My linker doesn't like D3D external symbols

[soccermiles]

I have been trying to learn DirectX 9, but unfortunately, I can't compile any of the later files. I think it is something in the settings, but I checked and couldn't find any differences. Here is the code for the first one that won't compile properly... The error I get is that the linker complains about unresolved external symbols once for every D3D-related function. Sorry to spam you with code, but I have no idea where this is coming from...It might be from somewhere in preprocessor directives (Unresolved External symbols thingy). Maybe try compiling it urself.

Again, sorry about the code-spamming.
BTW: It all seemed to start when I enabled Z-buffers
