how to get a file's associated icon

I looked all over the internet, and all I could find was that it is possible, but I couldn't figure out how to do it. I need to figure out how to get the icon associated with a file type in windows, and display that icon in a picture box. I think you have to use an API call for this.
thanks for any help
