Voice Recorder For Pocket PC (VB.NET version)

Okay we have here a VB.NET version of the .net compact framework voice
recorder sample that uses open net CF
c# version at:
http://www.opennetcf.org/forums/topic.asp?TOPIC_ID=79

THIS CODE CREATES AN INSTANCE OF A VOICE RECORDER, but now how do you
get it to record, save, play back, etc?

' NOTES

------------------------------------------------------------------------

' Q: Once we have a voice recorder object, how do you then pass messages
to it??
' A: Im working on that... Essentially the sendmessage api function will
need to
' be p/invoked. The voicerecordercr eate function has returned the hwnd
so
' messages can be sent to this. The voice recorder messages are
documented in
' the sdk
' I haven't had much luck with the sendmessage function - everytime I
try to
' send a message to the voicerecorder, it just closes the
voicerecorder.. ...
'
' I got this code to run. This code seems to record to files in \\My
' Documents\~VRec _* where * is a number.
' Alan, did you install the Speech.NET or Speech API?
'
' The files ~VRec_* are temporary files that the voice recorder uses to
store
' the data while it is recording. Sometimes, depending on how the
recorder is
' terminated, they get converted to recording*.wav
'
' Take a look here:
' http://www.innovativedss.com/forums/...sp?TOPIC_ID=80
' for an example of playing .WAV sounds.

' Tom Shelton (to*@YOUKNOWTHE DRILLmtogden.co m)
' 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#.
