UINT SendInput( UINT nInputs, LPINPUT pInputs, int cbSize );
函数说明：
该函数合成键盘事件和鼠标事件，用来模拟鼠标或者键盘操作。事件将被插入在鼠标或者键盘处理队列里面。
参数说明：
nInputs 指定ninput 数组中元素的个数。就是插入事件的个数。
pInputs 指向一个类型为INPUT的 数组变量，该数组中的每个元素代表一个将要插入到线程事件中去的键盘或鼠标事件。
cbSize 指定INPUT结构的大小。如果cbSize不是INPUT结构的大小，则函数将失败返回
搜索框
Hook了Explorer的进程的SendInput，然后在文件的搜索框中执行右键-粘贴，通过打印log看到

翻译一下log的意思是
按下Contorl ---- 按下V-----抬起V----抬起Control。 完全模拟了一次粘贴的操作。
其中log代码
UINT WINAPI HOOK_SendInput(
UINT nInputs,
LPINPUT pInputs,
int cbSize)
{
for (size_t i = 0; i < nInputs; i++)
{
if (pInputs[i].type == INPUT_KEYBOARD)
{
CString stroutput;
stroutput.Format(L"keyboard message::wVk=0x%04x,wScan=0x%04x,dwFlags=0x%08x\n", pInputs[i].ki.wVk, pInputs[i].ki.wScan, pInputs[i].ki.dwFlags);
OutputDebugString(stroutput.GetBuffer());
}
else if (pInputs[i].type == INPUT_MOUSE)
{
OutputDebugString(L"mouse message\n");
}
}
return REAL_SendInput(nInputs, pInputs, cbSize);
}往哪个窗体发我们可以获得
DWORD dwProcessId = 0;
HWND hwnd = GetForegroundWindow();
if (hwnd)
{
GetWindowThreadProcessId(hwnd, &dwProcessId);
