  • Can Delphi 5 generate a .PDB file that VS can use?

    - by Vilx-
    We've got this large application written in Delphi 5, and development is ongoing to this day. There is research going on into migrating to newer versions, but so far there is no success, as some 3rd party components have not been updated in ages and do not work on later versions. In the meantime however people need to continue work on it. Now Delphi 5 IDE is no real treat. It's pretty bug-ridden and lacks a lot of features of contemporary IDEs which makes it difficult to use. Especially when it comes to debugging. So I was wondering - would it be possible to use Visual Studio in the process? As far as I know the .PDB file format is pretty old and is well documented. Could it be possible to make the Delphi compiler to somehow generate a .PDB files for it's compiled results? Then the program could be debugged with Visual Studio, possibly to a much greater extent than in the original IDE. Well, the absolute Holy Grail would be to move all development to VS, just keeping the compiler from Delphi, but I imagine that would be pretty impossible.

  • tfs integration with delphi 2010

    - by Robert McCabe
    We are currently upgrading from Delphi 7 to Delphi 2010. With Delphi 7 we use Source Connection to integrate Delphi 7 with TFS, but there does not look like there is going to be a Delphi 2010 version in time. Is there any other integration option out there?

  • What should I do or don't do to avoid Delphi "push dword" bug.

    - by Maksee
    I found that Delphi 5 generates invalid assembly code in specific cases. I can't understand in what cases in general. The example below produces access violation since a very strange optimization occurs. For a byte in a record or array Delphi generates push dword [...], pop ebx, mov .., bl that works correctly if there are data after this byte (we need at least three to push dword correctly), but fails if the data is inaccessible. I emulated the strict boundaries here with win32 Virtual* functions Specifically the error occurs when the last byte from the block accessed inside FeedBytesToClass procedure. And if I try to change something like using data array instead of object property of remove actionFlag variable, Delphi generates correct assembly instructions. const BlockSize = 4096; type TSomeClass = class private fBytes: PByteArray; public property Bytes: PByteArray read fBytes; constructor Create; destructor Destroy;override; end; constructor TSomeClass.Create; begin inherited Create; GetMem(fBytes, BlockSize); end; destructor TSomeClass.Destroy; begin FreeMem(fBytes); inherited; end; procedure FeedBytesToClass(SrcDataBytes: PByteArray; Count: integer); var j: integer; Ofs: integer; actionFlag: boolean; AClass: TSomeClass; begin AClass:=TSomeClass.Create; try actionFlag:=true; for j:=0 to Count-1 do begin Ofs:=j; if actionFlag then begin AClass.Bytes[Ofs]:=SrcDataBytes[j]; end; end; finally AClass.Free; end; end; procedure TForm31.Button1Click(Sender: TObject); var SrcDataBytes: PByteArray; begin SrcDataBytes:=VirtualAlloc(Nil, BlockSize, MEM_COMMIT, PAGE_READWRITE); try if VirtualLock(SrcDataBytes, BlockSize) then try FeedBytesToClass(SrcDataBytes, BlockSize); finally VirtualUnLock(SrcDataBytes, BlockSize); end; finally VirtualFree(SrcDataBytes, MEM_DECOMMIT, BlockSize); end; end; Initially the error occured when I used access to RGB data of bitmap bits, but the code there is too complex so I narrowed it to this fragment. So the question is what is here so specific that makes Delphi produce push,pop,mov optimization. I need to know this in order to avoid such side effects in general.

  • TThread.resume is deprecated in Delphi-2010 what should be used in place?

    - by Charles Faiga
    In my multithread application I use TThread.suspend and TThread.resume Since moving my application to Delphi 2010 I get the following warring message [DCC Warning] xxx.pas(277): W1000 Symbol ‘Resume’ is deprecated If Resume is deprecated what should be used in place? EDIT 1: I use the Resume command to start the thread - as it is Created with 'CreateSuspended' set to True and Suspend before I terminate the thread. EDIT 2: Here is a link the delphi 2010 manual

  • Does a simple delphi form app needs any libraries or dependencies to deploy?

    - by peterg
    I need to code a simple form application and I want to make it easy to deploy (without installing libraries or dependencies), I don't want to use visual studio cpp or csharp because clr apps compile with .net frameworks and I have no much experience with mfc and dialogs. So I was wondering which libraries does a simple delphi vcl forms app (those using TForm) use, because I've never had to install anything to run simple delphi apps.

