Solution 1

You better NOT use CArchive, but write data in a file. If you use the standard file API of C likefopen you get portable code.

If you write a struct you use write and you are done.

plz dont use CArchive ;-)

Solution 2

If you are only keeping data in memory then why do you need something as complicated as a CArchive? Use one of the STL container classes[^].

Solution 3

I guess you may use a CMemFile[^] pointer in the CArchive constructor.
