CArchive::Flush
Forces any data remaining in the archive buffer to be written to the file.
void Flush( );
Remarks
The member function Flush ensures that all data is transferred from the archive to the file. You must call CFile::Close to complete the transfer from the file to the storage medium.
Example
CFile myFile(_T("CArchive__test__file.txt"),
CFile::modeCreate | CFile::modeWrite);
CArchive ar(&myFile, CArchive::store);
// Write a string to the archive.
ar.WriteString(_T("My string."));
// Flush all of the data to the file.
ar.Flush();
