In this example we declare one HtmlInputText controls, one HtmlInputButton control, and one HtmlGeneric control in an .aspx file (remember to embed the controls inside an HtmlForm control). When the submit button is triggered, the submit subroutine is executed. The submit subroutine writes a welcome message to the p element.
