String redimming

[pmclinn]

I have a string(10) array.

I want to redim it so that I only have the last 9 strings in the array.
What is the best way to do this?
Example:
String(0) = Dog
String(1) = Cat
String(2) = Bird

I want the cat, and bird to remain and drop the dog from the array....

Something like this might help, although it's hardcoded:

Dim str(5)
str(0) = "Dog"
str(1) = "Bird"
str(2) = "Cat"
str(3) = "Horse"
str(4) = "Lion"

Dim x
For x = 0 To 3
str(x) = str(x + 1)
Next
str(4) = ""
ReDim Preserve str(4)

Using 'ReDim Preserve' you can only remove items from the end of the array.
However, you can use 'Array.Copy' to create a copy of the array and then
discard the original array.

pmclinn,
In addition to the other comments.

Rather then use an Array, consider using an ArrayList (.NET 1.0 & 1.1) or
List(Of T) (.NET 2.0).

Then you can use ArrayList.RemoveAt(0) or List(Of String).RemoveAt(0) to
remove the first element in the "array".

Something like:

' VB 2003 syntax
Dim list As New ArrayList
list.Add("Dog")
list.Add("Cat")
list.Add("Bird")
list.RemoveAt(0)

' VB 2005 syntax
Dim list As New List(Of String)
list.Add("Dog")
list.Add("Cat")
list.Add("Bird")
list.RemoveAt(0)

List(Of T) (.NET 2.0).

And since you are only using strings, try StringCollection (under the
System.Collections.Specialized namespace) :)

HTH,

Mythran,
Yes!

StringCollection is a very good option in this case, as it covers .NET 1.0,
1.1 & 2.0!
