System Inactive

Hi all,

I eventually worked out a way of achieving this; there is an API call which can be used:

[DllImport("User32.dll")]
private static extern bool GetLastInputInfo(ref LASTINPUTINFO plii);
[DllImport("Kernel32.dll")]
private static extern uint GetTickCount();

internal struct LASTINPUTINFO
{
public uint cbSize;
public uint dwTime;
}

private uint GetIdleTime()
{
LASTINPUTINFO lastInPut = new LASTINPUTINFO();
lastInPut.cbSize = (uint)Marshal.SizeOf(lastInPut);
return GetTickCount() - lastInPut.dwTime;
}

Many thanks,
Lea Hayes
