Detect if the current process is in a Terminal Services Client
Finally a real code example:

Use this code to detect if the process "If the calling process is associated with a Terminal Services client session".

[System.Runtime.InteropServices.DllImport("user32.dll",EntryPoint="GetSystemMetrics")]

private static extern int GetSystemMetrics(int valor);

private const int SM_REMOTESESSION = 0x1000;

public static bool IsInTerminalServicesClient() {

    return GetSystemMetrics(SM_REMOTESESSION) != 0;

}

You call IsInTerminalServicesClient() to determine if you are in a Terminal Services session. You can use this to reduce graphic input, or allow multiple instances of the application etc.
