remove element from an anrray

[dpimental]

Is there a way to remove an element from an array?
given the following ....

Dim arrTest (1 to 5) as int

arTest(1) = 1
arTest(2) = 2
arTest(3) = 3
arTest(4) = 4
arTest(5) = 5

How can I remove element 3 and resize the array such as this ...

arTest(1) = 1
arTest(2) = 2
arTest(3) = 4
arTest(4) = 5

I know I can do this in other languages. Can it be done in VB?

Not without, redimensioning the array and
redefining each element.

A collection on the other hand, does allow you to insert
and remove at will, in one manoeuvre.

For brevity, i'll post you these codes, i got from elsewhere,
I think a sight called "VBA Programmer"

Sub PlaceNewItem()
Dim vCollection As New Collection, x As Integer, sKey As Variant

sKey = Array("One", "two", "three", "four", "Five")

For x = 1 To UBound(sKey)
vCollection.Add sKey(x)
Next x

vCollection.Add 6, , 2 'places in the index, where to add new item. either before argument or after

For x = 1 To vCollection.Count
Debug.Print vCollection(x)
Next x


End Sub

Sub RemoveItem()
Dim vCollection As New Collection, x As Integer, sKey As Variant

sKey = Array("One", "two", "three", "four", "Five")

For x = 1 To UBound(sKey)
vCollection.Add sKey(x)
Next x

vCollection.Remove 2 'redimensions, automatically

For x = 1 To vCollection.Count
Debug.Print vCollection(x)
Next x


End Sub

That's what I thought. Is a collection like a dictionary? And does it only contain 2 elements, a key and a value?

after a little research, apparently it is.
This site may enlighten you a little further,
as it did me.

A collection does contain only two values ... an item and (optionally) a key. The "item" can be just about anything however. For example, an instance of a user-defined class, an object, a TypeDef, etc. Collections and dictionary objects have some similarities but dictionary objects have considerably more flexibility and are usually faster than collections.
