Parameters

  • pDX
    A pointer to a CDataExchange object. The framework supplies this object to establish the context of the data exchange, including its direction.

  • nIDC
    The ID of an edit control in the dialog box, form view, or control view object.

  • value
    A reference to a data member in the dialog box, form view, or control view object. The data type of value depends on which of the overloaded versions of DDX_Text you use.
