AOHell was a Windows application that was used to simplify ' cracking ' (computer hacking) using AOL . The program contained a very early use of the term phishing . It was created by a teenager under the pseudonym Da Chronic, whose expressed motivation was anger that child abuse took place on AOL without being curtailed by AOL administrators.
80-451: AOHell was the first of what would become thousands of programs designed for hackers created for use with AOL. In 1994, seventeen year old hacker Koceilah Rekouche, from Pittsburgh, PA, known online as "Da Chronic", used Visual Basic to create a toolkit that provided: a new DLL for the AOL client, a credit card number generator, email bomber, IM bomber, Punter, and a basic set of instructions. It
160-414: A formal language . Languages usually provide features such as a type system , variables , and mechanisms for error handling . An implementation of a programming language is required in order to execute programs, namely an interpreter or a compiler . An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced
240-406: A heap and automatic garbage collection . For the next decades, Lisp dominated artificial intelligence applications. In 1978, another functional language, ML , introduced inferred types and polymorphic parameters . After ALGOL (ALGOrithmic Language) was released in 1958 and 1960, it became the standard in computing literature for describing algorithms . Although its commercial success
320-400: A logic called a type system . Other forms of static analyses like data flow analysis may also be part of static semantics. Programming languages such as Java and C# have definite assignment analysis , a form of data flow analysis, as part of their respective static semantics. Once data has been specified, the machine must be instructed to perform operations on the data. For example,
400-447: A data type whose elements, in many languages, must consist of a single type of fixed length. Other languages define arrays as references to data stored elsewhere and support elements of varying types. Depending on the programming language, sequences of multiple characters, called strings , may be supported as arrays of characters or their own primitive type . Strings may be of fixed or variable length, which enables greater flexibility at
480-399: A fake account generator. In the manual, the creator of AOHell claims that he created the program because the AOL administrators would frequently shut down hacker and warez chatrooms for violation of AOL's terms of service while refusing to shut down the pedophilia chat rooms which regularly traded child pornography . "Da Chronic" claimed that when he confronted AOL's TOSAdvisor about it, he
560-558: A layer to the execution environment. VB applications require the Microsoft VB runtime MSVBVM##.DLL, where ## is a version number, either 50 or 60. MSVBVM60.dll comes standard with Windows in all editions from Windows 98 to Windows 11 although some editions of Windows 7 do not include it. For Windows 95 however the application installation process requires the DLL needed by the program. VB 5 and 6 can compile code to either native or P-Code but
640-416: A list of warez ( illegally copied software) contained in their mailbox. Simply messaging the bot with the titles of the desired software packaging would result in those packages being forwarded to one's mailbox. Since the data merely had to be copied into another user's mailbox (while still residing on an AOL server), the piracy was only limited by how fast messages could be forwarded, with AOL paying for all
720-422: A meaning to a grammatically correct sentence or the sentence may be false: The following C language fragment is syntactically correct, but performs operations that are not semantically defined (the operation *p >> 4 has no meaning for a value having a complex type and p->im is not defined because the value of p is the null pointer ): If the type declaration on the first line were omitted,
800-526: A programmable form system for Windows 3.0 , under the code name Ruby (no relation to the later Ruby programming language ). Tripod did not include a programming language at all. Microsoft decided to combine Ruby with the Basic language to create Visual Basic. The Ruby interface generator provided the "visual" part of Visual Basic, and this was combined with the "EB" Embedded BASIC engine designed for Microsoft's abandoned "Omega" database system. Ruby also provided
880-770: A programmer can develop a simple program without writing much code. Programs built with earlier versions suffered performance problems, but faster computers and native code compilation made this less of an issue. Since a VB program is compiled as a native code executable instead of interpreted as old BASIC variants, it runs relatively fast and requires relatively little storage space. But, from version 5 on , it requires relatively large library files to be loaded at runtime; about 1 MB. Core runtime libraries are included by default in Windows 2000 and later, but extended runtime components require extra installation consideration. Earlier versions of Microsoft Windows (95/98/NT), require

#1732791908014960-608: A wide variety of uses. Many aspects of programming language design involve tradeoffs—for example, exception handling simplifies error handling, but at a performance cost. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Programming languages differ from natural languages in that natural languages are used for interaction between people, while programming languages are designed to allow humans to communicate instructions to machines. The term computer language

