When I started using code, I was mostly self-taught (with the help of Google). I would want to do something and search the web for a solution and use code other people posted. Once you get some basic familiarity with the event handlers and the concept of a module, it is not as intimidating. Soon enough, I started to recognize the logic was able to write simple code on my own.
When that wasn't enough, I took a vb class at my local community college. I wouldn't recommend the book we used in class (it was ok) but if you do an Amazon search I am sure you can find something great. I would highly recommend taking a class, however, if you find you are not a natural at this. You can learn much more from someone who is an expert than you can on your own with only a book and the web as a guide.
