HKM_SETRULES


HKM_SETRULES 
    wParam = (WPARAM) fwCombInv; 
    lParam = MAKELPARAM(fwModInv, 0);

Defines the invalid combinations and the default modifier combination for a hot key control.

fwCombInv
Array of flags that specify invalid key combinations. This parameter can be a combination of the following values:
HKCOMB_A ALT
HKCOMB_C CTRL
HKCOMB_CA CTRL+ALT
HKCOMB_NONE Unmodified keys
HKCOMB_S SHIFT
HKCOMB_SA SHIFT+ALT
HKCOMB_SC SHIFT+CTRL
HKCOMB_SCA SHIFT+CTRL+ALT
fwModInv
Array of flags that specify the key combination to use when the user enters an invalid combination. For a list of modifier flag values, see the description of the HKM_GETHOTKEY message.

When a user enters an invalid key combination, as defined by flags specified in fwCombInv, the system uses the bitwise-OR operator to combine the keys entered by the user with the flags specified in fwModInv. The resulting key combination is converted into a string and then displayed in the hot key control.
