Events for Visual Basic 6 COM interoperability > OnSoundPlaybackStatusChanged event

Remarks

Occurs whenever the status of a playback session changes.

This event replaces the usage of the CallbackSoundPlaybackStatusChanged delegate and is only intended for usage with applications developed using Visual Basic 6 (which results unreliable when dealing with delegates and callbacks) and, in order to be enabled, requires a call to the COMEventEnable method with the nEventType parameter set to EVENT_TYPE_REC_SOUND_STATUS_CHANGED.

Syntax

[Visual Basic 6]

Private Sub RecorderApi_OnSoundPlaybackStatusChanged ( _

ByVal nStatus As enumPlaybackStatus _

)

where "RecorderApi" is declared in Visual Basic 6 code as:

Dim WithEvents RecorderApi As AudioSoundRecorderApi.AudioSoundRecorderApiObj
