Visual Basic 6 Problem

Because of the troubles with "built-in" events, I switched to using
java-style events: The server defines an interface that standardizes the
sending and/or receiving of the messages. The clients then have objects
that implement that interface, which are handed to the server. The
server now communicates through those objects.

Best regards

When you said "troubles with built-in events", what did you mean?

Thanks,

I could post the sample code, but you might as well look at the article
yourself.
This is a link to Sharing the CoffeeMonitor, which is step 7 in the VB tutorial
on Creating an Activex Exe Component.

http://msdn.microsoft.com/library/e...ffeemonitor.asp

In summary, it says:

For two apps to both receive the events, they must get a reference to a shared
object, not each create their own new object.

To do this, you create a Connector class. Each app creates its own Connector
object, and the connector has a method for getting a reference to the one shared
RealClass object (the CoffeeMonitor in the example).

The real object is created when the first connector is created, and terminated
when the last connector is terminated. It is set to PublicNotCreatable, so that
each app is forced to use the Connector to get to it.

In each app, the code looks something like

Dim WithEvents RealObj As RealClass
Dim Conn As Connector
Set Conn = New Connector
Set RealObj = Conn.RealObject

Well there is always DDE. It is somewhat out of favor, but is built into VB
and very simple to implement.

When you said "troubles with built-in events", what did you mean?

Sometimes, they just don't fire. When single stepping through the code,
the RaiseEvent command is executed and there is a WithEvents variable
containing an object that should catch it, but nothing is caught. I
could not extract a pattern in when it does work, or when it doesn't.
Mind you, this only happens (so far) when trying to catch events from
objects from another project.
