Are you actually wanting to post a message to the message loop or are you simply wanting to update some control in your Form, display a message box, etc.? If it's the former, then refer to @Noldorin's response. If it's the latter, then you need to use the Control.Invoke() method to marshal the call from your "reading" thread to the main UI thread. This is because controls can only be updated by the thread they were created on.

This is a pretty standard thing in .NET. Refer to these MSDN articles to get the basics:

• Control.Invoke Method
• Control.InvokeRequired Property (refer to first example in Community Content)

Once you understand how to do this, refer Peter Duniho's blog for how to improve on the canonical technique.
