a wchar_t type (note that BSTR and LPWSTR resolve to wchar_t*), you may get an LNK2001 unresolved external symbol error.This error is caused by the /Zc:wchar_t compiler option, which is set to on by default in new MFC projects. This option causes the compiler to treat wchar_t error lnk2019 unresolved external symbol visual studio 2010 as a native type. Before Visual C++ .NET, wchar_t was treated as an unsigned short.If the main project and library do not use the same setting for /Zc:wchar_t, this will cause a mismatch of function signatures. To avoid this problem, rebuild the library with the /Zc:wchar_t compiler option, or turn it off in the main project using the Treat wchar_t as Built-in Type setting on the Language property page in the Property Pages dialog box.