The existence of AOHell and similar software even allowed AOL to develop its own warez community. Lurking in secret chat rooms with names such as 'AirZeraw', mm, cerver, 'wArEzXXX', g00dz, 'punter', 'gif', 'coldice', 'GRiP', and 'trade', AOHell created bots , often referred to as 'servers', which would send out
1120-406: Is a set of allowable values and operations that can be performed on these values. Each programming language's type system defines which data types exist, the type of an expression , and how type equivalence and type compatibility function in the language. According to type theory , a language is fully typed if the specification of every operation defines types of data to which the operation
1200-415: Is allowed, the fewer type errors can be detected. Early programming languages often supported only built-in, numeric types such as the integer (signed and unsigned) and floating point (to support operations on real numbers that are not integers). Most programming languages support multiple sizes of floats (often called float and double ) and integers depending on the size and precision required by
1280-419: Is applicable. In contrast, an untyped language, such as most assembly languages , allows any operation to be performed on any data, generally sequences of bits of various lengths. In practice, while few languages are fully typed, most offer a degree of typing. Because different types (such as integers and floats ) represent values differently, unexpected results will occur if one type is used when another
1360-528: Is automatically called that executes the code that the programmer attached to the handler. For a DLL, the VB code generally provides no user interface, and instead provides COM objects to other programs. This allows for capabilities such as server-side processing or an add-in module. Via the COM technology, unused memory is recovered for reuse using reference counting ; recovering when the count reaches zero. VB reduces
1440-472: Is best covered in the last MSDN release before Visual Studio.NET 2002. Later releases of MSDN focused on .NET development and had significant parts of the Visual Basic 6.0 programming documentation removed as the language evolved, and support for older code ended. Although vendor support for Visual Basic 6 has ended, and the product has never been supported on the latest versions of Windows, key parts of
1520-469: Is expected. Type checking will flag this error, usually at compile time (runtime type checking is more costly). With strong typing , type errors can always be detected unless variables are explicitly cast to a different type. Weak typing occurs when languages allow implicit casting—for example, to enable operations between variables of different types without the programmer making an explicit type conversion. The more cases in which this type coercion
1600-484: Is not case-sensitive – though the IDE transforms keywords into a standard case and variable names to match the case used elsewhere in the project. Of note, string comparison is case sensitive by default. The VB compiler is shared with other Visual Studio suite languages, C and C++. Nevertheless, by default the restrictions in the IDE do not allow creation of some targets (Windows model DLLs) and threading models, but over
1680-403: Is often used to specify the execution semantics of languages commonly used in practice. A significant amount of academic research goes into formal semantics of programming languages , which allows execution semantics to be specified in a formal manner. Results from this field of research have seen limited application to programming language design and implementation outside academia. A data type

#17327919080141760-444: Is sometimes used interchangeably with "programming language". However, usage of these terms varies among authors. In one usage, programming languages are described as a subset of computer languages. Similarly, the term "computer language" may be used in contrast to the term "programming language" to describe languages used in computing but not considered programming languages – for example, markup languages . Some authors restrict
1840-474: Is stored. The simplest user-defined type is an ordinal type whose values can be mapped onto the set of positive integers. Since the mid-1980s, most programming languages also support abstract data types , in which the representation of the data and operations are hidden from the user , who can only access an interface . The benefits of data abstraction can include increased reliability, reduced complexity, less potential for name collision , and allowing
1920-442: Is the potential for errors to go undetected. Complete type inference has traditionally been associated with functional languages such as Haskell and ML . With dynamic typing, the type is not attached to the variable but only the value encoded in it. A single variable can be reused for a value of a different type. Although this provides more flexibility to the programmer, it is at the cost of lower reliability and less ability for
2000-402: Is used (in languages that require such declarations) or that the labels on the arms of a case statement are distinct. Many important restrictions of this type, like checking that identifiers are used in the appropriate context (e.g. not adding an integer to a function name), or that subroutine calls have the appropriate number and type of arguments, can be enforced by defining them as rules in
2080-481: Is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (for grammatical structure). Below is a simple grammar, based on Lisp : This grammar specifies the following: The following are examples of well-formed token sequences in this grammar: 12345 , () and (a b c232 (1)) . Not all syntactically correct programs are semantically correct. Many syntactically correct programs are nonetheless ill-formed, per
2160-557: The CPU that performs instructions on data is separate, and data must be piped back and forth to the CPU. The central elements in these languages are variables, assignment , and iteration , which is more efficient than recursion on these machines. Many programming languages have been designed from scratch, altered to meet new needs, and combined with other languages. Many have eventually fallen into disuse. The birth of programming languages in
2240-534: The Component Object Model (COM) technology. VB was first released in 1991. The final release was version 6 (VB6) in 1998. On April 8, 2008, Microsoft stopped supporting the VB6 IDE, relegating it to legacy . The Microsoft VB team still maintains compatibility for VB6 applications through its "It Just Works" program on supported Windows operating systems. Microsoft significantly changed VB for
2320-410: The .NET technology and rebranded it Visual Basic .NET (VB.NET), and then later rebranded it back to Visual Basic . Therefore, Visual Basic can refer to a classic version, a .NET version or both. This article is about the versions before .NET. Just as BASIC was originally intended to be easy to learn, Microsoft intended the same for VB. Development of a VB application is exclusively supported via
2400-455: The 1950s was stimulated by the desire to make a universal programming language suitable for all machines and uses, avoiding the need to write code for different computers. By the early 1960s, the idea of a universal language was rejected due to the differing requirements of the variety of purposes for which code was written. Desirable qualities of programming languages include readability, writability, and reliability. These features can reduce
2480-434: The IDE is organized as a project which can be configured to output as a program ( EXE ), a dynamic-link library (DLL) or an ActiveX control library (OCX) which is a specialized a DLL. Controls provide the graphical functionality of a GUI application, and programmers attach code to event handlers to perform actions. For example, a drop-down control displays a list of items. When the user selects an item, an event handler

