Temperature conversion

This was the first assignment of the semester. It was a warm up for people rusty on VB code to get familiar with programming again. It simply does a conversion from Celsius to Fahrenheit or vise versa in real time. Previously, all projects I completed had user-initiated actions by a button click or menu selection. It has a bug that crashes the program if a period is entered as the first character in the text fields even though it does a check for incorrect input.
