'(1) You must create a reference to the Microsoft Transaction Server Type Library (mtxas.dll).
' If using Windows 2000, choose the COM+ Services Library (comsvcs.dll) instead.
'(2) Set your ClassModule's MTSTransactionMode property to 2 - RequiresTransaction
' Note: ONLY use 2 - Requires Transaction if you plan on using the component with an MSDTC-
' compliant Resource Manager such as MSMQ or SQL Server - OTHERWISE, use
' 1 - No Transactions
'(3) Make sure your project's Unattended Execution property is checked
'(4) Make sure your project's Component Version Compatibility is set to Binary Compatibility

' ObjectControl implements the interface that is used by MTS when the object is
' activated and/or deactivated - this happens when you call one of the components's methods
' The ObjectControl implementation makes use of three procedures:
' 1) ObjectControl_Activate
' 2) ObjectControl_CanBePooled
' 3) ObjectControl_Deactivate
'**********************************************************************************************
Implements ObjectControl

Dim objOC As ObjectContext

Public Sub Something()
'This is a user-defined procedure/method
'The ObjectContext Object is returned by GetObjectContext

On Error GoTo Abort

'*******************************************************
' Perform whatever you want in this area
' Visual Basic 6 stuff goes here
' The Something() procedure/method is just
' an example - you may use properties and other
' methods/procedures as well!
