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…

Accepted Answer

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);
```
