提问by Lucie kulza
I'm trying to build my first ATL DLL project, in which I'm using ADODB. The issue here is that I'm getting each ADODB class underlined
我正在尝试构建我的第一个 ATL DLL 项目，在该项目中我使用了 ADODB。这里的问题是我给每个 ADODB 类都加了下划线
ADODB::_ConnectionPtr spADOConnection;
when I pass the mouse over on ADODB::_ConnectionPtrI get name followed by '::' must be a class or namespace namespADOConnectionI get expected a ';'. What's the mean of this, please? How do I to fix it please?
当我通过鼠标悬停在ADODB::_ConnectionPtr我得到name followed by '::' must be a class or namespace namespADOConnection我得到expected a ';'。请问这是什么意思？请问我该如何解决？

The compiler is unable to locate the declaration of ADODB. Make sure you include the relevant header in the translation unit where the compiler complains.
编译器无法定位 的声明ADODB。确保在编译器抱怨的翻译单元中包含相关标题。
