nonexisting array-element null value ?

[vb_albion]

Hello girls and others,

Now I have a problem with an (nonexisting) array-element null value (how to get it?).

If i have for instance a 2dimensional array testArray(2, 2) , i need something like:

Sub TestSub()
If testArray(5, 3) = Null Then
MsgBox "Success"
End if
End Sub

but i get error message : "Run-time error '9': Subscript out of range"

Actually, here is an entire test code:

Dim testArray() As Integer        'global

Sub Fill()
Dim k As Integer
Dim w As Integer
k = 100
w = 200
    For t = 0 To 3
        ReDim Preserve testArray(2, t)
        testArray(0, t) = k
        testArray(1, t) = w
        MsgBox testArray(0, t)         'works
        MsgBox testArray(1, t)         'works
        
        k = k + 1
        w = w + 1
    Next t
    
    Call TestSub
End Sub

Sub TestSub()
    If testArray(5, 3) = Null Then
        MsgBox "Yeah"
    End If
End Sub

"Run-time error '9': Subscript out of range"


Thanks
