Now you can create a new Delphi 7 application (a standard Win32 program) and use the.NET objects as if they were COM objects. Here is the code from the NetImport example, shown in Figure 12.14.
Delphi is an (IDE) for of desktop, and software, developed. It is also an language. Delphi's compilers use their own dialect of and generate for, ( only), and ( only). Since 2016, there have been new releases of Delphi every six months, with new platforms being added approximately every second release.
Delphi 10.2 Tokyo. With the current version of Delphi, you also get access to licenses for older versions – Delphi XE4-10.1 Berlin, Delphi 7 and 2007-XE3, Delphi 6 and 2007-XE3, HTML5 Builder XE3 and RadPHP XE-XE2.
Delphi includes a code editor, a visual designer, an integrated debugger, a component, and support for third-party. The code editor features , Error Insight (real-time error-checking),. The visual forms designer has traditionally used (VCL) for native Windows development, but the (FMX) platform was later added for cross-platform development. Database support in Delphi is very strong. A Delphi project of a million lines to compile in a few seconds – one benchmark gave 170,000 lines per second. Delphi was originally developed by as a tool for Windows as the successor of. Delphi added full to the existing language, and since then the language has grown to support generics and, and native (COM) support.
In 2006, Borland’s developer tools section was transferred from Borland to a wholly owned subsidiary known as, which was sold to in 2008. In 2015, Embarcadero was purchased by, but the Embarcadero mark was retained for the developer tools division. Delphi and its counterpart, are interoperable.
They share many core components, notably the IDE, VCL, and much of the. In addition, they can be used jointly in a project. For example, CBuilder 6 and later can consume Delphi source code and C in one project, while packages compiled with CBuilder can be used from within Delphi. In 2007, the products were released jointly as, a shared host for Delphi and CBuilder, which can be purchased with either or both. Contents. Features Delphi supports (RAD).
Among the features supporting RAD are the and the visual designer. Delphi uses the -based programming language called introduced by Borland. It supports native.
Its visual designer has traditionally used (VCL) for RAD. To better support development for Microsoft Windows and interoperate with code developed with other software development tools, Delphi supports independent interfaces of (COM) with class implementations, and support for many third-party components.
Implementations can be delegated to fields or properties of classes. Message handlers are implemented by tagging a method of a class with the integer constant of the message to handle. Connectivity is extensively supported through the many VCL database-aware and database access components. Later versions have included upgraded and enhanced runtime library routines provided by the community group, established in 2003.
Characteristics Delphi is a, intended to be easy to use and originally based on the earlier Object Pascal language. Was originally developed as a general-purpose language 'suitable for expressing the fundamental constructs known at the time in a concise and logical way', and 'its implementation was to be efficient and competitive with existing FORTRAN compilers' but without low-level programming facilities or access to hardware. Turbo Pascal and its descendants, including Delphi, support access to hardware and low-level programming, with the facility to incorporate code written in and other languages.
Delphi's features only class- and interface-based. Metaclasses are first class objects. Objects are actually references to the objects (as in ), which Delphi implicitly de-references, so there is usually no need to manually allocate memory for pointers to objects or use similar techniques that some other languages need. There are dedicated reference-counted string types, and also null-terminated strings. Strings can be concatenated by using the '+' operator, rather than using functions.
Garena Mobile comes with the best features of GAS for PC, specially the games you can link to your account like League of Legends or FIFA Online 3. This app is a powerful tool not only for heavy players but also for sporadic gamers that particularly enjoy the social aspect of their games. Moreover, Garena Mobile offers players a game called Magic Spin so users can win in-app gifts for several games! It allows you to chat with your friends individually or in a group on your phone, and you can also manage your buddy list and search for them to quickly start a chat.
For dedicated string types Delphi handles memory management without programmer intervention. Since Borland Developer Studio 2006 there are functions to locate. Delphi includes an integrated IDE.
