Retaining State in COM+ objects?

[Stephen]

Hi,

Does anyone know if it is possible to retain the state of an object
that uses COM+ transactions?

ie.

obj.Property1 = "something"
obj.DoTransaction

where DoTransaction is defined as:

Public sub DoTransaction()
'get object context

'do a few things
'if any errors call SetAbort

'call SetComplete if no errors
End Sub

its there anyway to keep the value of Property1 after calling
DoTransaction?
I've heard changing the isolation level of the component will make the
component keep its state, but I can't seem to change it.

Bringing up the component's properties, from the Component Services
Console, under the "Transactions" tab, I only see the "Transaction
Support" and "Transaction Timeout" settings. There are no options to
change the isolation level.

I'm running Win2k sp2, VS6 sp5, Sql 2000

TIA

Yes you can.

You can use the Shared Property Manager to do this. The below example uses MTS but I believe the
COM+ implementation uses the same objects.

Yup, COM+ seems to use the same objects.

Thanks!
