求救 模拟按键问题

[moruoli]

想实现一个模拟按键的小功能，每隔五秒钟就会单击一下左键
我用全局钩子截获鼠标中键点击事件，从而模拟单击左键功能
if(WM_MBUTTONDOWN == wParam)
{
POINT pt;
GetCursorPos(&pt);
// while(1)
// {
SetCursorPos(pt.x,pt.y);
mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
// Sleep(5000);
// }
}
else
return CallNextHookEx(g_hMouse,nCode,wParam,lParam);

可现在是当单击了一次中键，它就响应一次，怎么实现单击一次中键后，它每隔五秒钟自己就会
响应一次？（加while和sleep是实现不了的）请各位大侠赐教，谢谢啊

#include <windows.h>
#include <process.h>
HHOOK g_hMouse=NULL;
HWND g_hWnd = NULL；
//// 子线程函数
unsigned _stdcall SecondThreadFunc(void *pArguments)
{
POINT pt;
GetCursorPos(&pt);
while(1)
{
SetCursorPos(pt.x,pt.y);
mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
Sleep(5000);
}

_endthreadex(0);
return 0;
}

//// 鼠标钩子函数
LRESULT CALLBACK MouseProc(
int nCode, // hook code
WPARAM wParam, // message identifier
LPARAM lParam // mouse coordinates
)
{
if(WM_MBUTTONDOWN == wParam)
{
HANDLE hThread;
unsigned threadID;
hThread=(HANDLE)_beginthreadex(NULL,0,&SecondThreadFunc,NULL,0,&threadID);
WaitForSingleObject(hThread,INFINITE);
// CloseHandle(hThread);
}
}
else
return CallNextHookEx(g_hMouse,nCode,wParam,lParam);

}

void SetHook(HWND hwnd)
{
g_hWnd=hwnd;
g_hMouse=SetWindowsHookEx(WH_MOUSE,MouseProc,GetModuleHandle("Hook"),0);
}



照上面那样写，也实现不了每隔五秒钟自己模拟按键一次的功能，并且会死机

各位帮帮忙，看看怎么弄啊

[moruoli]

已经解决，把WaitForSingleObject(hThread,INFINITE);去掉就可以了

开个子线程sleep不行啊

[moruoli]

对线程我不太懂，很模糊，能说的更明白些吗？
