In the end you will have to use some sort of threading. The way it basically works is that you start a function with a new thread and it will run until the end of the function.

If you are using Windows Forms then a nice wrapper that they have for this is call the Background Worker. It allows you to work in the background with out locking up the UI form and even provides a way to communicate with the forms and provide progress update events.
