| Windows Forms Application Version Numbers
Using the information in the AssemblyInfo class file, various information relating to a Windows Forms application can be defined, including a four-part version number. This information can be particularly helpful when multiple versions are in live usage. |
| Capturing the Screen Contents in .NET 2.0
When supporting installed software, descriptions of problems can be enhanced greatly by viewing the contents of the user's screen. In this article we will explore how to perform a screen grab and display the captured image in a Windows Forms application. |

| Standby or Hibernate Windows Programmatically
One of the features of Microsoft Windows is the ability to enter standby or hibernation power-saving states that can be resumed at a later time. Usually the system is paused using the Start menu. However, using .NET 2.0, this can be achieved in code. |
| Exiting Windows and Logging Off Programmatically
If you develop software that updates key Windows configuration settings, you may require that the system be restarted or that the users logs out and performs a new login process. Using Windows API functions, this can be controlled programmatically in C#. |
| Allowing Only One Instance of an Application
Standard Windows Forms applications can be launched multiple times and each instance used completely independently of the others. However, sometimes it is important to restrict the user in launching a single instance of a program. |
| Playing Windows System Sounds in .NET 2.0
