I am trying to make a program on Visual Basics that lets me basically type a message in a text box for example (Hello, How are you doing) and make it come out on Texbox 2 when i click (encrypt) saying (QREEO, QOE XFR KOB FOJNG).. Or if i typed (QREEO, QOE XFR KOB FOJNG) and i click (decrypt) have it come out textbox 2 saying (Hello, How are you doing). Now obvisuly i dont care about case-sensitivity but I do want to be able to code the program so that it know my (secret language) and can translate something back to me if I want it to.. I was thinking I could like code the buttons to have the textbox like say (if textbox1 = "A" then textbox2 = "R" ... something like that I have like really little expierence coding but i do know how to use the program. So I know its alot but code someone at least get me started on what the coding would even be or some suggestions... (Its not all random its an actual code that i put together...)
