NRadialGaugeIndicatorsUC.     WinForms App - using Visual Studio.

I want to use the above component in my application. I have the examples solution part of the .NET vision which provides the code however that code seems to long just to display the indicator.

my question is I want to update the indicator every 5 secs with a new reading. the reading will be read from a sql datasource - is this possible and how to do this without using all this code below?

thanks
