send a message to another screen

[Guest]

I would like to have a command button on a form with one user that when
clicked brings up a message on another selected user's screen or several
user's screens.
Is this possible please
Many thanks

Perhaps I'm missing something, but haven't you just described Instant
Messaging? In other words, isn't this feature already built-in to Windows?

Well...

I haven't done this but I have thought about it - what if you had a
table where msg's could be written to, and forms that checked that
table for new msg's on Timer events? Msgbox's could pop-up according
the information and criteria in the table.

The only drawback is that it wouldn't be entirely instant. Simple but.

It could be done, certainly, and as you say it would not be very difficult
to do it. But the timer interval would have to be quite short, so you'd have
multiple PCs querying the database across the network at frequent intervals,
with potential performance implications not only for that specific app, but
for other network traffic too.

I'm not saying that it should never be done, but I think if I was going to
do something like that, I'd want to be sure that, when the network admin
asks me why I'm doing it that way instead of using Instant Messaging, I have
a good answer.
