Classes > VUMeter class > Methods > VUMeter.Create method

Remarks

Creates an instance of the VUMeter class: 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. For development environments like WPF, where controls don't expose a HWND, the usage of the VUMeter.CreateNew method should be preferred.

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 class section.

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