I need a small program which will detect if any key from A to Z or 0 to 9 is pressed than it makes a txt file, after that if nothing happend for 30 minutes it delete that file and it should work as process.
And there is config file to set PATH and time.
I get this in C# but it doesn't work, can someone look at it and see why it is not working, please?
here is C# version

Code: [SELECT]using System.Runtime.InteropServices;
using System.Threading.Tasks;



[DllImport("user32.dll")]
static extern bool GetLastInputInfo(ref LASTINPUTINFO plii);

[StructLayout(LayoutKind.Sequential)]
struct LASTINPUTINFO
{
PUBLIC static readonly int SizeOf = Marshal.SizeOf(typeof(LASTINPUTINFO));

[MarshalAs(UnmanagedType.U4)]
public UInt32 cbSize;
[MarshalAs(UnmanagedType.U4)]
public UInt32 dwTime;
}

static uint GetLastInputTime()
{
uint idleTime = 0;
LASTINPUTINFO lastInputInfo = new LASTINPUTINFO();
lastInputInfo.cbSize = (uint)Marshal.SizeOf(lastInputInfo);
lastInputInfo.dwTime = 0;

uint envTicks = (uint)Environment.TickCount;

if (GetLastInputInfo(ref lastInputInfo))
{
uint lastInputTick = lastInputInfo.dwTime;
idleTime = envTicks - lastInputTick;
}

return ((idleTime > 0) ? (idleTime / 1000) : 0);
}

private uint _lastInputTime;
private bool _idle = false;
private string _fileName;
private int _idleTime = 1800;

void Main()
{
VAR cfg = File.ReadAllLines("nastavitve.cfg");
_fileName = cfg[0];
int.TryParse(cfg[1], out _idleTime);

_lastInputTime = GetLastInputTime();

while (true)
{
var inputTime = GetLastInputTime();

if (_idle && inputTime - _lastInputTime < 1)
{
_idle = false;

File.Create(_fileName).Close();
}

if (!_idle && inputTime - _lastInputTime > 5)
{
_idle = true;

if (File.Exists(_fileName))
File.Delete(_fileName);
}

Thread.Sleep(1000);
}
}

and here is version for compiling with VS
