Sample Code:

[DllImport("kernel32.dll")]

public static extern IntPtr CreateWaitableTimer(IntPtr lpTimerAttributes,

bool bManualReset, string lpTimerName);

[DllImport("kernel32.dll")]

public static extern bool SetWaitableTimer(IntPtr hTimer, In ref long

pDueTime, int lPeriod, TimerAPCProc pfnCompletionRoutine, IntPtr

lpArgToCompletionRoutine, bool fResume);

[DllImport("kernel32", SetLastError = true, ExactSpelling = true)]

public static extern Int32 WaitForSingleObject(IntPtr handle, Int32

milliseconds);

public static uint INFINITE = 0xFFFFFFFF;

The main code is :

private IntPtr handle;

private void shutdownToolStripMenuItem_Click(object sender, EventArgs e)

{

DateTime dt = DateTime.Now;

dt.AddSeconds(30.0);

long duetime = dt.ToFileTime();

handle = Win32.PowerManagement.CreateWaitableTimer(IntPtr.Z ero, true, "");

Win32.PowerManagement.SetWaitableTimer(handle, ref duetime, 0, null,

IntPtr.Zero, true);

Thread t = new Thread(new ThreadStart(this.NewThread));

t.Start();

}

private void NewThread()

{

int ret = Win32.PowerManagement.WaitForSingleObject(handle,

(int)Win32.PowerManagement.INFINITE);

MessageBox.Show("Wait object"); // ret = 0x00000000L here

}
