If the system has IPV6 enabled, and you are trying to pull the IP address, simply using GetHostAddresses won't work, as it will return the IPV6 address. This code should generate your IPV4 address. // using System.Net; (Required) protected string GetIPAddress() { string IPV4Address = String.Empty; foreach (IPAddress IPAddr in Dns.GetHostAddresses(HttpContext.Current.Request.UserHostAddress)) { if (IPAddr.AddressFamily.ToString() == "InterNetwork") { IPV4Address = IPAddr.ToString(); break; } } if (IPV4Address != String.Empty) return IPV4Address; foreach (IPAddress IPAddr in Dns.GetHostAddre...

Graphics cards support a variety of resolutions, refresh rates, and aspect ratios. In order to determine which display modes are available. The following function generates these display modes, and enters them into a List of type DisplayMode . List dmList = new List (); public void GetDeviceEnumeration() { foreach (DisplayMode dm in GraphicsAdapter.DefaultAdapter.SupportedDisplayModes) dmList.Add(dm); } Once the List of DisplayMode s is obtained, simply iterate through the available display modes, and populate some sort of user interface control, such as a listbox, combobox, etc, allowing users to select which resolution they want to use. The following options can be accessed through the DisplayMode: Width, Height, AspectRatio, and Format. Width: Available Screen Width. Height: Available Screen Height.
