How do I convert an old piece of VB6 code for VB.NET?

How would I go about converting an old piece of VB6 code for VB.NET? I was trying to use Left$ and it just started shouting at me. Thanks.
As you're finding out there are a lot of differences between VB6 and VB.NET. To be honest with you, I've found it a lot easier to rewrite the applications instead of relying on the conversion wizard.
