Action Message Format ( AMF ) is a binary format used to serialize object graphs such as ActionScript objects and XML, or send messages between an Adobe Flash client and a remote service, usually a Flash Media Server or third party alternatives. The Actionscript 3 language provides classes for encoding and decoding from the AMF format.

86-460: The format is often used in conjunction with Adobe's RTMP to establish connections and control commands for the delivery of streaming media. In this case, the AMF data is encapsulated in a chunk which has a header which defines things such as the message length and type (whether it is a "ping", "command" or media data). AMF was introduced with Flash Player 6, and this version is referred to as AMF0. It

172-581: A componentized architecture built on the Component Object Model (COM) technology. It consists of several major components, each of which is contained in a separate dynamic-link library (DLL) and exposes a set of COM programming interfaces hosted by the Internet Explorer main executable, iexplore.exe : Internet Explorer does not include any native scripting functionality. Rather, MSHTML.dll exposes an API that permits

258-459: A " quirks mode " in which it deliberately mimics nonstandard behaviors of old versions of MSIE for HTML and CSS rendering on screen (Internet Explorer always uses standards mode for printing). It also provides its own dialect of ECMAScript called JScript . Internet Explorer was criticized by Tim Berners-Lee for its limited support for SVG, which is promoted by W3C . Internet Explorer has introduced an array of proprietary extensions to many of

344-474: A (0x03) followed by a set of key-value pairs and end with a (0x09) as value (preceded by 0x00 0x00 as empty key entry). Keys are encoded as strings with the (0x02) 'type-definition' byte being implied (not included in the message). Values can be of any type including other objects and whole object graphs can be serialized in this way. Both object keys and strings are preceded by two bytes denoting their length in number of bytes. This means that strings are preceded by

430-485: A broad range of web pages and provide certain features within the operating system, including Microsoft Update . During the height of the browser wars , Internet Explorer superseded Netscape only when it caught up technologically to support the progressive features of the time.

516-883: A browser plug-in or independently on supported devices. Originally created by FutureWave under the name FutureSplash Player , it was renamed to Macromedia Flash Player after Macromedia acquired FutureWave in 1996. After Adobe acquired Macromedia in 2005, it was developed and distributed by Adobe as Adobe Flash Player. It is currently developed and distributed by Zhongcheng for users in China, and by Harman International for enterprise users outside of China, in collaboration with Adobe. Flash Player ran on SWF files that can be created using Adobe Flash Professional , Adobe Flash Builder , or third-party tools such as FlashDevelop. Flash Player supports video and raster graphics ; vector graphics ; 3D graphics ; embedded audio; and an object-oriented scripting language called ActionScript , which

602-764: A custom version of the Chromium browser with the Adobe Flash Player "time bomb" removed. This browser can access only a small set of SARS online pages containing Flash-based forms required for filing financial reports. Although no longer available directly from Adobe, all versions of Adobe Flash Player Projector (also known as Adobe Flash Player Standalone) lack the "time bomb" present in the newer plug-in variants, and thus continue to be able to play all supported Flash file formats , including SWF files, without modification. The Internet Archive hosts some Flash content and makes it playable in modern browsers via

688-474: A feature of Microsoft Edge , enabling Edge to display web pages using Internet Explorer 11's Trident layout engine and other components.

5762-528: The normal means of launching Internet Explorer in Windows 11 and later versions of Windows 10 , but it is still possible for users to launch the browser from the Control Panel 's browser toolbar settings or via PowerShell . On June 15, 2022, Internet Explorer 11 support ended for the Windows 10 Semi-Annual Channel (SAC). Users on these versions of Windows 10 were redirected to Microsoft Edge starting on February 14, 2023, and visual references to

5848-468: The number of security vulnerabilities that had been discovered in the software, and its nature as a closed platform controlled by Adobe. Apple co-founder Steve Jobs was highly critical of Flash Player, having published an open letter criticising the platform and detailing Apple's reasoning for not supporting Flash on its iOS device family. Its usage further waned due to more modern web standards which replaced some of Flash's functionality, reducing

