Is Window Exists Activity

The Is Window Exists activity checks whether a specific window currently exists within a native Windows desktop application, and stores the result as a boolean value for use in conditional logic.

Field	Description	Requirement
Application instance	The reference name of the application instance previously opened or attached.	Required
Element	The JSON-based selector identifying the target window.	Required
Label	An alternative to `Element` that identifies the target window by label instead of a selector.	Optional
Label match type	Defines how `Label` is compared against candidate windows (e.g., `Equals`, `Contains`).	Optional
Retry count	The number of times the activity will retry the check before returning `false`.	Optional
Result variable name	The name of the variable where the boolean result will be stored.	Required

Action Types & Examples

Window Exists Check

Format: boolean
Example Result: false

Implementation Examples

Field Setup - Application instance: ${appInstance} - Element: the target window identified by the UI Automation Inspector - Result variable name: windowExistsResult

Execution Parameters - Retry count: 3

Technical Notes

Label and Label match type provide an alternative to Element for identifying the target window, useful when a stable selector is not available. Increasing Retry count helps avoid false negatives when a window has not fully rendered yet at the moment of the check.
