Syntax

Engine.UIMessagePollingEnabled

Data Type

Boolean

Purpose

Specifies if user interface message polling is enabled.

Remarks

Default value is False .

Set this property to True when writing a user interface which uses polling rather than events to obtain UIMessages from TestStand.

To poll, call the Engine.IsUIMessageQueueEmpty property. If IsUIMessageQueueEmpty returns False , call the Engine.GetUIMessage method to retrieve the next UIMessage . If your development environment requires you to explicitly release COM references, release the COM reference to the previous user interface message before obtaining the next one.
