VB,STORED PROC, COM, DTC QUESTION?

Melvin,
1: Release the stored proc by setting the object to nothing

2: I use the follow error handling in my components

Dim conn as ADODB.Connection
Dim cmd as ADODB.Command
Dim prm as ADODB.Parameter

On Error Goto PRoc_Err

'Do my call

GetObjectContext.SetComplete

Proc_Exit:
On error resume next
Set prm = Nothing
set cmd = Nothing
conn.Close
set conn = Nothing
Exit Sub

Proc_Err:
GetObjectContext.SetAbort
Err.Raise vbObjectError,...
Resume Proc_Exit
End Sub

Setting your vote is responsible for releasing transaction locks and the
action commit/rollback. You must still close the connection after your vote.

3: set your vote then destroy your objects.

4: If you call BEGIN TRANSACTION from a MTS/COM+ object that is in a transaction
it will run under DTC because your database transaction is already under
DTC control.
BEGIN DISTRIBUTED TRANSACTION is used by SQL Server to run a transaction
under the control of DTC as oppose to local native transaction support.
This is primarily for running transactions between your local database and
a database on a linked server. An example would be if SQL Server were running
a job that runs against a remote database.
