[Zope] RE: Blobs in Interbase

Tue Aug 2 03:31:25 EDT 2005

Hi Bob,

Thanks again for your reply.

I've tried this approach before, so I'm thinking perhaps its my db adaptor. 
Which one are you using, if you don't mind me asking?

I've had trouble installing kinterbase (it complains about LDAP..?), so at 
the moment I use gvib. I've pencilled in quite a bit of time today to try to 
get kinterbase installed.
Unfortunately I'm on Windows, which I'm guessing contributes to the 
installation problems!

Thanks once again for your help and your time. If this doesn't work, I'll 
look for the Zope-DB list, and basically go and bother someone else.

Cheers

Ashley