The Delphi products all ship with a (VCL), including most of its source code. Third-party components (sometimes with full ) and tools to enhance the IDE or for other Delphi related development tasks are available, some free of charge. The IDE includes a GUI for localization and translation of created programs that may be deployed to a translator; there are also third-party tools with more features for this purpose.
The VCL framework maintains a high level of source compatibility between versions, which simplifies updating existing source code to a newer Delphi version. Third-party libraries may need updates from the vendor but, if source code is supplied, recompilation with the newer version may be sufficient. The VCL was an early adopter of or; it uses a-'re-usable' component model, extensible by the developer.
With class helpers new functionality can be introduced to core RTL and VCL classes without changing the original source code of the RTL or VCL. The compiler is optimizing and single pass.
It can optionally compile to a single which does not require. Delphi can also generate standard DLLs, DLLs, automation servers and Windows services. The Delphi IDEs since Delphi 2005 increasingly support features such as method extraction and the possibility to create models from the source code or to modify the source through changes made in the model. Delphi has large communities on and the.
When Delphi was owned by Codegear, many of its employees actively participated. Backward compatibility Each new release of Delphi attempts to be as compatible as possible with earlier versions, so that already-developed software and libraries can be retained. Incompatibility necessarily arises as new functionality is added. Limitations Although each new release of Delphi attempts to keep as much backwards compatibility as possible to allow existing code reuse, new features, new libraries, and improvements sometimes make newer releases less than 100% backwards compatible. For example, the design of the standard class libraries (VCL/RTL) had become somewhat dated and restrictive; Embarcadero released in 2011 as part of Delphi XE2 a new compiler and cross-platform VCL replacement called FireMonkey, based on Direct3D and OpenGL, which runs on other platforms in addition to Windows, supporting their features, but is not fully backwards-compatible with VCL applications. FireMonkey applications do however allow easy sharing of non visual code with VCL applications, enabling a lot of code to be ported easily between the platforms.
Issues Some releases of Delphi have been reported to be unstable. Delphi XE7, in particular, was often reported to be slow and subject to severe. Code examples To show a message. Procedure TForm1. ShowSomethingOnCreate; begin Label1. Text:= 'Hello World!' ; end; History Delphi was originally one of many codenames of a pre-release development tool project at.
Borland developer suggested the Delphi codename in reference to the. One of the design goals of the product was to provide database connectivity to programmers as a key feature and a popular database package at the time was; hence, 'If you want to talk to the Oracle, go to Delphi'.
As development continued towards the first release, the Delphi codename gained popularity among the development team and beta testing group. However, the Borland marketing leadership preferred a functional product name over an iconic name and made preparations to release the product under the name 'Borland AppBuilder'. Shortly before the release of the Borland product, Novell AppBuilder was released, leaving Borland in need of a new product name. After much debate and many market research surveys, the Delphi codename became the Delphi product name. The chief architect behind Delphi was, who had developed. He was persuaded to move to in 1996.
On February 8, 2006 Borland announced that it was looking for a buyer for its IDE and database line of products, including Delphi, to concentrate on its line. On November 14, 2006 Borland transferred the development tools group to an independent subsidiary company named, instead of selling it. Borland subsequently sold CodeGear to in 2008. Embarcadero retained the CodeGear division created by Borland to identify its tool and database offerings, but identified its own database tools under the DatabaseGear name. In 2015, Embarcadero was purchased by, but the Embarcadero mark was retained for the developer tools division.
Versions. Inprise Delphi 4.0. Early Borland years (1995–2003) Borland Delphi Delphi (later known as Delphi 1) was released in 1995 for the 16-bit, and was an early example of what became known as (RAD) tools. Delphi evolved from Borland's 'Turbo Pascal for Windows', itself an evolution with Windows support from Borland's Turbo Pascal and Borland Pascal with Objects, very fast 16-bit native-code MS-DOS compilers with their own sophisticated (IDE) and toolkit for. Early Turbo Pascal (for MS-DOS) was written in a dialect of the; in later versions support for was added, and it was named. Delphi has always used Object Pascal, which continued to be developed, as its underlying.