  • Prism - loading modules causes activation error

    - by Noich
    I've created a small Prism application (using MEF) with the following parts: - Infrastructure project, that contains a global file of region names. - Main project, that has 2 buttons to load other modules. - ModulesInterfaces project, where I've defined an IDataAccess interface for my DataAccess module. - DataAccess project, where there are several files but one main DataAccess class that implements both IDataAccess and IModule. When the user click a button, I want to show him a list of employees, so I need the DataAccess module. My code is as follows: var namesView = new EmployeesListView(); var namesViewModel = new EmployeesListViewModel(employeeRepository); namesView.DataContext = namesViewModel; namesViewModel.EmployeeSelected += EmployeeSelected; LocateManager(); manager.Regions["ContentRegion"].Add(new NoEmployeeView(), "noEmployee"); manager.Regions["NavigationRegion"].Add(namesView); I get an exception in my code when I'm trying to get DataAccess as a service (via ServiceLocator). I'm not sure if that's the right way to go, but trying to get it from the ModuleCatalog (as a type IDataAccess returns an empty enumeration). I'd appreciate some directions. Thanks. The problematic code line: object instance = ServiceLocator.Current.GetInstance(typeof(DataAccess.DataAccess)); The exact exception: Activation error occured while trying to get instance of type DataAccess, key "" The inner exception is null, the stack trace: at Microsoft.Practices.Prism.MefExtensions.MefServiceLocatorAdapter.DoGetInstance(Type serviceType, String key) in c:\release\WorkingDir\PrismLibraryBuild\PrismLibrary\Desktop\Prism.MefExtensions\MefServiceLocatorAdapter.cs:line 76 at Microsoft.Practices.ServiceLocation.ServiceLocatorImplBase.GetInstance(Type serviceType, String key) Edit The same exception is thrown for: container = (CompositionContainer)ServiceLocator.Current.GetInstance(typeof(CompositionContainer));

  • Using Prism with Ninject

    - by stiank81
    Is anyone out there using the Prism framework with Ninject instead of Unity? I need some functionality Unity isn't supporting yet, and I've decided to switch the IoC container to Ninject. I'm struggling a bit with the replace though.. What I need to use from Prism is the EventAggregator and the RegionManager. I have seen this sample that actually does the replace, but this is written for an older version of Prism, and several of the classes seems to have changed etc. So I ended up all confused after looking doing some effort in trying to rewrite it. So - my question is basically: How can I replace Unity with Ninject? What are the necessary steps? Initially I assumed I could write a simple bootstrapper that creates and configures a Ninject container and uses this to resolve all other objects. I bind IEventAggregator to EventAggregator and IRegionManager to RegionManager, but it fails when creating the Shell and the RegionManager.CreateRegion is called. Problem is that it seems like I need to set a ServiceLocator somewhere as it fails on this line: IServiceLocator locator = ServiceLocator.Current; Any ideas and tips along the way?

  • ActiveX controls with old Delphi versions

    - by DamienD
    I'm testing a non visual ActiveX control based on a registered .ocx which I import into Delphi using the provided wizard. Then, I simply put the generated component on the main form of a new VCL application. Under old Delphi versions (D5 and D2007), when i launch the application, this raise an AV during the component initialization. with Delphi 2009 : no problem, the application starts smoothly. My questions are : Are there known enhancements of ActiveX management in recent Delphi versions which can explain this difference ? Can I suspect a bug in the ActiveX control, or can I consider the origin of the problem is from old Delphi versions ? I need to use this component (if tests OK) in D2007. Do you think that it is possible to correct the AV problem under D2007 by modifying the D2007 generated .tlb file (for example by trying to use the D2009 generated one) PS: the ActiveX control is not named, because my question is a general question about Delphi and ActiveX, not about a specific ActiveX control.

  • Is it possible to use Indy 10.5.8.0 with Delphi XE?

