C encompasses static typing, strong typinglexically scopedimperativedeclarativefunctionalgenericobject-oriented class -basedand component-oriented programming disciplines. Microsoft introduced C along with. At the time, Microsoft had no open-source products. Four years later, ina free and open-source project called Mono began, professiojal a cross-platform compiler and runtime environment for the C programming language. A decade later, Microsoft released Visual Studio Code code editorRoslyn compilerand the unified.

NET platform software frameworkall microsoft project professional 2019 part number free which support C and are free, open-source, and cross-platform. Mono also joined Microsoft but was not merged into. As of July[update] the most recent stable version of the language is C NET 6. The Ecma standard lists these design goals for C : [16]. During the development of the. By the time the. NET runtime had been ported to C. In interviews and technical papers he has stated that flaws [23] in most major programming languages e.

James Goslingwho created the Java programming language inand Bill Joya co-founder of Sun Microsystemsthe originator of Java, called C an “imitation” of Java; Gosling further said that “[C is] sort of Java with reliability, productivity and security deleted.

Boring repetition that lacks innovation,” [26] “Hardly anybody will claim that Java or C are revolutionary programming languages that changed the way we write programs,” and “C borrowed a lot from Java – and vice versa. Now that C supports boxing and unboxing, we’ll have a very similar feature in Java.

Rpofessional the release of C 2. One of the first major departures came with the addition of generics to both languages, with vastly different implementations. C makes use of reification to provide “first-class” generic objects that can be used like any other class, with code generation performed at class-load time. The LINQ extensions and the functional imports help developers reduce the amount of boilerplate code that is included in common tasks like profsesional a database, parsing an xml file, or searching through a data structure, shifting the emphasis onto the actual program logic to help improve readability and maintainability.

C used to have a mascot called Andy named after Microsoft project professional 2019 part number free Hejlsberg. It was retired on January microsoft project professional 2019 part number free, Microsoft first used the name C in for a variant of the C language designed for incremental compilation.

The name “C sharp” was inspired by the musical notation whereby a sharp symbol indicates that the written note should be made a semitone higher in pitch. Due to technical limitations of display standard fonts, browsers, etc.

The “sharp” suffix has been used by a number of other. NET languages that are variants of existing languages, including J a. NET language also designed by Microsoft вот ссылка is derived from Java 1.

NET was перейти на страницу Eiffel[42] a name retired since the full Eiffel language is now supported. The suffix has also been used for librariessuch as Gtk a. However, the language specification does not state the code generation requirements of the compiler: that is, it does not state that a C compiler must target a Common Language Runtime, or generate Common Intermediate Language CILor generate any other specific format.

C supports strongly, implicitly typed variable declarations with the keyword varand implicitly typed arrays with the keyword new[] followed by a microsoft project professional 2019 part number free initializer. C supports a strict Boolean data typebool. Statements that take conditions, such as while and ifrequire an expression of a type that implements the true operator, such as the Boolean type.

The only implicit conversions by default are those that are considered safe, such as widening of integers. This is enforced at compile-time, during JITand, in some numger, at runtime. No implicit conversions occur between Booleans and integers, nor between enumeration members and integers except for literal 0, which can be implicitly converted to any enumerated type. Enumeration members are placed in their own scope.

The C language does not allow for global variables or functions. All methods and members must be declared within classes. Static members of public classes can substitute for global variables and functions. Metaprogramming can be achieved in several ways:. A method in C is a member of a microsoft project professional 2019 part number free that can be invoked as a function microsoft project professional 2019 part number free sequence of instructionsrather than the mere value-holding capability of a class было microsoft office 2010 activation command prompt free download СУПЕР. Certain specific kinds of methods, such as those that simply get or set a class property by return value or assignment, do not 2109 a full rpofessional, but in the general case, the definition of a class includes the full signature declaration of its methods.

Extension methods in C allow programmers to use static methods as if they were methods from a class’s profeszional table, allowing programmers to add methods to an orofessional that they feel should exist on that object and its derivatives.

The type dynamic allows for run-time method binding, allowing for JavaScript-like method calls and run-time object composition. C has support for strongly-typed function pointers via the keyword delegate. Synchronized ]and has support for par locks via the keyword lock. C supports classes with properties. The properties can be simple accessor functions with a backing field, or implement getter and setter functions.

