I Store some data from a test in a database (MsAcces). Is it possible to serialize this data in one file. I must store the data from one test in one file. I used the database as a buffer.(No dataloss when there is a powerfaillure).
The data is stored from a DaoRecordView in the database

Did you test MS Access against this no- dataloss? Maybe easier to implement a non-cached system directly.
Anyway, it is pretty simple to export data from an MS Access database 'manually' and this procedure can be automated. All a bit clumsy though.
Another way would be to use ODBC or DAO and get the data back from the database. Powerfailure wouldn't be a problem once it is safely stored in the MDB

Thanks to KangaRoo

I get the data from the dao-database back in a view (I put it in a Datagrid).
It should be possible to Serialize the Datagrid (or the data with the m_pSet->Serialize function), but I don't know how to  do this.
Serializing data only seems to work when you put in the Document
Is it possible to Serialize data in a View without putting it in the Document???

I am not familiar with DAO / MFC only Access (and C++), but if this DataGrid View is supposed to provide a view on some recordset I would doubt is can be 'serialized'. Why would one want to do that.
It should be possible to create some 'RecordSet' with the data, move through it and write out the data.

Hello,

I already found a way to serialize the data. In the document, I've a member from my recordset. So, I get the data and I serialize every datapoint.
To get the data, I made a While-loop, but it didn't work. I had to do it with a for-loop. (I think it was a problem with the member function Set.IsEof())

Thanks for your comment
