Hi to all!
I am looking for a piece of code to be used to detect the keyboard "Caps
Lock" Led status (NOT the key status).
Thanks in advance.

The key status *is* the Led status when the Caps lock key is concerned:

    GetKeyState

    Return Values
        If the function succeeds, the return value specifies the status of
the given virtual key. If the high-order bit is 1, the key is down;
otherwise, it is up. If the low-order bit is 1, the key is toggled. A key,
such as the CAPS LOCK key, is toggled if it is turned on. The key is off and
untoggled if the low-order bit is 0. A toggle key's indicator light (if any)
on the keyboard will be on when the key is toggled, and off when the key is
untoggled.
