Hello, it's quite often, that someone asks how to change the texts of the MsgBox buttons or the InputBox buttons or how to change the position of ta MsgBox. Since years I use CBT hooks for that, but now I made a small UDF out of it for the ease of use. Of course you can build your own GUI or use already existing UDFs to do the same, but I like this way and you can hack (hook) the inbuild InputBox.
