在Windows环境中从C或C ++访问COM接口

I'm relatively new to the Component Object Model specification - I have a simple question:

我对组件对象模型规范比较陌生 - 我有一个简单的问题:

How can I access a COM interface from a C or C++ application

如何从C或C ++应用程序访问COM接口

For instance, accessing Microsoft Excel COM interface to perform basic operations, without user intervention.

例如,访问Microsoft Excel COM接口以执行基本操作,无需用户干预。

Actually, you will need to instantiate the object using the COM interface.

实际上,您需要使用COM接口实例化对象。

This is fairly complicated, more than we can just answer here.

这是相当复杂的,我们可以在这里回答。

I would suggest looking into ATL if you are using C++, and using C++ if using C. It is very easy to use the #import construct to access COM objects in DLLs or EXEs.

如果您使用的是C ++,我会建议您查看ATL,如果使用C,我建议使用C ++。使用#import构造来访问DLL或EXE中的COM对象非常容易。

There is a wonderful article at Microsoft that seems to address this exact question. If you want to stick with straight C++ (i.e. MFC/ATL), you should check out the article as it has loads of sample code:

微软的一篇精彩文章似乎解决了这个问题。如果你想坚持使用直接C ++(即MFC / ATL),你应该查看文章,因为它有大量的示例代码:
