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.

Remarks

The DDX_Text function manages the transfer of int, UINT, long, DWORD, CString, float, or double data between an edit control in a dialog box, form view, or control view and a CString data member of the dialog box, form view, or control view object.
