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 

ADODB::_ConnectionPtr spADOConnection;

when I pass the mouse over on ADODB::_ConnectionPtr I get name followed by '::' must be a class or namespace name spADOConnection I get expected a ';'. What's the mean of this, please? How do I to fix it please?

Thanks a lot!

    looks like C++ doesn't know that ADODB is a class or namespace, is everything correctly included/linked in your project? Are you getting any external symbol errors during compilation? – Syntactic Fructose Apr 07 '14 at 20:35
  • @Gmercer015, I've correctly included `msado60.dll`, yes I'm getting an external symbol on `LNK2001: unresolved external symbol "public: virtual long __stdcall CTProcessus::Init(class ATL::CStringT > >,wchar_t *,wchar_t *,wchar_t *)"` – Lucie kulza Apr 07 '14 at 20:43

    You don't include DLLs, you include header files. – juanchopanza Apr 07 '14 at 20:49
  • @Luciekulza as juanchopanza said, your .dll would be placed in the same directory as your executable. It's not something you would include from the properties page – Syntactic Fructose Apr 07 '14 at 21:00

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.

    The compiler has got nothing to do with DLLs which come at a much later stage. This is more at the code generation phase where the compiler needs to verify the type you're trying to use. There should be a header where the type `ADODB` is introduced. Make sure it's included in the source file you're trying to compile. – legends2k Apr 07 '14 at 20:47
