C / C++ / MFC

void CParentDlg::DoDataExchange (CDataExchange *pDX)
{
   ...
   m_Child1.UpdateData (pDX->m_bSaveAndValidate);
   m_Child2.UpdateData (pDX->m_bSaveAndValidate);
   ...
}

From MSDN about DoDataExchange:

Never call this function directly. It is called by the UpdateData member function. Call UpdateData to initialize a dialog box’s controls or retrieve data from a dialog box.

}<br />

<br />
//othercode.cpp<br />

You don't have to do anything at all in the file where the function is written.
