    Pointers as you probably know are handles to memory in data.....without them your code will never get far as your compiler will spend all its time copying memory from here to there, and you will miss out on the neat stuff C allows you to do......just keep working and working at them if you are not sure...dont listen to people who tell you you can get by without them!

    As for Dlls.....have a look at the windows board......members (incluing myself) have posted examples there

    Well, you can get by without them, up to a point... just use lots and lots and lots of global variables. But as Fordy said, don't listen to me

    Oh yeah, actually you can scratch off most of (if not all of) the global variables. Just use references instead of pointers That should simplify things. But that's not saying that pointers aren't useful! "char*" is your bestest bestest friend.
    Just Google It. √

    ...which is against the principal of least privalage....will make your exe bigger than needed...and the one time you need more memory than you have provided for, your smoked!!!!!!!

    Best bet....learn to live with pointers
