Calculator

[EDN Admin]

I have a basic calculator buttons btn0 through btn9 and hexA-HexF and a label to hold the numbers. Group box with choices hexdecimal , decimal, octal, and binary. what I need is the code for hexdecimal and octal and binary. could someone please help to
provide the code for each. everything happens under the Equals button.hereis the code so far.
