之前專案在做C++對接AS3的時候，
對雙方資料交換處理上有弄成一個類方便來使用

用法如下：

	//查找窗口名稱，強制關閉窗口
	FREObject NativeAneManager::closeWindow(FREObject windowname)
	{
	bool isHasHwd = false;
	//取得窗口
	HWND hwd = FindWindow( NULL, AneDataConvert::ToUTF8_LCPW(windowname)); //window Name
	if(hwd)
	{
	SendMessage(hwd, WM_SYSCOMMAND, SC_CLOSE, 0);
	isHasHwd=true;
	}
	return AneDataConvert::AsBool(isHasHwd);
	}
