UI Automation simple provider sample
This sample application creates a simple custom control that implements Microsoft UI Automation provider interfaces. By implementing these interfaces, assistive technologies such as screen readers can programmatically access information about the control and make the control accessible to users with disabilities.
The control is a simple custom button that supports the Invoke control pattern. Clicking the button causes it to change color. You can also tab to the button and click it by pressing the spacebar.
To test the functionality of the Invoke control pattern, you can use Inspect (an accessibility testing tool available from the Windows Software Development Kit (SDK).
Warning This sample requires Microsoft Visual Studio 2013 or a later version (any SKU) and will not compile in Microsoft Visual Studio Express 2013 for Windows.
