    <p>I'm having some issues with naudio and saving sound recordings. The code I currently have works to the point where it saves the wav file, but when I open it up, Windows Media Player returns an error: "Windows Media Player encountered a problem while playing the file"</p> <p>I have two buttons, a "Record" button, which turns into the stop button after it's pressed. And I have a "Save" button which when clicked, saves the recording to <code>sample.wav</code>.</p> <pre><code>NAudio.Wave.WaveIn sourceStream = null; NAudio.Wave.DirectSoundOut waveOut = null; NAudio.Wave.WaveFileWriter waveWriter = null; private void recordButton_Click(object sender, EventArgs e) { int deviceNumber = sourceList.SelectedItems[0].Index; sourceStream = new NAudio.Wave.WaveIn(); sourceStream.DeviceNumber = deviceNumber; sourceStream.WaveFormat = new NAudio.Wave.WaveFormat(44100, NAudio.Wave.WaveIn.GetCapabilities(deviceNumber).Channels); NAudio.Wave.WaveInProvider waveIn = new NAudio.Wave.WaveInProvider(sourceStream); waveOut = new NAudio.Wave.DirectSoundOut(); waveOut.Init(waveIn); sourceStream.StartRecording(); waveOut.Play(); recordButton.Visible = false; stopRecord.Visible = true; } private void saveResponse_Click(object sender, EventArgs e) { int deviceNumber = sourceList.SelectedItems[0].Index; string saveLocation = "c:\\wav\\sample.wav"; sourceStream = new NAudio.Wave.WaveIn(); sourceStream.DeviceNumber = deviceNumber; sourceStream.WaveFormat = new NAudio.Wave.WaveFormat(44100, NAudio.Wave.WaveIn.GetCapabilities(deviceNumber).Channels); sourceStream.DataAvailable += new EventHandler&lt;NAudio.Wave.WaveInEventArgs&gt;(sourceStream_DataAvailable); waveWriter = new NAudio.Wave.WaveFileWriter(saveLocation, sourceStream.WaveFormat); sourceStream.StartRecording(); MessageBox.Show("Recording successfully saved."); } private void sourceStream_DataAvailable(object sender, NAudio.Wave.WaveInEventArgs e) { if (waveWriter == null) return; waveWriter.WriteData(e.Buffer, 0, e.BytesRecorded); waveWriter.Flush(); } private void stopRecord_Click(object sender, EventArgs e) { if (waveOut != null) { waveOut.Stop(); waveOut.Dispose(); waveOut = null; } if (sourceStream != null) { sourceStream.StopRecording(); sourceStream.Dispose(); sourceStream = null; } if (waveWriter != null) { waveWriter.Dispose(); waveWriter = null; } recordButton.Visible = true; stopRecord.Visible = false; saveResponse.Enabled = true; } </code></pre>

    1. COCan you show the code behind your 'stop' action please? Just need to see how you're closing off the `waveWriter` and such.

    2. CO@Corey, I added the 'stop' action to the code. Cheers.

    3. COOK, tested with similar code and all seems to be working for me. Are you stopping the recording before attempting to play it in WMP?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
