How to notifiy the creator of an object of an event

[Guest]

I have multiple instances of frmDevice forms that were created by a single
frmMain. I'd like alert frmMain of certain frmDevice events.
What is the best way of doing this?
Should I create an event delegate? If so, then it seems that I would need to
pass a reference to frmMain to each frmDevice, so that I can attach a frmMain
handler.
I'm somewhat new at this, so would appreciate the help,
Thanks in advance,
Dennis

It sounds like you could use an events tutorial:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vcwlkeventstutorial.asp

It seems that frmDevice should contain an event. The delegate for this event
will look something like this...

public delegate void MyDeviceEventHandler( frmDevice sender, DeviceEventArgs
e );

When frmMain creates a frmDevice, it attaches a handler to the frmDevice's
event. You only need to have the sender in the signature of the delegate if
you care where the event comes from.
