As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use. Important messages could be signalled by striking the bell on the teletype. This was carried over on PCs by generating a buzz sound. 4 Line feed is used for "end of line" in text files on Unix / Linux systems.
In the above example, a UI element called MainWindow is declared as a subclass of the built-in Window class. The XAML file defines the layout, which in this example is a vertical collection of controls - a textblock outlining instructions to the user, a textbox for the user to type their name, a button to submit, and a results text block.
In computing, Microsoft's ActiveX Data Objects (ADO) comprises a set of Component Object Model (COM) objects for accessing data sources. A part of MDAC (Microsoft Data Access Components), it provides a middleware layer between programming languages and OLE DB (a means of accessing data stores, whether databases or not, in a uniform manner).
This was the source of many out-by-one errors in Visual Basic programs, especially when dealing with interoperability across program library boundaries. Although the .NET Common Language Runtime can support arrays with any base value, Visual Basic .NET and C# provide only zero-based arrays and lists, and the .NET Common Language Specification ...
Like Visual C#, Visual Basic also supports the Visual Studio Class designer, Forms designer, and Data designer among others. Like C#, the VB.NET compiler is also available as a part of .NET Framework, but the language services that let VB.NET projects be developed with Visual Studio, are available as a part of the latter.
For example, one could create a function that creates an infinite list (often called a stream) of Fibonacci numbers. The calculation of the n -th Fibonacci number would be merely the extraction of that element from the infinite list, forcing the evaluation of only the first n members of the list.
The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running. Programs can access API functionality via shared-library technologies or via system-file access. [disputed – discuss]