Since C 3. Namespaces can be imported with the “using” syntax. In Cmemory address pointers can only be used within blocks specifically marked as unsafe[69] and programs with unsafe code need appropriate permissions to run. Most object access is done through safe object references, which always either point to a “live” object or have the well-defined null value; it is impossible to obtain a reference to a “dead” nuumber one that has been garbage collectedor to a random block of memory.

An unsafe pointer can point to an instance of an ‘unmanaged’ value type that does not contain any references to garbage-collected objects, array, string, or a block of stack-allocated memory.

Code that is not marked as unsafe can still store and manipulate pointers through the System. IntPtr type, but it cannot dereference them.

Managed memory cannot be explicitly freed; instead, it is automatically garbage collected. Garbage collection addresses the problem of memory leaks by freeing the programmer of responsibility for releasing memory that is no longer needed in most cases.

Code that retains references to objects longer than is required can still experience higher memory usage than necessary, however once the final reference to an object is released the memory is available for garbage collection.

A range of standard exceptions are available to programmers. Methods in standard libraries regularly microsoft project professional 2019 part number free system exceptions in some circumstances and the range of exceptions thrown is normally documented. Custom exception classes can be defined for classes allowing specific handling to be put in place for particular circumstances as needed. Checked exceptions are not present in C in contrast to Java. This has been a conscious decision based on the issues of scalability and versionability.

This was a design decision by the language’s lead architect to avoid complications and to simplify architectural requirements throughout CLI.

When implementing multiple interfaces that contain a method with the same name and taking parameters of the same type in the same order i. However, unlike Java, C supports operator overloading.

C has the ability to utilize LINQ through the. NET Framework. Using LINQ in C brings advantages like Intellisense support, strong filtering capabilities, type safety with compile error checking ability, and consistency for querying data over a promect of sources. Though primarily an imperative language, C 2.

C has a unified type system. A unified type system implies that all types, including primitives such as integers, are subclasses of the System.

Object class. For example, every type inherits a ToString method. CTS separates data types into two categories: [79]. Instances of value types neither have referential identity nor referential comparison semantics.

Equality and inequality comparisons for value types compare the actual data values within the instances, unless the corresponding operators are overloaded. Value types are derived from System. ValueTypealways have a default value, and can always be created and по этому сообщению. Some other limitations on value types are that they cannot derive from each other but can implement interfaces and cannot have an numbrr default parameterless constructor.

Examples of value types are all primitive types, such as int a signed bit integerprodessional a bit IEEE floating-point numberchar a bit Unicode code unitand System. DateTime identifies a specific point in time with nanosecond precision.

Other examples are enum enumerations and struct user defined lart. Microsoft project professional 2019 part number free contrast, reference types microsodt the notion of referential identity, meaning that each instance of a reference type is inherently distinct from every other instance, even if the data within both instances is the same.

This is reflected in default equality and inequality comparisons for reference types, which test for referential rather than structural equality, unless the corresponding operators are overloaded such as the case for System. Some operations are not always possible, such as creating an instance of a reference type, copying an microsoft project professional 2019 part number free instance, or performing a value comparison on two existing instances.

Though specific reference types can provide such services by exposing a public constructor or implementing a patr interface such as ICloneable or IComparable. Examples of reference types are object the ultimate base class for all other C продолжение здесьSystem. String a string of Unicode charactersand System. Array a microsoft project professional 2019 part number free class for all C arrays. Boxing is the operation of converting a value-type object into a value of proect microsoft project professional 2019 part number free reference type.

Unboxing is the operation of converting a value of a reference type previously boxed into a value of a value type. A boxed object of type T can only be unboxed to a T or a nullable T. The C specification details a minimum set of types and class libraries that the compiler expects to have available. In microsoft project professional 2019 part number free to the standard CLI specifications, there are many commercial and community class libraries that build on top of the.

NET framework libraries to provide additional functionality.

Microsoft Access is a file server -based database. Unlike client—server relational database management systems RDBMS , Microsoft Access does not implement database triggers , stored procedures , or transaction logging. Access includes table-level triggers and stored procedures built into the ACE data engine.

Thus a Client-server database system is not a requirement for using stored procedures or table triggers with Access Tables, queries, forms, reports and macros can now be developed specifically for web based applications in Access Integration with Microsoft SharePoint is also highly improved. The edition of Microsoft Access introduced a mostly flat design and the ability to install apps from the Office Store, but it did not introduce new features.

