Simple spoofer

So i spent long time thinking what else could i write in WinAPI that was within my abilities, and in internet i stumbled upon a forum post, of a person showing how you can disguise .exe file as another format, by a smart use of Left-to-right unicode override. I wrote complete code within a day, but it gave me errors, so i gave up. Now after a week or so i have returned to try and fix that code on one sleepless night, and i fix magically everything by adding "L" prefix in a part of the code. One letter makes things work. Too tired to be mad at myself.

Anyway about the program: You have to first select the executable you want to disguise, and then input what format you want to disguise the file as, and press Spoof. Program will then proceed to rename the file, adding a reversed format that user inputted, and then the Left-to-right override, reversing the reversed format (making it normal again) but also displacing the .exe part.

Program looks like this:

Here how the executable looks like, after spoofing, if you try to rename it manually.
