Examples

This example makes a text file the active window. It then uses it to iterate through the windows collection and to display the name of the containing project and project item for the window.

Before running this example, open a project in Visual Studio, add a text file named "TextFile1.txt" to it, and make it the active window.

For more information about how to run this example as an add-in, see How to: Compile and Run the Automation Object Model Code Examples.
