Re: How to update all users when one makes a change

Polling of some kind.  You could have a background thread on your UI that
checks for changes top open record every 30 seconds or so.  We do something
similar with one of our lookup tables that gets cached. We have a 60 second
'poller' that checks for changes, if found the cache is updated.

Subject: [DOTNET-WINFORMS] How to update all users when one makes a
change


Hello,

        I am sure that there is an easy answer to this, just not sure how it
is done using best practice. The problem I have an invoicing system and when
someone adds a new item to someone's order or makes a payment against an
invoice, how do you push that information to all the users who currently
have that record open? Or is it better to not let others open the record
while it is open by someone else? Just looking for a bit of guidance on
this.

Thanks
