Without taking too much time, I would like to say that this project is a God-send.

I need to call a Windows function called HidD_GetPreparsedData(). It's second argument is a structure called _HIDP_PREPARSED_DATA. The MSDN documentation for this structure says, "The internal structure of a _HIDP_PREPARSED_DATA structure is reserved for internal system use." I'm not sure where to go from here. I've tried making a new class by extended Structure and PointerType, but I keep getting an access violation. Any help with this would be greatly, greatly appreciated.

This is the API for HidD_GetPreparsedData(): BOOLEAN HidD_GetPreparsedData( IN HANDLE HidDeviceObject, OUT PHIDP_PREPARSED_DATA *PreparsedData );

This is the available struct def for PHIDP_PREPARSED_DATA: typedef struct _HIDP_PREPARSED_DATA * PHIDP_PREPARSED_DATA;

Thank you for this project and keep up the great work!
