Could you try to clarify something for me, Peter.
I will create a New() object.
I will then call Init() on that object to set some properties. Init()
will DisableCommit to keep the object active after the Init() returns
(Done bit = false).
I will then call a transactional method that uses the connection string
property.
This method will write to the database and then SetComplete() or
SetAbort() to commit or abort the transaction. This will set the Done
bit = true ... and the object will deactivate(?)
Can I then call another method (possibly the same method) on the object
without having to instantiate and initialise it again? I am thinking of
something like ...
Dim objMyObject as New TransactionalObject()
objMyObject.Init(x,y,z)
For c = 1 TO n
objMyObject.TransactionalMethod(.. , .. , ..)
Next
Thanks
Alan

I should really have said for transactional components. (Since you are
using transactions you are
also using JIT activation implicitly). You'll never want to commit a
transaction after just an
Init call, presumably you'll also have some other work to do, so to mark
this it would be best to
call IObjectControl::DisableCommit. If you don't then the component is
saying 'I'm happy to
commit this transaction' (by default - EnableCommit) when it returns
from Init.
You definitely don't want to call SetComplete or SetAbort in Init which
would allow COM+ to
deactivate your component and lose its state between method calls.
These should only be called
after your real work is complete for the object.
Peter