The theme was partially updated again for , but no dark theme was created for Access. NET web forms can query a Microsoft Access database, retrieve records and display them on the browser. SharePoint Server via Access Services allows for Access databases to be published to SharePoint, thus enabling multiple users to interact with the database application from any standards-compliant Web browser. Access Web databases published to SharePoint Server can use standard objects such as tables, queries, forms, macros, and reports.

Access Services stores those objects in SharePoint. Access offers the ability to publish Access web solutions on SharePoint The macro language is enhanced to support more sophisticated programming logic and database level automation. Microsoft Access can also import or link directly to data stored in other applications and databases.

Microsoft offers free runtime versions of Microsoft Access which allow users to run an Access desktop application without needing to purchase or install a retail version of Microsoft Access. This actually allows Access developers to create databases that can be freely distributed to an unlimited number of end-users.

These runtime versions of Access and later can be downloaded for free from Microsoft. The runtime version allows users to view, edit and delete data, along with running queries, forms, reports, macros and VBA module code.

The runtime version does not allow users to change the design of Microsoft Access tables, queries, forms, reports, macros or module code. The runtime versions are similar to their corresponding full version of Access and usually compatible with earlier versions; for example Access Runtime allows a user to run an Access application made with the version as well as through Due to deprecated features in Access , its runtime version is also unable to support those older features.

Access stores all database tables, queries, forms, reports, macros, and modules in the Access Jet database as a single file. For query development, Access offers a “Query Designer”, a graphical user interface that allows users to build queries without knowledge of structured query language. In the Query Designer, users can “show” the datasources of the query which can be tables or queries and select the fields they want returned by clicking and dragging them into the grid.

One can set up joins by clicking and dragging fields in tables to fields in other tables. Access allows users to view and manipulate the SQL code if desired. Any Access table, including linked tables from different data sources, can be used in a query. Access also supports the creation of “pass-through queries”.

This enables users to interact with data stored outside the Access program without using linked tables or Jet. When developing reports in “Design View” additions or changes to controls cause any linked queries to execute in the background and the designer is forced to wait for records to be returned before being able to make another change.

This feature cannot be turned off. Non-programmers can use the macro feature to automate simple tasks through a series of drop-down selections. Macros allow users to easily chain commands together such as running queries, importing or exporting data, opening and closing forms, previewing and printing reports, etc.

Macros support basic logic IF-conditions and the ability to call other macros. Macros can also contain sub-macros which are similar to subroutines. In Access , enhanced macros included error-handling and support for temporary variables. Access also introduced embedded macros that are essentially properties of an object’s event.

This eliminated the need to store macros as individual objects. However, macros were limited in their functionality by a lack of programming loops and advanced coding logic until Access With significant further enhancements introduced in Access , the capabilities of macros became fully comparable to VBA.

They made feature rich web-based application deployments practical, via a greatly enhanced Microsoft SharePoint interface and tools, as well as on traditional Windows desktops. It is similar to Visual Basic 6.

To create a richer, more efficient and maintainable finished product with good error handling, most professional Access applications are developed using the VBA programming language rather than macros, except where web deployment is a business requirement. In the database container or navigation pane in Access and later versions, the system automatically categorizes each object by type e.

Many Access developers use the Leszynski naming convention , though this is not universal; it is a programming convention, not a DBMS-enforced rule. Developers deploy Microsoft Access most often for individual and workgroup projects the Access 97 speed characterization was done for 32 users.

Databases under 1 GB in size which can now fit entirely in RAM and simultaneous users are well within the capabilities of Microsoft Access. Disk-intensive work such as complex searching and querying take the most time. As data from a Microsoft Access database can be cached in RAM, processing speed may substantially improve when there is only a single user or if the data is not changing. In the past, the effect of packet latency on the record-locking system caused Access databases to run slowly on a virtual private network VPN or a wide area network WAN against a Jet database.

As of , [update] broadband connections have mitigated this issue. Performance can also be enhanced if a continuous connection is maintained to the back-end database throughout the session rather than opening and closing it for each table access. In July , Microsoft acknowledged an intermittent query performance problem with all versions of Access and Windows 7 and Windows Server R2 due to the nature of resource management being vastly different in newer operating systems.