    - by jachguate
    The case I'm trying to update the INDY to the latest version for my Delphi XE (Update 1), so I downloaded the latest INDY10 file (Indy_4545.zip) from indy.fulgan.com/ZIP. The packages compiles successfully and I can now even see the new version 10.5.8.0 on the about box dialog, but after a IDE restart I got a message saying: No se encuentra el punto de entrada del procedimiento @Idhttp@TIdCustomHTTP@GetRequestHeaders$qqrv en la biblioteca de vínculos dinámicos IndyProtocols150.bpl. My free translation to English: Entry point not found for procedure @Idhttp@TIdCustomHTTP@GetRequestHeaders$qqrv not found on the dynamic link library IndyProtocols150.bpl. After a quick comparision of old and new IdHTTP.pas I found a lot of changes on the TIdCustomHttp class, including the rename of some methods GetResponseHeaders to GetResponse GetRequestHeaders to GetRequest SetRequestHeaders to SetRequest Along with changed public/published method firms in this and other and classes interfaces. After the update, I got a lot of packages failing to load, including dclcxPivotGridOLAPD15.bpl, which in turns depends on dclDataSnapServer150.bpl which encounters the missing method on the bpl. AFAIK I can't recompile the dclDataSnapServer150.bpl (and maybe other failing packages, I just stopped here). DataSnap and DevExpress support on the IDE is a must for my day to day so The questions Is there a safe pre-established path to update to the newest INDY for Delphi XE? If not, am I on the safe side by just parching the source code by creating the old public methods and call the new ones on the implementation part? am I missing something else or am I really stuck with INDY 10.5.7 until the next Delphi minor/major release?

  • Exchanging strings (PChar) between a Freepascal compiled DLL and a Delphi compiled EXE

    - by John Riche
    After a lot of experimentations, I found a way to exchange PChar from a FreePascal compiled DLL with a Delphi compiled EXE. I'm in charge of both the DLL and EXE source code but one MUST BE in FreePascal and the other one in Delphi. My solution involves the following methods in the DLL: function GetAString(): PChar; var aString: string; begin aString := 'My String'; result := StrAlloc(length(aString) + 1); StrPCopy(result, aString); end; procedure FreeString(aString: PChar); begin StrDispose(aString); end; And from the Delphi EXE, to call the GetAString method, I need to Call the GetAString method, save the PChar to an actual Delphi String and call the FreeString method. Is this the best way of exchanging a string from a FreePascal DLL with a Delphi EXE ? Can I avoid the call to FreeString from Delphi ? And finally, if that's the correct solution, how will it behave with Delphi 2010 and the WideString by default: do I need to force WidePChar in FreePascal too ?

  • Delphi Prism getting Unknown Identifier "DllImport" error

    - by Robo
    I'm trying to call Window's SendMessage method in Delphi Prism, I've declared the class as follow: type MyUtils = public static class private [DllImport("user32.dll", CharSet := CharSet.Auto)] method SendMessage(hWnd:IntPtr; Msg:UInt32; wParam:IntPtr; lParam:IntPtr):IntPtr; external; protected public end; When I tried to compile, I get the error Unknown identifier "DllImport" I used this as an example, http://stackoverflow.com/questions/2708520/how-to-call-function-createprocess-in-delphi-prism and the syntax looks the same. Is there a setting I need to enable, or do I have a syntax error?

  • How can I make Delphi packages (create a .bpl file)?

    - by Pharaoh
    I want to create *.bpl file but I am failing to do so. Specifically, I am trying to make JEDI plugins, but I have tried an empty pure Delphi package, too. If I create a new package in Delphi XE3, I get an empty unit - if I "make" this project called "Package1.bpl", I get a .dcu file in "debug/win32/", but no .bpl file. No error is reported by the compiler. An empty JEDI plugin (bpl-style) only gives a .dcu, too, while an empty dll-style JEDI plugin gives a .cdu and a .dll file in "debug/win32/". This is the first time I am tryimg to make a new package, so I am completely lost. What am I missing? Pharaoh

  • How Can I List a TDictionary in Alphabetical Order by Key in Delphi 2009?

    - by lkessler
    How can I use a TEnumerator to go through my TDictionary in sorted order by key? I've got something like this: var Dic: TDictionary<string, string>; begin Dic := TDictionary<string, string>.create; Dic.Add('Tired', 'I have been working on this too long'); Dic.Add('Early', 'It is too early in the morning to be working on this'); Dic.Add('HelpMe', 'I need some help'); Dic.Add('Dumb', 'Yes I know this example is dumb'); { The following is what I don't know how to do } for each string1 (ordered by string1) in Dic do some processing with the current Dic element Dic.Free; end; So I would like to process my dictionary in the order: Dumb, Early, HelpMe, Tired. Unfortunately the Delphi help is very minimal in describing how TEnumerator works and gives no examples that I can find. There is also very little written on the web about using Enumerators with Generics in Delphi.

  • How to automize multiple projects build process by including digital signature of exe in Delphi?

