Trying to pass a CStringArray gives error cannot access private member declared in class 'CObject'

Question

I'm getting a strange error telling me that I cannot access private member declared in class 'CObject' when simply trying to pass a CStringArray to a function I have written to break it up into pieces. I've commented out my entire function code so I know that the problem resides within the passing of the object itself, I'm assuming that I'm doing so incorrectly.

Here is my code:

    // If successful, read file into CStringArray
    CString strLine;
    CStringArray lines;
    while (theFile.ReadString(strLine))
    {
        lines.Add(strLine);
    }

    // Close the file, don't need it anymore
    theFile.Close();

    // Break up the string array and separate it into data
    CStringArrayHandler(lines);

Here is my CStringArrayHandler function:

void CSDI1View::CStringArrayHandler(CStringArray arr)
{
    // Left out code here since it is not the cause of the problem
}

Here is the declaration of the function in my header file:

class CSDI1View : public CView
{
// Operations
public:
    void CStringArrayHandler(CStringArray arr);   // <<<<===================

And here is the full text of the error I am getting:

Error 1 error C2248: 'CObject::CObject' : cannot access private member declared in class >'CObject' c:\program files (x86)\microsoft visual studio 12.0\vc\atlmfc\include\afxcoll.h 590 1 >SDI-1

Try passing the array to CStringArrayHandler by reference. – user1793036 Nov 21 '14 at 00:54 — user1793036, Nov 21 '14 at 00:54

You are passing CStringArray arr by value, so the copy constructor for CStringArray must be accessible. But it isn't, because CStringArray inherits from CObject which prohibits copying (that's what the compiler error message, which you actually didn't fully paste here, is saying)

The solution is to pass arr by reference:

void CStringArrayHandler(const CStringArray& arr);

The text of the error that I posted is all VS2013 gave me. Thanks, I'll try this – JayB Nov 21 '14 at 00:59
@user134788 OK maybe, I don't have VS at hand, but I was under impression it should at least print the inaccessible constructor signature, that is `CObject(const CObject&)` – Anton Savin Nov 21 '14 at 01:01
Though I wanted to actually operate on a CStringArray passed by reference. I cannot do it with const. Even tried using CArray seems to have the same problem. :( – Ozair Kafray Jun 26 '18 at 11:44
@OzairKafray worth asking a new question perhaps? – Anton Savin Jun 26 '18 at 17:45