In earlier versions of Microsoft Access, the ability to distribute applications required the purchase of the Developer Toolkit; in Access , and Access the “Runtime Only” version is offered as a free download, [44] making the distribution of royalty-free applications possible on Windows XP, Vista, 7 and Windows 8. Microsoft Access applications can adopt a split-database architecture. The single database can be divided into a separate “back-end” file that contains the data tables shared on a file server and a “front-end” containing the application’s objects such as queries, forms, reports, macros, and modules.

The “front-end” Access application is distributed to each user’s desktop and linked to the shared database. Using this approach, each user has a copy of Microsoft Access or the runtime version installed on their machine along with their application database. This reduces network traffic since the application is not retrieved for each use. The “front-end” database can still contain local tables for storing a user’s settings or temporary data. This split-database design also allows development of the application independent of the data.

One disadvantage is that users may make various changes to their own local copy of the application and this makes it hard to manage version control. When a new version is ready, the front-end database is replaced without impacting the data database. Microsoft Access has two built-in utilities, Database Splitter [46] and Linked Table Manager, to facilitate this architecture.

Linked tables in Access use absolute paths rather than relative paths, so the development environment either has to have the same path as the production environment or a “dynamic-linker” routine can be written in VBA. For very large Access databases, this may have performance issues and a SQL backend should be considered in these circumstances.

To scale Access applications to enterprise or web solutions, one possible technique involves migrating to Microsoft SQL Server or equivalent server database. A client—server design significantly reduces maintenance and increases security, availability, stability, and transaction logging. This feature was removed from Access A variety of upgrading options are available.

The corresponding SQL Server data type is binary, with only two states, permissible values, zero and 1. Regardless, SQL Server is still the easiest migration. Retrieving data from linked tables is optimized to just the records needed, but this scenario may operate less efficiently than what would otherwise be optimal for SQL Server. For example, in instances where multi-table joins still require copying the whole table across the network.

The views and stored procedures can significantly reduce the network traffic for multi-table joins. Finally, some Access databases are completely replaced by another technology such as ASP. NET or Java once the data is converted. Further, Access application procedures, whether VBA and macros, are written at a relatively higher level versus the currently available alternatives that are both robust and comprehensive.

Note that the Access macro language, allowing an even higher level of abstraction than VBA, was significantly enhanced in Access and again in Access In many cases, developers build direct web-to-data interfaces using ASP.

NET, while keeping major business automation processes, administrative and reporting functions that don’t need to be distributed to everyone in Access for information workers to maintain.

Microsoft Access applications can be made secure by various methods, the most basic being password access control; this is a relatively weak form of protection.

A higher level of protection is the use of workgroup security requiring a user name and password. Users and groups can be specified along with their rights at the object type or individual object level.

This can be used to specify people with read-only or data entry rights but may be challenging to specify. A separate workgroup security file contains the settings which can be used to manage multiple databases.

Databases can also be encrypted. MDE file. Some tools are available for unlocking and ” decompiling “, although certain elements including original VBA comments and formatting are normally irretrievable. Microsoft Access saves information under the following file formats :. There are no Access versions between 2. From Wikipedia, the free encyclopedia.

New features include Windows Aero , updated versions of the standard games e.

Despite this, Windows Vista was critically panned for its poor performance on older hardware and its at-the-time high system requirements. Windows 7 followed in nearly three years after its launch, and despite it technically having higher system requirements, [3] [4] reviewers noted that it ran better than Windows Vista. Windows 8 , which was released in , introduced many controversial changes, such as the replacement of the Start menu with the Start Screen, the removal of the Aero interface in favor of a flat, colored interface as well as the introduction of “Metro” apps later renamed to Universal Windows Platform apps , and the Charms Bar user interface element, all of which received considerable criticism from reviewers.

The following version of Windows, Windows 10 , which was released in , reintroduced the Start menu and added the ability to run Universal Windows Platform apps in a window instead of always in full screen. Windows 10 was generally well-received, with many reviewers stating that Windows 10 is what Windows 8 should have been.

The latest version of Windows, Windows 11 , was released on October 5, Windows 11 incorporates a redesigned user interface, including a new Start menu, a visual style featuring rounded corners, and a new layout for the Microsoft Store, [13] and also included Microsoft Edge by default.

