1. Add the control variable to your dialog header file(CEdit m_myEdit;)
2. On your implementation file, add a line to the DoDataExchange method (DDX_Control(pDX, IDC_MY_EDIT, m_myEdit);, where IDC_MY_EDIT is the ID of the Edit Box)
3. On your code now you can use the m_myEdit for controlling the edit box. (m_myEdit.SetWindowText("bla bla bla");)
