[DotNetDevelopment] [Help]Implement vibrating function in Windows CE 5.0

[Alexander Man]

Dear all,

     I am doing an Windows CE 5.0 application project, which requires
vibrating function. I have tried three ways to implement it, but all
fails.
impl
    Here is the summary of my trials.

Project Background
OS: Windows CE 5.0
Framework version: .NET Compact Framework 2.0 SP2

Trial 1:
Using OpenNetCF community version 2.3

I  refereneced OpenNETCF.WindowsMobile to my project, and try calling
Vibrate method.
However, it failed woth the following exception message:
Can't find an Entry Point 'VibrateGetDeviceCaps' in a PInvoke DLL
'aygshell.dll'.

Here is the core code used for the trial:
using System;
...
using OpenNETCF.WindowsMobile;
...
private void btnTestVibration_Click(object sender, EventArgs e) {
    MessageBox.Show("Supported Amplitude Level(s) " +
Vibrate.GetDeviceCaps(Vibrate.VibrationCapabilities.Amplitude).ToString
());
}

Trial 2:
P/Invoke Vibrate(), VibrateGetDeviceCaps() and VibrateStop() from
aygshell.lib

Referring to the article in MSDN (http://msdn.microsoft.com/en-us/
library/ms836136.aspx), I invoked those three methods to my project.
However, it also didn't work with the following exception returned:
Can't find PInvoke DLL 'aygshell.lib'.

Ironically, the bottom part of the article stated device running
Windows CE 3.0 or above would support those functions.

Requirements

Smartphone Platforms: Smartphone 2002 and later
OS Versions: Windows CE 3.0 and later
Header: Declared in vibrate.h
Library: Use aygshell.lib
...

Here is the core code used for this trial:
using System;
...
["using OpenNETCF.WindowsMobile" is removed]
...
public class Vibrator
{
        [DllImport("aygshell.lib", EntryPoint = "Vibrate",
SetLastError = true)]
        public static extern VibrateReturnValue Vibrate(uint
numOfElements, VibrateNote[] noteArray, bool isRepeat, uint timeout);

        [DllImport("aygshell.lib", EntryPoint =
"VibrateGetDeviceCaps", SetLastError = true)]
        public static extern int GetDeviceCaps(VibrateDeviceCaps
caps);

        [DllImport("aygshell.lib", EntryPoint = "VibrateStop",
SetLastError = true)]
        public static extern int Stop();
}
    [Flags, UnmanagedName("VIBRATEDEVICECAPS")]
    public enum VibrateDeviceCaps
    {
        /// <summary>
        /// Query the amplitude that the device supports
        /// </summary>
          VDC_AMPLITUDE,
        /// <summary>
        /// Query the frequency that the device supports.
        /// </summary>
          VDC_FREQUENCY,
        /// <summary>
        /// A placeholder to indicate the last value in the list
        /// </summary>
          VDC_LAST
    }
...
public partial class Form1 : Form
{
private void btnTestVibration_Click(object sender, EventArgs e) {
    MessageBox.Show("Supported Amplitude Level(s) " +
Vibrator.GetDeviceCaps(VibrateDeviceCaps.VDC_AMPLITUDE).ToString());
}

Trial 3:
Similar to Trial 2, but I tried to invoke those from "aygshell.dll"
instead.

Still, I got the same message as the trial 1 did:
Can't find an Entry Point 'VibrateGetDeviceCaps' in a PInvoke DLL
'aygshell.dll'.

After all, I searched MSDN for "aygshell" again, and these seems no
any vibration-related functions.
(http://msdn.microsoft.com/en-us/library/ms927275.aspx).

To conclude, vibration support may not to able to be implemented from
'aygshell' library. Therefore, I came here and posted question, in
hope of getting an solution to achieve the goal.

I am glad to provide more information if needed. Many thanks.
