MFC using # import import ocx-CodePudding

Create an ocx, write a way:

 BSTR CAMFCocxTestCtrl: : ocxTest () 
{
Cstrings strResult; 
//TODO: Add your dispatch handler code here 
StrResult="asdffgh"; 

Return strResult. AllocSysString (); 
}

Then create MFC a button:

 # import "AMFCocxTest. Ocx \ 
"No_namespace no_smart_pointers raw_interfaces_only \ 
Raw_native_types no_implementation named_guids 

Void CMFCocx4Dlg: : OnButton1 () 
{
CoInitialize (NULL); 
{
If (1) 
{
_DAMFCocxTest * pOcx=0; 
Retrieves the hr=CoCreateInstance (
CLSID_AMFCocxTest,//Com object identifiers 
0,//a pointer to the interface IUnknown 
CLSCTX_ALL,//running executable code context 
DIID__DAMFCocxTest,//Com object interface identifier 
Reinterpret_cast & lt; Void * * & gt; (& amp; POcx)//used to receiving address Com object interface pointer variable 
); 
Assert (SUCCEEDED (hr)); 
If (pOcx) {
POcx - & gt; OcxTest (); 
POcx - & gt; Release (); 
} 
} 
} 
CoUninitialize(); 
}

Compile error: error C2039: 'ocxTest' : is not a member of '_DAMFCocxTest'
What reason is this?
