A DtsProperties collection is a collection of DtsProperty objects.

The following code example creates a DtsEventHandler for the OnError event in the package. This DtsEventHandler container contains two executables and establishes a precedence constraint between them. The code example displays retrieves the DtsProperties collection from the DtsEventHandler container, and displays names and property types.
