COM Objects > VUMeter object > Methods

Remarks

Creates the VU-Meter object: once created, the VU-Meter will stay active until the termination of the container application: being a graphical object, the VU-Meter needs to be associated to an existing window that will be used as a surface for the graphic rendering: this window can be changed at a later time through the VUMeter.SetHwnd method.

Once created, by default the VU-Meter is still not visible: you must make a call to the VUMeter.Show method in order to display it.

For further details about using the embedded VU-Meter refer to the VUMeter object section.

For details about using Visual Feedbacks refer to the How to use embedded Visual Feedbacks section.
