I need a little help on hotkeys. That is, how can i turn say CTRL-ALT-F1 into a hotkey, then check it at runtime. I suppose it's RegisterHotKey at the program's initialisation, then check for WM_HOTKEY in the mesage loop.
Also, how can this be done by setting a keyboard hook?
Code snippets would be highly appreciated.
Thank you in advance,
tank_ ;)
what you supposed is right. do as following to register a CTRL+Alt+F1 hotkey:
invoke RegisterHotKey,hWin,065h,MOD_CONTROL or MOD_ALT,VK_F1
Well, i have followed the instructions but wasn't able to register it. Maybe someone could post a small listing of an app that actually registers a key combination.
thank you

Hi,
;------------------------------------------------------------------------------
; API "RegisterHotKey" defines a hot key for the current thread
;------------------------------------------------------------------------------
push 1Bh ;uVirtKey, virtual-key code, VK_ESCAPE=1Bh
push 0h ;fuModifiers, key-modifier flags
push 0B00h ;idHotKey, identifier of hot key
push WP1_hWnd ;hwnd, window receive hot-key notification
call RegisterHotKey ;- API Function -
In your Window Proc check the WM_HOTKEY (value=312h) message.
WM_HOTKEY :
idHotKey = (int) wParam; // identifier of hot key
fuModifiers = (UINT) LOWORD(lParam); // key-modifier flags
uVirtKey = (UINT) HIWORD(lParam); // virtual-key code
;==============================================================================
; WM_HOTKEY (value=312h) message received ?
;------------------------------------------------------------------------------
WP1_uMsg_312h:
cmp eax,312h ;check if WM_HOTKEY message recieved
jne WP1_return ;if not goto label
jmp WP1_return
