Raw input blues
Author
Hello....
Anyway, I was coding an input module for my engine, and I was trying to add support for raw input. However, the compiler said that the identifier RAWINPUTDEVICE was not defined. After a little poking around, I found the definition of the RAWINPUTDEVICE struct in Winuser.h. I also noticed that there was a section:
#if (_WIN32_WINNT >= 0x0501)
...
#endif
All the raw input stuff was within this #if. However, the text was gray (I'm using Visual C++, by the way), which means the #if failed. Does this mean that I'd have to upgrade my computer to use raw input? Please help!

As long as you're running Windows XP or higher you should be able to just #define the macro to whatever baseline you're targeting.

So, would I code something like this?
#define _WIN32_WINNT 0x0501
#include <windows.h>
#include <windowsx.h>
Thanks for the advice, by the way.

#include <windowsx.h>

You'd probably want to toss it in your project settings -- you'd have to #define it before every #include otherwise, including those #includes made by other libraries in headers you're using.
But yes, you've got the idea.

Um, not to sound totally decadent, but how exactly would I do this? (I'm still learning all the ins and outs of Visual C++.)
Right click on your project -> properties -> C++ settings -> Preprocessor settings
(can't remember the exact names, but something like that)
You can make project-wide #defines there

Mmmhmm. Definitions there are seperated by semicolons -- to #define it to a value, you'd use e.g. _WIN32_WINNT=0x0501
