Call Application.Run (or even Application.DoEvents) do establish a message queue for your secondary thread.
A better answer: You should not be performing any long-blocking operations on your main UI thread. This rule goes right up there alongside "thread that creates the window services the window". (By "it is difficult to free the main thread" I assume you mean your main UI thread is performing some long-blocking operation -- like socket i/o, or calculating pi to 3000 decimal places, or what have you. Don't do that.) -Shawn http://www.windojitsu.com/ On Fri, 20 Feb 2004 13:35:57 -0500, Aman Jain <[EMAIL PROTECTED]> wrote: >Hi Everybody, > >The alarm manager in my Windows Forms application has a alarm control >(User control) that is used to display errors. >This is created on the Main thread.
