This article demonstrates the use of an active Gauge in a Visual WebGui application.

'VB.NET Code

// C# Code

The application contains a PictureBox (to show the gauge), a TextBox (to show the current numeric value) and a ProgressBar (to allow changing the value on a scale). Changing the value to be displayed by the gauge by either the ProgressBar or the TextBox causes a new gauge image to be generated on server-side with the new value - sent from the client. This image is then established as the resource of the PictureBox via a Visual WebGui Gateway. The end result is that the PictureBox displays the new image on the client.
