To Do This

Reorder the contents

of an array

Use methods in the Array class of the .NET Framework. To sort an array

named RandArray in ascending order, use the Array.Sort method as

follows:

Array.Sort(RandArray)

To reverse the order of an array named RandArray, use the Array.Reverse

method as follows:

Array.Reverse(RandArray)

To give the user visual

feedback during long

calculations

Add a ProgressBar control to your form. (You can find the ProgressBar

control on the Common Controls tab of the Toolbox .) Set the Minimum,

Maximum, and Value properties for the control by using program code.

The counter variable in a For... Next loop often offers a good way to set

the Value property.
