DWORD GetThreadID(HANDLE hThread,DWORD dwProcessId)

	if(hTempThread==hThread){//如果指定线程句柄与打开句柄相同

//问题出在这里，我有2台4核电脑，一台双核，一台单核；单核机和双核机运行正常，两台四核电脑上运行找不到相同的句柄

//一台四核装的win7，其他3台电脑装的都是完全相同的XP系统，在四核电脑上跟踪调试hTempThread都是3-4位数的句柄，

//hThread都是5位数的句柄，为什么会这样呢？该怎么修改啊？

                ::CloseHandle(hTempThread);

                ::CloseHandle(hThreadSnap);

                return te32.th32ThreadID;//返回句柄

	}else{

	  ::CloseHandle(hTempThread);

         }

        }

    }

    return 0;

}

主调程序：



HWND hwndHandle = FindWindow("TForm_Client","辅助工具");

if(hwndHandle)

{

	unsigned long PID;

	GetWindowThreadProcessId(hwndHandle,&PID);	

	HWND hdwWnd = FindWindowEx(hwndHandle, NULL,"TPageControl",NULL);

	hdwWnd = FindWindowEx(hdwWnd, NULL,"TTabSheet","登录");

	hdwWnd = FindWindowEx(hdwWnd, NULL,"TButton","登录.L");

         PID=GetThreadID(hdwWnd,PID);

         ……
