Microsoft XML Core Services (MSXML) are set of services that allow applications written in JScript, VBScript, and Microsoft development tools to build Windows-native XML-based applications. It supports XML 1.0, DOM, SAX, an XSLT 1.0 processor, XML schema support including XSD and XDR, as well as other XML-related technologies.
All MSXML products are similar in that they are exposed programmatically as OLE Automation (a subset of COM) components. Developers can program against MSXML components from C, C++ or from Active Scripting languages such as JScript and VBScript. Managed .NET Interop with MSXML COM components is not supported nor recommended. [1]
As with all COM components, an MSXML object is programmatically instantiated by CLSID or ProgID. Each version of MSXML exposes its own set of CLSID's and ProgIDs. For example, to create an MSXML 6.0 DOMDocument object, which exposes the IXmlDomDocument, [2] IXmlDomDocument2, [3] and IXmlDomDocument3 [4] COM interfaces, the ProgID "MSXML2.DOMDocument.6.0" must be used.
MSXML also supports version-independent ProgIDs. Version-independent ProgIDs do not have a version number associated with them. For example, "Microsoft.XMLHTTP". These ProgIDs were first introduced in MSXML 1.0, however are currently mapped to MSXML 3.0 objects and the msxml3.dll.
Different versions of MSXML support slightly different sets of functionality. For example, while MSXML 3.0 supports only XDR schemas, it does not support XSD schemas. MSXML 4.0, MSXML 5.0, and MSXML 6.0 support XSD schemas. However, MSXML 6.0 does not support XDR schemas. Support for XML Digital Signatures is provided only by MSXML 5.0. For new XML-related software development, Microsoft recommends [5] using MSXML 6.0 or its lightweight cousin, XmlLite, for native code-only projects. [6]
MSXML is a collection of distinct products, released and supported by Microsoft. The product versions can be enumerated as follows: [7]
Internet Explorer is a deprecated series of graphical web browsers developed by Microsoft that were used in the Windows line of operating systems. While IE has been discontinued on most Windows editions, it remains supported on certain editions of Windows, such as Windows 10 LTSB/LTSC. Starting in 1995, it was first released as part of the add-on package Plus! for Windows 95 that year. Later versions were available as free downloads or in-service packs and included in the original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows. Microsoft spent over US$100 million per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999. New feature development for the browser was discontinued in 2016 and ended support on June 15, 2022, in favor of its successor, Microsoft Edge.
VBScript is a deprecated Active Scripting language developed by Microsoft that is modeled on Visual Basic. It allows Microsoft Windows system administrators to generate powerful tools for managing computers without error handling and with subroutines and other advanced programming constructs. It can give the user complete control over many aspects of their computing environment.
Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users, and is available for any devices running Windows NT 4.0, Windows 98, Windows 2000, or Windows Me that meet the new Windows XP system requirements.
Windows 2000 is a major release of the Windows NT operating system developed by Microsoft and designed for businesses. It was the direct successor to Windows NT 4.0, and was released to manufacturing on December 15, 1999, and was officially released to retail on February 17, 2000 and September 26, 2000 for Windows 2000 Datacenter Server. It was Microsoft's business operating system until the introduction of Windows XP Professional in 2001.
The Windows API, informally WinAPI, is Microsoft's core set of application programming interfaces (APIs) available in the Microsoft Windows operating systems. The name Windows API collectively refers to several different platform implementations that are often referred to by their own names. Almost all Windows programs interact with the Windows API. On the Windows NT line of operating systems, a small number use the Native API.
XSD, a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document, to assure it adheres to the description of the element it is placed in.
JScript is Microsoft's legacy dialect of the ECMAScript standard that is used in Microsoft's Internet Explorer 11 and older.
Microsoft Windows XP Professional x64 Edition, released on April 25, 2005, is an edition of Windows XP for x86-64 personal computers. It is designed to use the expanded 64-bit memory address space provided by the x86-64 architecture.
A Browser Helper Object (BHO) is a DLL module designed as a plugin for the Microsoft Internet Explorer web browser to provide added functionality. BHOs were introduced in October 1997 with the release of version 4 of Internet Explorer. Most BHOs are loaded once by each new instance of Internet Explorer. However, in the case of Windows Explorer, a new instance is launched for each window.
