How to Soft Reset by VB.NET

[mohdfaisel]

Hi

I'm using Symbol PDT8100 windows mobile OS and my applications on VB.NET 2003.

Whenever I used to softboot the symtem by pressing Func+End+Light.. most of the time it is getting Hardbooted and I'm loosing all the datas.

Thatswhy I believe if reset by an application, it won't get hardbooted. Can someone help me the coding?

Thanks in advance

Yes, you must use the
KernelIoControl of coredll API
Here is an example http://www.pinvoke.net/default.aspx/...ernelIoControl
it does HARD reset, The params must be set here:

uint IOCTL_HAL_REBOOT = CTL_CODE(FILE_DEVICE_HAL, 15, METHOD_BUFFERED, FILE_ANY_ACCESS);

Also the IOCTL_HAL_REBOOT is that does all the work. Here a param of
0x00000101 is set for it (in DEVICE_HAL). Do try a 0x101003C i think it reboots but NOT 100% sure. Maybe pete can give more info...

Hi,


Try....

Shared<DllImport("Coredll.dll")>  _
Function KernelIoControl(dwIoControlCode As Integer, lpInBuf As IntPtr, nInBufSize As Integer, lpOutBuf As IntPtr, nOutBufSize As Integer, ByRef lpBytesReturned As Integer) As Integer


Shared<DllImport("Coredll.dll")>  _
Sub SetCleanRebootFlag()


Public Sub hardReset()
   Me.reset(True)
End Sub 'hardReset


Public Sub softReset()
   Me.reset(False)
End Sub 'softReset


Private Sub reset(hardReset As Boolean)
   Dim IOCTL_HAL_REBOOT As Integer = &H101003C
   Dim bytesReturned As Integer = 0
   If hardReset Then
      SetCleanRebootFlag()
   End If
   KernelIoControl(IOCTL_HAL_REBOOT, IntPtr.Zero, 0, IntPtr.Zero, 0, bytesReturned)
End Sub 'reset

very carefully

Oh. So it was 101003C
I was not sure. So if it burns your PDA or something blame it on pete,ok

[petevick]

That's why I said carefully

The code should allow for a hard reset or a soft reset.

It may be worthwhile asking for confirmation before it happens.

I would also back up, and, as usual, there are no guarantees

How to Soft Reset by VB.NET from Desktop? Is possible?

Thank you

Hi,
the only way I can think, would be to use 'RAPI' to start a program on the PPC to do a soft reset
