      dll控件常规安装方法（仅供参考）：
      下面是32系统的注册bat文件
      可将下面的代码保存为“注册.bat“，放到dll目录，就会自动完成dll注册(win98不支持)。
      @echo 开始注册
      copy Fnthex32.dll %windir%\system32\
      regsvr32 %windir%\system32\Fnthex32.dll /s
      @echo Fnthex32.dll注册成功
      @pause
      下面是64系统的注册bat文件
      @echo 开始注册
      copy Fnthex32.dll %windir%\SysWOW64\
      regsvr32 %windir%\SysWOW64\Fnthex32.dll /s
      @echo Fnthex32.dll注册成功
