When you handle the ItemClick event VB generates a method to handle the event, like this:

    Private Sub ultraExplorerBar1_ItemClick(ByVal sender As Object, ByVal e As ItemEventArgs) Handles ultraExplorerBar1.ItemClick

    End Sub

You can call this directly by creating an instance of the ItemEventArgs class and passing it to that method, like this:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim someItem As UltraExplorerBarItem = Me.ultraExplorerBar1.Groups(0).Items(0)
        Dim eventArgs As New ItemEventArgs(someItem)
        Me.ultraExplorerBar1_ItemClick(Me.ultraExplorerBar1, eventArgs)
    End Sub

Thus simulating a firing of the event.

Thanks for the input.  Would it be possible to explain it in a way that a slightly less experienced person would understand.

Thanks
