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.
