ctypes无法使用ctypes.open()加载dll文件 [英] ctypes is unable to load dll file using ctypes.open()

问题描述

此代码在我的计算机上正常工作，但是当我将其复制到具有所有先决条件的另一台计算机时，它停止在第5行:var lib = ctypes.open("C:\\ myapp \\ dl1.dll");

this code works properly on my machine but when i copy it to another machine with all its prerequisite it stops at line 5: var lib = ctypes.open("C:\\myapp\\dl1.dll");

function initport() 
{
Components.utils.import("resource://gre/modules/ctypes.jsm");
 
var lib = ctypes.open("C:\\myapp\\dl1.dll");

var ans= lib.declare("initPort" , ctypes.stdcall_abi , ctypes.int8_t );

alert("MessageBox result : "+ans());

lib.close();	

}

are there more requirements for JavaScript to load Dll?

推荐答案

0. dl1.dll在哪里?如果它不在C:\\myapp\\中，那么将找不到它.
1.您是否已在新计算机上注册dll?

0. Where is the dl1.dll? If it''s not in C:\\myapp\\ then it won''t be found.
1. Have you registered the dll on the new machine?
