Is there a way to load a Crystal Report 9.0 file from a stream?

Question

I am working with Delphi and Crystal Reports 9.0 ActiveX objects.

I know that I can load a report from a file like this:

crApplication.OpenReport(AFileName)

However, I would like to store my report in memory and open it from memory instead of file. I don't want to create any temporary files on my disk.

Any ideas?

Thanks for your time.

This answer comes late, but better late than never...

You can try with a file with attributes FILE_ATTRIBUTE_TEMPORARY and FILE_FLAG_DELETE_ON_CLOSE. Such a file is (if enough cache memory is available) not written on harddisk and deleted when your application is closed.

There is an BLOG which describes this:
