Events for Visual Basic 6 COM interoperability

Remarks

Notifies the container application about the percentage of advancement of lengthy operations like loading, exporting, waveform analysis, etc.

This event replaces the usage of the CallbackPercentage 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_EDT_PERC.
