Are these non-modal in the same application? If so, you could do this:

class CDialog1 : public CDialog
{
  // Missing stuff...

public
  CStringArray m_Str;
};

class CDialog2 : public CDialog
{
  // Missing stuff...

public
  CDialog1 *m_pDlg1;
};

CDialog1 dlg1;
CDialog2 dlg2;

dlg2.m_pDlg1 = &dlg1;

dlg1.Create();
dlg2.Create();

Now dlg2 has access to dlg1.m_Str through it's m_pDlg1 member. Obviously, it'd be a good idea to encapsulate the public members.