Microsoft Office 2003 is an office suite developed and distributed by Microsoft for its Windows operating system. Office 2003 was released to manufacturing on August 19, 2003, and was later released to retail on October 21, 2003, exactly two years after the release of Windows XP. It was the successor to Office XP and the predecessor to Office 2007. The Mac OS X equivalent, Microsoft Office 2004 for Mac was released on May 11, 2004.
Windows Internet Explorer 7 (IE7) is a web browser for Windows. It was released by Microsoft on October 18, 2006, as the seventh version of Internet Explorer and the successor to Internet Explorer 6. Internet Explorer 7 is part of a long line of versions of Internet Explorer and was the first major update to the browser since 2001. It was the default browser in Windows Vista and Windows Server 2008, as well as Windows Embedded POSReady 2009, and can replace Internet Explorer 6 on Windows XP and Windows Server 2003, but unlike version 6, this version does not support Windows 2000, Windows ME, or earlier versions of Windows. It also does not support Windows 7, Windows Server 2008 R2 or later Windows Versions.
Microsoft Data Access Components is a framework of interrelated Microsoft technologies that allows programmers a uniform and comprehensive way of developing applications that can access almost any data store. Its components include: ActiveX Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC). There have been several deprecated components as well, such as the Jet Database Engine, MSDASQL, and Remote Data Services (RDS). Some components have also become obsolete, such as the former Data Access Objects API and Remote Data Objects.
Dependency Walker or depends.exe is a free program for Microsoft Windows used to list the imported and exported functions of a portable executable file. It also displays a recursive tree of all the dependencies of the executable file. Dependency Walker was included in Microsoft Visual Studio until Visual Studio 2005 and Windows XP SP2 support tools. The latest version v2.2.10011 is not available on dependencywalker.com website but is included in the Windows Driver Kit v10.
Microsoft Management Console (MMC) is a component of Microsoft Windows that provides system administrators and advanced users an interface for configuring and monitoring the system. It was first introduced in 1998 with the Option Pack for Windows NT 4.0 and later came pre-bundled with Windows 2000 and its successors.
Resource Kit is a term used by Microsoft for a set of software resources and documentation released for their software products, but which is not part of that product. Resource kits offer supplementary resources such as technical guidance, compatibility and troubleshooting information, management, support, maintenance and deployment guides and multipurpose useful administrative utilities, which are available separately.
Windows Internet Explorer 8 (IE8) is the eighth and, by now, discontinued version of the Internet Explorer web browser for Windows. It was released by Microsoft on March 19, 2009, as the successor to Internet Explorer 7. It was the default browser in Windows 7 and Windows Server 2008 R2.
Wireless Zero Configuration (WZC), also known as Wireless Auto Configuration, or WLAN AutoConfig, is a wireless connection management utility included with Microsoft Windows XP and later operating systems as a service that dynamically selects a wireless network to connect to based on a user's preferences and various default settings. This can be used instead of, or in the absence of, a wireless network utility from the manufacturer of a computer's wireless networking device. The drivers for the wireless adapter query the NDIS Object IDs and pass the available network names (SSIDs) to the service. The service then lists them in the user interface on the Wireless Networks tab in the connection's Properties or in the Wireless Network Connection dialog box accessible from the notification area. A checked (debug) build version of the WZC service can be used by developers to obtain additional diagnostic and tracing information logged by the service.
Component Object Model (COM) is a binary-interface standard for software components introduced by Microsoft in 1993. It is used to enable inter-process communication object creation in a large range of programming languages. COM is the basis for several other Microsoft technologies and frameworks, including OLE, OLE Automation, Browser Helper Object, ActiveX, COM+, DCOM, the Windows shell, DirectX, UMDF and Windows Runtime. The essence of COM is a language-neutral way of implementing objects that can be used in environments different from the one in which they were created, even across machine boundaries. For well-authored components, COM allows reuse of objects with no knowledge of their internal implementation, as it forces component implementers to provide well-defined interfaces that are separated from the implementation. The different allocation semantics of languages are accommodated by making objects responsible for their own creation and destruction through reference-counting. Type conversion casting between different interfaces of an object is achieved through the QueryInterface method. The preferred method of "inheritance" within COM is the creation of sub-objects to which method "calls" are delegated.
Internet Explorer is a series of graphical web browsers developed by Microsoft and included as part of the Microsoft Windows line of operating systems, starting in 1995.
Microsoft started development on the .NET Framework in the late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2001 the first beta versions of .NET Framework 1.0 were released. The first version of .NET Framework was released on 13 February 2002, bringing managed code to Windows NT 4.0, 98, 2000, ME and XP.