The first independent version of Microsoft Windows, version 1. The project was briefly codenamed “Interface Manager” before the windowing system was implemented—contrary to popular belief that it was the original name for Windows and Rowland Hanson , the head of marketing at Microsoft, convinced the company that the name Windows would be more appealing to customers.

Windows 1. The first version of Microsoft Windows included a simple graphics painting program called Windows Paint ; Windows Write , a simple word processor ; an appointment calendar; a card-filer; a notepad ; a clock; a control panel ; a computer terminal ; Clipboard ; and RAM driver. Microsoft had worked with Apple Computer to develop applications for Apple’s new Macintosh computer, which featured a graphical user interface. As part of the related business negotiations, Microsoft had licensed certain aspects of the Macintosh user interface from Apple; in later litigation, a district court summarized these aspects as “screen displays”.

In the development of Windows 1. For example, windows were only displayed “tiled” on the screen; that is, they could not overlap or overlie one another. On December 31, , Microsoft declared Windows 1. Microsoft Windows version 2. Much of the popularity for Windows 2. Microsoft Windows received a major boost around this time when Aldus PageMaker appeared in a Windows version, having previously run only on Macintosh.

Some computer historians [ who? Like prior versions of Windows, version 2. In such a configuration, it could run under another multitasker like DESQview , which used the protected mode.

It was also the first version to support the High Memory Area when running on an Intel compatible processor. Version 2. In Apple Computer, Inc. Microsoft Corp.

Judge William Schwarzer dropped all but 10 of Apple’s claims of copyright infringement, and ruled that most of the remaining 10 were over uncopyrightable ideas. On December 31, , Microsoft declared Windows 2. Windows 3.

A few months after introduction, Windows 3. A “multimedia” version, Windows 3. This version was the precursor to the multimedia features available in Windows 3. The features listed above and growing market support from application software developers made Windows 3. Support was discontinued on December 31, Its API was incompatible with Windows.

Version 1. They cooperated with each other in developing their PC operating systems, and had access to each other’s code. After an interim 1. Microsoft would later imitate much of it in Windows Still, much of the system had bit code internally which required, among other things, device drivers to be bit code as well. It also removed Real Mode, and only ran on an or better processor. Later Microsoft also released Windows 3. In and , Microsoft released Windows for Workgroups WfW , which was available both as an add-on for existing Windows 3.

Windows for Workgroups included improved network drivers and protocol stacks, and support for peer-to-peer networking. There were two versions of Windows for Workgroups, WfW 3. Unlike prior versions, Windows for Workgroups 3. All these versions continued version 3. Even though the 3. The Windows API became the de facto standard for consumer software. On December 31, , Microsoft declared Windows 3. Meanwhile, Microsoft continued to develop Windows NT. This successor was codenamed Cairo.

In hindsight, Cairo was a much more difficult project than Microsoft had anticipated and, as a result, NT and Chicago would not be unified until Windows XP —albeit Windows , oriented to business, had already unified most of the system’s bolts and gears, it was XP that was sold to home consumers like Windows 95 and came to be viewed as the final unified OS.

Driver support was lacking due to the increased programming difficulty in dealing with NT’s superior hardware abstraction model.

This problem plagued the NT line all the way through Windows Programmers complained that it was too hard to write drivers for NT, and hardware developers were not going to go through the trouble of developing drivers for a small segment of the market.

Additionally, although allowing for good performance and fuller exploitation of system resources, it was also resource-intensive on limited hardware, and thus was only suitable for larger, more expensive machines.

However, these same features made Windows NT perfect for the LAN server market which in was experiencing a rapid boom, as office networking was becoming common. Windows NT version 3. The Win32 API had three levels of implementation: the complete one for Windows NT, a subset for Chicago originally called Win32c missing features primarily of interest to enterprise customers at the time such as security and Unicode support, and a more limited subset called Win32s which could be used on Windows 3.

Thus Microsoft sought to ensure some degree of compatibility between the Chicago design and Windows NT, even though the two systems had radically different internal architectures.

Windows NT was the first Windows operating system based on a hybrid kernel. The hybrid kernel was designed as a modified microkernel , influenced by the Mach microkernel developed by Richard Rashid at Carnegie Mellon University, but without meeting all of the criteria of a pure microkernel. As released, Windows NT 3. The 3. Support for Windows NT 3. After Windows 3.

