工程目录如下：

1.首先编写idl文件

import "oaidl.idl";
import "ocidl.idl";
[
        uuid(80DDC35E-320E-4f9c-979F-522DDCD34FD3),
        dual,
        oleautomation
]

interface IXGUtilitiesInterface : IDispatch {
        HRESULT Hello([in] INT a, [in] INT b, [out, retval] INT *presult);
}
[
      uuid(78FBDE61-B979-47cf-B3EC-15F7814E58B1)
]

library XGUtilitiesLib
{
        importlib("stdole2.tlb");
        [uuid(ED2A47D0-D7CC-4edd-8C17-61361EB1B851)]
              coclass XGUtilitiesObject {
              [default] interface IXGUtilitiesInterface;
        };
};

2.编译idl文件

打开vs 命令行工具cmd，midl XGUtilities.idl /tlb XGUtilities.tlb 在同目录下面生成tlb文件

我的插件是 XGUtilities.tlb

3.编写com实现

# -*- coding: gbk -*-
import comtypes
import comtypes.server.localserver
from comtypes.client import GetModule
#每次改动时需要执行一次，打包时无需执行
#GetModule("XGUtilities.tlb")
from comtypes.gen.XGUtilitiesLib import XGUtilitiesObject
class XGUtilitiesObjectImpl(XGUtilitiesObject): 
    _reg_threading_ = "Both"
    _reg_progid_ = "XGUtilitiesLib.XGUtilitiesObject.1"
    _reg_novers_progid_ = "XGUtilitiesLib.XGUtilitiesObject"
    _reg_desc_ = "许刚工具集"
    _reg_clsctx_ = comtypes.CLSCTX_INPROC_SERVER | comtypes.CLSCTX_LOCAL_SERVER
    _regcls_ = comtypes.server.localserver.REGCLS_MULTIPLEUSE
    
    def Hello(self,a, b):
        return a + b

if __name__ == '__main__':
    from comtypes.server.register import UseCommandLine
    UseCommandLine(XGUtilitiesObjectImpl)

4.编写py2exe打包

# -*- coding: gbk -*-
from distutils.core import setup
import py2exe
import sys

manifest = """
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">

</assembly>
"""

class Target:
    def __init__(self, **kw):
        self.__dict__.update(kw)
        self.version = "0.0.0"
        self.company_name = "http://blog.csdn.net/xugangjava"
        self.copyright = "@2012,power by 许刚"
        self.name = "http://blog.csdn.net/xugangjava"

my_com_server_target = Target(
        description = "许刚工具集",
        modules = ["XGUtilities"],
        other_resources = [
                           ("TYPELIB", 1,open(r"XGUtilities.tlb", "rb").read()),
                           (24,1,manifest),
        ],
        create_exe = False
)

setup(
    name="许刚工具集",
    options={"py2exe": {
        "compressed": 2,
         "dll_excludes": ["mswsock.dll", "powrprof.dll"],
         "includes":["comtypes.gen._78FBDE61_B979_47CF_B3EC_15F7814E58B1_0_0_0"]
    }},
    zipfile=None,
    version="0.0.0",
    description="许刚工具集",
    author="许刚",
    author_email="http://blog.csdn.net/xugangjava",
    ctypes_com_server=[my_com_server_target]
)

运行打包 python setup.py py2exe

reg.bat 内容

regsvr32 XGUtilities.dll

运行注册

接下来来测试这个插件

Test.html内容

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>  
<head>  
	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
	<SCRIPT LANGUAGE="JavaScript">
	    window.onload = function () {
	        var obj = new ActiveXObject("XG.Utilities");

	        alert(obj.Hello(1,3));
	    }
	</SCRIPT>
</head>  
<body>  
</body>  
</html>

打开html 测试成功

为了验证兼容性，插件是否依赖python环境，

在没有安装python的环境中测试是否能注册插件，在2003虚拟机（没有安装python环境）下注册插件后

这里html修改为

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>  
<head>  
	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
	<SCRIPT LANGUAGE="JavaScript">
	    function Hello() {

	        var obj = document.getElementById("obj")

	        alert(obj.Hello(1,3));
	    }
	</SCRIPT>
</head>  
<body>  
<object id="obj" width="100" height="100" classid="clsid:ED2A47D0-D7CC-4edd-8C17-61361EB1B851" ></object>
<input type="button" value="Hello" οnclick="Hello()"/>
</body>  
</html>

希望大家通过本文的介绍，可以用python快速开发出自己的ActiveX 插件
