Security problem

[trasher]

Here's my problem :

I made a program with links and operation to excel files. The user can access all these files by the program. But, I don't want them to access these in any other way (example : windows explorer, etc). For now, I can't set reduced permission to some persons because some files might be updated frequently by a user. I just don't want anyone to be able to delete a file manualy.

I'm using win NT 4.0

If someone have an idea... I'm a newbie in network developement.... :p

You'll want use NTFS permissions to prevent Deleting (you can give read, write, and deny delete). You can password protect the excel files, but I don't think that'll work for you.
