Thread Suspend and Resume

Having not used threads for such a long time in vb.net I have found myself
in need of them

I have a thread that runs and retirieves live data from a SQL database, this
is running fine and has been doing its job for a long time

the problem is I need to suspend this thread when a checkbox is clicked (as
the data is no longer required) but when the checkbox is unclicked it needs
to restart

simple enough i thought Suspend/Resume exist, problem is as im sure your
aware, these appear to be on the way out (and will be removed completely
from the next version of the .net framework!!)

how do i now suspend/restart a thread without using defunct code???

ive searched the web for this and everything still points to suspend/resume,
which is of little help to me

thanks in advance

Simplest way is setting a boolean flag to have a Thread wait for something.
Then use an event (for example AutoResetEvent) set from outside to let the
Thread continue.

Suppose a function which has Sleep() method in it. And I want to recycle it. I made two buttons which call "Resume()" and "Suspend()". But It doesn't work. The state of thread "t" will be "WaitSleepJoin" when it runs because the function it calls - "GenerateEvents()" has "Sleep()" function. Can I solve this problem with Thread? I don't...

My first thought was to call WorkerThread.Suspend but the help cautions against this (for good reason) because the caller has no control over where the thread actually stops, and it might have a lock pending, for example. I want to be able to stop a thread temporarily, and then optionally resume it or stop it for good.

At the same time the thread is suspended. When I try to resume it from the another function I have some problems. Thank you. Juky

Hello, I want to understand whats the best way to write code to replace Thread.Suspend, Thread.Resume and Thread.Abort.

I have a code which registers all threads with a thread dump class. At intervals this thread dump class will dump the stack trace of all threads. As calling StackTrace(threadtoDump) from a different thread other than the treadToDump the threadToDump must be suspended otherwise a ThreadStateException gets thrown. However under .NET 2.0...
