[Help] Souce key lock F5,F6,F7,ect..

[leooo007]

Hi good morning to the entire community!

Anyone can help me? I'm looking for a source to lock the keys F5, F6, F7ect .. keyboard.

On another forum I found the following:


HHOOK g_hHookKbdLL = NULL;
LRESULT CALLBACK KeyHookLL(int nCode, WPARAM wp, LPARAM lp);

BOOL APIENTRY DllMain(HINSTANCE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{


switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
g_hHookKbdLL = SetWindowsHookEx(WH_KEYBOARD_LL,KeyHookLL, hModule, 0);
break;
case DLL_THREAD_ATTACH:
break;
case DLL_THREAD_DETACH:
break;
case DLL_PROCESS_DETACH:
UnhookWindowsHookEx(g_hHookKbdLL);
g_hHookKbdLL = NULL;
break;
}
return TRUE;
}


LRESULT CALLBACK KeyHookLL(int nCode, WPARAM wp, LPARAM lp)
{
KBDLLHOOKSTRUCT *pkh = (KBDLLHOOKSTRUCT *) lp;

if (nCode==HC_ACTION)
{
if(pkh->vkCode==VK_F1) // Bloquear F1
{
return 1;
}
}
return CallNextHookEx(g_hHookKbdLL, nCode, wp, lp);
}

This source is supposed to lock the keys on the keyboard, but I can not make it work.

My OS is: windows xp sp3.
