Hi 26578!

One way would be to have the application respond to the presence of specific files in certain folders that you can use for messaging among instances.

You could have an app running at a manager's machine watching this folder (there's a windows api for that, I recall) and then have that watcher raise events to which the main app responds.

The users' apps would place files there that the manager's app would respond to.

I think you can also achieve this with dcom, but am not sure if that works and/or how.

I want to requery another form (the Manager's form I was talking in the first part of my message) when these biz objects save the information. My problem is that these biz objects are children of another biz object. Therefore the main transaction is not yet commited when OnStateChange method of one of these biz objects occurs. How can I solve this problem?
