Re: Threading across abstraction layers

Why not implement a delegate/event that the main thread can implement a
handler on and have the thread raise it when it's done? Othe options would
be a Mutex or other synchronization event.

Greetings,

You can tell I am nearing the end of my project as I am
now posting all my little bugaboos that I do not have an
answer for.

I am using Merge Replication and I want to pop-up a
window with an animated GIF that executes during the span
of the call to Replicate the data.

Now since I cannot query the state of the thread in CE,
how am I going to know when the call to the Replicate
method is done?

Right now, I will be doing this sort of thing within my
presentation layer:

private void UpdateData()
{
MyDataReplicator myDataReplicator = new MyDataReplicator
();
myPopup popup = new myPopup(); // form with animated GIF
Thread thread = new Thread(new ThreadStart
(myDataReplicator.Replicate()));
thread.Start();
popup.Show();
while (true)
{
popup.Update(); // animate next frame of GIF
sleep(1000);
*** something here to check state of "thread" to see
if it has completed execution - if true, break
}
popup.Dispose();
myDataReplicator.Displose();

Also, what are the best practices for disposing of a
thread like this once it has completed?

Note that I do not want to use Invoke to update my GUI
from the delegate thread as it is in my Data Tier and
making such a callback would really muck up my
abstraction model.

Cheers, Ian Williamson
