Altering Size of Arrays

[TNT]

How would I alter the size of an array at run-time? I want to read the list of processes and stick each one into a slot in an array, but the number of processes can change alot.

Take a look at ReDim

Take a look at ReDim

If u r using redim then must have a lok on preserve kwd also
dim myArray() as string
myarray(0)="XYZ "
Redim Preserve myArray(10)

dim myArray() as string
myarray(0)="XYZ "
Redim Preserve myArray(10)

This is not normally correct. The preserve version is only used if you want to increase the size of the array while retaining the original contents. It is not used if you simply want to dynamically size the array at run time.

I've just given the idea

Not just the idea.
This code will not work. You will get a 'subscript out of range' error

dim myArray() as string
myarray(0)="XYZ"

So what code will work?

When you are going to dynamically size an array you would follow this pattern:

Dim ar() As Integer
Dim size As Integer

size = 25
ReDim ar(size)

If you already have an array with data stored in it and you wish to resize it to accept more data:

size = 35
ReDim Preserve ar(size)
