DWORD vkCode;
DWORD scanCode;
DWORD flags;
DWORD time;
ULONG_PTR dwExtraInfo;
} KBDLLHOOKSTRUCT, *PKBDLLHOOKSTRUCT;
Members

vkCode
Specifies a virtual-key code. The code must be a value in the range 1 to 254.
scanCode
Specifies a hardware scan code for the key.
flags
Specifies the extended-key flag, event-injected flag, context code, and transition-state flag. This member is specified as follows. An application can use the following values to test the keystroke flags. Value Purpose
LLKHF_EXTENDED Test the extended-key flag.
LLKHF_INJECTED Test the event-injected flag.
LLKHF_ALTDOWN Test the context code.
LLKHF_UP Test the transition-state flag.

0
Specifies whether the key is an extended key, such as a function key or a key on the numeric keypad. The value is 1 if the key is an extended key; otherwise, it is 0.
1-3
