New to try/catch Can someone please explain to me just exactly this try/catch is doing? It doesn't seem to make any sense to me. Thank you in advance.
case '\r': if (Choice==(CancelIndex+1))return; try{(*Action[Choice-1])();} catch(...){} system("cls"); Choice = 1; break; case char(27): if ((CancelIndex+1)==ItemCount)return; try{(*Action[ItemCount-1])();} catch(...){} Choice = 1; break;

It's swallowing errors, basically ignoring them.

I'm a programmer. My attitude starts with arrogance, holds steady at condescension, and ends with hostility. Get used to it.

Is there really any reason to have in the code, or is this just a half-hearted attempt at trying to error detection?

Well, it has a legitimate purpose. The author probably didn't want exceptions to propagate beyond this scope. Without the catch, the unhandled exception would just go on until it hits the first catch or until it goes all the way out of the call stack, in which case the terminate function is called.
I'm not a fan of swallowing exceptions silently (at the very least it should be logged), but I wouldn't call it half-hearted either.