2560-630: The VB integrated development environment (IDE) – an application in the Visual Studio suite of tools of that era. Unlike modern versions of Visual Studio that support many languages including VB (.NET), the VB IDE supports just VB. In 2014, some software developers still preferred Visual Basic 6.0 over its successor, Visual Basic .NET . Visual Basic 6.0 was selected as the most dreaded programming language by respondents of Stack Overflow 's annual developer survey in 2016, 2017, and 2018. As

Microsoft developed many derivatives of VB (classic), including: Versions before 5 compiled the code to P-Code – which is interpreted at runtime. The benefits of P-Code include portability and smaller binary file sizes, but it usually slows execution, since an interpreter adds
2720-487: The code is reached; this is called finalization. There is a tradeoff between increased ability to handle exceptions and reduced performance. For example, even though array index errors are common C does not check them for performance reasons. Although programmers can write code to catch user-defined exceptions, this can clutter a program. Standard libraries in some languages, such as C, use their return values to indicate an exception. Some languages and their compilers have
2800-402: The cost of increased storage space and more complexity. Other data types that may be supported include lists , associative (unordered) arrays accessed via keys, records in which data is mapped to names in an ordered structure, and tuples —similar to records but without names for data fields. Pointers store memory addresses, typically referencing locations on the heap where other data
2880-408: The cost of readability. Natural-language programming has been proposed as a way to eliminate the need for a specialized language for programming. However, this goal remains distant and its benefits are open to debate. Edsger W. Dijkstra took the position that the use of a formal language is essential to prevent the introduction of meaningless constructs. Alan Perlis was similarly dismissive of
2960-424: The cost of the bandwidth. One additional limitation included an allotted number of email messages which could be sent per day by a particular user account. Botters were able to circumvent this limitation by signing up for a white-list account which was subjected to an unknown probationary period where AOL administrators monitored the account. The existence of software like AOHell provided a parallel 'lite' version of
3040-432: The cost of training programmers in a language, the amount of time needed to write and maintain programs in the language, the cost of compiling the code, and increase runtime performance. Programming language design often involves tradeoffs. For example, features to improve reliability typically come at the cost of performance. Increased expressivity due to a large number of operators makes writing code easier but comes at
3120-414: The count when a variable goes out of scope or when assigned to Nothing . This design prevents memory leaks that plague some, older languages such as C & C++. It differs significantly from the more modern approach of garbage collection . VB provides a large library of utility objects, and it provides basic support for object-oriented programming . Unlike many other programming languages, VB code
3200-516: The design of programming languages, with the most common type ( imperative languages —which implement operations in a specified order) developed to perform well on the popular von Neumann architecture . While early programming languages were closely tied to the hardware , over time they have developed more abstraction to hide implementation details for greater simplicity. Thousands of programming languages—often classified as imperative, functional , logic , or object-oriented —have been developed for

It is possible to get a subset of the development environment working on 32-bit and 64-bit versions of Windows Vista, Windows 7, Windows 8, Windows 10 and Windows 11. Owing to its persistent remaining popularity, third-party attempts to further support it, such as Rubberduck, exist. The following code snippet displays a message box saying "Hello, World!" as

For example, code can be inserted into the form resize event handler to reposition a control so that it remains centered on the form, expands to fill up the form, etc. By inserting code into the event handler for a keypress in a text box, the program can automatically translate the case of the text being entered, or even prevent certain characters from being inserted. Development in

