Save - worked example

key : purple - original code / blue - new code

Step 1 :

Continue with the program names.

Step 2 :

Change the m_NameList definition as shown below (the pointer list must be of type CObList to allow saving) :

private:

// define the CTypedPtrList m_myList
CTypedPtrList<CObList, CName*> m_NameList;

Step 3 :

To allow the CName class to read and save data add the following definitions to the header (private access) :

DECLARE_SERIAL(CName);
void Serialize(CArchive& ar);

Step 4:

The following code should be added to Serialize() function in the CName class :

void CName::Serialize(CArchive &ar)
{

CObject::Serialize( ar );

if (ar.IsStoring())
{

ar << m_strFirstName << m_strSecondName;}
else
{

ar >> m_strFirstName >> m_strSecondName;

}

}

IMPLEMENT_SERIAL( CName, CObject, 0 )

Step 5:

The following code should be added to Serialize() function in the Document :

void CNamesDoc::Serialize(CArchive& ar)
{

m_NameList.Serialize(ar);

if (ar.IsStoring())
{

// TODO: add storing code here

}
else
{

m_nCurrentPosition = m_NameList.GetHeadPosition();

}

}
