You can always try the method described in the guides, with whatever development environment you want, followign advice of whoever you want to advise you, or following any guides you find, here or elsewhere.
It's just that you said you'd like the one-click solution, and I told you it exists. That doesn't mean it's the only way. To compile a modded dll, or to compile a debug dll, a few steps still have to be taken even with VS 2003, you don't alwas get an instantaneaous dll, it's just the environment used by the developers of the game, so it's normally less hassle than any other way. Still, there are other ways, and if you can't get VS 2003 all this talking from my side was for nothing anyway.
