Hi,
Im running a timer to Unzip a zip file using a 'ICSharpCode.Sh arpZipLib.dll'.
It works well when I block the main thread indefinitely by 'thread.sleep(-1)'.
But gets an ThreadAbort Exception if i run the timer without thread blocking.
How can i avoid this error?Im not using thread.abort anywhere in my
code.My code to unzip file is taking only 6 sec to complete.
Below im showing the code. -
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
-
fnInitiateZipTimer()

Thread.Sleep(-1)

I use the Suspend() and Abort() methods based on button events.
I can watch the progress meter increase just fine when the thread is

Hi
I wrote an application server (a remoting sinlgeton), where processes must
be stopped in very rare cases, done thru a Thread.Abort(). Occasionally, and
only after a Thread.Abort(), this component becomes instabile, throwing a
Windows like error (access violation on 0x00000002), not an framework
exception. The component and all of its subcomponents are 100% managed code.
What could go wrong with Thread.Abort()?
Thanks for any hints.

I read from a serialport using a worker thread. Because the worker thread t
does not loop often, I cannot wait to terminate the worker thread using a
boolean in the While condition.
So I have a StopReader() method that simply aborts the worker thread (is
there a better way for the above situation?).
The StopReader creates an ObjectDisposedException when calling t.Abort(). WHY?

When I do this, I put a special value in the queue (like None) and in

Threads can also be marked as "daemon threads" (see docs for
threading.Thread objects). This will make the application terminate if
only "daemon threads" are left.
