Workerthread in .Net 1.1

[matthias s 0]

Hello, I'm looking for a simple sample (or a utility class) on how to build a workerthread for a windows forms application in .Net 1.1. But a search on the articles didn't help really. Following I'd like to do: -> Start the App and display a Form -> Upon "start" button click start the thread (it is doing a couple of database and file operations, each of which must be completed entirely, before processing the next one) -> The thread should be able to update a progress bar on the form and a couple of labels -> When the user hits the "pause" button, the thread must complete the single operation it is currently working on and then wait until the user stops the whole thing completely or hits the "continue" button Can anyone please point me into the right direction? Thanks in advance!

I love deadlines. I like the whooshing sound they make as they fly by.

Here is an application that I made for an interview that calculates prime numbers.
