[RESOLVED] Clearing a Structure

Hi trying to check I have cleared this correctly. Seems to have worked byt I seem to get anomolies somethimes that might have nothing to do with the clear part.

I declare the structure. Dimension it, then when I need to clear call the Sub to clear it.

1) Will this clear it all, including the array within the structure?

2) Incidentally I dimension it after as it is here in the example. Is there a way of doing it when actually needed so I have a better idea of how many items to allocate as opposed to an arbitrary number as here in the example of 30?

Code:

---

    Structure TestList
        Dim TL_name As String
        Dim TL_total As Integer
        Dim TL_Sub_total_Array() As Integer
        Dim TL_reference As Integer
    End Structure

    Dim TotalList(30) As TestList

    Private Sub Clear_Rows_Display()
        Dim count1 As Integer
        For count1 = 0 To TestList.GetUpperBound(0)
            Array.Clear(TestList, 0, count1)
        Next
    End Sub

Thanks in advance.

Use an array list instead. Then just .Add to it as you need to.

EDIT: Changed to Framework 2.0 link.

i always erased my arrays with a ReDim but you have to declare it as dynamic to do that.
That page states that the information on it is for .net 3.0
that distributable is currently Beta. some people have it but it won't even be available on all OS.

if you don't know how, here's an example of redimming

Code:

---

Structure TestList
        Dim TL_name As String
        Dim TL_total As Integer
        Dim TL_Sub_total_Array() As Integer
        Dim TL_reference As Integer
    End Structure
    dim TotalList() as Testlist 'dims it dynamic
    ReDim TotalList(30) As TestList'sets it to size

    Private Sub Clear_Rows_Display()
    redim TotalList(30) as testlist 'erases it
    '  Redim preserve totallist(3) as testlist 'Doesn't erase it
    End Sub

You're right. The MSDN search turns up articles for all versions and I clicked on the 3.0 version. Changed.

If you are using .NET 2.0 then use a List(Of TestList) instead.

Thank you for your replies.

Got it sorted now(i think).
