Windows Office 2010中的VBA套接字连接

简短问题
是否有一个库可以取代用于在VBA应用程序中创建和维护套接字连接的mswinsoc.osx

背景
我正在尝试在Visio 2010 Professional文档中创建套接字连接。我找到了一种在Windows 7上注册mswinsoc.osx的方法，但这似乎很奇怪，因为微软放弃了一个用于建立套接字连接的库，而没有（更好的）替换它。让我更担心的是，使用Office 2010的Winsoc库的例子很少甚至没有。我不支持旧文档，所以Winsoc不是一个要求；这只是我知道会有用的秘密

其他想法
我为Visio找到了一些非常有用的VBA内容，使我相信应该有一个新的解决方案

---

任何Office 2010的套接字连接示例或了解mswinsoc.osx发生了什么都会有很大帮助

简短回答

附加信息
我在C和VB中找到了一些使用此DLL的详细示例。

到目前为止，由于我的项目范围发生了变化，我还没有机会在VBA中运行任何示例。相反，我使用Python通过连接控制Visio，取得了巨大成功

我制作了vba登录客户端（ws2_32.dll）示例

它可能工作得很好（我测试过）
