网络上流传腾讯QQ的截图动态链接库dll

我们讨论的不是rundll32.exe CameraDll.dll CameraSubArea这种执行命令的模式； 尝试使用ffi模块来引用； 尝试步骤[nodejs环境已经准备好]： 1、安装好vs2010; 2、安装ffi模块，npm install ffi一般编译成功; 3、CameraDll.dll文件放在D:\Program Files\nodejs目录； 4、编写如下代码运行，结果报错 var ffi = require(‘ffi’); var libm = new ffi.Library('D:/Program Files/nodejs/CameraDll.dll’, { 'CameraSubArea’: [ "void", []] //此函数无参数，无返回 }); libm.CameraSubArea(); 要扩大nodejs的使用范围，就必须能调用现有的代码模块dll/so等，所以需要尝试一下。 不知错误在哪里，请高手指点？ @ jiyinyiyong
