This function determines whether the variable name passed as its argument is an array. Uninitialized arrays will, note, return False from this function in Visual Basic .NET. [7] In Visual Basic 6, arrays are not reference types, and an uninitialized array will return True from this function just like an initialized array. [8] IsDate(expression)
VBA 5.0 was launched in 1997 along with all of MS Office 97 products. The only exception for this was Outlook 97 which used VBScript. VBA 6.0 and VBA 6.1 were launched in 1999, notably with support for COM add-ins in Office 2000. VBA 6.2 was released alongside Office 2000 SR-1.
Immediately invoked function expressions may be written in a number of different ways. [3] A common convention is to enclose the function expression – and optionally its invocation operator – with the grouping operator, [4] in parentheses, to tell the parser explicitly to expect an expression.
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
Visual Basic 5.0 also introduced the ability to create custom user controls, as well as the ability to compile to native Windows executable code, speeding up calculation-intensive code execution. A free, downloadable Control Creation Edition was also released for creation of ActiveX controls .

Modules have a function, context, and logic: [117] The function of a module is what it does. The context of a module are the elements being performed upon. The logic of a module is how it performs the function. The module's name should be derived first by its function, then by its context. Its logic should not be part of the name. [117]
APT (Automatically Programmed Tool) [1] is a high-level computer programming language most commonly used to generate instructions for numerically controlled machine tools. Douglas T. Ross [ 2 ] is considered by many to be the father of APT: as head of the newly created Computer Applications Group of the Servomechanisms Laboratory at MIT in 1956 ...
