怎样屏蔽热键？

[wuliangge2001]

因为程序的特殊性，我想实现在进入程序时，使低级用户不能用ctrl+alt+del和alt+tab和windows键，怎样实现？有这样的类吗？

[puma5]

利用key input API 重新设置快捷键即可

[puma5]

没有相关的MFC CLASS

[wuliangge2001]

key input API ?能不能说的详细一些？

[wuliangge2001]

有没有人会？帮帮忙吧

用hook吧

可以用SystemParametersInfo试试看^_^

把Ctrl+Esc,Alt+Tab，Alt＋F4，Alt＋Esc全屏蔽。



#define _WIN32_WINNT 0x0500
#include <Windows.h>

LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam) {

BOOL fEatKeystroke = FALSE;

if (nCode == HC_ACTION) {
switch (wParam) {
case WM_KEYDOWN:
case WM_SYSKEYDOWN:
case WM_KEYUP:
case WM_SYSKEYUP:
PKBDLLHOOKSTRUCT p = (PKBDLLHOOKSTRUCT) lParam;
fEatKeystroke =
((p->vkCode == VK_F4) && ((p->flags & LLKHF_ALTDOWN) != 0)) ||
((p->vkCode == VK_TAB) && ((p->flags & LLKHF_ALTDOWN) != 0)) ||
((p->vkCode == VK_ESCAPE) && ((p->flags & LLKHF_ALTDOWN) != 0)) ||
((p->vkCode == VK_ESCAPE) && ((GetKeyState(VK_CONTROL) & 0x8000) != 0));
break;
}
}
return(fEatKeystroke ? 1 : CallNextHookEx(NULL, nCode, wParam, lParam));
}
