Raw Input Registration Problems, RegisterRawInputDevices()

[Peter5897]

Hi,

I've never worked with raw input before and I'm having trouble even getting to a situation where I can receive WM_INPUT messages. I've been reading the MSDN page on raw input (link) but I'm having trouble deciphering what I actually need to do.

Right now I have this code:

	RAWINPUTDEVICE rawInputDevices;

	rawInputDevices.hwndTarget     = 0;
	rawInputDevices.usUsagePage    = 0x01;
	rawInputDevices.usUsage        = 0;
	rawInputDevices.dwFlags	       = RIDEV_PAGEONLY;

	RegisterRawInputDevices( rawInputDevices_, 1, sizeof(rawInputDevices) );

Which from what I have seen should work but RegisterRawInputDevices always returns false and calling GetLastError() returns an error code of 998 (ERROR_NOACCESS) meaning an Invalid access to memory location. I read that the error might have something to do with AntiVirus/Firewall software but disabling my firewall returned the same results.

Any help would be greatly appreciated, thanks.

***Edit***
After working on this for about an hour I finally decided to seek some help. Then right after posting I saw my problem... instead of using the RID variable I just created I'm using a member variable which is still sticking around from other attempts.
