Dynamic Array problem

[Werner]

Hi,

I want to put data in a dynamic Array with a looping. If I use a
variable to change the position in my vurtual dynamic array,it gives me
an error saying I am out of range. The solution I've found and tried in
other posts is to redim the array, but by doing so I loose all the
other datas from the previous positions (other than the actual position
redimed). SO is there a way make my dynamic array works?

Thanks!

Sub Age_moyenne_ponderee()

'Je déclare es tableaux et mes variables que j'aurai besoin pour
incrémenter.
Dim tabdynamique() As Double
Dim I As Long
Dim J As Variant
J = 0
Dim Z As Integer

' Age looping. Le principe est que la boucle effectue le calcul sur la
ligne la ligne si _
elle voit qu'elle n'est pas vide et change de ligne une fois la
suppression _
de la ligne effectuée.

For I = 12 To 65536

If Worksheets("Formulaire").Range("A" & I).Value <> "" Then

J = J + 1
ReDim tabdynamique(J)
tabdynamique(J) = (((Worksheets("Formulaire").Range("E" &
I).Value) / (Worksheets("Formulaire").Range("R5").Value)) *
(Worksheets("Formulaire").Range("H" & I).Value))

Sheets("Formulaire").Range("AF" & I).Value =
tabdynamique(J)
Else
Exit For
End If
Next I

End Sub

Try REDIM PRESERVE

From VB Help:
Preserve (Optional Keyword) used to preserve the data in an existing
array when you change the size of the last dimension.

Does that help?

Hi Ron,

Thanks for your try but unfortunetaly, the values are not retained i
the array even with redim preserve.

Any other idea?

Lets see your new code (please enclose it in 'code' tags)

Thanks

Hi,

Here's my new code. It says I am out of range at line:
ReDim Preserve tabdynamique(UBound(tabdynamique) + 1)

Note that I use Excel 97. Could it be part of an unsupported feature
for this version of VBA?

Regards,

Werner

The problem is the first time you try and redim the array has no
dimension.

So this will fail

Code:
--------------------

UBound(tabdynamique)
--------------------


Try this
