If by stuck, you mean that your GUI stops functioning, you should consider running your parse function on a background thread. This will keep your UI functioning while your file is parsed.

Here is an article about implementing async callbacks in .Net. It's actually written in C#, but hopefully you can translate it VB.Net.
