Not a windows programmer, so I don't have much feedback on the source structure, but this is a really fun and creative puzzle layout for programmers :)
It's a fine line between "fun puzzle" and "this feels a little too much like debugging code at $work", and you certainly landed on the "fun" side. If you explore this idea further, I'd see if you can improve the parser so that a wider range of solutions will work: my silly approaches like 11 - -11 - -1 - -1 - -1 - -1 - -1 for 27 made it think I was missing a semicolon. Good work!
