Am I just being crazy?Weird, I usually do something similar to live mode (start an empty row above the song and put a one phrase chain in front of the channel If the buffer size is set to 0 then it will be made large enough to contain the entire wave file, otherwise, the audio being recorded will be streamed to buffers The only thing I notice is that you're closing waveOut right away. http://techkumar.com/error-code/windows-error-codes-0x.html

uDeviceID Identifier of the waveform-audio output device to open. If fdwOpen contains the CALLBACK_FUNCTION flag, dwCallback is a pointer to a callback function. fdwOpen Flags for opening the device.

Copy public void Dispose() { Stop(); FreeWaveBuffers(); } } The SoundMessageWindow is derived from the MessageWindow class and handles the passing of the audio system messages back to the application. A block represents a buffer position in the audio file, whereas a buffer represents the physical memory allocated for loading and playing blocks. Copy public Wave.MMSYSERR Resume() { return waveOutRestart(m_hwo); } The Pause method pauses playback until Resume is called to restart it. The WaveIn class provides a method for saving the recorded blocks to a file.

You'll have to post the contents of your wfInfo struct for me to be sure... http://msdn.microsoft.com/en-us/library/aa910393.aspx basic steps: - waveOutOpen to open the audio device - waveOutPrepareHeader to "register" memory buffers (in the form of WAVEHDRs) which you'll use to output audio - waveOutWrite to output But it's a more stable emulator in general for linux users than vba.

wi.Save(fileName); The sample is provided in both C# and VB but for brevity's sake, all sample code in this document is provided in C#. his comment is here The WAVE_MAPPER constant can also be used as a device identifier. One problem though, i can't actually do this in my project because i still have to get to the data chunk, which requires passing through all the others. Perhaps that's why waveOutOpen is crashing?

Do glass window in space station/space shuttle/other space craft have practical usage? When the event is signaled, you can get the current state of the waveform buffer by checking the dwFlags member of the WAVEHDR structure. (See waveOutPrepareHeader.)

It'll start with the RIFF header then you find the 'fmt ' chunk which has the samplerate and stuff then you have the 'data' chunk which has the PCM data. Recording and Playing Sound with the Waveform Audio Interface .NET Compact Framework 1.0   Geoff Schwab Excell Data Corporation Contributions by: Seth Demsey Microsoft Corporation Jonathan Wells Microsoft Corporation January 2004 As for dumping the data, no need, i debugged the app and put a few watches on the variables. Just as a test to see if you can get audio working.

And are there any other details that I should know about the process?

I decided to stick with GDI+. Thanks. waveOutOpen function The waveOutOpen function opens the given waveform-audio output device for playback. It doesn't wait for the entire sound to play, it just starts playing it and then your program keeps running.

But my guess is either: 1) The data was being read from the file incorrectly (reading to a struct directly always makes this a possibility -- hence why I don't encourage The structure pointed to by pwfx can be extended to include type-specific information for certain data formats.