5934-424: The object properties can be sorted in a different order from the one in which they are placed in actionscript. For coloring/markup, refer to the legend below. The code above will work only for built-in classes like Object . To serialise and deserialise custom classes, the user needs to declare them using the registerClassAlias command or else an error will be thrown by the player. Although, strictly speaking, AMF

6020-452: The player have been available at some point for BeOS . In 2011, Flash Player had emerged as the de facto standard for online video publishing on the desktop, with adaptive bitrate video streaming, DRM , and fullscreen support. On mobile devices, however, after Apple refused to allow the Flash Player within iOS 's integrated web browser, Adobe changed its strategy, enabling Flash content to be delivered as native mobile applications using

6106-479: The plugin was discontinued, some users have figured how to modify and repack the China-specific variant to bring it more in line with the global variant. This includes removing the "Flash Helper Service" and removing the China only installation restriction, along with all other geo-restrictions and tracking code. A "time bomb," similar to the one found in later versions of the global variant, is also present in

6192-542: The prior ActionScript 2, the Adobe ActionScript 3 compiler is a non- optimizing compiler , and produces inefficient bytecode in the resulting SWF, when compared to toolkits such as CrossBridge . CrossBridge , a toolkit that targets C++ code to run within the Flash Player, uses the LLVM compiler to produce bytecode that runs up to 10 times faster than code the ActionScript 3 compiler produces, only because

6278-548: The protocol specifies significant changes that allow for a more compressed format. The data markers are as follows: The first 4 types are not followed by any data (Booleans have two types in AMF3). Additional markers used by Flash Player 10 (the format is still referred to as AMF3) are as follows: AMF3 aims for more compression and one of the ways it achieves this is by avoiding string duplication by saving them into an array against which all new string are checked. The byte following

6364-802: The software. Although bearing a name like NCSA Mosaic, Spyglass Mosaic had used the NCSA Mosaic source code sparingly. The first version, dubbed Microsoft Internet Explorer, was installed as part of the Internet Jumpstart Kit in the Microsoft Plus! pack for Windows 95 . The Internet Explorer team began with about six people in early development. Internet Explorer 1.5 was released several months later for Windows NT and added support for basic table rendering. By including it free of charge with their operating system , they did not have to pay royalties to Spyglass Inc, resulting in

6450-407: The standards, including HTML, CSS, and the DOM. This has resulted in several web pages that appear broken in standards-compliant web browsers and has introduced the need for a "quirks mode" to allow for rendering improper elements meant for Internet Explorer in these other browsers. Internet Explorer has introduced several extensions to the DOM that have been adopted by other browsers. These include

6536-415: The string marker is no longer denoting pure length but it is a complex byte where the least significant bit indicated whether the string is 'inline' (1) i.e. not in the array or 'reference' (0) in which case the index of the array is saved. The table includes keys as well as values. In older versions of Flash Player there existed one number type called 'Number' which was a 64-bit double precision encoding. In

6622-551: The unmodified China variant; this is also removed in most repacks. In theory, these repacks should provide users outside of China with the latest security updates to Flash Player, without having to deal with invasive advertisements or worry about privacy risks. One such project, "Clean Flash Installer," was served a DMCA takedown from Adobe in October 2021. Adobe has partnered with Harman to support enterprise Flash Player users until at least 2023. The Harman Flash player variant

6708-452: The web through emulators such as Ruffle , with varying degrees of compatibility and performance, although this is not endorsed by Adobe . Starting from Chrome 76, Flash is disabled by default without any prompts to activate Flash content. Users who wanted to play Flash content had to manually set a browser to prompt for Flash content, and then during each browser session, enable Flash plugin for every site individually. Microsoft Edge, which

