How can we retain values in an array without destorying previous values - kotaramamohana - 06-22-2012

Hi Friends,

suppose we have stored 5 values in array. Later we decided to increase array size without destorying previous values. Is it possible to do that. If yes, Can you please share how can we do that?

For your understanding i am giving one Example:

Code:
a=array("a","b","c","d","e")

msgbox a(0)  'It displays a

ReDim a(15)

msgbox a(0)  'it displays empty value (How can I retain a(0) value)

You need to preserve the array elements using preserve keyword.

Use

Redim Preserve a(15)

Use "Preserve" keyword to retain value

Below is the example

Code:
a=array("a","b","c","d","e")

msgbox a(0)  'It displays a

 ReDim Preserve a(15)

msgbox a(0)  'it retains value
