OnWaveformAnalyzerHorzLineReached event |
|
Remarks
Occurs when the playback position reaches a graphic item of type "horizontal line" inside the waveform analyzer.
This event replaces the usage of the CallbackWaveformAnalyzerHorzLineReached 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_WAVE_HORZ_LINE_REACHED.
For details about graphic items management on the waveform analyzer refer to the How to add graphic items to the Waveform analyzer section.
For details about the use of the Waveform Analyzer refer to the How to use the Waveform Analyzer section.
For further details about methods of the Waveform Analyzer refer to the WaveformAnalyzer class section.
