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 and add a text file named "TextFile1.txt" to it. Add some text to the file and select it. The example displays the selected text in a message box.

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.