Borland Delphi 2 Delphi 2, released in 1996, supported 32-bit Windows environments. Delphi 1 was bundled with it for creation of 16-bit Windows 3.1 applications. New components replacing Borland ReportSmith. Borland Delphi 3 Delphi 3, released in 1997, added new VCL components encapsulating the 4.71 version of Windows Common Controls (such as Rebar and Toolbar), TDataset architecture separated from BDE, DLL debugging, the code insight technology, component packages, component templates, DecisionCube and components for statistical graphing, ActiveForms, component packages and integration with through interfaces. Inprise Delphi 4 Inprise Delphi 4 was released in 1998.
IDE came with a completely overhauled editor and became dockable. VCL added support for ActionLists anchors and constraints. Additional improvements were method overloading, dynamic arrays, Windows 98 support, interoperability, high performance database drivers, development, and Microsoft support. It was the last version shipped with Delphi 1 for 16 bit programming. Borland Delphi 5 Borland Delphi 5 was released in 1999. Added concept of frames, parallel development, translation capabilities, enhanced integrated debugger, support, database support and Kylix In 2001 Borland released a Linux version of Delphi, named. To get a product out quickly and cheaply, they made the IDE depend on the libraries rather than Linux's native system libraries (glibc).
The expense of developing a native glibc version of Kylix, combined with the lack of Linux adoption among programmers at the time, made sales go soft, and Kylix was abandoned after version 3. This was the first attempt to add Linux support in the Delphi product family. Kylix used the new CLX cross-platform framework, instead of Delphi's VCL. Borland Delphi 6 Attempts to support both Linux and Windows for cross-platform development were made, and a cross-platform alternative to the known as CLX shipped in 2001 with the release of Delphi 6. This was the second product in Borland's series of Linux-compatible native developer tools, establishing code-compatible IDEs for both Linux (see Kylix above) and Windows (Delphi 6) using the shared CLX component framework for both.
Later efforts would include CLX in CBuilder 6 and add C code-compatibility to the RAD tools line. Delphi 6 included the same CLX version (CLX 1) as the first version of Kylix. CLX 1 had been created before Delphi 6; its feature set was based on VCL 5 and lacked some features added to the VCL 6 shipped with Delphi 6.
Borland Delphi 7 Delphi 7, released in August 2002, became the standard version used by more Delphi developers than any other single version. It is one of the most successful IDEs created by Borland because of its stability, speed and low hardware requirements, and remains in active use as of 2017. Delphi 7 added support for Windows XP Themes, and added more support for building Web applications. It was the last version of Delphi that did not require mandatory. Later Borland years (2003–2008) Borland Delphi 8 Delphi 8 (Borland Developer Studio 2.0), released December 2003, was a -only release that compiled Delphi Object Pascal code into.NET; the IDE was rewritten for this purpose. The IDE changed to a docked interface (called Galileo) similar to Microsoft's Visual Studio.NET.
Delphi 8 was highly criticized for its low quality and its inability to create native applications (Win32 API/x86 code). The inability to generate native applications is only applicable to this release; the capability would be restored in the next release. Borland Delphi 2005 The next version, Delphi 2005 (Delphi 9, also Borland Developer Studio 3.0), included the Win32 and.NET development in a single IDE, reiterating Borland's commitment to Win32 developers. Delphi 2005 includes design-time manipulation of live data from a database. It also includes an improved IDE and added a for.
In statement (like C#'s ) to the language. However, it was widely criticized for its bugs; both Delphi 8 and Delphi 2005 had stability problems when shipped, which were only partially resolved in service packs. The ability to compile native windows applications (.exe) was added back into Delphi 2005 after being removed in Delphi 8.
CLX support was dropped for new applications from this release onwards. Borland Delphi 2006 In late 2005 Delphi 2006 (Delphi 10, also Borland Developer Studio 4.0) was released combining development of C# and Delphi.NET, Delphi Win32 and C (Preview when it was shipped but stabilized in Update 1) into a single IDE.
