How do I do a SendMessage like operation in C#

[chris.dannemiller]

In VC++ When I wanted to send a message to a window from a worker
thread I would use SendMessage. Events only work Semi-well in C#
becuase certain GUI operations require they run in the same thread that
the window exists in. Such as displaying a balloon on the tray. Does
anyone know a good way to do this?

In order to make a call to the thread that the UI is running on, you can
call the Invoke method on a control that was created on that thread. This
will allow you to pass a delegate that will get invoked on the UI thread, as
well as the parameters to pass to it.

Hope this helps.

Hi,

I've actually written an article about this a while back. http://www.lowendahl.net/content.asp...pContent=csa31
It shows a pattern you can use to ensure that your events execute on the
correct thread.
