Hi, I am trying to combine my project with ProUIS GUI, and get 1 error, as following:

error LNK2019: unresolved external symbol "class CDlgFileOper dlgFileOper" (?dlgFileOper@@3VCDlgFileOper@@A) referenced in function "public: void __thiscall ABPlusV::OnBrowseCopyFileTo(void)" (?OnBrowseCopyFileTo@ABPlusV@@QAEXXZ)

How could I resolve it ?

PS: my vs environment:
Use MFC in a shared DLL
Not using ATL
Use Unicode Character Set

Your application and the library build should use the same settings for the compiler option Treat w_char as Built-In type when Unicode is used. The article Compatibility with Built-In Unicode Character Type may be useful with regard to this issue.
