Dynamic Arrays

to use it when the number of elements to a dimension of the array are not the same. Dim

ArrayDinamic () 'leave empty parenthesis


recontar_items


Sub ReDim Array (a)' to allocate the array space


Array (a) = 34 * eye but no values


will be kept 'if we keep the values \u200b\u200bReDim Preserve

emplaremos arrayName (number) = value

ReDim Preserve Array (a) = 34' retain values \u200b\u200b
End sub



The ReDim statement to change the number elements of the array, not the number of dimensions.

For example, if the array_A declare a module level. Private


Array_A () as Integer

array to allocate space to use: ReDim

Array_A (5)

Whenever ReDim statement is executed, all values \u200b\u200bstored in the array are lost. When you want to change the size of array preserving the values \u200b\u200bof the array,

use the keyword ReDim Preserve. For example



Array_A ReDim Preserve (8)

Arrays Using an array we refererir to a "number of elements" for a "same name" and referenced an element of the series for a number of index.

ArraySuperClubes (1) = "Real Madrid"
ArraySuperClubes (2) = "Barcelona"
ArraySuperClubes (3) = " Milan "
ArraySuperClubes (4) =" Inter Milan of "
ArraySuperClubes (5) =" Manchester United "

In this example we'll prove more clearly

1 ) We refer to a number of items by the same name in this case will ArraySuperClubes .

suffice For example something like sgte instruction to load the elements of our in a control array listbox 1

represents ArraySuperClubes 5 elements of our array

listbox 1. list ArraySuperClubes =

2) Referenced an element of the series for a number of index. For example



If we wanted reference to the element "3" of our ArraySuperClubes () Msgbox

ArraySuperClubes (3)

note: As with the variable declaration must have
account
Arrays of variables ( static )
means that our array shall a fixed number of items here

is important to consider the scope array declaration of
as is done with the variables on a daily basis . That is

-level procedure, module or pubic (available for the entire project)

Examples: Dim

_ Array Spain (20) as string

' pled an array of 21 items ranging from zero index ..

_ Array Portugal (0), Array
_ Portugal (1), Array
_ Portugal (21)

Dim ArrayBidimensionalXy (1 to 4 , for a 4) the integer

'was declared 2 dimensional array

ArrayBidimensional with 4 * 4 elements ArrayBidimensional (1.1) ... ArrayBidimensional (4.4)

Public New _X (1 To 20) The String * 20 Public

New _X (1) ... Public New _X (20),
each element can store a string (20 characters).