It was much more stable than Delphi 8 or Delphi 2005 when shipped, and improved further with the release of two updates and several hotfixes. Turbo Delphi and Turbo Delphi for.NET. RAD Studio XE2 World Tour On September 1, 2011 Embarcadero released RAD Studio XE2 (code-named Pulsar,) which included Delphi XE2, Embarcadero Prism XE2 (Version 5.0 later upgraded to XE2.5 Version 5.1) which was rebranded from Delphi Prism and RadPHP XE2 (Version 4.0). Delphi XE2 natively supports Windows (except the starter edition), in addition to the long-supported 32-bit versions, with some backwards compatibility.
Applications for 64-bit platforms can be compiled, but not tested or run, on the 32-bit platform. The XE2 IDE cannot debug 64-bit programs on Windows 8 and above. Delphi XE2 is supplied with both the VCL, and an alternative library called that supports Windows, and the Apple, and portable devices. FireMonkey and VCL are not compatible; one or the other must be used, and older VCL applications cannot use Firemonkey unless user interfaces are recreated with FireMonkey. Third parties have published information on how to use Firemonkey forms in VCL software, to facilitate gradual migration, but even then VCL and Firemonkey controls cannot be used on the same form.
Embarcadero says that support 'is being considered for the roadmap', as is, and that they are 'committed to. Expect regular and frequent updates to FireMonkey'. Pre-2013 versions only supported iOS platform development with Xcode 4.2.1 and lower, OS X version 10.7 and lower, and iOS SDK 4.3 and earlier. Embarcadero Delphi XE3 On September 4, 2012 Embarcadero released RAD Studio XE3, which included Delphi XE3, CBuilder, Embarcadero Prism XE3 (Version 5.2) and HTML5 Builder XE3 (Version 5.0) which was upgraded and rebranded from RadPHP. Delphi XE3 natively supports both 32-bit and editions of Windows (including Windows 8), and provides support for with the Firemonkey 2/FM² framework.
Support was dropped with XE3 release initially (with intent to add support back in with a separate product – Mobile Studio), but applications can continue to be targeted to that platform by developing with Delphi XE2. Embarcadero Delphi XE4 On April 22, 2013 Embarcadero released RAD Studio XE4, which included Delphi XE4, and CBuilder. There has been no major upgrade for either Embarcadero Prism or HTML5 Builder thence. Delphi XE4 is the first release of the mobile platform, featuring cross-platform mobile application development for the Simulator and Devices. In this version Embarcadero introduces two new compilers for Delphi mobile applications, the Delphi Cross Compiler for the iOS Simulator and the Delphi Cross Compiler for the iOS Devices. These compilers significantly differ from the Win64 desktop compiler as they do not support, inline assembly of CPU instructions, and six older string types such as PChar.

The new mobile compilers advance the notion of eliminating pointers. The new compilers require an explicit style of marshalling data to and from external APIs and libraries. Delphi XE4 Run-Time Library (RTL) is optimized for 0-based, read-only (immutable) Unicode strings, that cannot be indexed for the purpose of changing their individual characters.
The RTL also adds status-bit based exception routines for ARM CPUs that do not generate exception interrupts. Embarcadero Delphi XE5 On September 12, 2013 Embarcadero released RAD Studio XE5, which includes Delphi XE5 and CBuilder. It adds support for Android (specifically: ARM v7 devices running Gingerbread (2.3.3–2.3.7), Ice Cream Sandwich (4.0.3–4.0.4) and Jelly Bean (4.1.x, 4.2.x, 4.3.x)) and iOS 7. Embarcadero Delphi XE6 On April 15, 2014 Embarcadero released RAD Studio XE6, which included Delphi XE6 and CBuilder.
