templated array as function parameters
 

Hello, I am writing some code to test whether an array is undefined (See
code below). I am passing an array of integers to the function right now,
and I am wondering if i can extend this so that it can be apply to array of
any type (even user defined type). Something like a function template.




Public Function isUndefArray(ByRef a() As integer) As Boolean
Dim l As Long
On Error Resume Next
l = UBound(a)
If Err.Number = 9 Then
Debug.Print Err.Description

isUndefArray = True
Exit Function
End If
isUndefArray = False
End Function

templated array as function parameters
 

I think this will work for any type of array:

''Returns True is the passed array has been dimensioned else False
Function ArrayDimmed(vntArray As Variant) As Boolean
On Error Resume Next
ArrayDimmed = IsNumeric(UBound(vntArray))
End Function
