Make a program to convert a number to decimal, octal, hexadecimal and binary value

Hi guys, i really need your help with my project:

I need a program that convert a number to decimal, binary, hexadecimal or octal value.

I'am working on GUI and i have on my GUIDE the next things:

2 popupmenu

2 edittext

Well, i was thinking i could do a simple conversor (like google conversor).

And the edittext1 i enter the number to convert, then i choosee on the popupmenu1 what value is it(it can be decimal, binary, hexadecimal or octal value)

after that, i choose on the popupmenu2 what value i wanna convert and that value will be set on the edittext2.

I'am a beginner here,guys i hope you can help me with the code, please, help me with a code with the native variables(like edittext, popupmenu, etc).

Thanks ☺

I've attached a pic of my GUI.

Thanks Mr Freschi.

But can you help me with the code please?

I don't know how to do that conversor, i'am new here.

[Fabio Freschi]

once you get the number from the text box, check the values of the pulldown menus, then use a multiple if-statement

if (fromFormat == 'binary') && (toFormat == 'decimal')
    output = bin2dec(input);
elseif ...
        % other cases
end

Can you help me with a 'switch' setence?

[Stefany Romero]

[Fabio Freschi]

switch clause evaluate an expression, but your check is rather complicate. IMO a multiple if is simpler
