Enable CUDA syntax highlight & intellisense for Visual Studio

Syntax highlighting like __global__...
Goto "C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK 3.2\C\doc\syntax_highlighting"
Read the readme.txt there, basically there is simple step as following

Want pretty syntax highlighting when editing your .cu files in Visual Studio?
Here's how:

---
Visual Studio .Net 2005 / Visual Studio 8:

1. If you don't have a usertype.dat file in your "Microsoft Visual Studio 8\Common7\IDE" folder, then copy the included usertype.dat file there.  If you do, append the contents of the included usertype.dat onto the end of the "Microsoft Visual Studio 8\Common7\IDE\usertype.dat"

2. Start Visual Studio 8.  Select the menu "Tools->Options...".  Open "Text Editor" in the tree view on the left, and click on "File Extension".  Type cu in the "Extension" box, set the editor to "Microsoft Visual C++" and click "Add".  Click "OK" on the dialog box. 

3. Restart Visual Studio and your CUDA code should now have syntax highlighting.

For intellisense support
Go to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\extras\visual_studio_integration, read the NvCudaRules.README.txt or run the .reg there, it will append the cu, cuh into registry entry as following

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\Languages\Language Services\C/C++]
"NCB Default C/C++ Extensions"=".cpp;.cxx;.c;.cc;.h;.hh;.hxx;.hpp;.inl;.tlh;.tli;.cu;.cuh;.cl"

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Languages\Language Services\C/C++]
"NCB Default C/C++ Extensions"=".cpp;.cxx;.c;.cc;.h;.hh;.hxx;.hpp;.inl;.tlh;.tli;.cu;.cuh;.cl"

Last but not least, you'll need to include following header files in your CUDA project in order to get intellisense read those headers.

#include "cuda.h"
#include "cuda_runtime.h"
#include "device_launch_parameters.h"

I really recognize that VS is sux and eclipse should be better. But Nsight only on VS :-(
