Woohoo!  Once it sinks in that a class can raise an event, suddenly the
world opens up.  The class can now notify the world that it has finished
doing something, that something is available, that it needs attention etc.

And you are on your way.

Subject: [AccessD] Classes and Events Thanks


I just want to say THANK YOU for the recent discussion on classes and
Events.

I still don't quite have a handle on using events in custom class modules
with form controls yet, but it's slowly starting to sink in. Well, it make
more sense now than it did before.

What I really need to and want to thank you for is opening my mind to custom
classes with custom events. I am currently rewriting a Word export from a VB
App with encapsulated the Word export in a class and I was trying to figure
out how to update a control on the form with status messages. I tried
passing the control to the class, but it didn't like the way I was doing it.
THen all of a sudden I realised that if I rasie an event in the custom
class, and let the form handle the event raised, then I can use ANY control,
and not just a specific type of control to display the status. And what do
you know, I got it working within a couple of minutes.

Raising and handling events is SO powerful.

Really, thanks for opening my eyes to it.
