Question

嘿，我在VS C ++ 2008中使用向导创建了一个对话框基础应用程序。没有添加我自己的任何代码。当我编译时，我得到一些错误，说CWinAppEx未定义。

Answer 1

CWinAppEx仅在您安装了Visual Studio 2008 SP1时可用，我认为您已经拥有了Visual Studio 2008 SP1，因为您可以使用使用CWinAppEx的向导代码生成。

CWinAppEx位于afxwinappex.h中，也许你在stdafx.h标题中没有这个包含。

Answer 2

CWinAppEx是Visual Studio 2008 Feature Pack的一部分，其中包含用于功能区用户界面的MFC类。

这是它的MSDN页面（注意它是在Visual Studio 2008类别的MFC Feature Pack下）： http://msdn.microsoft.com/en-us/library/bb983877.aspx
