In Dis--Array

Hi.

Is there a property that tells you if your Dynamic Array has no elememts in it?

If I use UBound, I get an error for an empty array. There should be a way to do this rather than depending on the Err object.

Thanks for your help.

I use this to parsr a userdefined array
I search for User.nick

Code:

---

Public Function ParseArray() As Boolean
    Dim Loops As Integer
    Dim Username As String
   
    On Error GoTo ArrayErr      ' Error handling enabled
   
    For Loops = 0 To UBound(usr) '- 1
        If InStr(usr(Loops).Nick, Username) Then ParseArray = True
   
    Next Loops
   
    Exit Function

ArrayErr:
   
    If Err.Number = 9 Then
      'Call MsgBox("Empty array", vbInformation)
        ParseArray = False
    Else
      'oops
   
    End If

    On Error GoTo 0            ' Error handling disabled

End Function

It seems like you are using the Err object to detect an empty array. I know how to do that. I was wondering if there was a property or something that would let you know that a Dynamic Array was empty? Or is the Err.Number = 9 the only way?

Thx.

I am pretty sure you are using something like this. But here it goes anyway.

Code:

---

Private Sub Form_Click()
  Dim d(4) As String
  Dim i As Integer
  For i = LBound(d) To UBound(d)
    If d(i) = "" Then Me.Print d(i) & " Empty"
  Next
End Sub

No there isn't, eitherway errorhandling or have a items counter. Also you could go for having option base 1 and use the 1 element array as empty array.

Shark.

I think you mis-understood what I was trying to do. :( Kedaman!! At last, someone understands what I'm talking about! :)

Thanks again.

Well, you know, this topic has been up so many times lately :)

I didn't know...or I wouldn't have asked. :)

I don't know how but what about

Code:

---

IsEmpty(expression)
