Custom close dialog menu buttons

As you are undoubtedly aware any windows form in the topmost area when right clicking on it will bring up the following menu.

|  Restore |
|   Move   |
|   Size   |
| Minimize |
| Maximize |
|----------|
|  Close   |

Unfortunately I have no idea what this menu is called and could probably google an answer if I did but either way I have seen applications that have added custom functionality of their own in this area. How would that be accomplished?

I am assuming a registry ent开发者_如何学Pythonry somewhere? Lastly is there some way of passing in the name of the calling process when your custom button is clicked?

It is called 'System Menu' and it can be customized. See this example. Another and maybe easier to understand example here at Codeguru.com.

In this case I assumed you're using .NET. Can you confirm this?
