Change Process Name

Is it possible to change the name of your VB.Net process (The thing you see in process list of Task Manager)?

I need it to make it change when the user interacts with a button.

That's not entirely possible as the processname is "read only"
However if you change the exe's name the process name changes.
Also, just change the text of the form as the text is what shows up under "Applications" on task manager.
