Off the top of my head... I'm not sure why the original code is using
unsafe code. There doesn't seem to be anything used that would require that
- but, I don't know much about the Pocket PC environment. If the unsafe is
required for some reason on PPC, then you have to use C#.

Imports System
Imports System.Data
Imports System.Runtime.InteropServices

Public Class VoiceRecorder
<StructLayout(LayoutKind.Sequential)> _
Protected Structure CM_VOICE_RECORDER
Public cb As Intger
Public dwStyle As Integer
Public xPos As Integer
Public yPos As Integer
Public hwndParent As IntPtr
Public id As Integer
Public lpszRecordFileName As String
End Structure

<DllImport("voicectl.dll", CallingConvention=CallingConvention.Cdecl)>
Private Shared Function VoiceRecorder_Create _
(ByRef CM_VOICE_RECORDER voicerec) As IntPtr
End Function

Private voicerec As CM_VOICE_RECORDER
Private handle As IntPtr

Public Sub New()
With voicerec
.cb = Marshal.SizeOf(voicerec);
.lpszRecordFileName = "\My Documents\VoiceControl.wav"
.xPos = -1
.yPos = -1
End With
End Sub

Public Sub Show()
handle = VoiceRecorder_Create(voicerec)
End Sub
End Class
