推荐答案

因为您的应用程序中只有一个应用程序... [rolleyes]

Because there is only one application in your application... [rolleyes]

在可执行文件中，必须有一个可以由加载程序，运行时等调用的入口点.
这里不能有任何歧义.

这就是为什么我们只能有一个<控制台程序中的c0>函数，而Windows程序中只有一个WinMain函数.这就是为什么我们只能有一个CWinApp或CWinAppEx实例的原因''，因为此类封装了可执行文件的入口点.

In an executable, there must be one entry point that can be called by the loader, runtime etc.
There cannot be any ambiguity here.

That is why we can have only one main function in a console program and only one WinMain function in a windows program. And that is exactly why we can have only one CWinApp or CWinAppEx instance ''cause this class encapsulates the entry point for the executable.
