Examples

HTMLSelect
In this example we declare an HtmlImage and an HTMLSelect control in an .aspx file (remember to embed the controls inside an HtmlForm control). Then we modify the src property of the HtmlImage control based on user choices. The value selected in the HtmlSelect control determines which image to display.

WAPT is a load, stress and performance testing tool for websites and web-based applications. In contrast to "800-pound gorilla" load testing tools, it is designed to minimize the learning curve and give you an ability to create a heavy load from a regular workstation. WAPT is able to generate up to 3000 simultaneously acting virtual users using standard hardware configuration. Virtual users in each profile are fully customizable. Basic and NTLM authentication methods are supported. Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process.
