Getting the mouse key flags (fwKeys)

I would like to read the mouse key flags (fwKeys) which are passed by windows in the WM_MOUSEwhatever messages - outside of the message.
I think that there is a function for that, but I cannot find it.

Actually I bypassed my problem by using my own flag with is set or cleared with WM_LBUTTONUP/DOWN messages, but I want to know if there is an easier way to do so.

Simply use the 'GetKeyState()' API and provide 'VK_LBUTTON', 'VK_MBUTTON' or 'VK_RBUTTON' flags a the argument. If the high-order bit of the return value is 1, the key is down; otherwise, it is up.

Yes, I am sure (used this technique often ;-)

See winuser.h for the definitions (although I have to admit that both these constants as the API are not well documented..