The earliest computers were programmed in first-generation programming languages (1GLs), machine language (simple instructions that could be directly executed by the processor). This code was very difficult to debug and was not portable between different computer systems. In order to improve the ease of programming, assembly languages (or second-generation programming languages —2GLs) were invented, diverging from

Though most of these utilities simply manipulated the AOL interface, some were powerful enough to let almost any curious party anonymously cause havoc on AOL. The first version of the program was released in 1994 by hackers known as Da Chronic, The Rizzer, and The Squirrel. Hi, this
3680-469: The hacker underground that had existed for years before, based around bulletin board systems . Programs like AOHell played an important part in defining the ' script kiddie ', a user who performs basic cracking using simple tools written by others, with little understanding of what they are doing. These types of programs had a tendency to have AOL accounts banned; and so most users were logged on to accounts they had acquired illicitly, either by phishing or

Visual Basic (classic) Visual Basic (VB) before .NET , sometimes referred to as Classic Visual Basic , is a third-generation programming language , based on BASIC , and an integrated development environment (IDE), from Microsoft for Windows known for supporting rapid application development (RAD) of graphical user interface (GUI) applications, event-driven programming and both consumption and development of components via

New computers also allowed more user interaction, which was supported by newer programming languages. Lisp , implemented in 1958, was the first functional programming language. Unlike Fortran, it supported recursion and conditional expressions , and it also introduced dynamic memory management on

In some cases, such programs may exhibit undefined behavior . Even when a program is well-defined within a language, it may still have a meaning that is not intended by the person who wrote it. Using natural language as an example, it may not be possible to assign
4000-417: The languages intended for execution. He also argues that textual and even graphical input formats that affect the behavior of a computer are programming languages, despite the fact they are commonly not Turing-complete, and remarks that ignorance of programming language concepts is the reason for many flaws in input formats. The first programmable computers were invented at the end of the 1940s, and with them,
4080-511: The machine language to make programs easier to understand for humans, although they did not increase portability. Initially, hardware resources were scarce and expensive, while human resources were cheaper. Therefore, cumbersome languages that were time-consuming to use, but were closer to the hardware for higher efficiency were favored. The introduction of high-level programming languages ( third-generation programming languages —3GLs)—revolutionized programming. These languages abstracted away

#17327919080144160-400: The meaning of languages, as opposed to their form ( syntax ). Static semantics defines restrictions on the structure of valid texts that are hard or impossible to express in standard syntactic formalisms. For compiled languages, static semantics essentially include those semantic rules that can be checked at compile time. Examples include checking that every identifier is declared before it
4240-639: The new programming languages uses static typing while a few numbers of new languages use dynamic typing like Ring and Julia . Some of the new programming languages are classified as visual programming languages like Scratch , LabVIEW and PWCT . Also, some of these languages mix between textual and visual programming usage like Ballerina . Also, this trend lead to developing projects that help in developing new VPLs like Blockly by Google . Many game engines like Unreal and Unity added support for visual scripting too. Every programming language includes fundamental elements for describing data and
4320-455: The operations or transformations applied to them, such as adding two numbers or selecting an item from a collection. These elements are governed by syntactic and semantic rules that define their structure and meaning, respectively. A programming language's surface form is known as its syntax . Most programming languages are purely textual; they use sequences of text including words, numbers, and punctuation, much like written natural languages. On
4400-436: The option of turning on and off error handling capability, either temporarily or permanently. One of the most important influences on programming language design has been computer architecture . Imperative languages , the most commonly used type, were designed to perform well on von Neumann architecture , the most common computer architecture. In von Neumann architecture, the memory stores both data and instructions, while
4480-436: The order of execution of key instructions via the use of semaphores , controlling access to shared data via monitor , or enabling message passing between threads. Many programming languages include exception handlers, a section of code triggered by runtime errors that can deal with them in two main ways: Some programming languages support dedicating a block of code to run regardless of whether an exception occurs before
4560-483: The other hand, some programming languages are graphical , using visual relationships between symbols to specify a program. The syntax of a language describes the possible combinations of symbols that form a syntactically correct program. The meaning given to a combination of symbols is handled by semantics (either formal or hard-coded in a reference implementation ). Since most languages are textual, this article discusses textual syntax. The programming language syntax
4640-442: The parsing phase. Languages that have constructs that allow the programmer to alter the behavior of the parser make syntax analysis an undecidable problem , and generally blur the distinction between parsing and execution. In contrast to Lisp's macro system and Perl's BEGIN blocks, which may contain general computations, C macros are merely string replacements and do not require code execution. The term semantics refers to
4720-585: The program would trigger an error on the undefined variable p during compilation. However, the program would still be syntactically correct since type declarations provide only semantic information. The grammar needed to specify a programming language can be classified by its position in the Chomsky hierarchy . The syntax of most programming languages can be specified using a Type-2 grammar, i.e., they are context-free grammars . Some languages, including Perl and Lisp, contain constructs that allow execution during
4800-489: The programmer specifies a desired result and allows the interpreter to decide how to achieve it. During the 1980s, the invention of the personal computer transformed the roles for which programming languages were used. New languages introduced in the 1980s included C++, a superset of C that can compile C programs but also supports classes and inheritance . Ada and other new languages introduced support for concurrency . The Japanese government invested heavily into
4880-417: The programmer. Storing an integer in a type that is too small to represent it leads to integer overflow . The most common way of representing negative numbers with signed types is twos complement , although ones complement is also used. Other common types include Boolean —which is either true or false—and character —traditionally one byte , sufficient to represent all ASCII characters. Arrays are

