Question

I am trying to return a CArray from a function and trying to call the function from another class

short ListMaker::RetArray(CString szName, CArray<CString, CString&> &szarr_Names) {
    szarr_Names.Add(szName);
    return 0;
}

int main() {
    //..
    CArray<CString, CString&> myArray;
    ListMaker LM;
    short nCode = LM.RetArray(L"Name", myArray);
    //..
}

I am getting following errors:

Error   1   error C2664: 'RetArray' : cannot convert parameter 2 from 'CArray<TYPE,ARG_TYPE>' to 'CArray<TYPE,ARG_TYPE>'
Error   2   error C2511: 'short RetArray(CString,CArray<TYPE,ARG_TYPE> &)' : overloaded member function not found in 'ListMaker'

Please tell me the correct way to define and access the return value of the CArray.

Erm, frist of all if RetArray is a member of ListMaker class and you call it from main(), you cannot call it like this: short nCode = RetArray(L"Name", myArray);

If RetArray is a static member, use short nCode = ListMaker::RetArray(L"Name", myArray);. It it’s non-static, use instance, short nCode = listMakerInstance.RetArray(L"Name", myArray);.

Check your header file for RetArray declaration in ListMaker class. It might differ from the implementation in your cpp file, hence you get the C2511 error.
