Events for Visual Basic 6 COM interoperability

Remarks

Occurs when a mouse action happens over the waveform scroller.

This event replaces the usage of the CallbackForYoutubeEvents delegate 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_YOUTUBE.

For further details about callback delegates see the How to synchronize the container application with the API tutorial.

For details about management of Youtube connections refer to How to enumerate and download video/audio clips from Youtube tutorial.
