|
* ==== == ======
|
||
|
|
* 11/04/99 rodtoll Created
|
||
|
|
* 11/22/99 rodtoll Added code to allow specification of wave device ID
|
||
|
|
* 11/23/99 rodtoll Updated to use waveIn device ID or DSound 7.1 when they are avail
|
||
|
|
* rodtoll Added SelectMicrophone call to the interface
|
||
|
|
* 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
|
||
|
|
* - Added lpfLostFocus param to GetCurrentPosition so upper
|
||
|
|
* layers can detect lost focus.
|
||
|
|
* 01/28/2000 rodtoll Bug #130465: Record Mute/Unmute must call YieldFocus() / ClaimFocus()
