How to store CObArray object arrays in file (Serialize problem)

i want to store recode in file. It is a simple file-based database, with the records sequentially appended to the end of the previous record.

So firstly i made Recde Class , this class object store recode and every recode add in CObArray object arrays ....

but problem ocurse when i want store in file bcoz CObArray object arrays not store in file i am using Serialize but get error when stroring in file...

CArchive ar(&file, CArchive::store);

UpdateData(TRUE);
Recode->SetName(m_Name); // Recode of one person
Recode->SetValue(m_value); // Recode of one person

m_oaPeople.Add(Recode);

//Recode store in CObArray object arrays
m_oaPeople.Serialize(ar); // Here have problem

Guide me

This ASSERT is fired when you class has no DECLARE_SERIAL/IMPLEMENT_SERIAL! I mentioned this in my previous answers!

The schema number is 0xFFFF. Because I see the classname CObject I can see that there is no DECLARE_.../IMPLEMENT_... macro defined for this class at all!

Show the declaration and definition of the class you want to serialize!

What error Please try to be more precisise.

Check the Debug output for information. A lot of infos about problems causes a trace message to appear in the Debug Output Window.

What do you mean does not work properly
When you call Serialize what happens
Give us some code, that we can see what might the fault!

CArchive ar(&file, CArchive::store);

UpdateData(TRUE);
Recode->SetName(m_Name); // Recode of one person
Recode->SetValue(m_value); // Recode of one person

m_oaPeople.Add(Recode);

//Recode store in CObArray object arrays means (m_oaPeople)

m_oaPeople.Serialize(ar); // Here have problem this funtion genrate error at runtime

Thank for fast response

i have alrady done this work means

Recode class derived from CObject

and IMPLEMENT_SERIAL , DECLARE on Recode class

Thhis recode object store in CObArray Object and run time these recode acsess by Index menas

Object [ n ]        n= 1,2..........n n = Totle No of Recode

i want to store these recodes in file  , CObArray Object have recodes so CObArray Object store in file bcoz CObArray class have serialize funtion but this funtion not working properly

1. Did you derived your recode class from CObject

2. Did you used IMPLEMENT_SERIAL and DECLARE_SERIAL on that class
