EventTrigger.ValueQueries As String

Property value

A collection of of name-value pairs. Each name-value pair in the collection defines a unique name for a property value of the event that triggers the event trigger. The property value of the event is defined as an XPath event query. For more information about XPath event queries, see Event Selection.


The name of the query can be used as a variable in the following action properties:

The following code example strings show two name value pairs that can be used in a name-value collection. The values returned by the XPath queries can replace variables in an action's property. The values are referenced by name, with $(user) and $(machine), in the action property. For example, if the $(user) and $(machine) variables are used in the ShowMessageAction.MessageBody string, then the value of the XPath queries will replace the variables in the string.

name: user
value: Event/UserData/SubjectUserName

name: machine
value: Event/UserData/MachineName

For more information about writing a query string for certain events, see Event Selection and Subscribing to Events.
