Hi,
I create a C++/WinRT Windows Console Application project and try to implement the IDispatch interface.
This is the class.h
And following is class.cpp. In the method GetIDsOfNames, I am trying to use the method DispGetIDsOfNames from oleauto.h header.
However, it gets the complier error that *Error LNK2019 unresolved external symbol __imp_DispGetIDsOfNames referenced in function "public: virtual long __cdecl int __cdecl main(void)'::2'::MyCoclass::GetIDsOfNames(struct _GUID const &,wchar_t * *,unsigned int,unsigned long,long )" (?GetIDsOfNames@MyCoclass@?1??main@@YAHXZ@UEAAJAEBU_GUID@@PEAPEA_WIKPEAJ@Z)