    - by user193655
    After building a project group of 2 projects with Delphi (2009) I digitally sign the 2 exes using InstallAware Code signing, an exe that shipped with Delphi 2009. How is it possible to automize the digital signature, so when I build I can also attach digital signature. For digital signing I use a pvk (private key) file and an spc (Sw publisher certificate) file. Subquestion: Moreover I created a project group because I have 2 exes, but they are almost the same, the only thing that changes is the Application icon and the application name (one is ProductOne.dpr, the other is ProductTwo.dpr). In practice I have 2 brands of the same product, I have a single build but activation keys details activate one or the other, anyway now I was asked to change the icon and the filename, and for this I need to build 2 projects, activation key is not enough anymore to distinguish between the 2. Anyway if there is a way to do this from a single project it would be better.

  • Does Delphi really handle dynamic classes better than static?

    - by John
    Hello, I was told more than once that Delphi handles dynamic classes better than static.Thereby using the following: type Tsomeclass=class(TObject) private procedure proc1; public someint:integer; procedure proc2; end; var someclass:TSomeclass; implementation ... initialization someclass:=TSomeclass.Create; finalization someclass.Free; rather than type Tsomeclass=class private class procedure proc1; public var someint:integer; class procedure proc2; end; 90% of the classes in the project I'm working on have and need only one instance.Do I really have to use the first way for using those classes? Is it better optimized,handled by Delphi? Sorry,I have no arguments to backup this hypothesis,but I want an expert's opinion. Thanks in advance!

  • How can I make a Prism webapp look like Firefox to a website? (user agent spoofing)

    - by Alex Aaron Goven
    I thought it would be cool to use Mozilla's Prism to create a webapp for min.us, but drag and drop is disallowed because the site doesn't see the program as Firefox, Chrome or Safari, those of which are apparently the only browsers allowed to do drag and drop for fear that something will be horribly broken. I'm pretty sure Prism runs on the same engine as Firefox, yet I wouldn't doubt it if Prism is running on an older version since it's kind of a forgotten beta. Anyways, like the title says, I want to be able to make Prism webapps appear look like Firefox to websites to unlock awesome features. Also, if it can only be done with Fluid, then I answers regarding that will be fine. I'm not sure what engine it's running though.

  • Delphi Path Variables

    - by user337340
    Hey Everyone, I've got what I'm hoping is a simple question. In the Delphi IDE, the path to the Delphi installation is specified as $(DELPHI). I am wondering if there is a way to create my own path indicators, such as $(MY_LIBRARY) or something similar. I thought $(DELPHI) was specified as an environment variable, but apparently not. Any ideas? Thanks all! ~DJ DJ Quimby

  • Has anyone used RemObjects' Hydra to mix a large Delphi project with new C# additions?

    - by robsoft
    (Hopefully this is deemed suitable for Programmers, not StackOverflow - I could imagine it getting closed at SO because there's no obvious 'right' answer.) We have a large Delphi 2007 VCL project that uses things like DBXpress, Report Builder, DevExpress and TMS components (both visual and non-visual) etc. For reasons I won't bore you with, the company would like to start adding new modules to the program using .Net (via C# in particular). Rewriting from scratch isn't an option and given the heavy use of Report Builder and various other bits of Delphi-specific 3rd party code, I suspect that using something like TurnSharp to regenerate a C# project wouldn't work well either. Ideally we want to keep our Win32 VCL Delphi code but add new modules (plug-ins, sections of contained functionality like wizards etc) via C#. So we're considering RemObjects' Hydra, and in the next few weeks will probably have a go at evaluating it on a smaller-but-representative project first. I wondered if anyone had experience of doing this kind of thing with Hydra...?

  • How to change TXSDateTime SOAP serialization in Delphi 7?

    - by LukLed
    I am trying to use Java based webservice and have soap request: <?xml version="1.0"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body xmlns:NS1="http://something/"> <NS1:getRequest id="1"> <sessionId xsi:type="xsd:string"></sessionId> <reportType xsi:type="NS1:reportType">ALL</reportType> <xsd:dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <xsd:dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> </NS1:getRequest> <parameters href="#1" /> </SOAP-ENV:Body> </SOAP-ENV:Envelope> It doesn't work, because webservice doesn't recognize dates as parameters. When I change <xsd:dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <xsd:dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> to <dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> everything works ok, but Delphi (without Delphi source code changes) doesn't allow to change generated XML, it has only some options. Is it possible to set conversion options, so TSXDateTime is converted to <dateFrom, not <xsd:dateFrom tag? Did you meet that problem?
