Re: array.reverse
Hello, Wilfredo:
You have a sample of how to do that in http://msdn.microsoft.com/library/de...ssorttopic.asp.
Regards.

Re: array.reverse
This works just fine;-
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Dim myArray() As String = {"hello", "My", "Friend"}
Dim i As Integer
'Prints forward
For i = 0 To myArray.Length - 1
Debug.WriteLine (myArray(i))
' Next reverse array
myArray.Reverse (myArray)
'Prints reverse of original order using same loop as before
For i = 0 To myArray.Length - 1
Debug.WriteLine (myArray(i))
Next
End Sub
'============== =============== ===========
