在 visual studio 2010 中，如果我启动一个控制台项目并使用#include，它工作正常，但如果我启动一个 win32 项目并使用#include，它会在编译期间返回许多错误。
为什么？

最佳答案
缺少的是#include <ole2.h>或其中的一部分。
当WIN32_LEAN_AND_MEAN已定义 Ole2 是从 Windows.h 中删除的标题之一.
如果 INC_OLE2 可以加回 Ole2已定义。
如果你提供了一个标题并且不确定用户可能定义什么那么你可以为了安全起见
#if !defined(INC_OLE2) && defined(WIN32_LEAN_AND_MEAN)
#include <ole2.h>
#endif
#include <msxml2.h>
