How can a thread communicate with the main thread?

I'm a newer in CF developing, now i'm confused about the multiplethread
programing. I Created a thread to monitor the powerOff keyEvent, and
inform the Mainthread if the event comes. but it does not work when i
use interface invoke.
so i want to know how can the moniter thread communicate with main
thread.
 
There are many ways to communicate (global variables, events, both OS and
window). I don't understand what you're saying was the problem. You have
to Control.Invoke() to call a UI method from a non-UI thread, but that's no
big deal.

Hi,

I suppose you use CF1.0 and Invoke can't have parameters. A good way to
communicate is to use the MessageQueue of Win CE, to import the
functions CreateMsgQueue... there is a lot of examples of importations
of this functions on the Internet.

You can also use properties of the form as 'parameters', as long as only one
thread accesses them at a time, you don't even have to synchronize.
