IOleObject
Object Linking & Embedding (OLE) is a proprietary technology developed by Microsoft that allows embedding and linking to documents and other objects. For developers, it brought OLE Control Extension (OCX), a way to develop and use custom user interface elements. On a technical level, an OLE object is any object that implements the IOleObject interface, possibly along with a wide range of other interfaces, depending on the object's needs. Overview OLE allows an editing application to export part of a document to another editing application and then import it with additional content. For example, a desktop publishing system might send some text to a word processor or a picture to a bitmap editor using OLE. The main benefit of OLE is to add different kinds of data to a document from different applications, like a text editor and an image editor. This creates a Compound File Binary Format document and a master file to which the document makes reference. Changes to data in the ma ...

Proprietary Format
A proprietary file format is a file format of a company, organization, or individual that contains data that is ordered and stored according to a particular encoding-scheme, designed by the company or organization to be secret, such that the decoding and interpretation of this stored data is easily accomplished only with particular software or hardware that the company itself has developed. The specification of the data encoding format is not released, or underlies non-disclosure agreements. A proprietary format can also be a file format whose encoding is in fact published, but is restricted through licences such that only the company itself or licensees may use it. In contrast, an open format is a file format that is published and free to be used by everybody. Proprietary formats are typically controlled by a company or organization for its own benefits, and the restriction of its use by others is ensured through patents or as trade secrets. It is thus intended to give the licen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Componentry
Component-based software engineering (CBSE), also called component-based development (CBD), is a branch of software engineering that emphasizes the separation of concerns with respect to the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software. Software engineering practitioners regard components as part of the starting platform for service-orientation. Components play this role, for example, in web services, and more recently, in service-oriented architectures (SOA), whereby a component is converted by the web service into a ''service'' and subsequently inherits further characteristics beyond that of an ordinary component. Components can produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Link Library
Dynamic-link library (DLL) is Microsoft's implementation of the shared library concept in the Microsoft Windows and OS/2 operating systems. These libraries usually have the file extension DLL, OCX (for libraries containing ActiveX controls), or DRV (for legacy system drivers). The file formats for DLLs are the same as for Windows EXE files – that is, Portable Executable (PE) for 32-bit and 64-bit Windows, and New Executable (NE) for 16-bit Windows. As with EXEs, DLLs can contain code, data, and resources, in any combination. Data files with the same file format as a DLL, but with different file extensions and possibly containing only resource sections, can be called ''resource DLLs''. Examples of such DLLs include ''icon libraries'', sometimes having the extension ICL, and font files, having the extensions FON and FOT. Background The first versions of Microsoft Windows ran programs together in a single address space. Every program was meant to co-operate by yielding the CPU ...

Visual Basic Extension
In computer programming, a Visual Basic Extension (commonly abbreviated VBX) or custom control, was the software component, component model used in Microsoft Visual Basic (classic), Visual Basic versions 1.0 to 3.0. It is still supported in the 16-bit version of version 4.0, but was made obsolete by OCXs. VBX has also been supported in the first, 16-bit version of Borland Delphi. The VBX specification was created so that developers could extend Visual Basic (classic), Visual Basic. Since at the time Visual Basic was an interpreted language with limited speed, VBXs, which were most often written in C or C++, provided the ability to create very powerful and efficient user interface sub-components which could be assembled into applications using Visual Basic as the glue. Visual Basic 4.0 added support for the newer Object_Linking_and_Embedding#OLE_custom_controls, OLE Controls or OCXs (which became ActiveX controls), implicitly deprecating VBX controls. OCXs are based on the Component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moniker
A nickname is a substitute for the proper name of a familiar person, place or thing. Commonly used to express affection, a form of endearment, and sometimes amusement, it can also be used to express defamation of character. As a concept, it is distinct from both pseudonym and stage name, and also from a title (for example, City of Fountains), although there may be overlap in these concepts. Etymology The compound word ''ekename'', literally meaning "additional name", was attested as early as 1303. This word was derived from the Old English phrase ''eac'' "also", related to ''eacian'' "to increase". By the 15th century, the misdivision of the syllables of the phrase "an ekename" led to its rephrasing as "a nekename". Though the spelling has changed, the pronunciation and meaning of the word have remained relatively stable ever since. Conventions in various languages English nicknames are generally represented in quotes between the bearer's first and last names (e.g., '' D ...

COM Structured Storage
COM Structured Storage (variously also known as ''COM structured storage'' or '' OLE structured storage'') is a technology developed by Microsoft as part of its Windows operating system for storing hierarchical data within a single file. Strictly speaking, the term ''structured storage'' refers to a set of COM interfaces that a conforming implementation must provide, and not to a specific implementation, nor to a specific file format (in fact, a structured storage implementation need not store its data in a file at all). In addition to providing a hierarchical structure for data, structured storage may also provide a limited form of transactional support for data access. Microsoft provides an implementation that supports transactions, as well as one that does not (called ''simple-mode'' storage, the latter implementation is limited in other ways as well, although it performs better). Structured storage is widely used in Microsoft Office applications, although newer releases (st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-place Activation
In computer science, an in-place algorithm is an algorithm which transforms input using no auxiliary data structure. However, a small amount of extra storage space is allowed for auxiliary variables. The input is usually overwritten by the output as the algorithm executes. An in-place algorithm updates its input sequence only through replacement or swapping of elements. An algorithm which is not in-place is sometimes called not-in-place or out-of-place. In-place can have slightly different meanings. In its strictest form, the algorithm can only have a constant amount of extra space, counting everything including function calls and pointers. However, this form is very limited as simply having an index to a length array requires bits. More broadly, in-place means that the algorithm does not use extra space for manipulating the input but may require a small though nonconstant extra space for its operation. Usually, this space is , though sometimes anything in is allowed. Note tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag-and-drop
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what is the command performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer to the object * Press, and hold down, the button on the mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing the button Dragging requires more physical effort than ...

OLE Automation
In Microsoft Windows applications programming, OLE Automation (later renamed to simply Automation) is an inter-process communication mechanism created by Microsoft. It is based on a subset of Component Object Model (COM) that was intended for use by scripting languages – originally Visual Basic – but now is used by several languages on Windows. All automation objects are required to implement the IDispatch interface. It provides an infrastructure whereby applications called ''automation controllers'' can access and manipulate (i.e. set properties of or call methods on) shared ''automation objects'' that are exported by other applications. It supersedes Dynamic Data Exchange (DDE), an older mechanism for applications to control one another. As with DDE, in OLE Automation the automation controller is the "client" and the application exporting the automation objects is the "server". Contrary to its name, automation objects do not necessarily use Microsoft OLE, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows XP
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, available for any devices running Windows NT 4.0, Windows 98, Windows 2000 and Windows Me that meet the new Windows XP system requirements. Development of Windows XP began in the late 1990s under the codename "Neptune", built on the Windows NT kernel explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of Windows not based on the Windows 95 kernel and MS-DOS. Windows XP removed supp ...
