Recently I’ve been playing around with a webbrowser control to automate my interaction with a website for testing purposes. I am using C# and DOT NET.

I found it a bit difficult to change the value of an HTML combobox (i.e. dropdown), but as it turns out it’s rather easy.I used the following code to change the value of a combobox named: “test” to the value 12.

This code was used for the following HTML:

Finally the following code was required to press the “Submit” button.

I recently wanted to get the usage of my CPU in C#. After searching the internet I found a way of doing it using the PerfomanceCounter class. I made a couple of changes and I created the following class, which seems to work.

Using the statement: SystemUtils.getCpuUsage() you should be able to get an integer number showing the CPU usage.
