| |  Recording at stream
Hi
i want to record voice and send it throw Bluetooth stream , the problem is the recorder accepts only I.O Stream
And write at the 'stream' without using (stream.write), -
''using openNETCF
-
Dim Stream1 As Stream
-
Stream1 = File.OpenWrite("\My Documents\" & txtFileName.Text & ".wav")
-
m_Recorder = New OpenNETCF.Media.WaveAudio.Recorder
-
m_Recorder.RecordFor(Stream1, 5400,OpenNETCF.Media.WaveAudio.SoundFormats.Stereo16bit11kHz) '' accept only i.o stream and record into it
-
The Bluetooth stream I could write byte -
''using InTheHand 32feet.NET
-
dim Buffer1 As Byte
-
Dim stream As System.IO.Stream = Nothing
-
stream = client.GetStream() '' return i.o stream
-
stream.Write(Buffer1, 0, BufferLen)
-
How to connected them so I could record and write at the same time (could I use memorystream)
Thanks

Thanks | Have you tried -
m_Recorder.RecordFor(client.GetStream(), 5400,OpenNETCF.Media.WaveAudio.SoundFormats.Stereo16bit11kHz)
Just replace the file writer stream with the IO stream. Wouldn't that work?

wait if Client.GetStream() returns an IO stream and OpenNETCF.Media.WaveAudio.Recorder.RecordFor(...) takes and IO stream as it's first argument then what is the problem?
Do you have some documentation for the openNETCF package?

Nevermind I found it. client.GetStream() returns a type of NetworkStream which is a type of IO stream but I think you should try explicitly casting it as an IO stream.
