/****************
1) 显示桌面:
很多软件有显示桌面的功能, 并且大家的方法都是遍历窗口, 然后让它们最小化, 其实 win系统给咱们了一个非常方便的WIN键(就是键盘上在CTRL键和ALT键之间的那个带win标志的按键), 利用它, 可以轻松的完成显示桌面的功能.
keybd_event(VK_LWIN, 0, 0 ,0);
keybd_event('M', 0, 0 ,0);
keybd_event('M', 0, KEYEVENTF_KEYUP ,0);
keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP,0);
其他的操作也类似, 比如直接显示开始的运行,就把上面的'M'换成'R'即可。
直接 keybd_event(VK_LWIN, 0, 0 ,0);
keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP,0);
直接显示“开始”对话框了。
2) 实现快速的全选
很多的时候，比如listctrl实现全选，你可以用listctrl循环设置每一项的状态为选中，多罗索的事情呀。用快捷键试一试CTRL＋A，其他的快捷键一样的用法，呵呵，你知道怎么办了吧？
keybd_event(VK_CONTROL, (BYTE)0, 0 ,0);
keybd_event('A',(BYTE)0, 0 ,0); //此处可以用 'A', (BYTE)65, 用'a'不起作用.
keybd_event('A', (BYTE)0, KEYEVENTF_KEYUP,0);
keybd_event(VK_CONTROL, (BYTE)0, KEYEVENTF_KEYUP,0);
3) 执行某些特殊的键，比如数字键，大小写，下面是数字键的例子
bool bState=true; //true为按下NumLock,false反之
BYTE keyState[256];
GetKeyboardState((LPBYTE)&keyState);
if( (bState && !(keyState[VK_NUMLOCK] & 1)) ||
(!bState && (keyState[VK_NUMLOCK] & 1)) )
{
// Simulate a key press
keybd_event( VK_NUMLOCK,
0x45,
KEYEVENTF_EXTENDEDKEY | 0,
0 );
// Simulate a key release
keybd_event( VK_NUMLOCK,
0x45,
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
0);
}
4） 你想CTRL＋ALT＋DELETE三键一起按下，
keybd_event(VK_CONTROL, 0, 0 ,0);
keybd_event(VK_MENU,0, 0 ,0);
keybd_event(VK_DELETE,0, 0 ,0);
keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYUP ,0);
keybd_event(VK_MENU,0, KEYEVENTF_KEYUP ,0);
keybd_event(VK_DELETE,0, KEYEVENTF_KEYUP ,0);
呵呵，这样不会成功呀，因为这几个键直接是操作系统来截获执行的，而模拟键盘只能发向应用程序，所以这种方法不行的（想显示锁定对话框，用 LockWorkStation();）
5） Window2000/NT/XP已经不提倡用这个函数了，上面的方法只是为了让大家开阔一下思路，怎么替代呢，呵呵，看下面，所以上面的所有代码都可以用这个来完成
//2000下用这个代替 ,包含 "winable.h"
INPUT input[4];
memset(input, 0, sizeof(input));
input[0].type = input[1].type = input[2].type = input[3].type = INPUT_KEYBOARD;
input[0].ki.wVk = input[3].ki.wVk = VK_LWIN;
input[1].ki.wVk = input[2].ki.wVk = 'R';
//接下来释放它，这一点很重要。
input[2].ki.dwFlags = input[3].ki.dwFlags = KEYEVENTF_KEYUP;
input[0].ki.time = input[1].ki.time = input[2].ki.time = input[3].ki.time = GetTickCount();
SendInput(4, input, sizeof(INPUT));
感觉比那个有点罗索，呵呵。

WIN键+E=快速打开资源管理器
WIN键+R=“运行”。
WIN键+M=全部视窗最小化。
WIN键+Shift+M=取消全部视窗最小化。
WIN键+F1=Help。
WIN键+F=“寻找”。
WIN键+Ctrl+F=显示“查找电脑”。
WIN键+Tab=切换工作列的程式。
WIN键+Break=显示系统内容。
