Then I’m wondering: why would you want to execute something on a separate thread in the first place, if all you do is wait until it finishes and do everything possible to *not* execute your code on the thread on which you currently are!?

Yes the quote should of course read: "InvokeOnMainThread will suspend the execution of your thread, and wait for the delegate to be executed on the main thread. When that completes, the thread resumes execution." Seems this is the solution to the OP's question? Mojo can you confirm? Thanks, Chris On 06/04/12 14:17, Alan wrote: Hey, You misquoted the site. "InvokeOnMainThread" blocks execution until the delegate is invoked. *Begin*InvokeOnMainThread does not.

All locking, WaitHandles or Sleep calls can block the UI thread on iPhone and cause very weird behavior or lockups.

What you can do is: object obj = new object (); BeginInvokeOnMainThread (delegate { //Do something lock (obj) { Monitor.Notify (obj); } }); Thread.Sleep (2000); lock (obk) { Monitor.Wait (obj); } Ideally we would provide wrappers for common idioms of the .NET plataform like making the function return an IAsyncResult or Task object.

ThreadPool.QueueUserWorkItem (delegate { BeginInvokeOnMainThread (delegate { // Do something }); Thread.Sleep(2000); // Check something }); ... how can I make sure the "// Do something" is completely done before "//Check something"? In other words, how can I check when BeginInvokeOnMainThread is done and then do some stuff still in the ThreadPool.QueueUserWorkItem? Thanks!
