Thread: DirectX9 compile errors

So, given that no one wanted to tackle the last post (and I don't blame you either-- it was a doozie!)... I decided I'd try to simplify things a bit, and stick to one file-- after all, I'm still learning the basics of DirectX 9 here...

Again, I'm getting compile errors... Is anyone willing to take a stab at this (or be willing to refer me to someone/somehere who might know)?? It's driving me absolutely nuts, and I have no idea where to go now...

Thanks!
