Is there a way for multiple users to read/write to a file at the same
time? I doubt that this would be possible with a text file, but what
about a binary file or database?
What I'm picturing in my head is a group of people using individual
copies of the same application on the same network. The application
displays data in a list box. The data collected is typical file
information such as name, size, modification date, etc. This isn't a
problem. The problem is that the user will be able to customize these
listings with addition information about these files and everyone needs
to be aware of this additional information so that they will know how to
proceed. "This file is to be ignored," "This file is ready for further
action," etc.
If someone edits the information in one of these cells from their copy
of the application, I would like this new information 'immediately'
reflected in the application of anyone else viewing the same data. I
would also like to avoid writing a 'server' application to juggle this
information the group of 'clients' on the network.
If this in anyway plausible, how would you deal with more than one
person trying to edit the data and what would be the best way to achieve
this?
