Property Value

Type: System.Boolean

Examples

This example creates a new solution folder and adds a project to it from an existing file. It also adds a new nested solution folder to the first one, by using the AddSolutionFolder method and then displays the Hidden property and sets it to false. Before running this example, create a "Projects" folder off your main drive ("C:" in this example), and create a Visual C# class library project named "ClassLibrary1" in that folder. Open a project in the Visual Studio integrated development environment (IDE) before running this add-in.

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.
