As for the question, you will want to add a Timer to your form for that. Set its Interval property and Start it and it will raise its Tick event intermittently. You can handle the Tick event and do your work. To do different things each Tick you will need to store a state in one or more variables, e.g. a step number in an Integer that you increment each time. Start out just playing with the Timer to see what it can do. Also make sure that you read the appropriate MSDN documentation. Once you are comfortable with it, then you can bend it to your will for this specific task.