It allows to create natively-compiled apps for all platforms for, desktop, mobile, and wearable devices like Google Glass, with a single C or Object Pascal (Delphi) codebase. RAD Studio XE6 adds support for Android 4.4 KitKat. It also became possible to create FireMonkey mobile apps for Android. Embarcadero Delphi XE7 On September 2, 2014 Embarcadero released RAD Studio XE7, which included Delphi XE7 and CBuilder. It enables Delphi/Object Pascal and C developers to extend existing Windows applications and build apps that connect desktop and mobile devices with gadgets, cloud services, and enterprise data and APIs. Also, it enables developers to extend Windows applications using and App Tethering, and create shared user interface code across multiple device form factors, etc.
Embarcadero Delphi XE8 On April 7, 2015 Embarcadero released RAD Studio XE8, which included Delphi XE8 and CBuilder. Embarcadero Delphi 10 Seattle On August 31, 2015 Embarcadero released RAD Studio 10 Seattle, which included Delphi and CBuilder. Embarcadero Delphi 10.1 Berlin On April 20, 2016 Embarcadero released RAD Studio 10.1 Berlin, which included Delphi and CBuilder, both generating native code for the 32- and 64-bit Windows platforms, OSX, iOS and Android (ARM, MIPS and X86 processors). Delphi 10.1 Berlin Update 2 introduced the ability to create Windows 10 Store applications from the Delphi IDE using Desktop Bridge. Embarcadero Delphi 10.2 Tokyo On March 22, 2017 Embarcadero released RAD Studio 10.2 Tokyo, adding 64-bit Linux support, limited to console and non-visual applications.
In addition this release features RTL and IDE improvements, multi-tenancy support in RAD server and improved database capabilities. Embarcadero Delphi 10.2 Tokyo (Community Edition) On July 18, 2018 Embarcadero released Community Edition for free download. You are not allowed to earn more than $5,000. Library source code and VCL/FMX components are more limited compared to Professional. Roadmaps Embarcadero publishes 'roadmaps' describing their plans. The most recent one was published in August 2018. Related software RAD Studio Embarcadero sells RAD Studio, a suite of development tools that consists of Delphi, Embarcadero Prism, and HTML5 Builder.
Like Delphi, there are different editions of RAD Studio: Professional edition, Enterprise edition, Ultimate edition and Architect edition. InterBase integrates natively to Delphi and CBuilder for client/server or embedded development and can be accessed by all major languages and platforms in the market with database connection protocols like ODBC, ADO, ADO.NET and even with Java by JDBC/ODBC Bridge or Java type 4 connectors. Tool for Java development based on Eclipse since version JBuilder 2007. RadPHP (formerly Delphi for PHP). Main article: RadPHP (now superseded by HTML5 Builder) was an for that provides true RAD functionality. It has a form designer similar to that of Delphi or, and an integrated debugger based on the web server.
It also includes a library ported to PHP. Unlike other IDEs it supports Web 2.0 features such as. Delphi for PHP was announced on March 20, 2007, renamed on October 2010 to RadPHP, and is based on Qadram Q studio. Embarcadero acquired Qadram in January 2011. Delphi Prism Delphi Prism (later known as Embarcadero Prism) derived from the (previously known as Chrome) from RemObjects.
It ran in the Microsoft Visual Studio IDE rather than RAD Studio. It was licensed and re-branded by Embarcadero to replace Delphi.NET when that product was discontinued.
Although RemObjects Oxygene was further developed and incorporated support for native Java, Android, iOS and OS X development, the version licensed by Embarcadero was limited to only supporting.NET. It was eventually discontinued by Embarcadero with the release of Delphi XE4, leaving the Delphi product line with no support for.NET development. The Oxygene product it was based on continues to be developed by RemObjects as part of their Elements product line.
Free Pascal and Lazarus is an open-source Pascal that supports most of Delphi's Object Pascal code. Free Pascal also has its own language extensions, multiple compiler language syntax modes, and supports 18+ operating systems and 9+ processor architectures. Is a cross-platform RAD IDE that uses the Free Pascal compiler. Lazarus and Free Pascal – free software independent of Embarcadero – are largely compatible with code written for Delphi.
