Listbox maximum items 1

[jecairns]

This sounds like a theoretical question, but does anyone know the maximum items allowed in a listbox? (similar to a textbox's maxlength of 32767 characters)

Thanks in advance,

Well - I'm not sure - it doesn't appear so.

I just ran the following code and stopped it myself (using breakpoint on the Add line).

While True
    Try
        ListBox1.Items.Add("test")
    Catch ex As Exception
        MsgBox(ListBox1.Items.Count)
        Exit Sub
    End Try
End While

At my final breakpoint the count was 1030625. It probably uses something like a collection or hashtable to store the items - in which case it would only be limited by memory.

Thank you very much-what a simple way to test it-my brain must not be working today.
