绿软必备：ActiveXDLL免注册调用的方法(改良自阿国哥的源码)

转自：http://blog.csdn.net/modest/archive/2007/09/01/1767950.aspx    （魏滔序原创）

阿国哥的代码(找到链接后再补上)，我稍微改良了一下，做绿色软件的朋友肯定用的到。
IDE下可以引用那个dll使用。编译后可以在未注册dll的计算机上正常工作了。

使用方法：
Dim pDll As Long '记录Dll，用来最后完美释放
Dim Update As Update.Handle '要实例化的对象
Set Update = LoadObjectByName(App.Path & "/Update.dll", "Handle", pDll) ' New Update.Handle
If Update Is Nothing Then Exit Sub
Update.Test '<--类中的方法
Set Update = Nothing '<-----这句不能少，否则会出现意外错误
UnLoadDll pDll '<----释放

模块中：
Option Explicit

Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, ByVal lpProcName As String) As Long
