Question

Not sure why I can’t take CDialog and set the memory space in the cpp file. It only works in the header file. Isn’t this the same thing??? thanks

---

Header file:

public:
    CDialog *m_pages[6];  // this works

---

Header file:

CDialog *m_pages;

cpp file

m_pages = new CDialog[6];  //this fails

---

After seeing what I did wrong(1st poster: “creating an array of six pointers to CDialog”).
This is what I missed: (and now it works!)

CDialog **m_pages = new CDialog*[6]; //double pointer

Check the documentation. CDialogs require at least one parameter in their constructor, that’s why you can’t allocate them in your second example, since they don’t have a default constructor.

In your first example, you’re creating an array of six pointers to CDialog. That is completely different from an array of six CDialog, which is what you are trying to allocate in the second one.
