Hi all,

I'm using SetWindowHookEx with WH_KEYBOARD_LL to hook keys on keyboard, and the result, I can hook a single key such as Ctrl (VK_LCONTROL, VK_RCONTROL) or "A" key (0x41)

C++

if ((p->vkCode == VK_LCONTROL) || (p->vkCode == 0x41))

p is a pointer to (KBDLLHOOKSTRUCT *)(lParam)

However, I don't know how to hook multiple key "Ctrl + A", I used:

C++

if ((p->vkCode == VK_LCONTROL) && (p->vkCode == 0x41))

but there's no result...

Please help me.
Thank you

Hi OrginalGriff,

But when I try to change Ctrl key by Alt key (VK_MENU), it don't work???
Alt+A = not work
Ctrl+Alt+Del = not work

Once more, when I hook Ctrl + Alt only, when I press Alt key, after some seconds, I continue pressing Ctrl key, it's still hooked??

Please help me!

Try using:

C++

if (GetAsyncKeyState(VK_CONTROL) && (p->vkCode == 0x41))
