Examples
This example uses an add-in to connect WindowVisibilityEvents. Replace the code in Connect.vb or Connect.cs file with the example code below. Run this add-in and open and close the Command Window and the Output Window in the Visual Studio IDE to see event capturing methods in action. For more information on how to run the automation examples, see How to: Compile and Run the Automation Object Model Code Examples.
