In Visual Basic, a control array [1] is a group of related controls in a Visual Basic form that share the same event handlers. Control arrays are always single-dimensional arrays, and controls can be added or deleted from control arrays at runtime. One application of control arrays is to hold menu items, as the shared event handler can be used ...
Visual Basic 3.0 was released in the summer of 1993 and came in Standard and Professional versions. VB3 included version 1.1 of the Jet Database Engine that could read and write Jet (or Access) 1.x databases. Visual Basic 4.0 (August 1995) was the first version that could create 32-bit as well as 16-bit Windows programs. It has three editions ...
Visual Basic: Dim name «As type» See notes to left. Constants use the same syntax, and: use Const instead of Dim; have a restriction to only certain primitive types Const name 1 «As type» = value, name 2 «As type» = value, ... Visual Basic .NET [10] The variable declaration syntax of VB.NET is unusually difficult to precisely describe.
Dictionary < ' TKey, ' TValue > type (which is implemented as a hash table), which is the primary associative array type used in C# and Visual Basic. This type may be preferred when writing code that is intended to operate with other languages on the .NET Framework, or when the performance characteristics of a hash table are preferred over ...
In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.
Visual Basic (VB), originally called Visual Basic .NET (VB.NET), is a multi-paradigm, object-oriented programming language, implemented on .NET, Mono, and the .NET Framework. Microsoft launched VB.NET in 2002 as the successor to its original Visual Basic language, the last version of which was Visual Basic 6.0.
Most BASICs supported the construction of array variables using the DIM keyword, for instance, DIM A(5), B(2,2) defines two arrays, the single-dimension A and two-dimension (matrix) B. In Full BASIC, the lower bound of any array was normally 1, so in this case, the variable A has five "slots", numbered 1 though 5.
Arrays can be one or two dimensional using DIM, but only numeric arrays are supported. All variables are normally allocated space in an associated one-dimensional array without using DIM, they are given space for 11 items, indexes 0 to 10. The lower bound for arrays is typically 0, but using OPTION BASE 1 can change the index to 1. [28]
