Hi
We use Metakit to store miscellaneous information for our programe. It works on
windows,
macosx and linux.
It happens that when the database is created on the windows network, we have
some problem
with the windows application (we use metakit-2.4.9.6).
Below you will find a program that creates a file, adds rows, and retrieves
information.
The Find function doesn't return anything and a manuel search also gives no
result. In our
main program, the Find() function remains in an infinite loop.
It works fine with other plateform combinations : from windows client to simple
windows
sharing, from macosx client to windows file server and from macosx client to
macosx apple share
file server.
Thanks for any suggestion about this.
PS: our windows file server is a macosx with Samba. we compile with visual
studio 2005
