Which do you prefer, and why?
Personally, I prefer CodeBlocks as it's much more customizable and has a few extra features that Dev C++ doesn't.
The only thing I don't like about CodeBlocks is that the compiler will not run properly on Vista. Even with MinGW installed, upon running the compiler it returns a bunch of errors about library files not existing.
Marc i'm not sure what your talking about, I am running Vista and I use CodeBlocks just fine with no problems at all. The only problem I have is I can't make any DirectX file formats because i get the "library files not existing" type error as well.
