So I just had a nasty runin with a 'array out of bounds' bug. At least dbpro would crash if you went out of bounds, c++ runs along like nothing is wrong, just to screw with you.

Anyway I was told I NEEDED to start using 'boost' array, so I downloaded it, but im at a loss as far as how to "include" it. I tryed adding the folders to my options -> vc++ directories (like I did for dark sdk) but that didnt work. I skimmed the boost site and all I saw was something about writing your own 'jam' program to include the library? Guh?

Zuh?

The array header doesn't require you to build a library to use it, so you don't need to bother with bjam.

You are on the right track as far as setting up your VC++ include directory. For example, I have boost installed in C:\DevLibs\boost_1_33_1 (that's where the index.htm file is), it's added to the include path, and I #include "boost/array.hpp".

Hurray for IanM! I dont know why that didnt work before... All I did was include the directory in my projects folder, then say #include "boost\array.hpp". Works great now



Now it crashes as it should! I wont even have to rewrite any of my code, just change the declarations!

And it DOESNT crash in release mode, which is good right? That means it doesnt waste time doing bounds checks in release mode?

hurray for boost!

Yep, when you use [] it uses asserts that only function when compiled in debug mode, and are compiled out in release mode. If you need runtime checking you can use the at() member function to get it to throw an exception if you go out of bounds.
