重新啟動WinCE系統

WinCE系統若想要重新啟動，沒有.NET的Managed函數可用，須倚靠 Coredll.dll的KernelIoControl完成，以下是用Managed包裝後的重啟函數，使用方法很簡單，直接呼叫ResetSystem()即可：

Private Const FILE_DEVICE_HAL As Integer = &H101

Private Const METHOD_BUFFERED As Integer = 0
Private Const FILE_ANY_ACCESS As Integer = 0


Private Function CTL_CODE( _
  ByVal DeviceType As Integer, _
  ByVal Func As Integer, _
  ByVal Method As Integer, _
  ByVal Access As Integer) As Integer


    Return (DeviceType << 16) Or (Access << 14) Or (Func << 2) Or Method


End Function 


Declare Function KernelIoControl Lib "CoreDll.dll" _
    (ByVal dwIoControlCode As Integer, _
     ByVal lpInBuf As IntPtr, _
     ByVal nInBufSize As Integer, _
     ByVal lpOutBuf As IntPtr, _

     ByVal nOutBufSize As Integer, _
     ByRef lpBytesReturned As Integer _
    ) As Integer


Private Function ResetSystem() As Integer

    Dim bytesReturned As Integer = 0
    Dim IOCTL_HAL_REBOOT As Integer = CTL_CODE(FILE_DEVICE_HAL, _
      15, METHOD_BUFFERED, FILE_ANY_ACCESS)

    Return KernelIoControl(IOCTL_HAL_REBOOT, IntPtr.Zero, 0, _

      IntPtr.Zero, 0, bytesReturned)
End Function
