how to stop an running function or subject.
I have written an subject which when executed takes some time to finish. i have also placed an cancel button to cancel the executed of the subject.
So i wanted to know how to cancel the execution of the subject in the middle and release the resources used.
Your use of the term "subject" is incorrect. Presumably you are talking about a Sub (Sub Procedure). The name "Sub" is short for subroutine, not subject. A Sub is a method that doesn't return a value, while a Function is a method that does return a value.
While it's not impossible to do what you're asking for in a single thread, it's really not a good idea to do so. I would suggest executing your method in a background thread. If you use a BackgroundWorker to do so then the cancellation mechanism is built in. Follow the BackgroundWorker link in my signature for an example. The example you need is in post #19.
Just note that you can only cancel the background operation at certain points. You cannot stop it during a synchronous method call. You can only cancel the operation at places where you can specifically place code to do so.
Ok! I will give it a try
Thanks!

Subroutine not subject :)
