HKM_SETRULES message

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

Parameters

wParam

An array of flags that specify invalid key combinations. This parameter can be a combination of the following values:

Value	Meaning
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

lParam

An 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.

Return value

Remarks

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