A wrapper function is a function (another word for a subroutine) in a software library or a computer program whose main purpose is to call a second subroutine [1] or a system call with little or no additional computation. Wrapper functions simplify writing computer programs by abstracting the details of a subroutine's implementation.
It also introduced the ability to write non-GUI classes in Visual Basic. With VB4 the language was separated from the GUI library, and made available as VBA, in which form it was embedded with the Office 95 suite. To ease migration of Office macros and scripts, features from WordBasic, Excel Basic and Access Basic were incorporated into the ...
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.

In SQL, the TRUNCATE TABLE statement is a data manipulation language (DML) [1] operation that deletes all rows of a table without causing a triggered action. The result of this operation quickly removes all data from a table , typically bypassing a number of integrity enforcing mechanisms.
Depending on what type of data validation a program or operating system has, the data may be truncated silently (i.e., without informing the user), ...
The validation functions allow one to test whether a conversion would fail, and change the program's flow of control in an if statement.) True indicates that conversion would be possible, False indicates that it would not be. Similarly the type checking functions return a Boolean recording whether the argument expression is of a particular type.
Libwww is an early World Wide Web software library providing core functions for web browsers, implementing HTML, HTTP, and other technologies. Tim Berners-Lee, at the European Organization for Nuclear Research (), released libwww (then also called the Common Library) in late 1992, comprising reusable code from the first browsers (WorldWideWeb and Line Mode Browser).
