[Resolved]Reorganising Arrays...

Well, I need to reorganise my arrays by being able to insert data in at the start, and push everything down which I have done with the following code,

VB Code:

Public RndTracker(19) As String
Public TempArray(19) As String
'---
 
IntCurrindex = tempint   'temp int is a random integer
 
For i = 0 To UBound(RndTracker)
  If i = 0 Then
    Temparray(0) = IntCurrindex
    Temparray(1) = RndTracker(0)
  ElseIf i > 0 Then
    Temparray(i) = RndTracker(i - 1)
  End If
Next i
 
'Copy back
For i = 0 To UBound(Temparray)
RndTracker(i) = Temparray(i)
Next i

The above code works well, but, I want to be able to go back through the array and reorganise it again.. which is where I've managed to get myself confused.

Basically I would need to remove the first item, and then replace it with the second item in the array, and I guess just make the last item in the array zero?

Should be an easy one for you guys (I hope), also just want to check that is the best way of doing it. ;)

Thanks in advance.

VB Code:

For i=1 To UBound(RndTracker)
  RndTracker(i-1)=RndTracker(i)
Next i
RndTracker(UBound(RndTracker))=0

Instead of the last line you could Redim the array to one element less by:

VB Code:

Redim Preserve RndTracker(UBound(RndTracker)-1)

Redim won't work with a fixed array? :confused:

You're right, sorry about that!

I think your code does the same as mine. It moves one item back, but then thats it...unless I've screwed up somewhere...

I think it's the only way to do it!
Mine just doesn't use a second array.

You can slightly speed up the Copy Back part of your code by just saying RndTracker=TempArray, rather than copying each element across.

Your code inserts at the beginning, and copies the first 19 items from the old array below it.

Opus's code moves the last 19 items up one slot, and puts a 0 in the last slot.

The one adds, the other takes away.

You could do your code without the temp array with something like this:

For i = UBound(RndTracker) to 1 Step -1
RndTracker(i)=RndTracker(i-1)
Next i

RndTracker(0) = <whatever that random number was>


That will be somewhat smaller and faster.
Sorry, I can't remember the tags for the code.

Bummer, I gotta remember those tags, that looks like poo.:(

The tags are [ vbcode] [ /vbcode] with out the space before the "v" &"/" ;)

If you can't remember it, then atleast use the Quote tags, so that it stands out. ;)

Thanks guys, I figured out why I couldn't get your code going, something else was screwing up my value. :D

Oh! great something else!!
At least we something to talk about.................
