How to add items to window control menu?

[weballegry]

Hello,

I have the following task:

1.Add new menu item to window control menu (the one that opens with right click when clicking the window caption bar, it contains move,restore,minimize,maximize,close etc).

2.Whenever the new item clicked there is another application which needs to be notified about
this event.

So I need to know with what win api to add the item and how do I implement the said communication between applications.

I develope with .net C#, using imports of winapi functions.

It depends on remote application. Generally, any IPC would do.
