Examples

The following example searches through the enhancement stream until it finds a trigger event. When it finds a trigger, it stores the trigger's handle in an array.

Dim num As Integer
Dim TrigArray() As Long
ReDim TrigArray(0 To evs.Count - 1)
 
For Each e in evs
    If (e.IsTrigger) Then
        TrigArray(num) = e.Handle
        num = num + 1
    End If
Next e
 

The reason that the handle is stored instead of the trigger's index value, is that the handle uniquely identifies the trigger and does not change. Because the collection is sorted by start time, the trigger's index value can change as events are added or deleted.
