Enables you to verify if a UI element exists, even if it is not visible.
- Exists - Indicates if the element exists or not. The field supports only Boolean variables.
- Private - If selected, the values of variables and arguments are no longer logged at Verbose level.
- Target.Selector - Text property used to find a particular UI element when the activity is executed. It is actually a XML fragment specifying attributes of the GUI element you are looking for and of some of its parents.
- Target.TimeoutMS - Specifies the amount of time (in milliseconds) to wait for the activity to run before the
SelectorNotFoundExceptionerror is thrown. The default value is 30000 milliseconds (30 seconds).
- Target.WaitForReady - Before performing the actions, wait for the target to become ready. The following options are available:
- None - Does not wait for anything except the target UI element to exist before executing the action. For example, you can use this option if you want to retrieve just text from a web page or click a particular button, without having to wait for all UI elements to load. Note that this may have unwanted consequences if the button relies on elements that are not yet loaded, such as scripts.
- Interactive/Complete - Waits all of the UI elements in the target app to exist before actually executing the action.
To assess if an application is in the Interactive or Complete state, the following tags are verified:
- Desktop applications - A
wm_nullmessage is sent to check the existence of the
<uia>tags. If they exist, the activity is executed.
- Web applications:
a. Internet Explorer - The
<webctrl>tag is used to check if the Ready state of the HTML document is set to Complete. Additionally, the Busy state has to be set to "False".
b. Others - The
<webctrl>tag is used to check if the Ready state of the HTML document is Complete.
- SAP applications - First the presence of the
<wnd>tag verified, after which a SAP specific API is used to detect if the session is busy or not.
- Target.Element - Use the UiElement variable returned by another activity. This property cannot be used alongside the Selector property. This field supports only UiElement variables.
- Target.ClippingRegion - Defines the clipping rectangle, in pixels, relative to the UiElement, in the following directions: left, top, right, bottom. It supports both positive and negative numbers.
- DisplayName - The display name of the activity.
Here you can see how the Element Exists activity is used in an example that incorporates multiple activities.