6794-478: Was a version of Flash Player kept up to date with security updates, but none of the new features or bug fixes available in later versions. In August 2016, Adobe discontinued the ESR branch and instead focused solely on the standard release. Version 10 can be run under Windows 98/Me using KernelEx. HP offered Version 6 of the player for HP-UX , while Innotek GmbH offered versions 4 and 5 for OS/2 . Other versions of

6880-598: Was announced that Adobe would be bringing Flash to TV sets via Intel Media Processor CE 3100 before mid-2009. ARM Holdings later said it welcomes the move of Flash, because "it will transform mobile applications and it removes the claim that the desktop controls the Internet." However, as of May 2009, the expected ARM/Linux netbook devices had poor support for Web video and fragmented software base. Among other devices, LeapFrog Enterprises provides Flash Player with their Leapster Multimedia Learning System and extended

6966-475: Was made available for Windows Server 2012 and Windows Embedded 8 Standard , the only still supported edition of Windows 8 in April 2019. Microsoft Edge was officially unveiled on January 21, 2015 as "Project Spartan". On April 29, 2015, Microsoft announced that Microsoft Edge would replace Internet Explorer as the default browser in Windows 10. However, Internet Explorer remained the default web browser on

7052-1283: Was once the most widely used web browser, attaining a peak of 95% usage share by 2003. It has since fallen out of general use after retirement. This came after Microsoft used bundling to win the first browser war against Netscape , which was the dominant browser in the 1990s. Its usage share has since declined with the launches of Firefox (2004) and Google Chrome (2008) and with the growing popularity of mobile operating systems such as Android and iOS that do not support Internet Explorer. Microsoft Edge, IE's successor, first overtook Internet Explorer in terms of market share in November 2019. Versions of Internet Explorer for other operating systems have also been produced, including an Xbox 360 version called Internet Explorer for Xbox and for platforms Microsoft no longer supports: Internet Explorer for Mac and Internet Explorer for UNIX ( Solaris and HP-UX ), and an embedded OEM version called Pocket Internet Explorer, later rebranded Internet Explorer Mobile , made for Windows CE , Windows Phone , and, previously, based on Internet Explorer 7, for Windows Phone 7 . The browser has been scrutinized throughout its development for its use of third-party technology (such as

7138-436: Was started in the summer of 1994 by Thomas Reardon , who, according to former project lead Ben Slivka, used source code from Spyglass, Inc. Mosaic, which was an early commercial web browser with formal ties to the pioneering National Center for Supercomputing Applications (NCSA) Mosaic browser. In late 1994, Microsoft licensed Spyglass Mosaic for a quarterly fee plus a percentage of Microsoft's non-Windows revenues for

7224-481: Was supported until October 10, 2023 alongside the end of support for Windows Embedded Compact 2013 , while IE9 is supported until January 13, 2026 alongside the end of ESU support for Premium Assurance customers on Windows Server 2008 . Barring additional changes to the support policy, Internet Explorer 11 will be supported until January 13, 2032, concurrent with the end of support for Windows 10 IoT Enterprise LTSC 2021. Internet Explorer has been designed to view

7310-621: Was the final release, and Microsoft began the process of deprecating Internet Explorer. During this process, it will still be maintained as part of Microsoft's support policies. Since January 12, 2016, only the latest version of Internet Explorer available for each version of Windows has been supported. At the time, nearly half of Internet Explorer users were using an unsupported version. In February 2019, Microsoft Chief of Security Chris Jackson recommended that users stop using Internet Explorer as their default browser. Various websites have dropped support for Internet Explorer. On June 1, 2020,

7396-554: Was unchanged until the release of Flash Player 9 and ActionScript 3.0, when new data types and language features prompted an update, called AMF3. Flash Player 10 added vector and dictionary data types documented in a revised specification of January 2013. Adobe Systems published the AMF binary data protocol specification in December 2007 and announced that it will support the developer community to make this protocol available for every major server platform. The following amf-packet