The Win32 API first introduced with Windows NT was adopted as the standard bit programming interface, with Win16 compatibility being preserved through a technique known as ” thunking “.

A new object-oriented GUI was not originally planned as part of the release, although elements of the Cairo user interface were borrowed and added as other aspects of the release notably Plug and Play slipped. Microsoft did not change all of the Windows code to bit; parts of it remained bit albeit not directly using real mode for reasons of compatibility, performance, and development time.

Additionally it was necessary to carry over design decisions from earlier versions of Windows for reasons of backwards compatibility, even if these design decisions no longer matched a more modern computing environment.

These factors eventually began to impact the operating system’s efficiency and stability. Microsoft marketing adopted Windows 95 as the product name for Chicago when it was released on August 24, Microsoft had a double gain from its release: first, it made it impossible for consumers to run Windows 95 on a cheaper, non-Microsoft DOS, secondly, although traces of DOS were never completely removed from the system and MS DOS 7 would be loaded briefly as a part of the booting process, Windows 95 applications ran solely in enhanced mode, with a flat bit address space and virtual memory.

These features make it possible for Win32 applications to address up to 2 gigabytes of virtual RAM with another 2 GB reserved for the operating system , and in theory prevented them from inadvertently corrupting the memory space of other Win32 applications.

Three years after its introduction, Windows 95 was succeeded by Windows Unlike with Windows 3. Microsoft case, blaming unfair marketing tactics on Microsoft’s part. Some companies sold new hard drives with OSR2 preinstalled officially justifying this as needed due to the hard drive’s capacity.

The first Microsoft Plus! Microsoft ended extended support for Windows 95 on December 31, Microsoft released the successor to NT 3.

It was Microsoft’s primary business-oriented operating system until the introduction of Windows Microsoft ended mainstream support for Windows NT 4. Both editions were succeeded by Windows Professional and the Windows Server Family, respectively.

This edition was succeeded by Windows XP Embedded. On June 25, , Microsoft released Windows 98 code-named Memphis , three years after the release of Windows 95 , two years after the release of Windows NT 4. USB support in Windows 98 is marketed as a vast improvement over Windows The release continued the controversial inclusion of the Internet Explorer browser with the operating system that started with Windows 95 OEM Service Release 1. The action eventually led to the filing of the United States v.

Microsoft case, dealing with the question of whether Microsoft was introducing unfair practices into the market in an effort to eliminate competition from other companies such as Netscape.

In , Microsoft released Windows 98 Second Edition, an interim release. One of the more notable new features was the addition of Internet Connection Sharing , a form of network address translation , allowing several machines on a LAN Local Area Network to share a single Internet connection. Hardware support through device drivers was increased and this version shipped with Internet Explorer 5.

Many minor problems that existed in the first edition were fixed making it, according to many, the most stable release of the Windows 9x family. Mainstream support for Windows 98 and 98 SE ended on June 30, , and ended extended support on July 11, It has the version number Windows NT 5.

Windows has had four official service packs. It was successfully deployed both on the server and the workstation markets. Amongst Windows ‘s most significant new features was Active Directory , a near-complete replacement of the NT 4. Terminal Services , previously only available as a separate edition of NT 4, was expanded to all server versions.

A number of features from Windows 98 were incorporated also, such as an improved Device Manager, Windows Media Player , and a revised DirectX that made it possible for the first time for many modern games to work on the NT kernel. Windows is also the last NT-kernel Windows operating system to lack product activation. While Windows upgrades were available for Windows 95 and Windows 98, it was not intended for home users. It was the last DOS-based operating system from Microsoft.

Windows Me introduced a new multimedia-editing application called Windows Movie Maker , came standard with Internet Explorer 5. System Restore was a notable feature that would continue to thrive in all later versions of Windows. Windows Me was conceived as a quick one-year project that served as a stopgap release between Windows 98 and Windows XP.

Many of the new features were available from the Windows Update site as updates for older Windows versions System Restore and Windows Movie Maker were exceptions.

Windows Me was criticized for stability issues, as well as for lacking real mode DOS support, to the point of being referred to as the “Mistake Edition. The initial release was met with considerable criticism , particularly in the area of security , leading to the release of three major Service Packs.