#17327919080144960-420: The programming language to check for errors. Some languages allow variables of a union type to which any type of value can be assigned, in an exception to their usual static typing rules. In computing, multiple instructions can be executed simultaneously. Many programming languages support instruction-level and subprogram-level concurrency. By the twenty-first century, additional processing power on computers
5040-803: The runtime is still required for built-in functions and forms management. Criticisms of VB (prior to VB.NET) include: All versions of the Visual Basic IDE, from 1.0 to 6.0, are no longer supported by Microsoft. The associated runtime environments are also unsupported, except for the Visual Basic 6 core runtime environment, which Microsoft officially supports for the lifetime of Windows 10 and Windows 11 . Third party components that shipped with Visual Studio 6.0 are not included in this support statement. Some legacy Visual Basic components may still work on newer platforms, despite being unsupported by Microsoft and other vendors.

A tool is used to place controls (e.g., text boxes, buttons, etc.) on the form (window). Controls have attributes and event handlers associated with them. Default values are provided when the control is created, but may be changed by the programmer. Many attribute values can be modified during run time based on user actions or changes in
5200-404: The semantics may define the strategy by which expressions are evaluated to values, or the manner in which control structures conditionally execute statements . The dynamic semantics (also known as execution semantics ) of a language defines how and when the various constructs of a language should produce a program behavior. There are many ways of defining execution semantics. Natural language
5280-686: The so-called fifth-generation languages that added support for concurrency to logic programming constructs, but these languages were outperformed by other concurrency-supporting languages. Due to the rapid growth of the Internet and the World Wide Web in the 1990s, new programming languages were introduced to support Web pages and networking . Java , based on C++ and designed for increased portability across systems and security, enjoyed large-scale success because these features are essential for many Internet applications. Another development

Another usage regards programming languages as theoretical constructs for programming abstract machines and computer languages as the subset thereof that runs on physical computers, which have finite hardware resources. John C. Reynolds emphasizes that formal specification languages are just as much programming languages as are
5440-401: The twenty-first century. Around 1960, the first mainframes —general purpose computers—were developed, although they could only be operated by professionals and the cost was extreme. The data and instructions were input by punch cards , meaning that no input could be added while the program was running. The languages developed at this time therefore are designed for minimal interaction. After
5520-424: The twenty-first century. C allows access to lower-level machine operations more than other contemporary languages. Its power and efficiency, generated in part with flexible pointer operations, comes at the cost of making it more difficult to write correct code. Prolog , designed in 1972, was the first logic programming language, communicating with a computer using formal logic notation. With logic programming,
5600-475: The underlying data structure to be changed without the client needing to alter its code. In static typing , all expressions have their types determined before a program executes, typically at compile-time. Most widely used, statically typed programming languages require the types of variables to be specified explicitly. In some languages, types are implicit; one form of this is when the compiler can infer types based on context. The downside of implicit typing

Visual Basic has notable features and characteristics that are in some cases different than other BASIC variants or from other common languages: BYTE reported in 1989 that, based on its experience with Macintosh software development, Microsoft "wants to provide a development environment that mimics the delivery environment". BASIC's string handling

Among its innovations adopted by later programming languages included greater portability and the first use of context-free , BNF grammar. Simula , the first language to support object-oriented programming (including subtypes , dynamic dispatch , and inheritance ), also descends from ALGOL and achieved commercial success. C, another ALGOL descendant, has sustained popularity into

I once IMed TOSAdvisor and asked him why he closes the Hacker room, but does not close the kiddie porn rooms. He did not reply, instead he cancelled my account. I guess we see where AOL's priorities lie. He also stated that his goal was: [To have] 20,000+ idiots using AOHell to knock people offline, steal passwords and credit card information, and to basically annoy
