//----------------------------------------------------------------------------- // // Sample Name: PlaySound Sample // // Copyright (c) Microsoft Corporation. All rights reserved. // //----------------------------------------------------------------------------- Description =========== The PlaySound sample shows how to play a wave file in a DirectSound secondary buffer. Path ==== Source: DXSDK\Samples\C++\DirectSound\PlaySound Executable: DXSDK\Samples\C++\DirectSound\Bin User's Guide ============ Load a wave file by clicking Sound File. Select Loop Sound if you want it to play repeatedly. Click Play. Programming Notes ================= The basic tasks write an application that supports DirectSound are as follows: * Set up DirectSound: 1. Call DirectSoundCreate to create a IDirectSound object 2. Call IDirectSound::SetCooperativeLevel to set the cooperative level. 3. Set the primary buffer format. This sample calls DSUtil_SetPrimaryBufferFormat() to do just this. * Load a wav file into a DirectSound buffer: 1. Read the wav file to get the wav file size, and the wav format in the format a WAVEFORMATEX structure. 2. If the wav file of reasonable size, then create a DirectSound buffer big enough to hold the entire wav file, and set it's format to that of the wav file. If the wav file large, then see the StreamData sample for information on how to stream data into a DirectSound buffer. 3. Next, fill the DirectSound buffer with wav data. A pointer into the buffer can be obtained by calling IDirectSoundBuffer::Lock. After the memory has been copied, call IDirectSoundBuffer::Unlock. * Play or stop the DirectSound buffer: 1. First, check to see if the buffer was not lost. If it was, then it will need to be restored. 2. To play the buffer call IDirectSoundBuffer::Play. 3. To stop the buffer call IDirectSoundBuffer::Stop. * To check to see if the sound stopped: It may be useful to tell if a DirectSound buffer stopped playing. An easy way to do this would be to set a timer to trigger every so often. When the timer message is sent, call IDirectSoundBuffer::GetStatus to see if the DSBSTATUS_PLAYING is set. If it is not, then the sound has stopped. * Handle restoring a DirectSound buffer: First call IDirectSoundBuffer::Restore. Next, fill the buffer with sound again since the sound data was lost from when the buffer was lost. * Free DirectSound: Simply call Release() on all the DirectSound objects that were created.
