检查 MSDN [编写基于插件的应用程序

Check the MSDN[^]. If you can''t create a simple application, extending one will be problematic.


Writing Pluginbased Applications

如果您想要100您必须使用COM的％VB6解决方案.在一个VB6 DLL中定义COM接口，然后应用程序引用该DLL.现在，您编写的所有插件也将是实现此DLL的COM DLL.然后，该应用程序通过COM界面加载这些插件.插件可能需要添加到特定的注册表项，以便父应用可以枚举它们.

如果VB6和C/C ++的组合适合您，那么您可以使用基于C的插件模型.只需在C DLL中导出一些众所周知的(预定的)函数名(函数导出)，然后VB6可以P/调用这些DLL并调用这些众所周知的函数(P/Invoke不是正确的术语，我忘记了什么它曾经在VB6中被称为).

If you want a 100% VB6 solution you''d have to use COM. Define the COM interface in one VB6 DLL, and then app references this DLL. Now any plugins you write will also be COM DLLs that implement this DLL. The app then loads these plugins via the COM interface. The plugins may need to be added to a specific registry key so the parent app can enumerate them.

If a mix of VB6 and C/C++ will work for you, you can have a C based plugin model. Just export some well-known (pre-decided) function names in the C DLLs (function exports), and then VB6 can P/Invoke these DLLs and invoke these well known functions (P/Invoke is not the right term, I forgot what it used to be called in VB6).
