O$ - FileOps strangeness...

[David Walton]

Kelly,

Seems I am now encountering an issue with the 12 byte header - which  
isn't being read - or written. Don't know how to get windows to read  
it...

Any ideas?

It gives the message that Omnis can't read the library file (the one  
I'm reading and writing).


In brief, here's what I'm doing...

There's a version update button that , when clicked, prompts for a  
library file. The file is read and placed into the database. Then,  
when a client logs in, it fetches the most current library file and  
replaces their local copy. Then it relaunches the library again.

I can look at the binary that is written to the database from windows  
and it doesn't have the 12 byte header. I assume that is causing  
windows to not understand the file type???

Thanks.
