Wasn't as bad as I though it would be. I didnt try to make a GUI at all so don't hate on it. I simply did the program. It uses two functions. One to convert to Pig-Latin and another to convert to English.

Edit: Did it in C# as well for the heck of it.

I am good at VB, I just never focused on arrays. Promise you that, you know when pros can do such hard things and cant do the easy? Yes thats me.

You should brush up on arrays then. They are actually quite handy. Also, you didn't use any functions in yours. Thought I'd point that out. Your submission wasn't too bad though. Good job.
In yours, look at how it translates: chinese

Seems pretty easy to do, well in java anyway.

Give it a shot
