tell me.)  If I use Supports to get the interface my T instance supports, then call Filename using the interface not the object, it works fine.  Usually. In another method, just calling Supports fails with the same access violation inside QueryInterface. My first thought was that the object itself was invalid - freed, perhaps. But it's not, it is valid, I checked exhaustively tracing through every construction and destruction of every instance (this one is created, and none are destroyed), plus insp...

Hello GUYS  (It's a bug of Tib Components with Tibevents?) I have a question, may be my mistake, then I ask you to help me. I have a number of triggers that trigger update events in firebird. If I change via IBExpert or via firedac components, events are generated and read properly by TIbevents. All events are properly registered. But when I try to use TIB components, events are not generated. What can I be doing wrong? It's a bug of Tib Components? Ps: All events are registered in the appropriate components of alert. Always commited. Tks.

Problems Starting Parallel Tasks in Plain For Loop I'm having problems getting ITasks to work in a plane old "for" loop. I'd like to create a series of task in a for loop and carry on executing without waiting for them all to complete (otherwise I'd use a Parallel for loop). It compiles but doesn't work as I would expect. Take a look at this short screencast: http://screencast.com/t/XoX3mIcjv How would I accomplish this?
