start with a simple feet/meters convertor
create a new form, then create 2 text boxes and a button onto it
the idea is to input text into textbox0 and get the answer in textbox1 by clicking the button
use the On Click event of the button to create an Event Procedure and input some code
in the module type in: Text1 = 0.3048 * Text0
Text1 being the name of the 2nd text box and Text0 being the name of the 1st text box
