Firstly thanks to everyone who is contributing to this. This is really
helpful to me and far better than anything I have found in the
documentation so far.
Steve,
Just to clarify, I am using VB.NET and COM+ 1.0
Brent,
I am concerned about your statement
"This object will generally be in its initial (just instantiated
state)."
- are there instances when it wouldn't be in its initial state ? If so,
can objects be pooled still holding their state so that another request
to the object might pick up the wrong state. My main concern here is
with connection strings.
Generally,
Should I be implementing IObjectControl as a matter of course or only if
I want to capture some of the events?
If each method (apart from Init) set EnableCommit() or DisableCommit()
rather than SetComplete() or SetAbort() would my object always hold its
state for future calls by the same caller without having to call Init()
again.
If so, would there then be any mileage in having a Dispose() method on
each class that just called DeactivateOnReturn(). The Dispose() would be
called on the object when it is no longer needed and then it would be
deactivated and pooled.
My original code example would then look like ....
Dim objMyObject as New TransactionalObject()
objMyObject.Init(x,y,z)
For c = 1 TO n
objMyObject.TransactionalMethod(.. , .. , ..)
Next
objMyObject.Dispose()
.. or am I playing with fire here?
Thanks again
Alan

I'd say COM.

LOL. He's talking about COM+
