* ==== == ======
|
||
|
|
* 07/16/99 rodtoll Created
|
||
|
|
* 07/30/99 rodtoll Updated to allow creation of object using a pre-created
|
||
|
|
* DirectSoundCapture Object.
|
||
|
|
* 08/04/99 rodtoll Added member to retrieve DSC object
|
||
|
|
* 11/12/99 rodtoll Modified abstraction for new waveIN support.
|
||
|
|
* Now abstracted types look almost like dsoundcap objects
|
||
|
|
* 11/22/99 rodtoll Added code to map from GUID to waveIN device
|
||
|
|
* ID for non-millenium systems.
|
||
|
|
* 11/23/99 rodtoll Updated to use waveIn device ID or DSound 7.1 when they are avail
|
||
|
|
* 12/01/99 rodtoll Bug #115783 - Will always adjust volume of default device
|
||
|
|
* Now uses new CMixerLine class for adjusting volumes/selecting mic
|
||
|
|
* rodtoll New algorithm to map from GUIDs to device IDs if DSound 7.1 is not
|
||
|
|
* available. Will map device correctly on DX7, will guess for other
|
||
|
|
* DX versions < 7. However, default device is assumed to be waveIN ID #0.
|
||
|
|
* 12/01/99 rodtoll Bug #115783 - Will always adjust volume of default device
|
||
|
|
* Now uses new CMixerLine class for adjusting volumes/selecting mic
|
||
|
|
* 12/08/99 rodtoll Bug #121054 - DirectX 7.1 support.
|
||
|
|
* - Added hwndOwner param for capture focus support
