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

Question

I work with ActiveX Delphi and Crystal Reports 9.0 objects.

I know that I can load a report from a file as follows:

crApplication.OpenReport (AFileName)

However, I would like to save my report in memory and open it from memory instead of a file. I do not want to create temporary files on my disk.

Any ideas?

Thank you 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 (if there is enough cache available) that is not written to the hard drive and deleted when your application is closed.

There is a BLOG that describes this:
