Exceptions

[Tresky]

Hey guys,
I'm trying to figure out how to use exceptions, but I don't get it. Here is something I have in the constructor of one of my classes. Does this even make sense?

bool Engine::LoadMaps(string _source) {
	string temp = "";
	std::ifstream map_list(_source);
	if (!map_list) // Does this throw make any sense?
		throw std::exception("Error: Failed to open MapList.txt", 1);
	while (getline(map_list, temp))
		if (!maps.LoadMap(_source + '\\' + temp)) // This one as well?
			throw std::exception("Error: Failed to load maps", 2);
	map_list.close();
	return true;
}

If so, how would I catch those exceptions?

Hey, u'r missing 'try' and 'catch' blocks if u want to use exception handling tho I woulnd't recommend it here for stuff like ifstream since it already has ways for u to check to see if the stream is functional.

U should have ur written error msgs in the 'catch' blocks. This explains it all quite well:
