The METER control is an ActiveX custom control that implements the functionality of an analog style "VU meter", like that found on older stereo receivers or high-end scientific instruments.

The following table documents the METER control's properties, methods, and events in an interactive manner: you can experiment with the control "live", so long as are using Internet Explorer and the control is properly installed. This page attempts to install the control; however, modern versions of Internet Explorer (quite correctly) refuse to install components of unknown origin, so your best bet is to download the control DLL and then, as Administrator, run regsvr32 METER.dll from the command console.

In any case, feel free to examine the source code of this page to learn more about the control's operation.

Please go to the bottom of the page for purchase information.
