member this.IsFirstInTransaction : bool
Public ReadOnly Property IsFirstInTransaction As Boolean

Property Value

true if the message was the first message sent in a transaction; otherwise, false.


The message has not been sent. This property can only be read on messages retrieved from a queue.


The message queue is filtered to ignore the IsFirstInTransaction property.


The following code example displays the value of a message's IsFirstInTransaction property.


Receiving applications use the IsFirstInTransaction property to verify that a message was the first message sent in a single transaction to a single queue.

This property is available only with Message Queuing version 2.0 and later.

To verify transaction boundaries, you can use the IsFirstInTransaction property along with two other properties: IsLastInTransaction and TransactionId. Use the former to check whether a message was the last message sent in the transaction, and use the latter to retrieve the identifier of the transaction.

If only one message is sent in a transaction, the IsFirstInTransaction and IsLastInTransaction properties are both set to true.
