Based on the above details, we can write a simple line of code, which will search through all the descendants of the root element, for a UI element that has the name equals to 'Notepad':.

For this simple implementation, I used the base class AutomationElement , which, as I said earlier, keeps the reference to a UI element from desktop applications.

The idea is that we need to start from the desktop element, which is the root element, AutomationElement. After getting a valid reference to the AutomationElement of the test application, we can then interact with the different contained controls.

In this way, the controller application sets some values to two TextBox controls. As you can see in the above code, we are using a control pattern, ValuePattern. Control patterns define the specific functionality that is available in a control by providing methods, events, and properties. The methods declared in a control pattern allow the UIA clients to manipulate the control, for example, the ValuePattern.

SetValue method. Besides ValuePattern which represents a control that stores a string value, as a different example of control pattern, we can take the Invoke pattern control, InvokePattern , which represents the controls that are invokable, controls like buttons. In order to use a control pattern, we need to query the object to see what interfaces are supported, and only after getting a valid control pattern can we interact with it by using its methods, events, and properties.
