An application sends a WM_GETHOTKEY message to determine the hot key associated with a window.
WM_GETHOTKEY wParam = 0; // not used; must be zero lParam = 0; // not used; must be zero
This message has no parameters.
The return value is the virtual-key code and modifiers for the hot key, or NULL if no hot key is associated with the window. The virtual-key code is in the low byte of the return value and the modifiers are in the high byte. The modifiers can be a combination of the following flags:
|
Value |
Meaning |
|
HOTKEYF_ALT |
ALT key |
|
HOTKEYF_CONTROL |
CTRL key |
|
HOTKEYF_EXT |
Extended key |
|
HOTKEYF_SHIFT |
SHIFT key |
These hot keys are unrelated to the hot keys set by the RegisterHotKey function.
