Does anyone know how to create an ActiveX EXE Server that raises events
which can be captured by muliple clients?

So, I have two applications that are both clients. I need to p*** data via
the activex exe from one application to the other. The messages will be
"captured" as in the event handler, the code will check one of the
paramaters that contains a simple string that represents the recipients
"address" (these strings could be just "App1" and "App2".

I've tried to do this but it only raises the event in the application that
is sending the message. I need the event to be raised in both applications.

I have the ActiveX EXE properties set to "MultiUse" and using a Thread Pool
of 1.

Any help or advice would be very welcome as this is really causing me some
problems.

Many thanks,
Darren

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/en...feemonitor.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 cl***. Each app creates its own Connector
object, and the connector has a method for getting a reference to the one shared
RealCl*** 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 RealCl***
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.

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.
